Combined venous and arterial access in the arm for treatment of a complex dural arteriovenous fistula: a technical video.

Abstract

Transvenous access is a necessary tool for numerous cerebrovascular pathologies.Transvenous access in the arm offers several benefits compared with transfemoral access, including patient comfort, the avoidance of transfemoral access complications, and the ability to close both radial arterial access and distal arm venous access with a single transradial compression band.1In this video we describe the indications, technical nuances, benefits, and limitations of transvenous access in the arm.neurintsurg;jnis-2023-020996v1/V1F1V1Video 1- Combined venous and arterial access in the arm for treatment of a complex dural arteriovenous fistulaWe present the case of a young patient who presented with pulsatile tinnitus and was found to have a Cognard type IIa dural arteriovenous fistula near the left transverse sigmoid junction.The patient was treated with transvenous embolization via the distal right basilic vein, and a single radial compression band served to close both the arterial and venous access sites.
