Utility of Flow Diverter Placement with a Transradial Approach

Abstract

Endovascular treatment with the transradial approach (TRA) has become the standard treatment modality in the cardiovascular field because of its advantages; however, treatment with the transfemoral approach (TFA) in the head and neck field remains insufficient. Flow diverter (FD) placement, which requires the guidance of a relatively large catheter, is usually not performed with TRA; however, it has advantages, such as fewer complications at the puncture site and no restrictions on postoperative rest. Because of its advantages, the TRA is the first choice for FD placement in our hospital. This study retrospectively reviewed FD placement performed using the TRA at our hospital. In total, 24 cases of FD placement using the TRA performed at our hospital from November 2022 to December 2023 were included in the study. Of the 24 cases, FD placement with TRA was successful in 23. The single unsuccessful case involved a guiding catheter, and the procedure was completed using the TFA. No complications were observed at the puncture site, and other perioperative complications were similar to those observed in the general endovascular treatment of cerebrovascular disease. Considering the requirement for antiplatelet drugs, anticoagulants, and other agents in the perioperative period, aggressive TRA should be considered.
