Development and Validation of a Novel Preoperative Risk Score to Identify Patients at Risk for Nonhome Discharge after Elective Endovascular Aortic Aneurysm Repair (EVAR). Ann Vasc Surg 2024; 99:341-348. [PMID: 37852368 DOI: 10.1016/j.avsg.2023.08.040] [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: 06/27/2023] [Revised: 08/21/2023] [Accepted: 08/25/2023] [Indexed: 10/20/2023]
Abstract
BACKGROUND Nonhome discharge (NHD) to a rehabilitation or skilled nursing facility after elective endovascular aortic repair (EVAR) is uncommon. However, NHD after surgery has an important impact on patient quality of life and postdischarge outcomes. Understanding factors that put patients undergoing EVAR at high risk for NHD is essential to providing adequate preoperative counseling and shared decision making. This study aimed to identify independent predictors of NHD following elective EVAR and to create a clinically useful preoperative risk score. METHODS Elective EVAR cases were queried from the Society for Vascular Surgery Vascular Quality Initiative 2014-2018. A risk score was created by splitting the data set into two-thirds for development and one-third for validation. A parsimonious stepwise hierarchical multivariable logistic regression controlling for hospital level variation was performed in the development dataset, and the beta-coefficients were used to assign points for a risk score. The score was then validated, and model performance assessed. RESULTS Overall, 24,426 patients were included and 932 (3.8%) required NHD. Multivariable analysis in the development group identified independent predictors of NHD, which were used to create a 20-point risk score. Patients were stratified into 3 groups based upon their risk score: low risk (0-7 points; n = 16,699) with an NHD rate of 1.8%, moderate risk (8-13 points; n = 7,315) with an NHD rate of 7.3%, and high risk (≥14 points; n = 412) with an NHD rate of 21.8%. The risk score had good predictive ability with c-statistic = 0.75 for model development and c-statistic = 0.73 in the validation dataset. CONCLUSIONS This novel risk score can predict NHD following EVAR using characteristics that can be identified preoperatively. Utilization of this score may allow for improved risk assessment, preoperative counseling, and shared decision making.

[PMID: 37068627 DOI: 10.1016/j.avsg.2023.03.034] [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: 02/03/2023] [Revised: 03/28/2023] [Accepted: 03/28/2023] [Indexed: 04/19/2023]
Abstract
BACKGROUND Endovascular abdominal aortic repair (EVAR) is the main therapeutic option for repairing abdominal aortic aneurysms (AAAs). We aimed to determine the long-term outcomes of patients who underwent EVAR at our center. METHODS In this retrospective cohort study, patients who underwent EVAR for intact isolated AAA at Tehran Heart Center between 2007 and 2017 were included. Clinical outcomes and the frequency of mortality were analyzed for follow-up periods. We calculated the 5-year survival rate and its predictors for our patients using Kaplan-Meier estimation. RESULTS We included the data of all patients (154 patients, mean age = 70.7 [± 8.0] years, 96.1% men) who successfully underwent EVAR at our center. The most common risk factors were coronary artery disease (70.1%), hypertension (68.2%), smoking (64.9%), and dyslipidemia (39.6%). There was no mortality during the procedure. The median follow-up was 65.5 months. An average decrease of 9.07 mm (95% confidence interval: 6.9-11.2) occurred in the size of the AAA. During follow-up, 12 patients developed some complications, 49 died, and 7 did not complete the follow-up. The 5-year survival rate was 75% (3.9%). The independent predictors for 5-year survival were age (hazard ratio [HR] = 1.06, P = 0.002) and anemia (HR = 1.91, P = 0.029). Despite not being statistically significant, dyslipidemia (HR = 0.573, P = 0.078) and long intensive care unit/cardiac care unit stays (HR = 1.08, P = 0.070) were borderline mortality predictors. CONCLUSIONS This study depicted an acceptable survival rate for patients who underwent EVAR at our center. Age and anemia, 2 modifiable predictors of 5-year survival, can probably prolong the survival rate of patients, which requires evaluation later.

Incidence, predictors, and prognostic impact of in-hospital serious adverse events in patients ≥75 years of age undergoing elective endovascular aneurysm repair. Surgery 2023; 173:1093-1101. [PMID: 36526489 DOI: 10.1016/j.surg.2022.11.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2022] [Revised: 10/26/2022] [Accepted: 11/13/2022] [Indexed: 12/15/2022]
Abstract
BACKGROUND This study sought to identify the factors associated with the occurrence of in-hospital serious adverse events after elective endovascular aortic repair (EVAR) in older patients within the Global Registry for Endovascular Aortic Treatment. METHODS Consecutive patients ages ≥75 years who received GORE EXCLUDER AAA Endoprosthesis (W.L. Gore & Associates, Inc, Flagstaff, AZ) for elective EVAR. Based on the age at index elective EVAR, patients were categorized into 3 groups for subsequent analyses: those ages 75 to 79, 80 to 84, and ≥85 years. The primary end points for this study were the incidence of serious adverse events and all-cause mortality. In-hospital complications were defined according to the International Organization for Standardization 14155 standard (https://www.iso.org/standard/71690.html) and considered serious adverse events if they led to any of the following: (1) a life-threatening illness or injury, (2) a permanent impairment of a body structure or a body function, (3) in-patient or prolonged hospitalization, or (4) medical or surgical intervention to prevent life-threatening illness or injury or permanent impairment to a body structure or a body function. RESULTS Overall, 1,333 older patients (ages 75-79: n = 601; 80-84: n = 474; and ≥85: n = 258) underwent elective EVAR in the Global Registry for Endovascular Aortic Treatment data set and were included in the present analysis. In total, 12 patients (0.9%) died perioperatively, and 103 patients (7.7%) experienced ≥1 in-hospital serious adverse event, with 18 patients (1.3%) experiencing >1 in-hospital complications. No significant differences were seen between the age groups in the rates of in-hospital serious adverse events (7.3% vs 8.2% vs 7.8%; P = .86). In logistic regression analysis, a history of chronic obstructive pulmonary disease (odds ratio = 2.014; 95% confidence interval, 1.215-3.340; P = .006) and prior requirement for dialysis (odds ratio = 4.655; 95% confidence interval, 1.087-19.928; P = .038) resulted as predictors for occurrence of in-hospital serious adverse events. In the whole cohort, the 5-year survival was 63% for patients who did not experience any in-hospital serious adverse events compared with 51% for those who experienced any complications (P = .003). Using multivariable Cox proportional hazards models, it was found that the occurrence of in-hospital serious adverse events (hazard ratio = 6.2; 95% confidence interval, 1.8-21.317; P = .003) and being underweight (hazard ratio = 7.0; 95% confidence interval, 1.371-35.783; P = .019) were the only independent predictors of death in ≤30 days from the initial intervention. Although age did not independently affect the risk for all-cause mortality in ≤180 days after the initial intervention, increasing age was associated with a higher risk for long-term death (ie, ≥181 days from index elective EVAR) in the multivariable analysis (ages 75-79: hazard ratio = 0.379; 95% confidence interval, 0.281-0.512; P < .001; and 80-84: hazard ratio = 0.562; 95% confidence interval, 0.419-0.754; P < .001). CONCLUSION After elective EVAR in older patients (ie, ≥75 years), the occurrence of in-hospital serious adverse events appears to increase the risk of death, particularly in ≤180 days after the initial elective EVAR intervention, and might be related to patient baseline characteristics, including history of pulmonary and renal disease.

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.

Outcomes of Octogenarians with Primary Malignant Cardiac Tumors: National Cancer Database Analysis. J Clin Med 2022; 11:jcm11164899. [PMID: 36013139 PMCID: PMC9410046 DOI: 10.3390/jcm11164899] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2022] [Revised: 08/09/2022] [Accepted: 08/17/2022] [Indexed: 11/16/2022] Open
Abstract
Data concerning age-related populations affected with primary malignant cardiac tumors (PMCTs) are still scarce. The aim of the current study was to analyze mortality differences amongst different age groups of patients with PMCTs, as reported by the National Cancer Database (NCDB). The NCDB was retrospectively reviewed for PMCTs from 2004 to 2017. The primary outcome was late mortality differences amongst different age categories (octogenarian, septuagenarian, younger age), while secondary outcomes included differences in treatment patterns and perioperative (30-day) mortality. A total of 736 patients were included, including 72 (9.8%) septuagenarians and 44 (5.98%) octogenarians. Angiosarcoma was the most prevalent PMCT. Surgery was performed in 432 (58.7%) patients (60.3%, 55.6%, and 40.9% in younger age, septuagenarian, and octogenarian, respectively, p = 0.04), with a corresponding 30-day mortality of 9.0% (7.0, 15.0, and 38.9% respectively, p < 0.001) and a median overall survival of 15.7 months (18.1, 8.7, and 4.5 months respectively). Using multivariable Cox regression, independent predictors of late mortality included octogenarian, governmental insurance, CDCC grade II/III, earlier year of diagnosis, angiosarcoma, stage III/IV, and absence of surgery/chemotherapy. With increasing age, patients presented a more significant comorbidity burden compared to younger ones and were treated more conservatively. Early and late survival outcomes progressively declined with advanced age.

Abstract
OBJECTIVE The long-term survival differences between endovascular and open repair for abdominal aortic aneurysms and specifically the impact of age on these differences remain a topic of debate. Therefore, we compared the long-term mortality between endovascular and open abdominal aneurysm repair for patients of different ages. METHODS This was a retrospective cohort study of prospectively collected data from patients undergoing elective endovascular or open repair for infrarenal abdominal aortic aneurysms within the Vascular Quality Initiative multi-national clinical registry (2003-2021). The primary outcome was long-term all-cause mortality comparing endovascular and open repair for patients aged <65 years, between 65-79 years, and those aged ≥80. In addition, we investigated the interaction between repair modality and ten-year hazard of mortality for sex, aneurysm diameter, and several pre-operative comorbid conditions within each age category. To account for non-random assignment of treatment, we used propensity scores and inverse probability weighted Cox proportional hazard analysis. RESULTS We identified 48,074 patients undergoing elective infrarenal abdominal aneurysm repair (89% endovascular) within the study period, including 7,940 patients aged <65, 29,555 aged between 65-79, and 10,579 aged ≥80 years. EVAR was associated with a higher propensity score-adjusted long-term hazard of mortality compared to open repair in the cohort aged <65 years (hazard ratio [HR]: 1.39; 95% confidence interval [CI]: 1.04-1.86; P=.026). The mortality was similar in the age cohort between 65-79 (HR: 0.94; 95%CI: 0.79-1.10; P=.43), while EVAR was associated with a lower hazard of mortality in the cohort aged ≥80 years (HR: 0.63; 95%CI: 0.46-0.86; P=.004). In patients aged <65, the hazard of mortality was higher with endovascular compared with open repair in those with female sex (HR: 4.40; 95%CI: 1.75-11.0), an aneurysm diameter >65mm (HR: 2.19; 95%CI: 1.11-4.34), and absence of coronary artery disease (HR: 1.26; 95%CI: 0.83-1.91), congestive heart failure (HR: 1.41; 95%CI: 1.03-1.92), and renal dysfunction (HR: 1.46; 95%CI: 1.04-2.05). In the patient cohort aged ≥80, a lower hazard of mortality for endovascular vs. open repair was observed for male patients, or those with small aneurysms or certain comorbidities. CONCLUSIONS In a selected group of young patients with a substantial life expectancy, the long-term mortality is higher with endovascular compared to open repair for infrarenal abdominal aortic aneurysms. Long-term mortality with endovascular repair is similar in the middle cohort and lower in the elderly cohort compared to open repair.

Abstract
OBJECTIVE To investigate the association between hospital volume and failure to rescue (FtR), after open (OAR) and endovascular (EVAR) repair of intact abdominal aortic aneurysms (AAA) among centers participating in the VASCUNET and International Consortium of Vascular Registries (ICVR). SUMMARY BACKGROUND DATA FtR (i.e., in-hospital death following major complications) is a composite end-point representing the inability to treat complications effectively and prevent death. METHODS Using data from eight vascular registries, complication and mortality rates after intact AAA repair were examined (n = 60,273; EVAR-43,668; OAR-16,605). A restricted analysis using pooled data from four countries (Australia, Hungary, New Zealand, USA) reporting data on all postoperative complications (bleeding, stroke, cardiac, respiratory, renal, colonic ischemia) was performed to identify risk-adjusted association between hospital volume and FtR. RESULTS The most frequently reported complications were cardiac (EVAR-3.0%, OAR-8.9%) and respiratory (EVAR-1.0%, OAR-5.7%). In adjusted analysis, 4.3% of EVARs and 18.5% of OARs had at least one complication. The overall FtR rate was 10.3% after EVAR and 15.7% after OAR. Subjects treated in the highest volume centers(Q4) had 46% and 80% lower odds of FtR after EVAR (OR = 0.54; 95%CI = 0.34-0.87;p = 0.04) and OAR (OR = 0.22; 95%CI = 0.11-0.44;p < 0.001) when compared to lowest volume centers(Q1), respectively. Colonic ischemia had the highest risk of FtR for both procedures (adjusted predicted risks, EVAR: 27%, 95%CI 14%-45%; OAR: 30%, 95%CI 17%-46%). CONCLUSIONS In this multi-national dataset, FtR rate after intact AAA repair with EVAR and OAR is significantly associated with hospital volume. Hospitals in the top volume quartiles achieve the lowest mortality after a complication has occurred.

J Vasc Surg 2020; 73:1549-1556. [PMID: 33065243 DOI: 10.1016/j.jvs.2020.10.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2020] [Accepted: 10/01/2020] [Indexed: 10/23/2022]
Abstract
BACKGROUND Nonhome discharge (NHD) to a rehabilitation or skilled nursing facility after vascular surgery is poorly described despite its large impact on patients. Understanding postsurgical NHD risk is essential to providing adequate preoperative counseling and shared decision making, particularly for elective surgeries. We aimed to identify independent predictors of NHD after elective thoracic endovascular aortic repair (TEVAR) for thoracic aortic aneurysms (TAA) and to create a clinically useful preoperative risk score. METHODS Elective TEVAR cases for descending TAA were queried from the Society for Vascular Surgery Vascular Quality Initiative from 2014 to 2018. A risk score was created by splitting the dataset into two-thirds for model development and one-third for validation. A parsimonious stepwise hierarchical multivariable logistic regression controlling for hospital level variation was performed in the development dataset, and the beta-coefficients were used to assign points for a risk score. This score was then cross-validated and model performance assessed. RESULTS Overall, 1469 patients were included and 213 (14.5%) required NHD. At baseline, patients who required NHD were more likely to be ≥80 years old (35.2% vs 19.4%), female (58.7% vs 40.6%), functionally dependent (42.3% vs 24.0%), and anemic (46.5% vs 27.8%), and to have chronic obstructive pulmonary disease (41.3% vs 33.4%), congestive heart failure (18.8% vs 11.1%), and American Society of Anesthesiologists class ≥4 (51.6% vs 39.8%; all P < .05). Multivariable analysis in the development group identified independent predictors of NHD that were used to create an 18-point risk score. Patients were stratified into three groups based upon their risk score: low risk (0-7 points; n = 563) with an NHD rate of 4.3%, moderate risk (8-11 points; n = 701) with an NHD rate of 17.0%, and high risk (≥12 points; n = 205) with an NHD rate of 34.2%. The risk score had good predictive ability with a c-statistic of 0.75 for model development and a c-statistic of 0.72 in the validation dataset. CONCLUSIONS This novel risk score can predict NHD after TEVAR for TAA using characteristics that can be identified preoperatively. The use of this score may allow for improved risk assessment, preoperative counseling, and shared decision making.

J Vasc Surg 2020; 73:1253-1260. [PMID: 32889076 DOI: 10.1016/j.jvs.2020.08.033] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2020] [Accepted: 08/04/2020] [Indexed: 12/17/2022]
Abstract
BACKGROUND Access issues are one of the most common complications of endovascular aneurysm repair (EVAR). However, contemporary rates as well as risk factors for complications and the subsequent impact of access complications on mortality are poorly described. METHODS We studied all EVAR for intact abdominal aortic aneurysms without prior aortic surgery in the Vascular Quality Initiative between 2011 and 2018. We studied factors associated with access complications (thrombosis, embolus, wound infection, hematoma, and conversion to cutdown), as well as the interaction with female sex and the impact on survival using multilevel logistic regression and propensity weighting. Multiple imputation was used for missing data. RESULTS There were 33,951 EVAR during the study period (91% elective, 9% symptomatic); most cases (70%) involved an attempt at percutaneous access on at least one side, with 30% bilateral cutdowns and 0.1% iliac conduits. There were 1553 patients (4.6%) who experienced at least one access complication. Access complications were almost twice as common in female patients (7.5% vs 3.9%; P < .001). The factors associated with access complications included female sex (odds ratio [OR], 2.7; 95% confidence interval [CI], 2.0-3.6; P < .001), age (OR, 1.05 per 5 years; 95% CI, 1.02-1.1; P < .01), aortouni-iliac device (OR, 1.6; 95% CI, 1.1-2.3; P < .01), smoking (OR, 1.4; 95% CI, 1.1-1.7; P < .01), body mass index of less than 16 (OR, 1.8; 95% CI, 1.3-2.5; P = .001), dual antiplatelet therapy (1.3; 95% CI, 1.02-1.6 P = .03), prior infrainguinal bypass (OR, 1.8; 95% CI, 1.3-2.7; P < .01), and beta blocker use (OR, 1.2; 95% CI, 1.03-1.4; P = .02). Conversion from percutaneous access to open cutdown was associated with higher rates of complications than planned open cutdown (8.6% vs 2.9%; P < .001). In propensity-weighted analysis, percutaneous access was associated with significantly lower odds of access complications in women (OR, 0.6; 95% CI, 0.4-0.96; P = .03). Patients who experienced an access complication had more than four times the odds of perioperative death (OR, 4.2; 95% CI, 2.5-7.1; P < .001), and a 60% higher risk of long-term mortality (hazard ratio, 1.6; 95% CI, 1.2-2.1; P = .001). In addition to death, patients with access site complications had higher rates of other major complications, including reoperation during the index hospitalization (19% vs 1.2%; P < .001), myocardial infarction (3.5% vs 0.7%; P < .001), stroke (0.8% vs 0.2%; P < .001), acute kidney injury (12% vs 3%; P < .001), and reintubation (5.7% vs 0.8%). CONCLUSIONS Although access complications are infrequent in the current era, they are associated with both perioperative and long-term morbidity and mortality. Female patients in particular are at high risk of access complications, but may benefit from percutaneous access.
