Background: There are limited data on access type when treating ruptured abdominal aortic aneurysms (AAAs) with endovascular aneurysm repair (EVAR). Our study's objective was to evaluate if the type of access in ruptured AAAs affected outcomes.
Methods: The Vascular Quality Initiative was queried from 2009 to 2018 for all ruptured AAAs treated with an index EVAR. Procedures were grouped by access type: percutaneous, open, and failed percutaneous that converted to open access. Patients with iliac access, both percutaneous and open access, and concurrent bypass were excluded. Baseline characteristics, procedure details, and outcomes were collected. Univariable and multivariable analyses were performed.
Results: There were 1,206 ruptured AAAs identified-739 (61.3%) was performed by percutaneous access, 416 (34.5%) by open access, and 51 (4.2%) by failed percutaneous that converted to open access. Percutaneous access, compared with open access and failed percutaneous access, respectively, had the shortest operative time (min, median) (111 vs. 138 vs. 180, P < 0.001) and was most often performed under local anesthesia (16.7% vs. 5% vs. 9.8%, P < 0.001). The amount of contrast used was similar between the approaches. Univariable analysis comparing percutaneous access, open access, and failed percutaneous access showed differences in 30-day mortality (19.9% vs. 24.8% vs. 39.2%, P = 0.002), postoperative complications (33.7% vs. 40.2% vs. 54%, P = 0.003), and cardiac complications (18.2% vs. 19.8% vs. 34.7%, P = 0.018). However, multivariable analysis did not show access type to have a significant effect on cardiac complications, pulmonary complications, any complications, return to the operating room, or perioperative mortality. Open access was independently associated with a prolonged length of stay (means ratio 1.17, 95% confidence interval (CI) 1.04-1.33, P = 0.012). Factors independently associated with failed percutaneous were prior bypass (odds ratio (OR) 9.77, 95% CI 2.44-39.16, P = 0.001) and altered mental status (OR 2.45, 95% CI 1.17-5.15, P = 0.018).
Conclusions: Access type for ruptured AAAs was not independently associated with major morbidity or mortality but did have a differential effect on length of stay. Access during these emergent procedures should be based on surgeon preference and experience.
