Evaluating the Efficacy and Safety of Transbrachial Access in Iliac Endovascular Interventions: A Comprehensive Analysis

Background: This study evaluates the use of transbrachial artery access for endovascular treatment of iliac artery lesions, with a focus on its efficacy and safety outcomes. Methods: Between January 2020 and May 2023, 94 patients with iliac artery disease underwent endovascular procedures via a transbrachial access approach. The majority of patients (n = 68; 72%) presented with lifestyle-limiting claudication (Rutherford category 3). Diagnostic angiography identified Transatlantic Inter-Society Consensus II (TASC) C/D lesions in 54 patients (57%). The primary outcome was achieving technical success with transbrachial access, while secondary outcomes included secondary technical success (necessitating additional transfemoral access), access site complications, and cerebrovascular events. Results: The primary and secondary technical success rates were 82% and 92%, respectively. Access site-related adverse events occurred in 12 patients (12%), primarily hematomas (seven events, 7.4%; two requiring transfusion) and pseudoaneurysms (four events, 4.2%). Thrombotic occlusion was observed in one patient (1%), and brachial arterial bleeding requiring urgent surgical intervention occurred in three patients (3.2%). Neurological complications included two cerebrovascular events (2.1%), although no permanent or transient median nerve injuries were observed. Conclusions: The transbrachial approach represents a potential alternative to the femoral artery route in patients with iliac artery lesions. However, the relatively higher incidence of access site complications may limit its broader application in clinical practice.
