Single-Center Retrospective Comparative Analysis of Transradial, Transbrachial, and Transfemoral Approach for Mesenteric Arterial Procedures.

Abstract Purpose To assess feasibility and safety of transradial access (TRA) compared with transfemoral access (TFA) and transbrachial access (TBA) for mesenteric arterial endovascular procedures. Materials and Methods A retrospective cohort analysis was performed including all consecutive patients who underwent a mesenteric arterial procedure in a tertiary referral center between May 2012 and February 2018. Exclusion criteria were absence of data and lost to follow-up within 24 hours after the procedure. During the study period, 103 patients underwent 148 mesenteric arterial procedures (TBA, n = 52; TFA, n = 39; TRA, n = 57). Mean patient age was 64.3 years ± 13.3, and 91 patients (62%) were women. Primary outcomes were vascular access specified technical success rate and access site complication rate, as reported in hospital records. Results Technical success rate specified for the vascular access technique did not differ between the 3 approaches (TBA 96%, TFA 87%, TRA 91%; TRA vs TBA, P = .295; TBA vs TFA, P = .112; TRA vs TFA, P = .524), and overall access site complication rate was not different between the 3 approaches (TBA 42%, TFA 23%, TRA 35%; TRA vs TBA, P = .439; TBA vs TFA, P = .055; TRA vs TFA, P = .208). However, more major access site complications were reported for TBA than for TRA or TFA (TBA 17%, TFA 3%, TRA 2%; TRA vs TBA, P = .005; TBA vs TFA, P = .026; TRA vs TFA, P = .785). Conclusions TRA is a safe and feasible approach for mesenteric arterial procedures comparable to TFA, but with a significantly lower major access site complication rate than TBA.
