Text of the abstract

Introduction: For patients with infrarenal aortic stenosis (IAS) the following endosurgical treatment options exist: 1. percutaneous transluminal angioplasty (PTA), 2. aortic stenting, and 3. aortobiiliac stenting.
Aim: The aim of this study was to determine the success of IAS interventions.
Method: Fifty-two symptomatic patients (33 females; median age: 60 [56-67] years) with IAS who underwent endovascular treatment between 2001 and 2017 were retrospectively analyzed. Patient, vessel, lesion, and balloon/stent characteristics were examined. Follow-up included peripheral pulse palpation, ankle-brachial index measurement, and Doppler ultrasound examination. Kaplan-Meier analysis was used as statistical method.
Results: The cause of IAS was vasculitis in two patients (4%) and atherosclerosis in 50 (96%). Thirteen percent of the patients were ≤50 years, 73% were smokers, 88% had hypertension, 40% had hyperlipidemia, 33% had diabetes mellitus, 23% were obese (BMI≥30kg/m2), and 8% had chronic kidney disease. The median length of IAS was 17.6 (10.8-27.2) mm, while the grade of IAS was 70 (70-80)%. Severe calcification was present in 19% of the patients. In four cases (8%) PTA, in 34 (65%) aortic stenting, and in 14 (27%) kissing stenting was performed. Two puncture site complications and an aortic rupture requiring surgical repair occurred. The median follow-up time was 63 (18-96) months. The primary patency rate was 100% at 6 months, 96% at 12 and 24 months, and 83% at 60 and 120 months. Restenosis developed in six patients (12%); reintervention was carried out in four cases (8%).
Conclusion: Interventions in patients with IAS can be performed with excellent patency rates.
