Dural Arteriovenous Fistula Treated with Transvenous Embolization via the Upper Limb Cutaneous Vein.

Objective: In recent years, the transradial artery approach has gained prominence and is increasingly employed in neurovascular angiography and therapy due to its safety, reduced complications, and minimal invasiveness. While various venous approaches, including the conventional transfemoral vein approach, exist for procedures such as transvenous embolization, recent reports have highlighted methods involving upper extremity cutaneous veins. However, the practicality and efficacy of these approaches remain unclear.

Case presentations: This study presents our experience with three cases of dural arteriovenous fistulas, where transvenous embolization was performed via upper limb cutaneous veins. In all instances, the arteriovenous approach was successfully executed using a single upper extremity, leading to the successful completion of treatment.

Conclusion: This technique demonstrates significant advantages, not only in terms of its minimal invasiveness but also due to its simplicity and safety. Anticipating broader acceptance in the future, this approach offers a promising avenue for further exploration in neurovascular interventions.
