Technical Consideration of Endovascular Treatment for Aortoiliac Occlusive Disease Based on a 10-Year Tertiary Hospital Experience: A Retrospective Study.

Purpose To examine the technical considerations of endovascular treatment for aortoiliac occlusive disease (AIOD) based on a 10-year experience in Songklanagarind Hospital. Materials and Methods This retrospective cohort study included 210 patients who underwent endovascular treatment for symptomatic AIOD between January 2010 and December 2020. The patients' clinical and lesion characteristics, including technical considerations of the procedure, were collected, analyzed, and stratified using the Transatlantic Inter-Society Consensus (TASC). Results Most patients (80%) in this study had chronic limb-threatening ischemia lesions, with an occlusion rate of 37%. The technical success rate of TASC C & D was lower than that of TASC A & B, 84.4% vs. 99.2% p ≤ 0.001. A technical success rate of 93.3% (14/15) was found for the femoral and brachial approach, compared with a success rate of 89.0% (57/64) for the unibifemoral approach in TASC C & D, without a statistically significant difference (p = 0.076). However, the puncture site complications in this route were up to 17.6%, which is the highest rate compared with other techniques. These complications could be treated either conservatively or minimally invasively. Conclusion In cases of failed femoral access, simultaneous femoral and brachial approaches improved the technical success rate of endovascular recanalization of TASC C & D aortoiliac occlusions.
