[Surgical treatment of traumatic aneurysm of descending aorta with abnormal right subclavian artery].

Among 11 patients with traumatic aneurysms of the descending thoracic aorta, 2 had developmental anomalies of the branches of the arch of the aorta, in particular, independent origin of the right subclavian artery from the descending thoracic aorta. The anomalous right subclavian artery plays the role of a retaining ligament in trauma, and the forming posttraumatic false aneurysm is localized distal of the ostium of the right subclavian artery. The need for clamping the thoracic aorta and both subclavian arteries for the period of aneurysm reconstruction requires catheterization of the arch of the aorta for arterial pressure control. Surgical correction of aneurysm in anomalous origin of the right subclavian artery has peculiarities of its own in the formation of the proximal anastomosis.
