Injury to the axillary artery following anterior dislocation of the shoulder

Proximal humerus fractures with associated axillary artery injury

Proximal humerus fractures have rarely been associated with injuries to the axillary artery. Most of the fractures described have been Neer 2-part surgical neck fractures with medialization of the shaft fragment and resultant laceration or thrombosis of the axillary artery. No intraoperative deaths have been reported. We present a series of 3 proximal humerus fractures, 2 of which are Neer 3- to 4-part anterior fracture dislocations, and associated axillary artery injury. There were 2 mortalities, 1 intraoperative. After a thorough review of the English literature, we identified an additional 11 cases of axillary artery injury associated with proximal humerus fracture. The purpose of this study was to heighten the clinical suspicion of this vascular injury in patients with proximal humerus fracture dislocations and surgical neck fractures with shaft medialization, as well as to review pathogenesis and guide management decisions.

[Axillary artery pseudo-aneurysm secondary to shoulder dislocation in children]

Axillary artery injury following anterior dislocation of the shoulder in children is a rare complication often considered as iatrogenic. We report the case of a pseudo-aneurysm of the axillary artery in a 5-year-old boy that appeared four months after a shoulder dislocation that was reduced in an ambulatory setting. Although this is an uncommon vascular complication, we emphasize the need for short-term and long-term follow-up in these children to avoid missing a pseudo-aneurysm of the axillary artery.

Axillary artery transection after shoulder dislocation

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.

Axillary artery transection following anterior shoulder dislocation: classical presentation and current concepts

Injury to the axillary artery following anterior shoulder dislocation is a very rare occurrence. This review serves to illustrate the now classical case of an elderly gentleman with a recurrent dislocation, transection of the axillary artery and its invariable association with a severe brachial plexus lesion, which is the most important determinant of long-term disability. It also highlights the pathognomic triad of anterior shoulder dislocation, expanding axillary haematoma and diminished peripheral pulse, to highlight awareness of this important injury. The literature on this injury has been reviewed and recommendations for the immediate and early post-operative investigation and management have been brought up to date in line with current thinking.

Vascular complications of anterior dislocation of the shoulder

Vascular complications are rare in cases of simple anterior dislocation of the shoulder but the axillary artery and its branches may be damaged. Four cases of axillary artery injury, including 2 cases of complete transection of the artery, are presented. Full upper limb function may return if the vascular damage is recognized and prompt surgical treatment undertaken.

Axillary artery occlusion with erect dislocation of the shoulder

Occlusion of the axillary artery occurred in a man with erect dislocation (luxatio erecta) of the shoulder. This combination of injuries has not previously been reported. The arterial injury was demonstrated by arteriography and repaired by a vein graft. There was an associated fracture of the greater tuberosity of the humerus, which required open reduction and internal fixation.
