We report a thoracic outlet syndrome revealed by neurological complications. Angiography of the subclavian artery depicted an isolated positional occlusion of the descending scapular artery. This side branch of the subclavian artery is anatomically located close to and supplies the brachial plexus. Surgical treatment led to improvement of most symptoms and post-operative control angiography was normal. Not previously described, this sign illustrates the objective compression of the brachial plexus. Ischemia is perhaps intricated with compression, a well-known pathophysiological mechanism of neurological complications in this syndrome. This artery feeding the brachial plexus is usually ligated during surgical neurolysis but must be preserved in order to improve recovery of neurological function and prevent surgical failures.
我们报告了一例因神经并发症而发现的胸廓出口综合征。锁骨下动脉血管造影显示肩胛下动脉降支存在孤立性位置性闭塞。锁骨下动脉的这一分支在解剖学上靠近臂丛神经并为其供血。手术治疗使大多数症状得到改善，术后对照血管造影正常。这种体征此前未被描述过，它说明了臂丛神经受到客观压迫。缺血可能与压迫交织在一起，这是该综合征中神经并发症的一种众所周知的病理生理机制。在手术神经松解过程中，通常会结扎为臂丛神经供血的这条动脉，但为了改善神经功能恢复并防止手术失败，必须予以保留。
