Acute Upper Limb Ischemia Due to Delayed Presentation of a Brachial Artery Pseudoaneurysm Post-Venipuncture

Brachial artery pseudoaneurysms (BAPs) are rare but could lead to complications of high morbidity. We report a case of a BAP presenting with hand ischemia and median nerve neuropathy nearly a decade after the inciting iatrogenic trauma, successfully treated with excision and direct repair. This report highlights that untreated pseudoaneurysms can be indolent and present late with both symptoms of embolization and local compression.
