Abstract

Aim of work: To study the outcomes in patients with occlusive aortoiliac disease treated by covered stents.
Patients and methods: We performed retrospective analysis of prospectively collected data from 23 patients
(28 limbs) with symptomatic aortoiliac disease during the period from January 2016 to October 2019. at Ain
Shams University hospitals. We excluded patients with ulcer or gangrene; aortic lesions not extending to iliacs;
previous aortoiliac interventions; acute ischemia of lower extremity, ectasia or aneurysm of iliacs and/or aorta,
Extensive common femoral artery disease or need for concomitant groin procedures, contraindication to aspirin
or clopidogrel usage, occluded superficial and profunda femoral arteries. We used the Rutherford categories to
characterize the patients at time of treatment with stenting and to compare their clinical and functional outcome
over the follow-up period.
Results: There were 13 males and 10 females, with ages ranging between 37-76 (mean= 59.1 ± 11.4) years. All
patients had symptomatic aortoiliac arterial disease (Rutherford class 2,3,4). Patients were treated with balloon
expandable covered stent and had a median follow-up of 32 months. The mean ABI was 0.52 (± 0.11) at the
start of the study with a significant increase to 0.76 (± 0.12) at 3-year. At the 3-year follow-up, primary patency
was 84.6%, assisted primary patency 92.3%, and secondary patency 96.2%. There were no instances of stent
fracture.
Conclusions: Treating aortoiliac occlusive disease with a covered stent is an excellent choice. The technique has
good patency rate and few complications. More randomized clinical trials are needed to enrich the guidelines.
