Aneurysm Diameter

Background: Guidelines from the Society for Vascular Surgery recommend elective repair in asymptomatic patients with an abdominal aortic aneurysm (AAA) only if their diameter is greater than or equal to 5.5 cm, yet smaller ones are routinely repaired. This study aims to evaluate perioperative outcomes based on aneurysm size at the time of repair. Methods: Male patients who underwent elective endovascular aneurysm repair (EVAR) or open abdominal aneurysm repair (OAAR) repair of an infrarenal AAA were abstracted from 2011 to 2015 Targeted National Surgical Quality Improvement Program (NSQIP) database. Patients with symptoms or with aneurysmal extension into the visceral or iliac vessels were excluded. Outcomes of open versus endovascular repair were reported, with multivariate analyses to identify factors associated with the decision to repair AAA ≤5.4 cm. Results: A total of 2115 (90.9%) patients underwent EVAR, while 213 (9.1%) underwent OAAR. The mean diameter in patients who underwent OAAR was 6.1 cm (interquartile range [IQR]: 5.2-6.1 cm) versus 5.7 cm (IQR: 5.2-6.0 cm) for EVAR. However, in 42.5% of EVAR and 32.8% of OAAR patients, the diameter of the AAA was 5.4 cm or less. The group undergoing repair of AAA ≤5.4 cm was younger compared to the larger AAA group (71.9 vs 73.9 years; P < .0001). Patients older than 80 years were less likely to have a repair of AAA measuring ≤5.4 cm (odds ratio [OR] = 0.45, 95% confidence interval [CI] = 0.30-0.65). Additionally, patients who underwent EVAR were more likely to have AAA measuring ≤5.4 cm repaired compared to those who underwent OAAR (OR = 1.62, 95% CI = 1.19-2.21). There were no differences in perioperative morbidity or mortality between the groups. Conclusion: There were no differences in perioperative outcomes after AAA repair, independent of aneurysm diameter. We found a higher likelihood of repairing AAA ≤5.4 cm in younger patients who were more likely to have been repaired with EVAR. Patients older than 80 years were less likely to undergo small AAA repair.

Late Survival

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.

Purpose: A systematic review of all patients that have been reported in the literature with abdominal aortic aneurysm (AAA) concomitant with horseshoe kidney (HSK) treated electively by endovascular aneurysm repair (EVAR) is presented. A new grouping system for describing HSK vasculature is implemented. Materials and Methods: We searched for published manuscripts using the Medical Subject Headings terms “abdominal aortic aneurysm,” “AAA,” “EVAR,” “endovascular aneurysm repair,” and “horseshoe kidney” in PubMed, Google Scholar, Scopus, and National Center for Biotechnology Information databases. Inclusion criteria include all published material of patients with AAA with HSK treated electively by an endovascular approach. We excluded patients who were treated by a hybrid or open repair or patients with ruptured AAA. Statistical analysis was carried out using SPSS Statistics version 25 (IBM Corp, Armonk, New York) software. Results: A total of 50 patients from 30 studies were included for analysis. Males made up 88% (n=44) of the population. The median age for this cohort was 70 years (range: 47–86 years). Median aneurysmal diameter was 6.0 cm (range: 4.0–10.3 cm). The median operative time for endovascular repair was 84 minutes (range: 40–332 minutes). The most common graft used was Zenith, used in 40% (n=20) of the cases, followed by Endurant in 14% (n=7). The overall complication rate was 14% (n=7). The median follow-up was 19 months (range: 1–108 months). While comorbidities did not appear to impact outcomes significantly, median operative times for smokers were higher than those in nonsmokers, 84 versus 118 minutes, respectively (p=0.048). Univariate linear regression modeling of aneurysmal size with age, operative time, and length of stay revealed a significant coefficient association between aneurysmal size and operative times. After adjusting for comorbidities and aneurysmal size, prior history of chronic kidney disease significantly increased odds for renal infarction. Conclusion: This review presents the most complete data set possible of patients with concomitant HSK and AAA treated by an endovascular approach. Furthermore, the A + B + C classification for grouping the HSK vasculature is implemented. This systematic review suggests EVAR to be an excellent option with low complication rates for the treatment of AAA in patients with HSK.
