At the point where the vertebral artery crosses the posterior arch of the atlas it may sometimes be enclosed by a bridge of bone, the so-called foramen arcuale. The foramen limits the normal mobility of the vessel during flexion and extension of the neck and may cause disturbances of arterial flow and of the peri-arterial sympathetic plexus giving rise to symptoms similar to those found in the Barre-Lieou syndrome. The authors describes the angiographic findings in such patients and a technique for the surgical excision of the foramen. The results of the operation in two groups of patients, with and without associated spondylosis of the lower cervical spine, are presented.
在椎动脉穿过寰椎后弓处，有时可能被一骨桥包绕，即所谓的弓状孔。该孔在颈部屈伸时限制了血管的正常活动度，可能导致动脉血流及动脉周围交感神经丛紊乱，引发与巴雷 - 利厄综合征相似的症状。作者描述了此类患者的血管造影表现以及一种手术切除该孔的技术。文中呈现了两组患者（伴有和不伴有下颈椎骨质增生）的手术结果。
