Iliac Artery Endoconduits Should be the Preferred Adjunctive Access Procedure to Facilitate Complex Endovascular Aortic Aneurysm Repair. | LitMetric

AI Article Synopsis

  • * It included 27 patients with 42 conduits at the University of Colorado Hospital from 2009 to 2019, highlighting that the majority were female and average age was 72 years, while focusing on postoperative complications and mortality.
  • * Results showed that 43% of conduits were endovascular and 57% were open, with endovascular conduits leading to significantly fewer complications, although 15% of patients died within 30 days of the procedures.

Article Abstract

Background: Iliac artery anatomy can have a dramatic impact on the success of endovascular complex aortic aneurysm (CAA) procedures as endograft delivery systems need to be advanced and manipulated through these access vessels. The aim of this study was to evaluate the outcomes of iliac artery conduits with emphasizes on open vs endovascular conduits performed to facilitate CAA endovascular repair.

Methods: All patients who had open or endovascular iliac conduits prior to endovascular CAA repair to treat thoracoabdominal, juxtarenal, or suprarenal aneurysms at the University of Colorado Hospital from January 2009 through January 2019 were included. Patients who presented with symptomatic or ruptured aortic aneurysms were excluded. Outcomes of interest included postoperative complications and mortality in patients undergoing iliac conduits.

Results: Twenty-seven patients with a total of 42 conduits were included in the study. The majority of patients ( = 15, 56%) were female and the average age was 72 ± 9 years. The calculated VQI cardiac index was .6% (range, .3%-.8%). Eighteen (43%) endovascular and 24 (57%) open iliac conduits were performed during the study period. Thirty (71%) conduits were performed in a staged fashion, while 12 (29%) were performed at the same time as endovascular CAA repair. The mean time between conduit and definitive aneurysm repair surgery was 130 ± 68 days in the endovascular and 107 ± 79 days in the open groups ( = .87). No aneurysm rupture occurred during the staging period in either group. The median follow-up for the entire cohort was 18 ± 22 months. The median length of hospital stay for patients undergoing endovascular and open ICs was 6 (ranging, 1-28 days) and 7 days (ranging, 3-18 days), respectively. Patients undergoing open conduits had significantly more complications than those undergoing endovascular conduit (endoconduit) creation. A total of 4 (15%) patients died within 30 days after aneurysm repair. Out of 23 survivors, 18 (78%) patients were discharged home, 4 (18%) patients were discharged to a skilled nursing facility, and 1 (4%) patient was discharged to an acute rehabilitation facility. No mortality difference based on type of conduit was found.

Conclusions: Overall complication rate associated with creation of open iliac artery conduits is not negligible. Endoconduits, which carry less morbidity than open conduits, are preferred as a first-line adjunctive access procedure to facilitate complex endovascular aortic aneurysm repair.
