Objective: Transradial access (TRA) has traditionally been favored for coronary interventions. Tools with up to 200 cm length now allow operators to treat infrainguinal peripheral arterial disease (PAD) using TRA. This study aims to assess the safety and feasibility of TRA infrainguinal interventions. Methods: Patients with infrainguinal PAD who underwent intervention via TRA from July 2013 through June 2019 were retrospectively reviewed. Exclusion criteria included Barbeau D waveform, a radial artery diameter of greater than 2 mm, radial artery occlusion, Raynaud syndrome, or peripheral vasculitis. Procedural success (adequate inline flow to the foot), TRA alone failure (crossover or use of an additional access site), clinical success (defined as improvement in ankle brachial index, clinical symptoms, or wound healing) and adverse events were recorded from procedure notes and follow-up visits. Results: Thirty-six procedures were attempted using TRA in 32 patients (mean age, 65.8 years; range, 29-86; 22 male, 14 female) with mean height of 65.8 inches (range, 59.0-72.0 inches) and a body mass index of 28.7 (range, 19.1-43.9). Preprocedure Rutherford classification (II/III/IV/V/VI) was 8/15/2/7/4, respectively. The left radial artery was used for 35 of 36 procedures (97.2%). Treated vessels included the common femoral (n = 4), superficial femoral (n = 25), deep femoral (n = 1), popliteal (n = 10), tibioperoneal trunk (n = 2), tibial (n = 4), and plantar (n = 1) arteries. Interventions included angioplasty (n = 32, 100%), atherectomy (n = 8, 25%), and stenting (n = 13, 41%). Procedural success was 100%, the TRA alone failure rate was 11.1%, and clinical success was 89.3%. The median follow-up was 286.5 days (range, 0-919 days). Adverse events included radial artery pseudoaneurysm (n = 1), access site hematoma/bleeding (n = 3), radial artery occlusion (n = 1), groin hematoma (n = 1), popliteal artery dissection treated with stenting (n = 2), and a small superficial femoral artery perforation (n = 1) treated with prolonged balloon tamponade. No patients experienced signs of cerebrovascular events or distal embolism. Conclusions: TRA is a useful option for treating patients with PAD; however, several limitations still exist.
