Percutaneous treatment of traumatic upper-extremity arterial injuries: a single-center experience.

PURPOSE: To assess the feasibility and effectiveness of emergency percutaneous treatment of traumatic injuries of upper-extremity arteries. MATERIALS AND METHODS: Between January 2000 and December 2007, 11 patients (mean age, 49.9 years) with traumatic injuries of upper-extremity arteries were observed: three had pseudoaneurysms, four had dissections, three had transections, and one had mural hematoma. Lesions involved the axillary (n = 6), subclavian (n = 3), or brachial artery (n = 2). Pseudoaneurysms and transections were treated with stent grafts, (n = 6) and dissections and mural hematomas were treated with bare stents (n = 2) or angioplasty (n = 3). Follow-up (mean, 45.1 months; range, 12-84 months) was performed with color Doppler ultrasonography at 1, 3, 6, and 12 months and then, yearly. RESULTS: Immediate technical success was obtained in all cases. No major complications occurred; there was one asymptomatic occlusion of the interosseous artery and one case of incomplete thrombosis of the radial artery (with recanalization after 1 month with systemic medical therapy). During a mean follow-up of 45.1 months, one stent-graft occlusion occurred, which was treated with intraarterial pharmacologic thrombolysis (urokinase 60,000 IU/h for 12 hours). Overall primary clinical success rate was 95.2% and secondary clinical success rate was 100%. CONCLUSIONS: Percutaneous treatment is a feasible and safe tool for injuries of upper-extremity arteries because it can provide a fast and definitive termination of bleeding or a resolution of acute ischemia. This approach, with its low invasiveness, can be proposed as first-line treatment in patients with traumatic lesions of upper-extremity arteries.
