Endovascular Treatment of an Axillary Pseudoaneurysm Following a Traumatic Shoulder Dislocation

A pseudoaneurysm following a shoulder dislocation is considered rare. We report here a case of an 82-yearold man who suffered from vascular and neurological injury due to an axillary pseudoaneurysm following anterior dislocation of the left shoulder. An emerging swelling in the shoulder region was caused by a hematoma and a slowly bleeding pseudoaneurysm in combination with reactive swelling of the soft tissues. Neurological damage occurred due to local compression. A minimally invasive technique was used to treat the pseudoaneurysm. Embolization was initially attempted, but this treatment failed. A stent was subsequently inserted to eliminate the axillary pseudoaneurysm from the circulation. Early imaging and an aggressive endovascular treatment should be considered in all patients suffering from an axillary artery (pseudo)aneurysm.
