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.
在11例创伤性胸降主动脉瘤患者中，2例存在主动脉弓分支发育异常，特别是右锁骨下动脉独立起源于胸降主动脉。异常的右锁骨下动脉在创伤中起保留韧带的作用，创伤后形成的假性动脉瘤位于右锁骨下动脉开口的远端。在动脉瘤重建期间需要夹闭胸主动脉和双侧锁骨下动脉，这就需要对主动脉弓进行插管以控制动脉血压。右锁骨下动脉异常起源的动脉瘤手术矫正在近端吻合口的形成上有其自身特点。
