Midterm Outcomes after Primary Stenting in Treatment of Atherosclerotic Iliac Arteries

IntroductionThe purpose of this study was to report the midterm outcomes of primary stenting of iliac arteries with additional factors which affect the outcome and to compare the results between patients with simple and complex aorta iliac occlusive disease (AOID).Material and methodsFrom January 2015 and March 2018, the study consisted of 103 lesions in 93 patients with common iliac artery (CIA) and/or external iliac artery (EIA) lesions which accompanied with severe claudication or critical limb ischemia. Balloon-expandable stents (BMS), self-expandable stents (SES) and covered stents (CS) were used to treat the lesions.ResultsLesions of 93 patients that were in CIA and/or EIA and treated with ET were included to the study (n=103). Seventy-one (68.9%) lesions were classified as simple AIOD group (TASCII A-B) while 32(31.1%) were classified as complex AIOD (TASCII C-D) group. In 72.8% of the lesions only mild calcification was detected while 27.2% lesions had moderate or severe calcification. Mean stent diameter for CIA position was 8.26±0.8mm and for EIA position was 7.52±0.8mm. Mean lesion length in patients treated with BMS were 52.5±21.0mm while SES were 63.6±28.3(p=0.03). Technical success was achieved in 101(98.1%) lesions. Significant differences in primary (93% vs 63%) and secondary (98% vs 82%) patency rates at 24 months were found between patients in simple and complex AIOD group (p<0.001 p=0.001)ConclusionsConclusion: In our study, it was found that the primary stenting in patients who had AIOD had satisfactory results with high immediate success, low complication rates and acceptable midterm outcomes.
