COMPARATIVE STUDY BETWEEN TRANSBRACHIAL VS TRANSFEMORAL ANGIOPLASTY OF CHRONIC COMPLETE ILIAC ARTERY OCCLUSION

Abstract

Background: Critical limb ischemia (CLI) is the most advanced stage of peripheral arterial occlusive disease; the prognosis is poor, with amputation rates up to 30 % and mortality up to 25% after 1 year. Objective: To compare between transbrachial approach and ipsilateral transfemoral approach either ultrasound guided or road map technique in common iliac artery occlusion angioplasty. Patients and Methods: A retrospective study conducted at the Department of Vascular Surgery, Faculty of Medicine, Al-Azhar University Hospitals from January 2019 till October 2020. The 88 patients who are candidates for study were subdivided into to three groups: Group A: Including 31 patients for whom transbrachial iliac angioplasty, Group B: Including 30 patients for whom transfemoral ultrasound guided iliac angioplasty and Group C: Including 27 patients for whom transfemoral road map guided iliac angioplasty. All lesions were categorized according to the Trans-Atlantic Inter-Society Consensus II (TASC) classification. Results: Transbrachial success rate was 90.32% compared with 96.6 in transfemoral access. No statistical difference was found. Patency rate reached 90.3%, 90.0% and 85.2% in transbrachial, transfemoral ultrasound and transfemoral road map guided groups respectively (X2:0.462; P=0.794). Peri-procedural complication rate reached 16.1%, 6.7% and 74.1% in Tran brachial, transfemoral ultrasound and transfemoral road map guided groups, respectively. Complications were statistically higher significantly in transfemoral road map guided group (X2:0.462; P=0.794). Thirty days mortality rate reached 11.1%, 23.8% and 17.4% in Tran brachial, transfemoral ultrasound and transfemoral road map guided groups, respectively. This was not statistically different among the three access groups (X2: 1.362; P=0.506). Amputation rate reached 9.7%, 6.7% and 3.7% in transbrachial, transfemoral ultrasound and transfemoral road map guided groups, respectively. No statistically significant difference was found (X2: 6.207; P=0.145). Conclusion: The technical success of all approaches is high, with higher success rate in transfemoral access. While we found more bleeding complications with transfemoral access.
