Stingray envenomation is rare but reported to cause severe pain, localized tissue destruction and delayed wound healing with several reports of exsanguination or near exsanguination after insidious localized progressive tissue necrosis and arterial erosion. We report a case of upper extremity stingray envenomation resulting in a laceration to the radial artery and pseudoaneurysm formation. After a positive Allenís test indicating adequate collateral ulnar artery flow to the hand, we chose to ligate the radial artery and perform a wide debridement of the wound to prevent further tissue necrosis and possible exsanguination. In this video, we demonstrate the appropriate preoperative workup and imaging as well as intraoperative technique for radial artery ligation after stingray envenomation.
