Arterial injury of the axilla: an unusual case after blunt trauma of the shoulder.

The lesion of an axillary artery after a shoulder dislocation without bone fractures is very rare. The most common lesion is the subtotal transection of the vessel. Vascular injuries may be associated with nervous lesions whose incidence ranges from 27 to 44%. The nervous lesions are highly invalidating. The symptoms which recur most frequently are motor and sensitive deficiencies and a distal ischemia which, in some cases, may not be noted owing to the extensive collateral network. Whenever these symptoms are covered or absent, as in this case report, an angiography of the upper limb becomes essential for correct diagnosis and treatment.
