Successful Surgical Resection of Iatrogenic Antecubital Venous Pseudoaneurysm Following Venipuncture: A 2-Case Report.

Iatrogenic venous pseudoaneurysm (VP) formation after venipuncture is rare. This report showed 2 cases of VP following venipuncture, and VPs were resected surgically. A 58-year-old woman and a 56-year-old woman developed a soft antecubital mass after blood sampling from the basilic veins. One patient had the sensory disturbance of forearm. The mass was diagnosed as a VP with thrombus by duplex ultrasound and magnetic resonance imaging. The aneurysm was resected completely, and the sensory disturbance of the patient was improved. Surgical resection was the most appropriate treatment for the relief of symptoms due to compression.
