Axillary artery transection after shoulder dislocation

Abstract

Axillary artery transection after shoulder dislocation without bone fracture is extremely rare. Early diagnosis, use of the occlusion balloon for proximal control of axillary artery bleeding, and surgical treatment are important to avoid morbidity and mortality. A 74-year old man presented with a complete transection of axillary artery associated with anterior dislocation of the shoulder without bone fracture. Left axillary artery transection was seen on angiography. An angioplasty balloon was used to prevent bleeding from the subclavian artery. The brachial plexus was compressed by a hematoma. Axillary artery repair was performed with an autologous reversed saphenous vein graft interposition. The patient had palpable distal pulses postoperatively. Motor function was significantly improved but still impaired in the postoperative period. Follow-up at 3 months showed good function of the left arm.Successful management of axillary artery injuries requires prompt diagnosis and surgical treatment. Neurologic injury may affect the functional outcome of the limb.
