Abstract
BACKGROUND Endovascular aortic repair (EVAR) is an established and attractive alternative to open surgical repair (OSR) of abdominal aortic aneurysms (AAA) due to its superior short-term safety profile. However, opinions are divided regarding its long-term cost-effectiveness. We compared the total yearly cost of running endovascular and OSR services in a single tertiary center to determine whether fenestrated EVAR (FEVAR) represents a clinically efficacious, affordable treatment option. METHODS A single-center retrospective review was performed on 109 patients undergoing a procedure related to index or previous abdominal aortic repair, with 1 year follow-up. Data was collected from the National Vascular Registry and hospital records. The primary outcome was cost per quality-adjusted life year. Secondary outcomes included 30-day mortality and morbidity, reintervention rates, length of hospital stay, aneurysm, and all-cause mortality at 1 year for elective index procedures. RESULTS The average cost per patient of all FEVAR was £16,041.53 (±8,857.54), £13,893.51 (±£21,425.25) for standard EVAR, and £15,357.22 (±£15,904.49) for OSR (FEVAR versus EVAR P = 0.55, FEVAR versus OSR P = 0.83, OSR versus EVAR P = 0.76). Of the secondary outcomes, significant findings included increased length of stay and respiratory morbidity for patients undergoing open versus endovascular repair. There was no significant difference in 30-day or 1-year mortality between groups. CONCLUSIONS FEVAR, EVAR, and OSR all represent cost-effective options for aortic repair with similar outcomes. Our data highlights the potential for FEVAR to present a viable alternative to open repair, particularly in higher-risk groups, when performed in specialist centers.

Abstract
INTRODUCTION With the increasing life expectancy of Western populations, more octogenarians are presenting with large abdominal aortic aneurysm (AAA). Endovascular repair offers a less invasive alternative and older patients who may not have been offered open repair in the past are now being considered for elective repair with this approach. Age in isolation may not be the only consideration in recommending elective aneurysm repair. We aimed to review the literature on complex endovascular AAA repairs (mainly fenestrated endovascular aortic repair [FEVAR]) in octogenarians. METHODS A literature search was conducted using the Ovid Medline®, Embase® and Cochrane Library databases for articles published up to January 2022. All English language publications from 1995 onwards were eligible for inclusion. Search terms included: "FEVAR", "F-EVAR", "fenestrated EVAR", "fenestrated endovascular aortic repair", "fenestrated endovascular aneurysm repair", "fenestrated AAA repair", "fenestrated endograft", "fenestrated stent graft", "fenestrated", "endograft", "EVAR", "octogenarian", "elderly", "above 80" and "over 80". METHODS The literature search identified 134 potential articles. Following qualitative assessment by two independent appraisers, this was refined to 11 studies, in accordance with the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) statement. RESULTS The primary outcome measure was 30-day mortality, which was highly variable, ranging from 0% to 9% in octogenarians and from 0% to 5% in non-octogenarians. However, these differences were only found to be statistically significant in two studies. The secondary outcome measures included technical success rates, major adverse events, reintervention rates, freedom from reintervention, target vessel patency, freedom from target branch instability, and length of hospital and intensive care unit stay. No statistically significant differences were found between octogenarians and non-octogenarians. Long-term survival was significantly lower for octogenarians in two studies. CONCLUSIONS The perioperative outcomes of FEVAR in octogenarians are comparable with those of younger patients. FEVAR therefore appears to be an acceptable option for complex endovascular aneurysm repairs in carefully selected octogenarians. Nevertheless, this review highlights the paucity of published data on the outcomes of endovascular repair of complex aneurysms in octogenarians.

Abstract
BACKGROUND Misinterpretation of patient preferences in perioperative education can lead to an undesired treatment decision. This explorative interview study presents differences in perspectives of patients and professionals on patient education in complex endovascular aortic aneurysm management. METHODS Using convenience sampling, a cross-sectional interview study was performed among patients who were in various stages of the decision-making process for complex endovascular aortic repair. Five physicians were interviewed, representing the main providers of clinical information. Interviews were transcribed verbatim and analyzed inductively. RESULTS Twelve patients (mean age 76.6 [standard deviation: 6.4], 83% male) were interviewed. Ten (83%) felt like they had no other realistic option besides undergoing surgery, whereas all professionals (5/5) stressed the importance of delicate patient selection. Five patients out of 10 (50%) who commented on their preferred decisional role considered the professional's advice as decisive. All but 1 patient (11/12) reported that the information was easy to understand, whereas 4 out of 5 professionals (80%) doubted whether patients could fully comprehend everything. Patients experienced a lack of information on the recovery process, although professionals stated that this was addressed during consultation. CONCLUSIONS Several differences were found in the perspectives of patients and professionals on education in complex aortic aneurysm management. In order to optimize patient involvement in decision-making, professionals should be aware of these possible discrepancies and address them during consultation. Future research could focus on these differences in more detail by including more patients depending on their treatment and decision stages.

[PMID: 37586562 PMCID: PMC10956480 DOI: 10.1016/j.avsg.2023.07.102] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2023] [Revised: 07/19/2023] [Accepted: 07/31/2023] [Indexed: 08/18/2023]
Abstract
BACKGROUND Fenestrated endovascular aneurysm repair (FEVAR) is a well-established treatment approach for juxtarenal and short-neck infrarenal aortic aneurysms. Recommendations and clinical outcomes are lacking for offering FEVAR in patients with chronic kidney disease (CKD). We aimed to compare short- and long-term outcomes for patients with none-to-mild versus moderate-to-severe CKD undergoing FEVAR. METHODS We retrospectively reviewed consecutive patients undergoing standard FEVAR with Cook devices at a single institution. The cohort was stratified by preoperative CKD stage none-to-mild or moderate-to-severe (CKD 1-2 and CKD 3-5, respectively). The primary outcome was postoperative acute kidney injury (AKI). Secondary outcomes included 30-day perioperative complications, 1- and 5-year rates of overall survival, dialysis, renal target artery patency, endoleak, and reintervention assessed by the Kaplan-Meier method. Aneurysm sac regression, number of surveillance computed tomography (CT) scans, and CKD stage progression were assessed at latest follow-up. Multivariate Cox proportional hazards modeling was used to evaluate the association of CKD stage 3 and stage 4-5 with all-cause mortality, controlling for differences in baseline characteristics. RESULTS From 2012- to 2022, 184 patients (of which 82% were male) underwent FEVAR with the Cook ZFEN device (mean follow-up 34.3 months). Group CKD 3-5 comprised 77 patients (42%), was older (75.2 vs. 73.0 years, P = 0.04), had increased preoperative creatinine (1.6 vs. 0.9 mg/dL, P < 0.01), and demonstrated increased renal artery ostial calcification (37.7% vs. 21.5%, P = 0.02) compared with Group CKD 1-2. Perioperatively, CKD 3-5 sustained higher estimated blood loss (342 vs. 228 ml, P = 0.01), longer operative times (186 vs. 162 min, P = 0.04), and longer length of stay (3 vs. 2 days, P < 0.01). Kaplan-Meier 1- and 5-year survival estimates were lower for CKD 3-5 (82.3% vs. 95.1%, P < 0.01 and 55.4% vs. 70.8%, P = 0.02). Fewer CKD 3-5 patients remained free from chronic dialysis at 1 year (94.4% vs. 100%, P = 0.015) and 5 years (84.7% vs. 100%, P < 0.01). There were no significant differences in postoperative AKI rate (CKD 1-2 6.5% vs. CKD 3-5 14.3%, P = 0.13), long-term renal artery patency, reinterventions, type I or III endoleak, mean sac regression, or total follow-up CT scans between groups. CKD stage progression occurred in 47 patients (31%) at latest follow-up but did not differ between stratified groups (P = 0.17). On multivariable modeling, age (hazard ratio 1.05, 95% confidence interval 1.01-1.09, P = 0.02) and CKD stage 4-5 (hazard ratio 6.39, 95% confidence interval 2.26-18.05, P < 0.01) were independently associated with mortality. CONCLUSIONS Preoperative CKD status did not negatively impact the durability or technical success related to aneurysm outcomes after FEVAR. Worsening CKD stage was associated with lower 1- and 5-year overall survival and freedom from dialysis after FEVAR with no statistically significant differences in 30-day or long-term technical aneurysm outcomes.

Outcomes in octogenarians after thoracoabdominal and juxtarenal aortic aneurysm repair using fenestrated-branched devices justifies treatment. J Vasc Surg 2023; 77:694-703.e3. [PMID: 36441071 DOI: 10.1016/j.jvs.2022.10.028] [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: 07/07/2022] [Revised: 10/13/2022] [Accepted: 10/17/2022] [Indexed: 11/06/2022]
Abstract
OBJECTIVE To compare outcomes between octogenarians and nonoctogenarians undergoing thoracoabdominal aortic aneurysm repair and juxtarenal aortic aneurysm repair using branched and/or fenestrated endovascular devices (F/BEVAR) and compare octogenarian survival to population survival statistics from Ontario, Canada. METHODS Patients who underwent F/BEVAR at a single institution between 2007 and 2020 were retrospectively reviewed with a median follow-up of 3.3 years (interquartile range, 1.6-5.3). The median survival of an average 84-year-old Ontarian from Canada, adjusted for a male:female ratio of 4:1, was retrieved from publicly available Statistics Canada data. RESULTS In total, 68 octogenarians (25.8%) and 196 nonoctogenarians (74.2%) were included (mean age, 83.5 ± 3.0 vs 71.9 ± 5.8 years; P ≤ .001). The maximum aneurysm size was significantly larger in octogenarians (68.9 ± 11.4 mm vs 65.4 ± 10.0 mm; P = .017). No differences in the number of thoracoabdominal aortic aneurysm repairs (29.4% vs 38.3%; P = .19) or operative technical success (92.6% vs 85.7%; P = .136) were observed between the two cohorts. Postoperatively, no significant differences in overall in-hospital mortality (7.3% vs 5.1%; P = .49), elective in-hospital mortality (6.1% vs 4.4%; P = .49), stroke (1.5% vs 3.6%; P = .384), or spinal cord ischemia (2.9% vs 9.2%; P = .094) were seen between octogenarians and nonoctogenarians. There was no difference in survival at 4 years between the two cohorts (62.9% vs 71.1%; P = .22), however, survival at 6 years was significantly lower for octogenarians (44.5% vs 64.1%; hazard ratio, 1.96; P = .02). The cumulative rate of reintervention (44.1% vs 41.3%; P = .84) and freedom from branch instability (67.6% vs 73.5%; P = .33) at 6 years were not different between the two groups. When comparing octogenarians who survived to discharge from index hospitalization after F/BEVAR with 84-year-old Ontarians unmatched for comorbidities, a survival difference of 4.8% and 11.1% was noted at 4 and 6 years, respectively. CONCLUSIONS F/BEVAR in octogenarians is associated with no differences in technical success or postoperative adverse outcomes when compared with their younger counterparts. Octogenarians had increased mortality after 4 years and their survival at 4 years was comparable with that of an 84-year-old Ontarian. F/BEVAR was safe and effective in octogenarians deemed fit for intervention. Further research into preoperative patient selection and improving perioperative outcomes is needed.

Abstract
BACKGROUND When introducing new techniques, attention must be paid to learning curve. Besides quantitative outcomes, qualitative factors of influence should be taken into consideration. This retrospective cohort study describes the quantitative learning curve of complex endovascular aortic repair (EVAR) in a nonhigh-volume academic center and provides qualitative factors that were perceived as contributors to this learning curve. With these factors, we aim to aid in future implementation of new techniques. METHODS All patients undergoing complex EVAR in the Leiden University Medical Center (LUMC) between July 2013 and April 2021 were included (n = 90). Quantitative outcomes were as follows: operating time, blood loss, volume of contrast, hospital stay, major adverse events (MAE), 30-day mortality, and complexity. Patients were divided into 3 temporal groups (n = 30) for dichotomous outcomes. Regression plots were used for continuous outcomes. In 2017, the treatment team was interviewed by an external researcher. These interviews were reanalyzed for factors that contributed to successful implementation. RESULTS Length of hospital stay (P = 0.008) and operating time (P = 0.010) decreased significantly over time. Fewer cardiac complications occurred in the third group (3: 0% vs. 2: 17% vs. 1: 17%, P = 0.042). There was a trend of increasing complexity (P = 0.076) and number of fenestrations (P = 0.060). No significant changes occurred in MAE and 30-day mortality. Qualitative factors that, according to the interviewees, positively influenced the learning curve were as follows: communication, mutual trust, a shared sense of responsibility and collective goals, clear authoritative structures, mutual learning, and team capabilities. CONCLUSIONS In addition to factors previously identified in the literature, new learning curve factors were found (mutual learning and shared goals in the operating room (OR)) that should be taken into account when implementing new techniques.

Abstract
Sarcopenia is characterised by chronically reduced skeletal muscle volume and function, and is determined radiologically by psoas and skeletal muscle measurement. The present systematic review and meta-analysis aims to examine the relationship between pre-operative CT-derived psoas and skeletal muscle parameters and outcomes in patients undergoing EVAR and F/B-EVAR for aortic aneurysm. The MEDLINE database was interrogated for studies investigating the effect of pre-operative CT-diagnosed sarcopenia on outcomes following EVAR and F/B-EVAR. The systematic review was carried out in accordance with PRISMA guidelines. The primary outcome was overall mortality. RevMan 5.4.1 was used to perform meta-analysis. PROSPERO Database Registration Number: CRD42021273085. Ten relevant studies were identified, one reporting skeletal muscle parameters, and the remaining nine reporting psoas muscle parameters, which were used for meta-analysis. There were a total of 2563 patients included (2062 EVAR, 501 F/B-EVAR), with mean follow-up ranging from 25 to 101 months. 836 patients (33%) were defined as radiologically sarcopenic. In all studies, the combined HR for all-cause mortality in sarcopenic versus non-sarcopenic patients was 2.61 (1.67–4.08), p < .001. Two studies reported outcomes on patients undergoing F/B-EVAR; the combined HR for all-cause mortality in sarcopenic versus non-sarcopenic patients was 3.08 (1.66–5.71), p = .004. Radiological sarcopenia defined by psoas or skeletal muscle parameters was associated with inferior survival in patients undergoing both EVAR and F/B-EVAR. Current evidence is limited by heterogeneity in assessment of body composition and lack of a consensus definition of radiological sarcopenia.

Abstract
OBJECTIVE We evaluate nationwide perioperative outcomes of complex EVAR and assess the volume-outcome association of complex EVAR. SUMMARY OF BACKGROUND DATA Endovascular treatment with fenestrated (FEVAR) or branched (BEVAR) endografts is progressively used for excluding complex aortic aneurysms (complex AAs). It is unclear if a volume-outcome association exists in endovascular treatment of complex AAs (complex EVAR). METHODS All patients prospectively registered in the Dutch Surgical Aneurysm Audit who underwent complex EVAR (FEVAR or BEVAR) between January 2016 and January 2020 were included. The effect of annual hospital volume on perioperative mortality was examined using multivariable logistic regression analyses. Patients were stratified into quartiles based on annual hospital volume to determine hospital volume categories. RESULTS We included 694 patients (539 FEVAR patients, 155 BEVAR patients). Perioperative mortality following FEVAR was 4.5% and 5.2% following BEVAR. Postoperative complication rates were 30.1% and 48.7%, respectively. The first quartile hospitals performed <9 procedures/yr; second, third, and fourth quartile hospitals performed 9-12, 13-22, and ≥23 procedures/yr. The highest volume hospitals treated the significantly more complex patients. Perioperative mortality of complex EVAR was 9.1% in hospitals with a volume of < 9, and 2.5% in hospitals with a volume of ≥13 (P = 0.008). After adjustment for confounders, an annual volume of ≥13 was associated with less perioperative mortality compared to hospitals with a volume of < 9. CONCLUSIONS Data from this nationwide mandatory quality registry shows a significant effect of hospital volume on perioperative mortality following complex EVAR, with high volume complex EVAR centers demonstrating lower mortality rates.

Abstract
Purpose Complex endovascular aortic repair (EVAR) procedures provide a treatment option for patients with aortic aneurysms involving visceral branches. Good technical results and short-term outcomes have been reported. Whether complex EVAR provides acceptable functional outcomes is not clear. The current study aims to describe postoperative functional outcomes in complex EVAR patients—an older and relatively frail patient group. Materials and Methods A single-center retrospective cohort study was performed, using data from a computerized database of consecutive patients who underwent complex EVAR in the Leiden University Medical Center (LUMC, The Netherlands) between July 2013 and September 2020. As of May 2017, patients scheduled for complex EVAR were referred to a geriatric care pathway to determine (Instrumental) Activities of Daily Living ((I)ADL) scores at baseline and, if informed consent was given, after 12 months. For the total patient group, adverse functional performance outcomes were: discharge to a nursing home and 12-month mortality. For the patients included in geriatric follow-up, the additional outcome was the incidence of functional decline (defined by a ≥2 point increase in (I)ADL-score) at 12-month follow-up Results Eighty-two patients underwent complex EVAR, of which 68 (82.9%) were male. Mean age was 73.3 years (SD=6.3). Within 30 days postsurgery, 6 patients (7.3%) died. Mortality within 12 months for the total patient group was 14.6% (n=12). After surgery, no patients had to be discharged to a nursing home. Fifteen patients (18.3%) were discharged to a rehabilitation center. Twenty-three patients gave informed consent and were included in geriatric follow-up. Five patients (21.7%) presented functional decline 12 months postsurgery and 4 patients had died (17.4%) by that time. This means that 39.1% of the patients in the care pathway suffered an adverse outcome. Conclusion To our knowledge, this is the only study that examined functional performance after complex EVAR, using a prospectively maintained database. No patients were newly discharged to a nursing home and functional performance results at 12 months are promising. Future multidisciplinary research should focus on determining which patients are most prone to deterioration of function, so that efforts can be directed toward preventing postoperative functional decline.

Open surgical repair of juxtarenal abdominal aortic aneurysms in the elderly is not associated with increased thirty-day mortality compared with fenestrated endovascular grafting. J Vasc Surg 2020; 73:1139-1147. [PMID: 32919026 DOI: 10.1016/j.jvs.2020.08.121] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2020] [Accepted: 08/04/2020] [Indexed: 11/17/2022]
Abstract
OBJECTIVE Endovascular repair of juxtarenal abdominal aortic aneurysms (JAAAs) with fenestrated grafts (fenestrated endovascular aneurysm repair [FEVAR]) has been reported to decrease operative mortality and morbidity compared with open surgical repair (OSR). However, previous comparisons of OSR and FEVAR have not necessarily included patients with comparable clinical profiles and aneurysm extent. Although FEVAR has often been chosen as the first-line therapy for high-risk patients such as the elderly, many patients will not have anatomy favorable for FEVAR. At present, a paucity of data has examined the operative outcomes of OSR in elderly patients for JAAAs relative to FEVAR. Therefore, we chose to perform a propensity-matched comparison of OSR and FEVAR for JAAA repair in patients aged ≥70 years. METHODS Patients aged ≥70 years who had undergone elective nonruptured JAAA repairs from 2012 to 2018 were identified in the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) targeted endovascular aneurysm repair (EVAR) and AAA databases. Patients who had undergone FEVAR were identified in the targeted EVAR database as those who had received the Cook Zenith Fenestrated endograft (Cook Medical, Bloomington, Ind). Because our study specifically examined JAAAs, those patients who had undergone OSR with supraceliac proximal clamping or concomitant renal/visceral revascularization were excluded. A 1:1 propensity-match algorithm matched the OSR and FEVAR patients by preoperative clinical and demographic characteristics, operative indications, and aneurysm extent. The 30-day outcomes, including mortality, major adverse cardiovascular events, and pulmonary and renal complications, were compared between the propensity-matched OSR and FEVAR groups. RESULTS A 1:1 propensity match was achieved, and the final analysis included 136 OSR patients and 136 FEVAR patients. No significant differences were found in 30-day mortality (4.4% vs 3.7%; odds ratio [OR], 1.21; 95% confidence interval [CI], 0.36-4.06; P = .759) between the OSR and FEVAR groups. OSR was associated with a higher incidence of major adverse cardiovascular events compared with FEVAR; however, the trend was not statistically significant (8.1% vs 3.7%; OR, 2.31; 95% CI, 0.78-6.82; P = .131). Compared with FEVAR, the OSR group had significantly greater rates of pulmonary complications (19.1% vs 3.7%; OR, 6.19; 95% CI, 2.30-16.67; P < .001) and renal complications (8.1% vs 2.2%; OR, 3.90; 95% CI, 1.06-14.31; P = .040). CONCLUSIONS In the samples assessed in the present study, the results with OSR of JAAAs in the elderly did not differ from those of FEVAR with respect to 30-day mortality despite a greater incidence of pulmonary and renal complications. Although FEVAR should remain the first-line therapy for JAAAs in elderly patients, OSR might be an acceptable alternative for select patients with anatomy unfavorable for FEVAR.

Ann Vasc Surg 2020; 67:52-58. [PMID: 32234393 DOI: 10.1016/j.avsg.2020.03.034] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2020] [Revised: 03/11/2020] [Accepted: 03/13/2020] [Indexed: 11/16/2022]
Abstract
BACKGROUND Fenestrated and branched endovascular aneurysm repair endograft (f/bEVAR) allows the endovascular repair of thoracoabdominal and juxtarenal and pararenal abdominal aortic aneurysms (T-J-P-AAAs); however, given their high cost and complexity, their use should be limited to patients with life expectancy >2 years. Nevertheless, the number of patients older than 80 years treated by f/bEVAR is growing, with no hard evidence of the real efficacy in this context. The aim of the present study is to analyze the survival of ≥80-year-old patients treated with f/bEVAR, and to identify possible predictors of late mortality. METHODS An analysis of clinical, anatomical, and technical characteristics of patients treated with f/bEVAR for J-, P-, and T-AAA from 2010 to 2019 in a single academic center was performed. Follow-up data were collected prospectively with clinical visit and computed tomography angiography at discharge, after 6 months, and yearly thereafter. Survival after 2 years was evaluated by Kaplan-Meier analysis. Possible predictors of mortality were evaluated by univariable/multivariable analysis. RESULTS In the study period, a total of 243 f/bEVARs were considered: 83 for TAAA (34%) and 160 for J/PAAA (66%). Mean age was 73 ± 6 years, with 35 (14%) patients ≥80 years old; 209 patients (86%) were male and 78 (39%) had an American Society of Anesthesiology score IV. The 30-day and 2-year survival were 96% and 80 ± 3%, respectively. At a mean follow-up of 36 ± 25 months, independent predictors of late mortality by Cox regression analysis were chronic obstructive pulmonary disease (COPD), chronic renal failure (CRF), and ≥80 years old (hazard ratio [HR] 1.8, 95% confidence interval [CI] 1.02-3.2, P = 0.05; HR 1.7, 95% CI 1.01-3.4, P = 0.04; HR 3.1, 95% CI 1.5-6.3, P = 0.002, respectively). Preoperative clinical characteristics were similar in ≥80 years old versus younger patients, except for the prevalence of TAAA (14% vs. 38%, P = 0.04). The technical success and 30-day mortality were similar in ≥80 vs. <80-year-old patients (93% vs. 96%, P = 0.31; 7% vs. 3.5%, P = 0.60, respectively). The 2-year survival estimation was significantly lower in ≥80 years old compared with younger patients (62 ± 10% vs. 82 ± 3%, P = 0.003). The association of COPD and CRF significantly affects the 2-year survival in ≥80-year-old patients (no patients survived at 2 years) and was significantly different compared with the survival in ≥80-year-old patients without these risk factors (70 ± 11%, P = 0.001). CONCLUSIONS The early mortality rate and the 2-year survival after f/bEVAR justify this type of treatment in patients ≥80 years old; however, the presence of comorbidities such as COPD and CRF significantly reduces mid-term survival in this group and should be taken into consideration in the indication to f/bEVAR.

Abstract
Background:
Complex endovascular repair of abdominal aortic aneurysm carries higher perioperative
morbidity than standard infrarenal endovascular repair.
Objective:
This study reviews the incidence and associated factors of acute kidney injury in complex aortic endovascular
repair of juxtarenal, pararenal, and thoracoabdominal aortic aneurysms.
Methods:
A literature review was performed for all studies on the endovascular repair of juxtarenal, pararenal,
and thoracoabdominal aneurysms that evaluated rates of acute kidney injury as an outcome. Outcomes were further
analyzed by the level of anatomic complexity and method of repair.
Results:
52 studies met inclusion criteria, with a total of 5454 individuals undergoing repair from 2004 to 2017.
The overall rate of acute kidney injury ranged widely from 0 to 41%, with a rate of hemodialysis from 0 to 19%
(temporary) and 0 to 14% (permanent). Increasing anatomic complexity was associated with higher rates of acute
kidney injury. Mode of endovascular repair, learning curve effect, and preoperative chronic renal insufficiency
did not demonstrate any associations with the outcome.
Conclusion:
Published rates of acute kidney injury in complex aortic aneurysm repair vary widely with few definitively
associated factors other than increasing anatomic complexity and operative time. Further study is
needed for the identification of predictors related to postoperative acute kidney injury.
