Cephalic Vein Aneurysm of the Wrist Adjacent to the Superficial Radial Nerve: A Case Report

Venous aneurysms of the upper extremities are uncommon and may be traumatic, iatrogenic, or idiopathic. Herein, we report the case of a 72-year-old female with a cephalic venous aneurysm of the wrist that was closely associated with the superficial radial nerve. To minimize the risk of nerve injury, tangential aneurysmectomy with lateral venorrhaphy was performed. However, early postoperative occlusion occurred despite preserved collateral venous flow, and no neurological deficits were observed. This case highlights the importance of meticulous identification and preservation of adjacent nerves and suggests that vein-preserving repair may have limited durability in superficial venous aneurysms. When adequate collateral circulation is present, aneurysmectomy with ligation may be a safer and more practical option after careful identification and preservation of the superficial radial nerve.
