Surgical and Endovascular Management of Penetrating Innominate Artery Injuries

Objective: To review our management of penetrating innominate artery injuries by open and endovascular techniques. Methods: Data regarding patient demography, clinical presentation, investigations, associated injuries, pathology, management, complications and mortality, were collected on patients treated at a single centre over 18 years. Results: 39 innominate artery injuries were treated. There were 36 men and three women, with a mean age of 27 years (range 18-49).Thirty-eight injuries were due to stabwounds and one was the result of a gunshot wound. The most common clinical presentations were shock (47%) and haematoma(42%). Twenty-three patients had associated injuries. The most common pathology was false aneurysm in 21 patients followed by 13 actively bleeding injuries, 4 arteriovenous fistulas and 1 arterial occlusion. Thirty-four patients underwent surgical and five endovascular repair. Overall survival was 79%. The stroke rate for surviving patients was 6%. Patients treated with endovascular stenting had shorter hospital and intensive care unit stays than those treated with surgery. Conclusions: Innominate artery injuries have high rates of morbidity and mortality. A vascular surgical approach with pre-operative angiography, when possible and careful surgical planning by a dedicated team promotes better surgical results. Endovascular and hybrid procedures can become the method of choice when treating stable patients. © 2008 European Society for Vascular Surgery.
