Preoperative risk factors for 1-year mortality in patients undergoing fenestrated endovascular aortic aneurysm repair in the US Aortic Research Consortium. J Vasc Surg 2024; 80:724-735.e3. [PMID: 38718849 DOI: 10.1016/j.jvs.2024.04.063] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2024] [Revised: 04/03/2024] [Accepted: 04/15/2024] [Indexed: 06/03/2024]
Abstract
BACKGROUND Early survival (1-year) after elective repair of complex abdominal aortic aneurysms (AAA) or thoracoabdominal aortic aneurysms (TAAA) can be used as an indicator of successful repair and provides a reasonable countermeasure to the annual rupture risk based on diameter. We aimed to identify preoperative factors associated with 1-year mortality after fenestrated or branched endovascular aortic repair (F/BEVAR) and develop a predictive model for 1-year mortality based on patient-specific risk profiles. METHODS The US-Aortic Research Consortium database was queried for all patients undergoing elective F/BEVAR for complex AAA (cAAA) or TAAA from 2005 to 2022. The primary outcome was 1-year survival based on preoperative risk profile. Multivariable Cox regression was used to determine preoperative variables associated with 1-year mortality overall and by extent of aortic pathology. Logistic regression was performed to build a predictive model for 1-year mortality based on number of risk factors present. RESULTS A total of 2099 patients met the inclusion criteria for this study (cAAA: n = 709 [34.3%]; type 1-3 TAAA: n = 777 [37.6%]; type 4-5 TAAA: n = 580 [28.1%]). Multivariable Cox regression identified the following significant risk factors associated with 1-year mortality: current smoker, chronic obstructive pulmonary disease, congestive heart failure (CHF), aortic diameter >7 cm, age >75 years, extent 1-3, creatinine >1.7 mg/dL, and hematocrit <36%. When stratified by extent of aortic involvement, multivariable Cox regression revealed risk factors for 1-year mortality in cAAA (CHF maximum aortic diameter >7 cm, hematocrit <36 mg/dL, and current smoking status), type 1-3 TAAA (chronic obstructive pulmonary disease, CHF, and age >75 years), and type 4-5 TAAA (age >75 years, creatinine >1.7 mg/dL, and hematocrit <36 mg/dL). Logistic regression was then used to develop a predictive model for 1-year mortality based on patient risk profile. Appraisal of the model revealed an area under the curve of 0.64 (P < .001), and an observed to expected ratio of 0.85. CONCLUSIONS This study describes multiple risk factors associated with an increase in 1-year mortality after F/BEVAR. Given that elective repair of cAAA or TAAA is offered to some patients in whom future rupture risk outweighs operative risk, these findings suggest that highly comorbid patients with smaller aneurysms may not benefit from repair. Descriptive and predictive models for 1-year mortality based on patient risk profiles can serve as an adjunct in clinical decision-making when considering elective F/BEVAR.

Survival and Decision-Making in Patients Turned Down for Abdominal Aortic Aneurysm Repair: A Retrospective Study with Focus on COVID-19 Impact. Ann Vasc Surg 2024; 109:522-530. [PMID: 38852773 DOI: 10.1016/j.avsg.2024.03.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2023] [Revised: 03/08/2024] [Accepted: 03/08/2024] [Indexed: 06/11/2024]
Abstract
BACKGROUND To investigate and analyze various aspects related to patients who have been placed on a "turndown list" for elective or emergency repair of abdominal aortic aneurysms. METHODS This retrospective study analyzed data from the Black Country Vascular Network. Multidisciplinary team meetings assessed abdominal aortic aneurysm patients referred through National Abdominal Aortic Aneurysm Screening Program or directly to vascular surgery. Patients considered unfit for intervention were added to a prospectively kept turndown list. Survival and cause of death data were collected, along with cardiopulmonary exercise testing (CPET) results and British Aneurysm Repair scores for some patients. The study covered a period from January 2015 to May 2023. RESULTS After exclusions, 247 (16%) patients were placed on the turndown list with a median age of 85 years (interquartile range 8 years). The mortality of turndown cases on medical grounds was 74.1%. Survival was significantly higher for patients who completed CPET before being turned down (P = 0.004). Gender analysis revealed a higher proportion of females being turned down compared to males (P = 0.044). COVID-19 led to a notable reduction in the number of discussed cases and interventions, while the turndown rates remained consistent. Survival at 1 year in turndown patients was 66%, at 3 years it was 29%, at 4 years it was 18%, and at 7 years it was 5%. Most patients whose cause of death was known died of respiratory complications (30%) or malignancy (19%). British Aneurysm Repair scores and aneurysm size were not significant predictors of mortality. CONCLUSIONS Patients on the turndown list have a substantial mortality rate. A significant proportion of female patients were being turned down compared to men and the reasons for this are not clear. Patients who completed CPET before being turned down had a longer survival time. While COVID-19 impacted healthcare services reducing the number of interventions, it did not influence turndown decisions. The study showed that the cause of death for a significant number of patients was respiratory complications or malignancy.

Herz 2024; 49:210-218. [PMID: 37789149 DOI: 10.1007/s00059-023-05209-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2023] [Revised: 07/10/2023] [Accepted: 09/01/2023] [Indexed: 10/05/2023]
Abstract
BACKGROUND Major vascular surgery is associated with a high perioperative risk and significant mortality. Despite advances in risk stratification, monitoring, and management of perioperative complications, cardiac complications are still common. Stress echocardiography is well established in coronary artery disease diagnostics; however, its prognostic value before high-risk aortic surgery is unknown. This prospective, single-center study compared the outcome of patients undergoing extended cardiac risk assessment before open abdominal aortic surgery with the outcome of patients who had received standard preoperative assessment. METHODS The study included patients undergoing elective open abdominal aortic surgery. Patients who underwent standard preoperative assessment before the start of a dedicated protocol were compared with patients who had extended cardiac risk assessment, including dobutamine stress echocardiography, as part of a stepwise interdisciplinary cardiovascular team approach. The combined primary endpoint was cardiovascular death, myocardial infarction, emergency coronary revascularization, and life-threatening arrhythmia within 30 days. The secondary endpoint was acute renal failure and severe bleeding. RESULTS In total, 77 patients (mean age 68.1 ± 8.1 years, 70% male) were included: 39 underwent standard and 38 underwent cardiac risk assessment. The combined primary endpoint was reached significantly more often in patients before than after implementation of the extended cardiac stratification procedure (15% vs. 0%, p = 0.025). The combined secondary endpoint did not differ between the groups. CONCLUSIONS Patients with extended cardiac risk assessment undergoing elective open abdominal aortic surgery had better 30-day outcomes than did those who had standard preoperative assessment.

A dedicated risk prediction model of 1-year mortality following endovascular aortic aneurysm repair involving the renal-mesenteric arteries. J Vasc Surg 2024; 79:721-731.e6. [PMID: 38070785 DOI: 10.1016/j.jvs.2023.12.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2023] [Revised: 11/29/2023] [Accepted: 12/03/2023] [Indexed: 01/06/2024]
Abstract
OBJECTIVE Treatment goals of prophylactic endovascular aortic repair of complex aneurysms involving the renal-mesenteric arteries (complex endovascular aortic repair [cEVAR]) include achieving both technical success and long-term survival benefit. Mortality within the first year after cEVAR likely indicates treatment failure owing to associated costs and procedural complexity. Notably, no validated clinical decision aid tools exist that reliably predict mortality after cEVAR. The purpose of this study was to derive and validate a preoperative prediction model of 1-year mortality after elective cEVAR. METHODS All elective cEVARs including fenestrated, branched, and/or chimney procedures for aortic disease extent confined proximally to Ishimaru landing zones 6 to 9 in the Society for Vascular Surgery Vascular Quality Initiative were identified (January 2012 to August 2023). Patients (n = 4053) were randomly divided into training (n = 3039) and validation (n = 1014) datasets. A logistic regression model for 1-year mortality was created and internally validated by bootstrapping the AUC and calibration intercept and slope, and by using the model to predict 1-year mortality in the validation dataset. Independent predictors were assigned an integer score, based on model beta-coefficients, to generate a simplified scoring system to categorize patient risk. RESULTS The overall crude 1-year mortality rate after elective cEVAR was 11.3% (n = 456/4053). Independent preoperative predictors of 1-year mortality included chronic obstructive pulmonary disease, chronic renal insufficiency (creatinine >1.8 mg/dL or dialysis dependence), hemoglobin <12 g/dL, decreasing body mass index, congestive heart failure, increasing age, American Society of Anesthesiologists class ≥IV, current tobacco use, history of peripheral vascular intervention, and increasing extent of aortic disease. The 1-year mortality rate varied from 4% among the 23% of patients classified as low risk to 23% for the 24% classified as high risk. Performance of the model in validation was comparable with performance in the training data. The internally validated scoring system classified patients roughly into quartiles of risk (low, low/medium, medium/high and high), with 52% of patients categorized as medium/high to high risk, which had corresponding 1-year mortality rates of 11% and 23%, respectively. Aneurysm diameter was below Society for Vascular Surgery recommended treatment thresholds (<5.0 cm in females, <5.5 cm in males) in 17% of patients (n = 679/3961), 41% of whom were categorized as medium/high or high risk. This subgroup had significantly increased in-hospital complication rates (18% vs 12%; P = .02) and 1-year mortality (13% vs 5%; P < .0001) compared with patients in the low- or low/medium-risk groups with guideline-compliant aneurysm diameters (≥5.0 cm in females, ≥5.5 cm in males). CONCLUSIONS This validated preoperative prediction model for 1-year mortality after cEVAR incorporates physiological, functional, and anatomical variables. This novel and simplified scoring system can effectively discriminate mortality risk and, when applied prospectively, may facilitate improved preoperative decision-making, complex aneurysm care delivery, and resource allocation.

Abstract
BACKGROUND Delay in care of suspected stenosis or thrombosis can increase the chance of losing a functioning hemodialysis access. Access to care and resources were restricted during the COVID-19 pandemic. To evaluate the impact of the pandemic on arteriovenous fistula (AVF) and arteriovenous graft (AVG) procedures we have assessed the number and success of thrombectomies done before and during the COVID-19 pandemic. METHODS We examined all AVF and AVG angiograms with and without interventions, including thrombectomies, performed at a single center during April 2017-March 2021 (pre-COVID-19 era) and April 2020-March 2021 (COVID-19 era). RESULTS The proportion of procedures that were thrombectomies was higher during the COVID-19 era compared to the pre-COVID-19 era (13.3% vs 8.7%, p = 0.009). The proportion of thrombectomy procedures was higher during COVID-19 for AVF (8.2% vs 3.0%, p < 0.001) but there was no difference for AVG (26.5% vs 27%, p = 0.99). There was a trend toward a higher likelihood of unsuccessful thrombectomy during COVID-19 (33.3% vs 20.4%, p = 0.08). CONCLUSIONS More dialysis access thromboses and unsuccessful thrombectomies were noted during the COVID-19 pandemic. This difference could be due to a delay in patients getting procedures to maintain their dialysis accesses.

A novel perspective based on 30-day versus 1-year mortality. Eur J Cardiothorac Surg 2024; 65:ezae041. [PMID: 38318956 DOI: 10.1093/ejcts/ezae041] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/18/2023] [Revised: 01/11/2024] [Accepted: 02/01/2024] [Indexed: 02/07/2024] Open
Abstract
OBJECTIVES The decision to undergo aortic aneurysm repair balances the risk of operation with the risk of aortic complications. The surgical risk is typically represented by perioperative mortality, while the aneurysmal risk relates to the 1-year risk of aortic events. We investigate the difference in 30-day and 1-year mortality after total arch replacement for aortic aneurysm. METHODS This was an international two-centre study of 456 patients who underwent total aortic arch replacement for aneurysm between 2006 and 2020. Our primary end-point of interest was 1-year mortality. Our secondary analysis determined which variables were associated with 1-year mortality. RESULTS The median age of patients was 65.4 years (interquartile range 55.1-71.1) and 118 (25.9%) were female. Concomitantly, 91 (20.0%) patients had either an aortic root replacement or aortic valve procedure. There was a drop in 1-year (81%, 95% confidence interval (CI) 78-85%) survival probability compared to 30-day (92%, 95% CI 90-95%) survival probability. Risk hazards regression showed the greatest risk of mortality in the first 4 months after discharge. Stroke [hazard ratio (HR) 2.54, 95% CI (1.16-5.58)], renal failure [HR 3.59 (1.78-7.25)], respiratory failure [HR 3.65 (1.79-7.42)] and reoperation for bleeding [HR 2.97 (1.36-6.46)] were associated with 1-year mortality in patients who survived 30 days. CONCLUSIONS There is an increase in mortality up to 1 year after aortic arch replacement. This increase is prominent in the first 4 months and is associated with postoperative complications, implying the influence of surgical insult. Mortality beyond the short term may be considered in assessing surgical risk in patients who are undergoing total arch replacement.

[PMID: 37244479 DOI: 10.1016/j.avsg.2023.05.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2023] [Revised: 05/09/2023] [Accepted: 05/10/2023] [Indexed: 05/29/2023]
Abstract
BACKGROUND Mortality after open abdominal aortic aneurysm repair is a quality measure and early death may represent a technical complication or poor patient selection. Our objective was to analyze patients who died in the hospital within postoperative day (POD) 0-2 after elective abdominal aortic aneurysm repair. METHODS The Vascular Quality Initiative was queried from 2003-2019 for elective open abdominal aortic aneurysm repairs. Operations were categorized as in-hospital death on POD 0-2 (POD 0-2 Death), in-hospital death beyond POD 2 (POD ≥3 Death), and those alive at discharge. Univariable and multivariable analyses were performed. RESULTS There were 7,592 elective open abdominal aortic aneurysm repairs with 61 (0.8%) POD 0-2 Death, 156 (2.1%) POD ≥3 Death, and 7,375 (97.1%) alive at discharge. Overall, median age was 70 years and 73.6% were male. Iliac aneurysm repair and surgical approach (anterior/retroperitoneal) were similar among groups. POD 0-2 Death, compared to POD ≥3 Death and those alive at discharge, had the longest renal/visceral ischemia time, more commonly had proximal clamp placement above both renal arteries, an aortic distal anastomosis, longest operative time, and largest estimated blood loss (all P < 0.05). Postoperative vasopressor usage, myocardial infarction, stroke, and return to the operating room were most frequent in POD 0-2 Death and extubation in the operating room was least frequent (all P < 0.001). Postoperative bowel ischemia and renal failure occurred most commonly among POD ≥3 Death (all P < 0.001).On multivariable analysis, POD 0-2 Death was associated with congestive heart failure, prior peripheral vascular intervention, female sex, preoperative aspirin use, lower center volume quartile, renal/visceral ischemia time, estimated blood loss, and older age (all P < 0.05). CONCLUSIONS POD 0-2 Death was associated with comorbidities, center volume, renal/visceral ischemia time, and estimated blood loss. Referral to high-volume aortic centers could improve outcomes.

Abstract
BACKGROUND The endovascular approach to treating ruptured or symptomatic abdominal aortic aneurysms (AAAs) with difficult neck anatomy still poses a major challenge. This study proposes and evaluates the outcomes of a novel technique, Transrenal Endovascular Aneurysm Repair (Tr-EVAR) which utilizes the top ring 'valley' and 'peak' configuration of the Anaconda stent graft to achieve proximal seal in AAAs with an unfavourable neck. METHODS All patients treated with Tr-EVAR over a period of 10 years were identified retrospectively. Demographic, clinical and outcome data were collected, and survival analysis was performed. The time-to-event was analyzed using Kaplan-Meier curves for complication-free survival, reintervention-free survival, and overall survival. RESULTS During the study period, 36 patients ruptured, symptomatic or large AAAs having unfavorable necks and not fit for open repair underwent Tr-EVAR. Two patients died in the first 30 days postprocedure (5.6%). The overall survival at 1 year, 3 years and 5 years were 86%, 72% and 54% respectively with a mean overall survival of 74.0 months (SE 7.8, 95% confidence interval 58.7-89.3) which was comparable to chimney endovascular aneurysm repair (EVAR). The complication-free survival and reintervention-free survival at 1 year, 3 years, and 5 years were 75%, 61%, 42%, 78%, 64%, and 45%, respectively. CONCLUSIONS Tr-EVAR can be considered as an off-the-shelf solution for urgent cases not fit for open repair with unfavourable neck features for standard EVAR. Careful patient selection and planning have generated acceptable immediate, midterm and long-term results comparable to those presented by chimney EVAR in the literature.

Abstract
Background: Knowledge of factors that influence all-cause mortality after endovascular abdominal aortic aneurysm repair (EVAR) could improve therapeutic strategies post-EVAR and thus patient prognosis. Our study aimed to evaluate the association between sociodemographic information, comorbidities, laboratory parameters, treatment, selected anatomical and genetic factors and all-cause mortality post-EVAR. Patients and methods: We reviewed all patients who had undergone elective EVAR for non-ruptured abdominal aortic aneurysm (AAA) between January 2010 and December 2019. AAA size (maximum diameter and volume) was measured using CT-angiography. Sac expansion was defined as at least 5 mm increase, sac regression as at least 5 mm decrease in the sac diameter determined at 36±3 months post-EVAR in relation to pre-EVAR AAA diameter. Adjustments were performed for age, hypertension, diabetes mellitus, dyslipidaemia, sex, smoking, number of lumbar arteries, patency of inferior mesenteric artery and number of reinterventions post-EVAR. Results: One hundred and sixty-two patients (150 men, 12 women) with a mean age of 72.6±7.3 years were included in the analysis. Pre-EVAR AAA diameter (HR 1.07; 95% CI 1.03 - 1.12; p=0.001), pre-EVAR AAA volume (HR 1.01; 95% CI 1.002 - 1.011; p=0.008), post-EVAR sac diameter (HR 1.06; 95% CI 1.03 - 1.10; p=0.000), post-EVAR sac volume (HR 1.01; 95% CI 1.002 - 1.011; p=0.006) and anticoagulation therapy (HR 2.46; 95% CI 1.18 - 5.14; p=0.019) were associated with higher mortality in multivariate analysis. Sac regression (HR 0.42; 95% CI 0.22 - 0.82; p=0.011), and treatment with angiotensin-converting enzyme (ACE) inhibitors or angiotensin II receptor blockers (ARBs) (HR 0.71; 95% CI 0.36 - 0.97; p=0.047) were associated with lower mortality. Conclusions: Greater pre- and post-EVAR diameter and volume, failure of sac regression and anticoagulation were associated with higher mortality post-EVAR. Reduced mortality was observed in patients treated with ACE inhibitors or ARBs, and in patients with AAA sac regression.

Abstract
OBJECTIVE To examine long-term outcomes after endovascular (EVAR) and open repairs (OAR) for intact abdominal aortic aneurysms in Australia, Germany, and the United States, using a unified study design. BACKGROUND Similarities and differences in long-term outcomes after EVAR versus OAR across countries remained unclear, given differences in designs across existing studies. METHODS We identified patients aged >65 years undergoing intact abdominal aortic aneurysm repairs during 2010-2017/2018. We compared long-term patient mortality and reintervention after EVAR and OAR using Kaplan-Meier analyses and Cox regressions. Propensity score matching was performed within each country to adjust for differences in baseline patient characteristics between procedure groups. RESULTS We included 3311, 4909, and 145363 patients from Australia, Germany, and the United States, respectively. The median patient age was 76 to 77 years, and most patients were males (77%-84%). Patient mortality was lower after EVAR than OAR within the first 60 days and became similar at 3-year follow-up (Australia 14.7% vs 16.5%, Germany 18.2% vs 19.7%, United States: 24.4% vs 24.4%). At the end of follow-up, patient mortality after EVAR was higher than OAR in Australia [ hazard ratio (HR) 95% CI: 1.21 (0.96-1.54)] but similar to OAR in Germany [HR 95% CI: 0.92 (0.80-1.07)] and the United States [HR 95% CI: 1.02 (0.99-1.05)]. The risk of reintervention after EVAR was more than twice that after OAR in Australia [HR 95% CI: 2.60 (1.09-6.15)], Germany [HR 95% CI: 4.79 (2.56-8.98)], and the United States [HR 95% CI: 2.67 (2.38-3.00)]. The difference in reintervention risk appeared early in German and United States patients. CONCLUSIONS This multinational study demonstrated important similarities in long-term outcomes after EVAR versus OAR across 3 countries. Variation in long-term mortality and reintervention comparisons indicates possible differences in patient profiles, surveillance, and best medical therapy across countries.

Abstract
OBJECTIVE Endovascular aortic repair (EVAR) as surgical treatment for infective native aortic aneurysm (INAA) is associated with superior survival compared with open surgery, but with the risk of infection related complications (IRCs). This study aimed to assess the association between baseline clinical and computed tomography (CT) features and the risk of post-operative IRCs in patients treated with EVAR for INAA. It also sought to develop a model to predict long term IRCs in patients with abdominal INAA treated with EVAR. METHODS All initial clinical details and CT examinations of INAAs between 2005 and 2020 at a major referral hospital were reviewed retrospectively. The images were scrutinised according to aneurysm features, as well as peri-aortic and surrounding organ involvement. Data on post-operative IRCs were found in the patient records. Cox regression analysis was used to derive predictors for IRCs and develop a model to predict five year IRCs after EVAR in abdominal INAA. RESULTS Of 3 780 patients with the diagnosis of aortic aneurysm or aortitis, 98 (3%) patients were treated with EVAR for abdominal INAAs and were thus included. The mean follow up time was 52 months (range 0 ‒ 163). The mean transaxial diameter was 6.5 ± 2.4 cm (range 2.1 ‒14.7). In the enrolled patients, 38 (39%) presented with rupture. The five year IRC rate in abdominal INAAs was 26%. Female sex, renal insufficiency, positive blood culture, aneurysm diameter, and psoas muscle involvement were predictive of five year IRC in abdominal INAA after EVAR. The model had a C-index of 0.76 (95% CI 0.66 - 0.87). CONCLUSION Pre-operative clinical and CT features have the potential to predict IRC after endovascular aortic repair in INAA patients. These findings stress the importance of rigorous clinical, laboratory, and radiological follow up in these patients.

Abstract
BACKGROUND We aimed to study the discriminative power of 3 comorbidity scores for predicting 5-year survival after the elective repair of aorto-iliac aneurysms (AAA). METHODS 444 patients with AAA undergoing elective repair (33% open and 67% endovascular) between 2000 and 2020 were reviewed. The Charlson Comorbidity Index (CCI) and subsequent adjustments by Schneeweiss, Quan and Armitage, the Modified Frailty Index (MFI) and the American Society of Anesthesiologists Score (ASA) were calculated from preoperative data. Their association with 5-year survival was analyzed using Cox regression models and their discriminative power and its changes with C statistics and Net Reclassification Index (NRI). RESULTS All comorbidity scores were associated with survival after adjusting by age, sex and type of surgical repair: original CCI HR=1.24, P<0.001; Schneeweiss CCI HR=1.23, P<0.001; Quan CCI HR=1.27, P<0.001, Armitage CCI HR=1.46, P<0.001, MFI HR=1.39, P<0.001 and ASA HR=1.68 (P=0.04) and 2.86 (P=0.01) for classes III and IV, respectively. Associated C statistics were of 0.64, 0.65, 0.65, 0.64, 0.61 and 0.59, respectively. Compared with the original CCI, models based on Schneeweiss CCI and Armitage CCI provided minor improvements in NRI (0.32 and 0.23), and the model based on ASA showed lower C statistics (P=0.014) and NRI (-0.30). CONCLUSIONS Established comorbidity scores, such as CCI, MFI or ASA, are all associated with 5-year survival after the elective repair of AAAs, being ASA the worst of them. However, their predictive power is in no case sufficient to identify, by themselves, those patients who may not be eligible for intervention on the basis of life expectancy.

Abstract
OBJECTIVE Chronic kidney disease (CKD) and end-stage renal disease are traditionally associated with worse outcomes after endovascular and open repair of abdominal aortic aneurysm (AAA). This study stratifies outcomes of AAA repair by approach, CKD severity, and dialysis dependence. METHODS All patients undergoing elective infrarenal open aneurysm repair (OAR) and endovascular aortic repair (EVAR) with preoperative renal function data captured by the Vascular Quality Initiative between January 2003 and September 2020 were analyzed. Patients were stratified by CKD class as follows: CKD stages 1 and 2, CKD stage 3a, CKD stage 3b, CKD stages 4 and 5, and dialysis. Primary outcomes were perioperative and 1-year mortality. Predictors of survival were identified by Cox multivariate regression models. RESULTS In total, 53,867 elective AAA repairs were identified: 5396 (10%) OARs and 48,471 (90%) EVARs. Most patients were White (90%) and male (81%), with a mean age of 73 ± 9 years. Patients who underwent EVAR were older and had more comorbidities. The use of elective EVAR for AAA increased from 52% in 2003 to 91% in 2020 (P < .001). The OAR cohort had more perioperative complications and short-term mortality. The CKD 1 and 2 group had the highest 1-year survival compared with the other groups after both OAR and EVAR. On Cox regression analysis, after EVAR, compared with CKD 1 and 2, worsening CKD stage (CKD 3a: hazard ratio [HR], 1.25; 95% confidence interval [CI], 0.93-1.68; P = .13; CKD 3b: HR, 1.74; 95% CI, 1.23-2.45; P < .050; CKD 4-5: HR, 3.23; 95% CI, 2.13-4.88; P < .001), and dialysis (HR, 4.48; 95% CI, 1.90-10.6; P < .001) were independently associated with worse 1-year survival rates. After OAR, compared with CKD 1 and 2, worsening CKD stage (CKD 3a: HR, 1.08; 95% CI, 0.96-1.20; P = .20; CKD 3b: HR, 1.60; 95% CI, 1.41-1.81; P < .001; CKD 4-5: HR, 2.85; 95% CI, 2.39-3.41; P < .001), and dialysis (HR, 3.79; 95% CI, 3.01-4.76; P < .001) were independently associated with worse 1-year survival rates. CONCLUSIONS Regardless of the treatment approach, CKD severity is an important predictor of perioperative and 1-year mortality rates after infrarenal AAA repair and may reflect the natural history of CKD. Open repair is associated with high perioperative mortality risk in patients with CKD stages 4 and 5, as well as end-stage renal disease. Individualization of patient decision-making is especially important in patients with a glomerular filtration rate of less than 45 and perhaps consideration should be given to raising the threshold for elective AAA repair in these patients. Further studies focusing on appropriate size threshold for repair in these patients may be warranted.

Ann Vasc Surg 2022; 88:363-372. [PMID: 36029948 DOI: 10.1016/j.avsg.2022.07.029] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2022] [Revised: 07/03/2022] [Accepted: 07/24/2022] [Indexed: 11/30/2022]
Abstract
OBJECTIVES The aim of this study was to identify risk factors of major adverse cardiac and cerebrovascular events (MACCE) in octogenarians who received elective endovascular aneurysm repair (EVAR). METHODS Consecutive patients aged ≥ 80 years undergoing elective EVAR from 2009 to 2020 were retrospectively evaluated. The primary outcome was long-term MACCE. All independent risk factors for outcomes were determined by multivariate logistic analysis or Cox regression analysis. RESULTS A total of 163 patients were enrolled in this study. The median age was 81 (interquartile range, IQR, 80-84) years and 85.9% (140/163) of them were male. MACCE happened in 2.5% (4/163) patients within 30 days. With median follow-up of 28 (IQR, 15-46) months, the incidence of long-term MACCE was 26.4% (43/163). Arrythmia was significantly associated with long-term MACCE (hazard ratio, HR = 2.64, 95% confidence interval, CI, 1.16-6.03, P = .021). Carotid artery disease was found a significant association with 2-year MACCE (odd ratio, OR = 6.50, 95% CI, 1.07-39.51, P = .042). Besides, we found that arrythmia and congestive heart failure (CHF) were predictors for overall survival (arrythmia, HR = 2.56, 95% CI, 1.05-6.28, P = .039; CHF, HR = 8.96, 95% CI, 2.12-37.79, P = .003). CONCLUSIONS EVAR in octogenarians had acceptable perioperative risk and long-term outcome. Considering high risk of 2-year MACCE, intervention strategy should be more cautious for patients with carotid artery disease. Octogenarians with arrythmia and CHF should receive stricter postoperative management in case of MACCE.

Abstract
Purpose To investigate the prevalence of and risk factors for abdominal aortic aneurysm (AAA) in 65-year-old men in Oslo, Norway. Materials and Methods From May 2011, until September 2019, the annual population of 65-year-old men living in Oslo were invited to an ultrasonographic screening of the abdominal aorta. Candidates received a one-time invitation by mail, including a questionnaire on possible risk factors and comorbidities. Abdominal aortic outer-to-outer diameter and ankle-brachial index were measured by the screening team. Participants were allocated into three groups: non-, sub- and aneurysmal aorta. Written information on recommended follow-up regime was given to participants with an aortic diameter ≥25 mm. Univariate and multivariate analyses of potential risk factors were performed, in addition to descriptive analyses and significance testing. Results In total, 19,328 were invited, 13,215 men were screened, of which 12,822 accepted inclusion in the study. Aortic diameter was registered for 12,810 participants and 330 men had aortic diameter ≥30 mm, giving a prevalence of AAA of 2.6% (95% confidence interval (CI) 2.31-2.86). We identified 4 independent risk factors for AAA: smoking (OR = 3.64, 95% CI 2.90-4.58), hypertension (OR = 1.87, 95% CI 1.49-2.35), BMI >30 (OR = 1.02, 95% CI 1.00-1.03), and diabetes mellitus (OR = 0.52, 95% CI 0.35-0.79), the latter showing an inverse association with AAA growth. A subgroup of 862 men with aortic diameters 25-29 mm had a significantly higher prevalence of BMI >25, smoking and family history of AAA, compared to participants with aortic diameter <25 mm. Conclusion Among the participants in this study, the prevalence of abdominal aortic aneurysms was 2.6%. Participants with AAA more frequently reported cardiovascular risk factors, and less frequently diabetes mellitus.

Abstract
OBJECTIVE The aim of the COVER Study is to identify global outcomes and decision making for vascular procedures during the pandemic. BACKGROUND DATA During its initial peak, there were many reports of delays to vital surgery and the release of several guidelines advising later thresholds for vascular surgical intervention for key conditions. METHODS An international multi-center observational study of outcomes after open and endovascular interventions. RESULTS In an analysis of 1103 vascular intervention (57 centers in 19 countries), 71.6% were elective or scheduled procedures. Mean age was 67 ± 14 years (75.6% male). Suspected or confirmed COVID-19 infection was documented in 4.0%. Overall, in-hospital mortality was 11.0% [aortic interventions mortality 15.2% (23/151), amputations 12.1% (28/232), carotid interventions 10.7% (11/103), lower limb revascularisations 9.8% (51/521)]. Chronic obstructive pulmonary disease [odds ratio (OR) 2.02, 95% confidence interval (CI) 1.30-3.15] and active lower respiratory tract infection due to any cause (OR 24.94, 95% CI 12.57-241.70) ware associated with mortality, whereas elective or scheduled cases were lower risk (OR 0.4, 95% CI 0.22-0.73 and 0.60, 95% CI 0.45-0.98, respectively. After adjustment, antiplatelet (OR 0.503, 95% CI: 0.273-0.928) and oral anticoagulation (OR 0.411, 95% CI: 0.205-0.824) were linked to reduced risk of in-hospital mortality. CONCLUSIONS Mortality after vascular interventions during this period was unexpectedly high. Suspected or confirmed COVID-19 cases were uncommon. Therefore an alternative cause, for example, recommendations for delayed surgery, should be considered. The vascular community must anticipate longer term implications for survival.

Prognostic Value of Inflammatory Biomarkers in 5-Year Survival After Endovascular Repair of Abdominal Aortic Aneurysms in a Predominantly Male Cohort: Implications for Practice. World J Surg 2021; 45:1949-1955. [PMID: 33721070 DOI: 10.1007/s00268-021-06051-1] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 02/07/2021] [Indexed: 12/15/2022]
Abstract
BACKGROUND Prognostic factors of long-term survival can guide selection of patients for endovascular repair of abdominal aortic aneurysms (EVAR). The aim of this study was to evaluate the relationship between the neutrophil-to-lymphocyte ratio (NLR), the platelet-to-lymphocyte ratio (PLR), the lymphocyte-to-monocyte ratio (LMR) and the systemic immune-inflammation index (SIII) with survival after EVAR and to assess whether the addition of these biomarkers improved the prediction of survival after surgery. METHODS Retrospective analysis of 284 consecutive patients who underwent an EVAR at a single institution. The association between biomarkers and survival was explored using generalized additive models with penalized smoothing splines and multivariate Cox models. C-statistics and continuous net reclassification indexes (c-NRI) were used to assess the improvement in prediction. RESULTS Survival rates at 2 and 5 years were 83.9% and 66.2%, respectively. The predictive score of survival included hemoglobin (HR = 0.849, p = 0.004), statin intake (HR = 0.538, p = 0.004), atrial fibrillation (HR = 2.515, p < 0.001), heart failure (HR = 2.542, p = 0.017) and the non-revascularized coronary artery disease (HR = 2.163, p = 0.004). Spline analyses showed a linear relationship between survival and NLR, PLR, LMR and SII. After adjusting for the predictive score, there was an independent relationship between survival and NLR (HR = 1.072, p = 0.006), PLR (HR = 1.002, p = 0.014) and SII (HR = 1.000, p = 0.043). However, only the addition of NLR improved moderately the c-NRI. A NLR ≥ 3 was independently associated with lower survival rates at 2-years (HR 1.98; 95% CI 1.07-3.66) and 5-years (HR 1.84, 95% CI 1.22-2.78) of follow-up. CONCLUSIONS Most inflammatory biomarkers are linear and independently associated with survival after EVAR, but only the NLR improved moderately the prediction of a survival score. Therefore, a NLR ≥ 3 may be used to identify patients with a low survival rate and help in decision-making.

Abstract
Importance Patients undergoing vascular surgery are at high risk of postoperative myocardial infarction (POMI). Postoperative myocardial infarction is independently associated with significant risk of in-hospital mortality. Objective To examine the association of patient and procedural characteristics with the risk of POMI after vascular surgery and determine the association of evidence-based therapies with longer-term outcomes. Design, Setting, and Participants A retrospective cohort study of prospectively collected data within a statewide quality improvement collaborative database between January 2012 and December 2017. Patient demographics, comorbid conditions, and perioperative medications were captured. Patients were grouped according to occurrence of POMI. Univariate analysis and logistic regression were used to identify factors associated with POMI. The collaborative collects data from private and academic hospitals in Michigan. Patients undergoing major vascular surgery, defined as endovascular aortic aneurysm repair, open abdominal aortic aneurysm, peripheral bypass, carotid endarterectomy, or carotid artery stenting were included. Analysis began December 2018. Main Outcomes and Measures The presence of a POMI and 1-year mortality. Results Of 26 231 patients identified, 16 989 (65.8%) were men and the overall mean (SD) age was 69.35 (9.89) years. A total of 410 individuals (1.6%) experienced a POMI. Factors associated with higher rates of POMI were age (odds ratio [OR], 1.032 [95% CI, 1.019-1.045]; P < .001), diabetes (OR, 1.514 [95% CI, 1.201-1.907]; P < .001), congestive heart failure (OR, 1.519 [95% CI, 1.163-1.983]; P = .002), valvular disease (OR, 1.447 [95% CI, 1.024-2.046]; P = .04), coronary artery disease (OR, 1.381 [95% CI, 1.058-1.803]; P = .02), and preoperative P2Y12 antagonist use (OR, 1.37 [95% CI, 1.08-1.725]; P = .009). Procedurally, open abdominal aortic aneurysm (OR, 4.53 [95% CI, 2.73-7.517]; P < .001) and peripheral bypass (OR, 2.375 [95% CI, 1.818-3.102]; P < .001) were associated with the highest risk of POMI. After POMI, patients were discharged and received evidence-based therapy with high fidelity, including β-blockade (296 [82.7%]) and antiplatelet therapy (336 [95.7%]). A high portion of patients with POMI were dead at 1 year compared with patients without POMI (113 [37.42%] vs 993 [5.05%]; χ2 = 589.3; P < .001). Conclusions and Relevance Despite high rates of discharge with evidence-based therapies, the long-term burden of POMI is substantial, with a high mortality rate in the following year. Patients with diabetes mellitus, coronary artery disease, congestive heart failure, and valvular disease warrant additional consideration in the preoperative period. Further, aggressive strategies to treat patients who experience a POMI are needed to reduce the risk of postoperative mortality.

Abstract
OBJECTIVE Databases are essential in evaluating surgical outcomes and gauging the implementation of new techniques. However, there are important differences in how data from administrative databases and surgical quality improvement (QI) registries are collected and interpreted. Therefore, we aimed to compare trends, demographics, and outcomes of open and endovascular abdominal aortic aneurysm (AAA) repair in an administrative database and two QI registries. METHODS We identified patients undergoing open and endovascular repair of intact and ruptured AAAs between 2012 and 2015 within the National Inpatient Sample (NIS), the National Surgical Quality Improvement Program (NSQIP), and the Vascular Quality Initiative (VQI). We described the differences and trends in overall AAA repairs for each data set. Moreover, patient demographics, comorbidities, mortality, and complications were compared between the data sets using Pearson χ2 test. RESULTS A total of 140,240 NIS patients, 10,898 NSQIP patients, and 26,794 VQI patients were included. Ruptured repairs composed 8.7% of NIS, 11% of NSQIP, and 7.9% of VQI. Endovascular aneurysm repair (EVAR) rates for intact repair (range, 83%-84%) and ruptured repair (range, 51%-59%) were similar in the three databases. In general, rates of comorbidities were lower in NIS than in the QI registries. After intact EVAR, in-hospital mortality rates were similar in all three databases (NIS 0.8%, NSQIP 1.0%, and VQI 0.8%; P = .06). However, after intact open repair and ruptured repair, in-hospital mortality was highest in NIS and lowest in VQI (intact open: NIS 5.4%, NSQIP 4.7%, and VQI 3.5% [P < .001]; ruptured EVAR: NIS 24%, NSQIP 20%, and VQI 16% [P < .001]; ruptured open: NIS 36%, NSQIP 31%, and VQI 26% [P < .001]). After stratification by intact and ruptured presentation and repair strategy, several discrepancies in morbidity rates remained between the databases. Overall, the number of cases in NSQIP represents 7% to 8% of the repairs in NIS, and the number of cases in VQI grew from 12% in 2012 to represent 23% of the national sample in 2015. CONCLUSIONS NIS had the largest number of patients as it represents the nationwide experience and is an essential tool to evaluate trends over time. The lower in-hospital mortality seen in NSQIP and VQI questions the generalizability of the studies that use these QI registries. However, with a growing number of hospitals engaging in granular QI initiatives, these QI registries provide a valuable resource to potentially improve the quality of care provided to all patients.

Abstract
PURPOSE The long-term outcomes of surgery followed by delirium after multimodal prehabilitation program are largely unknown. We conducted this study to assess the effects of prehabilitation on 1-year mortality and of postoperative delirium on 1-year mortality and functional outcomes. METHODS The subjects of this study were patients aged ≥ 70 years who underwent elective surgery for abdominal aortic aneurysm (AAA) or colorectal cancer (CRC) between January 2013, and June 2018. A prehabilitation program was implemented in November 2015, which aimed to optimize physical health, nutritional status, factors of frailty and preoperative anemia prior to surgery. The outcomes were assessed as mortality after 6 and 12 months, compared between the two treatment groups; and mortality and functional outcomes, compared between patients with and those without delirium. RESULTS There were 627 patients (controls N = 360, prehabilitation N = 267) included in this study. Prehabilitation did not reduce mortality after 1 year (HR 1.31 [95% CI 0.75-2.30]; p = 0.34). Delirium was significantly associated with 1-year mortality (HR 4.36 [95% CI 2.45-7.75]; p < 0.001) and with worse functional outcomes after 6 and 12 months (KATZ ADL p = 0.013 and p = 0.004; TUG test p = 0.041 and p = 0.011, respectively). CONCLUSIONS The prehabilitation program did not reduce 1-year mortality. Delirium and the burden of comorbidity are both independently associated with an increased risk of 1-year mortality and delirium is associated with worse functional outcomes.

Abstract
Abdominal aortic aneurysm (AAA) is an asymptomatic condition due to the dilation of abdominal aorta along with progressive wall degeneration, where rupture of AAA is life-threatening. Failures of AAA endovascular repair (EVAR) reflect our inadequate knowledge about the complex interaction between the aortic wall and medical devices. In this regard, we are presenting a hydrogel-based anthropomorphic mockup (AMM) to better understand the biomechanical constraints during EVAR. By adjusting the cryogenic treatments, we tailored the hydrogel to mimic the mechanical behavior of human AAA wall, thrombus and abdominal fat. A specific molding sequence and a pressurizing system were designed to reproduce the geometrical and diseased characteristics of AAA. A mechanically, anatomically and pathologically realistic AMM for AAA was developed for the first time, EVAR experiments were then performed with and without the surrounding fat. Substantial displacements of the aortic centerlines and vessel expansion were observed in the case without surrounding fat, revealing an essential framework created by the surrounding fat to account for the interactions with medical devices. In conclusion, the importance to consider surrounding tissue for the global deformation of AAA during EVAR was highlighted. Furthermore, potential use of this AMM for medical training was also suggested.

Five-year results of endovascular aortic repair used according to instructions for use give a good general outcome for abdominal aortic aneurysm. SAGE Open Med 2019; 7:2050312119853434. [PMID: 31205704 PMCID: PMC6535726 DOI: 10.1177/2050312119853434] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2019] [Accepted: 05/07/2019] [Indexed: 11/16/2022] Open
Abstract
Objectives: The primary aim of this study was to investigate the rate of sac enlargement and secondary procedures after 5 years when instructions for use are strictly applied with endovascular aortic repair. The secondary aim was to investigate if strict indications with endovascular aortic repair, rendering more open operations, would change the general outcome of patients with abdominal aortic aneurysm. Materials and methods: Patients having their abdominal aortic aneurysm procedure in a single institution between 01 January 2002 and 31 December 2006 were included. Indications for endovascular aortic repair were as follows: aortic neck: length 15 mm or more, diameter 32 mm or less and straight configuration; iliac arteries: length > 10 mm, 7.5–20 mm in diameter. Sac enlargement was defined as an increase in diameter of 5 mm or more. Results: A total of 123 patients were intended to be treated electively with endovascular aortic repair from 2002 to 2007 using Cook Zenith stent grafts. In the same period, 147 patients were treated with elective open repair. At 5 years, 7.3% (N = 9) of the elective intended-to-treat patients with endovascular aortic repair had a sac enlargement. Thirty-five percent of the patients were registered with endoleaks, 13% of the patients had secondary procedures, 12.2% of the patients had early and 6.5% late complications during the follow-up period. Aneurysm rupture was seen in 1.6% of the patients. During the 5-year follow-up period, 34 (27.6%) of the endovascular aortic repair patients died. Five-year mortality for open repair was 23.8%, and 12.2% of the open repair patients had secondary procedures. Conclusion: Endovascular aortic repair for abdominal aortic aneurysm in accordance with instructions for use gives a low long-term risk for increased diameter and low rate of secondary procedures. There was similar mortality after elective endovascular aortic repair and open repair for abdominal aortic aneurysm. Applying endovascular aortic repair according to instructions for use does not seem to change the general outcome of patients with abdominal aortic aneurysm but improves the outcome with the method.

Abstract
OBJECTIVE Most would agree that at least 1-year survival is necessary after intact abdominal aortic aneurysm (AAA) repair to appropriately justify the cost and risk of the procedure. No validated clinical decision instruments exist to predict survival after endovascular aneurysm repair (EVAR) beyond the perioperative period. The purpose of this analysis was to create a preoperative prediction model for 1-year mortality after EVAR for intact AAA in the Society for Vascular Surgery Vascular Quality Initiative. METHODS All intact EVARs in the Society for Vascular Surgery Vascular Quality Initiative from 2011 to 2015 were randomly divided into training (n = 17,836) and validation (n = 2500) data sets, and 31 preoperative candidate predictors were identified. A logistic regression model for 1-year mortality was created, and bootstrapped stepwise variable elimination was used to reduce this model to a best subset of predictors. Penalized maximum likelihood estimation was used to correct for potential overfitting. The final model was internally validated by bootstrapping the area under the curve (AUC) and the calibration slope and intercept, and its performance when applied to the training and validation data sets was compared. RESULTS After elective and nonelective (symptomatic, intact) EVAR, 1-year mortality was 5.5% (n = 900/16,411) and 11.4% (n = 162/1425), respectively. The mean probability of 1-year mortality was 6.0% (n = 1062) in the training set and 5.7% (n = 143) in the validation cohort (P = .12). Significant preoperative predictors of 1-year mortality included chronic obstructive pulmonary disease, age, preoperative renal insufficiency (creatinine concentration ≥1.8 mg/dL or on hemodialysis), ejection fraction <50%, transfer status, body mass index <24 kg/m2, preoperative beta-blocker exposure, larger AAA diameter, and lower admission hemoglobin level. Preoperative statin use was found to be protective. The bias-corrected AUC was 0.759 (Hosmer-Lemeshow goodness-of-fit P value of 0.36; calibration intercept, -0.003; slope, 0.999). When applied to the validation data set, the model had AUC of 0.724 (95% confidence interval, 0.676-0.768; calibration intercept, 0.0009; slope, 0.970), which was in excellent agreement with the original data set bias-corrected AUC. Notably, ∼27.5% (n = 4902) had four or more risk factors with a predicted 1-year post-EVAR mortality risk of 10% to 22% despite that 33.2% of these patients had AAA diameters below recommended treatment guideline minimum thresholds. CONCLUSIONS This validated preoperative prediction model for 1-year mortality identifies patients less likely to benefit from EVAR. Appropriateness of intact AAA EVAR care delivery can be improved by use of this clinical decision aid to determine which high-risk patients have lower probability of mortality within the first postoperative year relative to their predicted annualized rupture risk.

Sarcopenia predicts mortality and adverse outcomes after endovascular aneurysm repair and can be used to risk stratify patients. J Vasc Surg 2019; 70:1576-1584. [PMID: 30852041 DOI: 10.1016/j.jvs.2018.12.038] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2018] [Accepted: 12/12/2018] [Indexed: 01/27/2023]
Abstract
BACKGROUND Endovascular aneurysm repair (EVAR) is currently the most common treatment of abdominal aortic aneurysms. Potential predictors of long-term survival after EVAR include physiologic, functional, and cognitive status, but assessments of these conditions have been difficult to standardize. Objective radiographic findings, such as skeletal muscle atrophy, or sarcopenia, may provide an additional means for selection of patients. This study investigates sarcopenia as a method to predict 1-year survival in patients undergoing EVAR. METHODS A single-institution retrospective review was conducted of all patients who underwent elective EVAR from September 2002 to June 2014. Patients with an available periprocedural computed tomography (CT) scan and clinical data were included in the analysis. Normalized total psoas cross-sectional area (nTPA) was measured on axial CT images using the area of the bilateral psoas muscle at the third lumbar vertebral level normalized to the square of patient height. A threshold for optimal estimate of sarcopenia based on nTPA was determined using a receiver operating characteristic curve. Sarcopenia was evaluated as an independent risk predictor using univariate, multivariate, and survival analysis. RESULTS A total of 272 EVAR-treated patients were evaluated, including 237 men and 35 women with a median age of 72 years and mean body mass index of 28.6 kg/m2. There was a significant increase in overall mortality in patients in the lowest quartile of nTPA (Q1, 23.53%; Q2, 13.24%; Q3, 7.35%; Q4, 5.88%; P = .01). The estimated nTPA threshold for increased mortality after EVAR was 500 mm2/m2. Using this threshold, sarcopenia accounted for 57% of the risk effect in our 1-year survival model. CONCLUSIONS Sarcopenia can assist in identifying EVAR candidates who are less likely to benefit from surgery. It can be readily evaluated from preoperative CT scans and may be a useful tool in evaluation of abdominal aortic aneurysm patients with applications in risk evaluation and telemedicine.

Abstract
BACKGROUND Anatomic severity grade (ASG) can be used to assess abdominal aortic aneurysm (AAA) anatomic complexity. High ASG is associated with complications following endovascular repair of AAAs and we have demonstrated that ASG correlates with resource utilization. The hypothesis of this study is that ASG is directly related to midterm mortality in patients undergoing AAA repair. METHODS Patients who underwent infrarenal AAA repairs between July 2007 and August 2014 were retrospectively reviewed and ASG scores were calculated using 3-dimensional computed tomography reconstructions. Perioperative mortalities (≤30 days) were excluded. The ASG value of 15 was chosen based on previous receiver-operator curve analysis, which showed that an ASG of 15 was predictive of postoperative complications and resource utilization. The 5-year survivors and mortalities were compared utilizing comorbidities, pharmacologic variables, and anatomic variables at or above the defined threshold. RESULTS A total of 402 patients (80% male and 96% Caucasian) with complete anatomic and survival data were included in the analysis. Mean ASG and age at the time of repair were 16 ± 0.15 and 73 ± 0.43 years old, respectively. The 5-year mortality was significantly associated with ASG >15 (hazard ratio [HR]: 1.504, confidence interval [CI]: 1.077-2.100, P < .017), hyperlipidemia (HR: 1.987, CI: 1.341-2.946, P < .001), coronary artery disease (HR: 1.432, CI: 1.037-1.978, P < .029), and chronic obstructive pulmonary disease (HR: 1.412, CI: 1.027-1.943, P < .034). Kaplan-Meier analysis demonstrated improved survival in the low score ASG ≤15 group at 1, 3, and 5 years (96% vs 93%, 81% vs 69%, and 53% vs 41%; P = .0182; Figure 1). CONCLUSIONS Increasing aortic anatomic complexity as characterized by ASG >15 is an independent predictor of midterm mortality following elective infrarenal AAA repair. Therefore, it may be a useful tool for appropriate patient selection and risk stratification prior to elective infrarenal AAA repair.

Abstract
BACKGROUND An anatomic severity grade (ASG) score to categorize and to define anatomic factors for abdominal aortic aneurysm (AAA) repair was proposed. Other studies have previously reported that aortic anatomic complexity is a marker of survival and resource utilization after repair, although it remains unclear whether individual components of the ASG score independently contribute to survival. This study analyzed and validated an aortic and iliac artery calcium scoring system that can potentially predict survival after AAA repair. METHODS Patients who underwent infrarenal AAA repairs from July 2007 to May 2012 were analyzed using complete 5-year records. Those who died ≤30 days of surgery were excluded. Calcium score (CS) was defined using the ASG scoring system for its basis by preoperative imaging <6 months before surgery. A CS for any patient was 0 to 5 points, the sum of the points assigned to aortic neck (2 points total) and iliac artery (3 points total) calcification. A receiver operating characteristic curve was used to determine a CS threshold for mortality. The 5-year survivors and deaths were compared in regard to comorbidities, pharmacology, and CS at or above the defined threshold. Each variable with a P value <.1 between the groups was then placed into a Cox proportional hazards model, with statistical significance of P < .05. RESULTS There were 356 patients who underwent AAA repair with complete 5-year follow-up data; 26% died within 5 years of surgery. Of these, 13% had CS of 0 with 15% mortality, 28% had CS of 1 with 21% mortality, 24% had CS of 2 with 24% mortality, 23% had CS of 3 with 35% mortality, 10% had CS of 4 with 40% mortality, and 2% had CS of 5 with 17% mortality. The receiver operating characteristic curve demonstrated an appropriate threshold of CS 3. Of these patients, 65% had a CS <3, whereas 35% had a CS ≥3. Patients with a CS ≥3 had a lower 5-year survival probability (P = .003). Comparing 5-year survivors and deaths in a Cox proportional hazards analysis, CS ≥3 was associated with a hazard ratio of 1.579 (95% confidence interval, 1.038-2.402; P = .0328). CONCLUSIONS A CS ≥3 is linked to a lower 5-year survival after AAA repair in our population. This system potentially can be another measure for risk stratification and serve as a means to predict midterm mortality in AAA repairs. Future study will be needed for further validation to predict midterm mortality and to better guide surgical decision-making.

Patients with end-stage renal disease have poor outcomes after endovascular abdominal aortic aneurysm repair. J Vasc Surg 2018; 69:405-413. [PMID: 29945838 DOI: 10.1016/j.jvs.2018.04.031] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2017] [Accepted: 04/09/2018] [Indexed: 02/03/2023]
Abstract
OBJECTIVE Although endovascular repair of abdominal aortic aneurysms (AAAs) has been demonstrated to have favorable outcomes, not all cohorts of patients with AAA fare equally well. Our goal was to investigate perioperative and 1-year outcomes in patients with end-stage renal disease (ESRD) on dialysis, who have traditionally fared worse after vascular interventions, to assess how ESRD affects outcomes in a large modern cohort of endovascular aneurysm repair (EVAR) patients. METHODS The Vascular Quality Initiative database was queried for all patients undergoing EVAR from 2010 to 2017. ESRD patients were compared with patients not on dialysis. Propensity-matched scoring and multivariable analysis were used to isolate the effects of ESRD. RESULTS Of 28,683 EVARs identified, there were 321 (1.12%) patients with ESRD on dialysis. Patients with ESRD had no difference in presenting AAA size (57.5 ± 12.7 mm vs 56.7 ± 17.2 mm; P = .44); however, they had more urgent/emergent repairs (20.6% vs 13.6%; P = .002) than those without ESRD. ESRD patients were more often younger, nonwhite, and nonobese and less likely to have commercial insurance (P < .05). ESRD patients more often had hypertension, coronary artery disease, congestive heart failure, previous lower extremity bypass, aneurysm repair, and carotid interventions (P < .05). There was no difference in the rate of concomitant procedures. Matching based on demographics, comorbidities, and operative details showed that ESRD patients had longer hospital length of stay (4.8 ± 9.4 days vs 4.1 ± 12.6 days; P = .026) and higher 30-day mortality (7% vs 2.4%; P < .001). There was no difference in cardiac, pulmonary, lower extremity, bowel, and stroke complications or return to the operating room. On multivariable analysis, ESRD was associated with 30-day mortality (odds ratio, 4.1; 95% confidence interval, 2.6-6.7; P < .001). Of the 24,750 elective EVARs, 1.04% had ESRD on dialysis. Matched data for elective EVAR show increased postoperative length of stay, hospital mortality, and 30-day mortality for ESRD patients on dialysis compared with those who are not. There was no association with postoperative myocardial infarction or pulmonary complications. At 1 year, patients with ESRD on dialysis had worse survival (78% vs 94%; P < .001), and ESRD was associated with higher mortality (hazard ratio, 3.3; 95% confidence interval, 2.5-4.2; P < .001). CONCLUSIONS Among patients undergoing EVAR, ESRD is independently associated with higher perioperative and 1-year mortality despite not being associated with higher postoperative complications. This should be taken into account during informed consent for EVAR and risk-benefit considerations in this high-risk population, particularly for elective repair.

Abstract
Background and Aims: Abdominal aortic aneurysm is a degenerative vascular pathology with high mortality due to its rupture, which is why timely treatment is crucial. The current single-center retrospective study was undertaken to analyze short- and long-term all-cause mortality after operative treatment of abdominal aortic aneurysm and to examine the factors that influence outcome. Material and Methods: The data of all abdominal aortic aneurysm patients treated with open repair or endovascular aneurysm repair in 2004–2015 were retrospectively retrieved from the clinical database of Tartu University Hospital. The primary endpoint was 30-day, 90-day, and 5-year all-cause mortality. The secondary endpoint was determination of the risk factors for mortality. Results and Conclusion: Elective abdominal aortic aneurysm repair was performed on 228 patients (mean age 71.8 years), of whom 178 (78%) were treated with open repair and 50 (22%) with endovascular aneurysm repair. A total of 48 patients with ruptured abdominal aortic aneurysm were treated with open repair (mean age 73.8 years) at the Department of Vascular Surgery, Tartu University Hospital, Estonia. Mean follow-up period was 4.2 ± 3.3 years. In patients with elective abdominal aortic aneurysm, 30-day, 90-day, and 5-year all-cause mortality rates were 0.9%, 2.6%, and 32%, respectively. In multivariate analysis, the main predictors for 5-year mortality were preoperative creatinine value and age (p < 0.05). In patients with ruptured abdominal aortic aneurysm, 30-day, 90-day, and 5-year all-cause mortality rates were 22.9%, 33.3%, and 55.1%, respectively. In multivariate analysis, the risk factors for 30-day mortality in ruptured abdominal aortic aneurysm were perioperative hemoglobin and lactate levels (p < 0.05). According to this study, the all-cause mortality rates of elective abdominal aortic aneurysm and ruptured abdominal aortic aneurysm at our hospital were comparable to those at other centers worldwide. Even though some variables were identified as potential predictors of survival, the mortality rates after ruptured abdominal aortic aneurysm remain high. Early diagnosis, timely treatment, and detection of the risk factors for abdominal aortic aneurysm progression would improve survival in patients with abdominal aortic aneurysm.

Abstract
BACKGROUND Individuals treated for abdominal aortic aneurysms (AAAs) are high-risk patients in whom better risk prediction could improve survival. Contemporary serum lipid parameters, such as apolipoproteins and lipoprotein subfractions, may improve or complement the prognostic value of traditional serum lipids. The aim of this study was to ascertain the extended serum lipid profiles, long-term prognosis and their association in AAA patients. METHODS Altogether 498 patients treated for AAAs and with available serum lipid values were retrospectively analysed. Contemporary lipid parameters were estimated using a neural network model, the extended Friedewald formula. RESULTS Younger age, smoking and urgent or emergency surgery were associated with an unfavourable, and coronary disease and previous stroke with a favourable lipid profile. In multivariable analysis-in addition to advanced age, aneurysm rupture, smoking, pulmonary disease and diabetes-high triglycerides and traditional LDL cholesterol were significant independent risk factors for mortality, HR 1.84 (95% CI 1.20-2.81) and 1.79 (95% CI 1.18-2.73), respectively, while higher EFW-IDL cholesterol was associated with better survival, HR 0.31 (95% CI 0.19-0.65). Including serum lipid parameters improved the prediction of 5-year survival (NRI = 17.7%, p = 0.016). CONCLUSIONS Extended serum lipid parameters complement risk prediction of patients treated for AAAs. An unfavourable lipid profile is associated with treatment of AAA earlier in life and with inferior long-term survival.

Abstract
OBJECTIVES The aim was to assess the survival of patients who had been turned down for repair of an abdominal aortic aneurysm (AAA) and to examine the factors influencing this. METHODS This was a retrospective observational study of a prospectively maintained database of all patients turned down for AAA intervention by the Black Country Vascular Network multidisciplinary team (MDT) from January 2013 to December 2015. Data on AAA size, cardiopulmonary exercise testing (CPET) and cause of death were recorded. RESULTS There were 112 patients. The median age at turndown was 83.9 years (IQR 10.2 years). The median AAA size at turndown was 63 mm (IQR 16.7 mm). The median follow-up time after turndown was 324 days (IQR 537.5 days). Sixty-four patients (57.1%) were deceased after 2 years, with a median survival time of 462 days (IQR 579 days). Patients who died had a significantly larger AAA dimension (median 65 mm, IQR 18.5 mm) than those surviving to date (median 59 mm, IQR 10 mm, p = .004). Using Cox regression analysis, the probability of 1 year survival in the whole population was 0.614. The probability of 2 year survival was 0.388. When accounting for age, gender, AAA dimension, and British Aneurysm Repair risk score, no factors had significant influence over survival. Of the 64 deceased patients, 30 had an accessible cause of death: 36.7% of these were due to ruptured AAAs. There was no significant difference in AAA size between those dying of ruptures and those dying of other causes (p = .225, mean 74 mm and 67 mm respectively). CONCLUSIONS Being turned down for AAA repair carries a significant short-term risk of mortality. Those turned down for repair carried significant levels of comorbid disease but no factors considered were found to be independently predictive of the length of survival.

Abstract
IMPORTANCE Acute kidney injury (AKI) affects as many as 40% of patients undergoing surgery and is associated with increased all-cause mortality. Chronic kidney disease (CKD) is a well-known risk factor for cardiovascular mortality. OBJECTIVE To determine the association between kidney disease and long-term cardiovascular-specific mortality after vascular surgery. DESIGN, SETTING, AND PARTICIPANTS A single-center cohort of 3646 patients underwent inpatient vascular surgery from January 1, 2000, to November 30, 2010, at a tertiary care teaching hospital. To determine cause-specific mortality for patients undergoing vascular surgery, a proportional subdistribution hazards regression analysis was used to model long-term cardiovascular-specific mortality while treating any other cause of death as a competing risk. Kidney disease constituted the main covariate after adjusting for baseline patient characteristics, surgery type, and admission hemoglobin level. Final follow-up was completed July 2014 to assess survival through January 31, 2014, and data were analyzed from June 1, 2014, to September 7, 2015. MAIN OUTCOMES AND MEASURES Perioperative AKI, presence of CKD, and overall and cause-specific mortality. RESULTS Among the 3646 patients undergoing vascular surgery, perioperative AKI occurred in 1801 (49.4%) and CKD was present in 496 (13.6%). The top 2 causes among the 1577 deaths in our cohort were cardiovascular disease (845 of 1577 [53.6%]) and cancer (173 of 1577 [11.0%]). Adjusted cardiovascular mortality estimates at 10 years were 17%, 31%, 30%, and 41%, respectively, for patients with no kidney disease, AKI without CKD, CKD without AKI, and AKI with CKD. Adjusted hazard ratios (95% CIs) for cardiovascular mortality were significantly elevated among patients with AKI without CKD (2.07 [1.74-2.45]), CKD without AKI (2.01 [1.46-2.78]), and AKI with CKD (2.99 [2.37-3.78]) and were higher than those for other risk factors, including increasing age (1.03 per 1-year increase; 1.02-1.04), emergent surgery (1.47; 1.27-1.71), and admission hemoglobin levels lower than 10 g/dL (1.39; 1.14-1.69) compared with a hemoglobin level of 12 g/dL or higher. CONCLUSIONS AND RELEVANCE Perioperative AKI is common in patients undergoing vascular surgery and is associated with a high risk for cardiovascular-specific mortality comparable to that seen with CKD. These findings reinforce the importance of preoperative and postoperative risk stratification for kidney disease and the implementation of strategies now available to help prevent perioperative AKI.

Abstract
BACKGROUND Endovascular aortic aneurysm repair (EVAR) is a prophylactic procedure, so the decision to operate should consider, as recent guidelines suggest, the life expectancy of the patient. Several models for predicting life span have been already designed, but little is known about how intervened patients evolve in Southern European Countries, where the incidence of coronary artery disease, the main cause of death among these subjects, is low. METHODS We conducted a retrospective analysis of 176 consecutive patients who underwent elective EVAR at the Vascular Surgery Department of the Hospital del Mar (Barcelona, Spain) during 2000-2014. Cox regressions were performed to identify preoperative factors associated with long-term survival after EVAR, and a risk model was developed. RESULTS Three- and five-year survival rates were 73.9 and 53.9 %, respectively. During the follow-up, 72 deaths (40.9 %) were registered, cancer being the most frequent cause (41.7 %). Preoperative variables negatively associated with long-term survival were serum creatinine ≥ 150 µmol/L (HR 2.5; 95 % CI 1.4-4.2), chronic obstructive pulmonary disease (HR 1.9; 95 % CI 1.2-3.1), atrial fibrillation (HR 2.0; 95 % CI 1.2-3.4), and prior cancer history (HR 1.9; 95 % CI 1.2-3.1). Distal pulses present in both lower limbs were marginally associated with survival (HR 0.65; 95 % CI 0.4-1.07). The survival predictive model showed a good discrimination capacity (C statistic = 0.703; 95 % CI 0.641-0.765). CONCLUSIONS Long-term survival of patients submitted to EVAR in our setting was worse than expected and markedly related to cancer. Our study suggests that predictive models for long-term survival after EVAR may be influenced by regional characteristics of the intervened population. This effect should be taken in consideration in the decision-making process of these patients.

Abstract
OBJECTIVE The targeted vascular module in the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) consists of self-selected hospitals that choose to collect extra clinical details for better risk adjustment and improved procedure-specific outcomes. The purpose of this study was to compare patient selection and outcomes between targeted and nontargeted hospitals in the NSQIP regarding the operative management of abdominal aortic aneurysm (AAA). METHODS We identified all patients who underwent endovascular aneurysm repair (EVAR) or open AAA repair from 2011 to 2013 and compared cases by whether the operation took place in a targeted or nontargeted hospital. EVAR and open repair as well as intact and ruptured aneurysms were evaluated separately. Only variables contained in both modules were used to evaluate rupture status and operation type. All thoracoabdominal aneurysms were excluded. Univariate analysis was performed for intact and ruptured EVAR and open repair grouped by complexity, defined as visceral involvement in open repair and a compilation of concomitant procedures for EVAR. Multivariable models were developed to identify effect of hospital type on mortality. RESULTS There were 17,651 AAA repairs identified. After exclusion of aneurysms involving the thoracic aorta (n = 352), there were 1600 open AAA repairs at targeted hospitals (21% ruptured) and 2725 at nontargeted hospitals (19% ruptured) and 4986 EVARs performed at targeted hospitals (6.7% ruptured) and 7988 at nontargeted hospitals (5.2% ruptured). There was no significant difference in 30-day mortality rates between targeted and nontargeted hospitals for intact aneurysms (EVAR noncomplex, 1.8% vs 1.4% [P = .07]; open repair noncomplex, 4.2% vs 4.5% [P = .7]; EVAR complex, 5.0% vs 3.2% [P = .3]; open repair complex, 8.0% vs 6.0% [P = .2]). For ruptured aneurysms, again there was no difference in mortality between the targeted and nontargeted hospitals (EVAR noncomplex, 23% vs 25% [P = .4]; open repair noncomplex, 38% vs 34% [P = .2]; EVAR complex, 29% vs 33% [P = 1.0]; open repair complex, 27% vs 41% [P = .09]). Multivariable analysis further demonstrated that having an operation at a targeted vs nontargeted hospital had no impact on mortality for both intact and ruptured aneurysms (odds ratio, 1.1 [0.9-1.4] and 1.0 [0.8-1.3], respectively). CONCLUSIONS This analysis highlights the similarities between targeted and nontargeted hospitals within the NSQIP for AAA operative management and suggests that data from the targeted NSQIP, in terms of AAA management, are generalizable to all NSQIP hospitals.

Abstract
Background Studies reporting the influence of preoperative abdominal aortic aneurysm diameter on late survival following abdominal aortic aneurysm repair have not been consistent. Aim: To report the influence of abdominal aortic aneurysm diameter on overall long-term survival following abdominal aortic aneurysm repair. Methods Embase, Medline and the Cochrane electronic databases were searched to identify articles reporting the influence of abdominal aortic aneurysm diameter on late survival following open aneurysm repair and endovascular aneurysm repair published up to April 2015. Data were extracted from multivariate analysis; estimated risks were expressed as hazard ratio. Results A total of 2167 titles/abstracts were retrieved, of which 76 studies were fully assessed; 19 studies reporting on 22,104 patients were included. Preoperative larger abdominal aortic aneurysm size was associated with a worse survival compared to smaller aneurysms with a pooled hazard ratio of 1.14 (95% CI: 1.09–1.18), per 1 cm increase in abdominal aortic aneurysm diameter. Subgroup analysis of the different types of repair was performed and the hazard ratio (95% CI), for open aneurysm repair and endovascular aneurysm repair were 1.08 (1.03–1.12) and 1.20 (1.15–1.25), respectively, per 1 cm increase. There was a significant difference between the groups p < 0.02. Conclusions This meta-analysis suggests that preoperative large abdominal aortic aneurysm independently influences overall late survival following abdominal aortic aneurysm repair, and this association was greater in abdominal aortic aneurysm repaired with endovascular aneurysm repair.

Outcome of visceral chimney grafts after urgent endovascular repair of complex aortic lesions. J Vasc Surg 2016; 63:625-33.

Abstract
OBJECTIVE Endovascular abdominal aortic repair requires an adequate sealing zone. The chimney graft (CG) technique may be the only option for urgent high-risk patients who are unfit for open repair and have no adequate sealing zone. This single-center experience provides long-term results of CGs with endovascular repair for urgent and complex aortic lesions. METHODS Between July 2006 and October 2012, 51 patients (16 women) with a median age of 77 years (interquartile range, 72-81 years), were treated urgently (within 24 hours [61%]) or semiurgently (within 3 days [39%]) with endovascular aortic repair and visceral CGs (n = 73). Median follow-up was 2.3 years (interquartile range, 0.8-5.0 years) for the whole cohort, 3 years for 30-day survivors, and 4.8 years for patients who are still alive. RESULTS Five patients (10%) died within 30 days. All of them had a sacrificed kidney. All-cause mortality was 57% (n = 29), but the chimney- and procedure-related mortality was 6% (n = 3) and 16% (n = 8), respectively. Chimney-related death was due to bleeding, infection, renal failure, and multiple organ failure. There were two postoperative ruptures; both were fatal although not related to the treated disease. The primary and secondary long-term CG patencies were 89% (65 of 73) and 93% (68 of 73), respectively. Primary type I endoleak (EL-I) occurred in 10% (5 of 51) of the patients, and only one patient had recurrent EL-I (2%; 1 of 51). No secondary endoleak was observed. Chimney-related reintervention was required in 16% (8 of 51) of the patients because of EL-I (n = 3), visceral ischemia (n = 4), and bleeding (n = 2). The reinterventions included stenting (n = 5), embolization (n = 3), and laparotomy (n = 2). Thirty-one visceral branches were sacrificed (9 celiac trunks, 9 right, and 13 left renal arteries). Among the 30-day survivors, 8 of 17 patients (47%) with a sacrificed kidney required permanent dialysis; of these, seven underwent an urgent index operation. The aneurysm sac shrank in 63% (29 of 46) of cases. CONCLUSIONS The 6% chimney-related mortality and 93% long-term patency seem promising in urgent, complex aortic lesions of a high-risk population and may justify a continued yet restrictive applicability of this technique. Most endoleaks could be sealed endovascularly. However, sacrifice of a kidney in this elderly cohort was associated with permanent dialysis in 47% of patients.

Abstract
OBJECTIVE Open conversion after endovascular aortic aneurysm repair (EVAR-c) is performed nonelectively in up to 60% of cases. EVAR-c has been reported to have significantly greater risk of postoperative morbidity and mortality than primary aortic repair, but few data exist on outcomes for symptomatic or ruptured presentations. This study determined outcomes and identified predictors of postoperative major adverse cardiac events (MACEs) and mortality for patients undergoing nonelective EVAR-c compared with nonelective primary aortic repair (PAR) in the Vascular Quality Initiative (VQI). METHODS All VQI patients undergoing urgent/emergency EVAR-c or urgent/emergency PAR from 2002 to 2014 were reviewed. Urgent presentation was defined by repair ≤24 hours of a nonelective admission, and emergency operations had clinical or radiographic evidence, or both, of rupture. End points included in-hospital MACE (myocardial infarction, dysrhythmia, congestive heart failure) and 30-day mortality. Possible covariates identified on univariate analysis (P < .2) were entered into a multivariable model, and stepwise elimination identified the best subset of predictors. Generalized estimating equations logistic regression analysis was used to determine the relative effect of EVAR-c compared with PAR on outcomes. RESULTS During the study interval, we identified 277 EVAR-c, and 118 (43%) underwent urgent/emergency repair. nonelective PAR was performed in 1388 of 6152 total (23%). EVAR-c patients were older (75 ± 9 vs 71 ± 10 years; P < .0001), more likely to be male (84% vs 74%; P = .02), and had a higher prevalence of hypertension (88% vs 79%; P = .02) and coronary artery disease (38% vs 27%; P = .01). No differences in MACE (EVAR-c, 31% [n = 34] vs PAR, 30% [n = 398]) or any major postoperative complication (EVAR-c, 57% [n = 63] vs PAR, 55% [n = 740]; P = .8) were found; however, 30-day mortality was significantly greater in EVAR-c (37% [n = 41]) than in (PAR, 24% [n = 291]; P = .003), with an odds ratio (OR) of 2.2 (95% confidence interval [CI], 1.04-4.77; P = .04) for EVAR-c. Predictors of any MACE included age (OR, × 1.03 for each additional year; 95% CI, 1.01-1.03; P = .0002), male gender (OR, 1.3; 95% CI, 1.03-1.67; P = .03), body mass index ≤20 kg/m2 (OR, 1.8; 95% CI, 1.13-2.87; P = .01), chronic obstructive pulmonary disease (OR, 1.2; 95% CI, 0.86-1.80; P = .25), congestive heart failure (OR, 1.5; 95% CI, 0.98-2.34; P = .06), preoperative chronic β-blocker use (OR, 1.3; 95% CI, 0.97-1.63; P = .09), and emergency presentation (OR, 2.3; 95% CI, 1.8-3.01; area under the curve, 0.70; P < .0001). Significant predictors for 30-day mortality were age (OR × 1.07 for each additional year; 95% CI, 1.05-1.09; P < .0001), female gender (OR, 1.6; 95% CI, 1.01-2.46; P = .04), preoperative creatinine >1.8 mg/dL (OR, 1.6; 95% CI, 1.04-2.35; P = .03), an emergency presentation (OR, 4.8; 95% CI, 2.93-7.93; P < .0001), and renal/visceral ischemia (OR, × 1.1 for each unit increase log (time-minutes); 95% CI, 1.02-1.22; area under the curve, 0.84; P = .01). CONCLUSIONS Nonelective EVAR-c patients are older and have higher prevalence of cardiovascular risk factors than PAR patients. Similar rates of postoperative complications occur; however, urgent/emergency EVAR-c has a significantly higher risk of 30-day mortality than nonelective PAR. Several variables are identified that predict outcomes after these repairs and may help risk stratify patients to further inform clinical decision making when patients present nonelectively with EVAR failure.

Abstract
Endovascular aneurysm repair (EVAR) is a minimally invasive method for the treatment of abdominal aortic aneurysms; however, the implementation of this technique is often limited by the aortic pathology, especially in the urgent or emergent setting. An 82-year-old male with a 7.3 cm symptomatic juxtarenal aneurysm presented at our centre for assessment. He was diagnosed as a high-risk candidate for open repair and therefore, not suitable for a conventional EVAR. Fortunately, a custom two-vessel fenestrated stent graft, which was originally constructed for another patient, was available. This device was implanted with no complications and all branches remain unobstructed; clear of aneurysms at 1 year. We present the use of 'in-stock' fenestrated grafts as a potential option to be considered in the urgent or emergent repair of abdominal aortic aneurysms.

Abstract
The treatment of thoracoabdominal aneurysms and juxtarenal aortic aneurysms remains technically challenging, with outcomes primarily dictated by aortic cross-clamp and end-organ ischemia during branch reconstruction. This has remained a challenge for the surgeon regardless of an elective setting or an emergent operation. Here we describe the application of a novel hybrid graft technique for aortic branch reconstruction using rapid, endoluminal anastomoses during open aortic reconstruction.

Abstract
PURPOSE We collected our experience in the use of chimney technique with endovascular aneurysm repair (Ch-EVAR) for juxtarenal aortic aneurysms (JAAs), and reviewed the outcomes. METHODS The patients who were treated with Ch-EVAR between January 2012 and December 2015 were retrospectively reviewed. All of the patients underwent endovascular aneurysm repair (EVAR) under general anesthesia. Femoral arterial access was obtained to place the main body of the endograft; brachial or axillary access was obtained to perform the placement of the chimney stent. RESULTS We treated 12 patients with 15 renal arteries using the Ch-EVAR procedure. Technical success was achieved in 11 of the 12 (91.6%) cases. Within the first 30 days of postoperative period, the target vessel patency rate was 93.3% (14 of 15 renal arteries). After a median follow-up period of 28 months, one patient required Ch-EVAR-related re-intervention due to a type Ia endoleak, and 13 of the 15 renal arteries were patent at the end of the follow-up period. CONCLUSION Our findings demonstrate that Ch-EVAR can be completed with a high rate of success. Although early target vessel occlusion or early postoperative mortality might occur, Ch-EVAR could be an alternative treatment for JAA, especially in high risk patients.

Abstract
OBJECTIVE National data evaluating outcomes for occlusive abdominal aortic reconstructions are well described. The relative effect of operative indication as well as the presence of concomitant abdominal aortic aneurysm (AAA) on in-hospital mortality is not well defined. METHODS The Nationwide Inpatient Sample was queried to identify patients who underwent open aortic surgery (2003-2010). Indication for surgery was classified by International Classification of Diseases, Ninth Revision diagnostic codes to identify isolated occlusive indications as well as combined occlusive disease and AAA. Primary outcome was in-hospital mortality. Secondary outcomes were complications and discharge disposition. RESULTS Overall, 56,374 underwent aortic reconstruction, 48,591 for occlusive disease (86.2%) and 7783 for combined occlusive disease with AAA (13.8%). Intermittent claudication was the most common indication for intervention (60.9%), whereas 39.7% underwent intervention for critical limb ischemia (22.2% rest pain, 17.6% gangrene). Patients with intermittent claudication had more concomitant AAAs (17.3%) than did patients with critical limb ischemia (8.4%). The baseline characteristics for those with occlusive disease and combined occlusive with AAA disease were similar in terms of obesity (4.8% vs 4.2%; P = .27) and congestive heart failure (6.6% vs 6.3%; P = .65) but differed by age (62.2 years vs 68.4 years; P < .0001) and hypertension (65.4% vs 69.1%; P = .005). Patients with combined occlusive and AAA disease had higher mortality than those with occlusive disease alone (3.9% vs 2.7%; P = .01). On multivariable regression, factors associated with in-hospital mortality included gangrene with AAA compared with gangrene alone (odds ratio [OR], 2.8; 95% confidence interval [CI], 1.6-4.7; P < .0002), age >65 years age (OR, 3.1; 95% CI, 2.4-4.1; P < .0001), renal failure (OR, 2.7; 95% CI, 1.9-3.8; P < .0001), and concurrent lower extremity revascularization (OR, 1.3; 95% CI, 1.1-1.7; P < .02). CONCLUSIONS Intermittent claudication or critical limb ischemia with concomitant AAA carries a higher mortality than intermittent claudication or critical limb ischemia alone, especially in older patients with gangrene requiring revascularization and renal insufficiency. Preoperative risk stratification strategies should focus on the indication for surgery as well as the presence of concomitant AAA.
