Complex upper extremity vascular trauma in an urban population

Eighty patients with upper extremity vascular trauma were treated during a 4-year period. Of 123 vascular injuries, 95 were arterial, 1 was primary venous, and 27 were associated venous injuries. Causes included penetrating (64%), blunt (27%), and iatrogenic injuries (9%). Arteries injured were ulnar (34), radial (28), brachial (22), subclavian (6), and axillary (5). Numbers of patients with associated injuries were nerve (53), vein (27), bone (23), and soft tissue injuries (60). The most common techniques of arterial repair were end-to-end anastomosis (50), followed by interposition saphenous vein grafting (40). Fasciotomy was used in 36 patients. Two arterial repairs failed during surgery and required revision (1) or thrombectomy (1). One radial artery repair thrombosed during late follow-up, with maintenance of normal extremity perfusion via the ulnar artery. No amputations were required, and 83% of all patients treated for nerve injuries resolved or improved their neurologic deficits. Two or more operations for surgical debridement and subsequent wound closure were required in 35 patients. This study supports an aggressive approach to diagnosis and treatment of complex upper extremity vascular trauma emphasizing meticulous surgical technique, liberal use of fasciotomy, and aggressive intraoperative debridement and repair of associated injuries.
