A Rare Anatomic Variant of the Superficial Palmar Branch of the Radial Artery Used for Arteriovenous Fistula Creation

Abstract

Anatomical knowledge regarding the variant branching patterns of the radial artery is considerably crucial for interventionalists, vascular, and plastic surgeons. We report a case of a rare variant branching pattern where the superficial palmar branch of the radial artery originated from the radial artery in the forearm instead of the wrist with a subcutaneous course in a 52-year-old patient with diabetic end-stage kidney disease who required haemodialysis initiation. This variant branch was used as inflow for the creation of the arteriovenous fistula for haemodialysis access.
