The 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 aortoiliac occlusive disease (AIOD).

Material and methods:
The study took place from January 2015 to March 2018 and included 103 lesions in 93 patients with common iliac artery (CIA) and/or external iliac artery (EIA) lesions 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.

Lesions of 93 patients that were in the CIA and/or EIA and treated with ET were included in the study (n = 103). Seventy-one (68.9%) lesions were classified in the simple AIOD group (TASC II A-B) while 32 (31.1%) were classified in the complex AIOD (TASC II C-D) group. In 72.8% of the lesions only mild calcification was detected while 27.2% of lesions had moderate or severe calcification. Mean stent diameter for CIA position was 8.26 ±0.8 mm and for EIA position was 7.52 ±0.8 mm. Mean lesion length in patients treated with BMS was 52.5 ±21.0 mm while in SES it was 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 groups (p < 0.001, p = 0.001).

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.
