Factors associated with outcome of endovascular treatment of iliac occlusive disease: a single-center experience

Abstract

Background Endovascular treatment (ET) of iliac occlusive disease (IOD) is well established in literature. Use of stents in IOD has achieved long-term limb salvage and patency rates similar to those of open surgery, with lower morbidity and mortality rates. Objectives To report the long-term outcomes, particularly limb salvage and patency rates, of ET for IOD and the factors associated with these outcomes. Methods This retrospective cohort study included patients with IOD who underwent iliac angioplasty (IA), between January 2009 and January 2015. Patients with critical limb ischemia or incapacitating claudication were included. Results In total, 48 IA procedures were performed in 46 patients, with an initial technical success rate of 95.83%. Failure occurred in two patients, who were excluded, leaving 44 patients and 46 IA. The primary patency, secondary patency, limb salvage, and survival rates at 1200 days were 88%, 95.3%, 86.3%, and 69.9%, respectively. Univariate and multivariate Cox regression revealed that the primary patency rate was significantly worse in patients with TASC type C/D than in patients with TASC type A/B (p = 0.044). Analysis of factors associated with major amputation using Cox regression showed that the rate of limb loss was greater in patients with TASC type C/D (p = 0.043). Male gender was associated with reduced survival (p = 0.011). Conclusions TASC type C/D was associated with a higher number of reinterventions and with worse limb loss and primary patency rates. Male gender was associated with a worse survival rate after ET of IOD.

“…Notably, these mortality rates were lower compared to those reported in related studies. Specifically, studies by Kasemi et al and Soares et al, which both examined the outcomes of iliac artery interventions, reported higher mortality rates of 4.5% and 4.3% respectively ( 27 , 28 ).…”
