Four cases of the occipital-vertebral anastomosis, demonstrated on vertebral arteriogram, were reported; three on the left side and one on the right side. The occlusion in the vertebral artery at the posterior end of the horizontal segment or the more distal segment of the vertebral artery was found in two cases and no occlusion involving the carotid and vertebral arteries was present in the remaining two cases. The direct type of the occipital-vertebral anastomosis was found in all of the four cases in the atlanto-occipital space. The developmental mechanism of the anastomosis was explained based upon the author's hypothesis on the embryonic development of the occipital artery.
报告了4例经椎动脉造影证实的枕-椎吻合病例；左侧3例，右侧1例。2例在椎动脉水平段后端或椎动脉更远端段存在椎动脉闭塞，其余2例未发现涉及颈内动脉和椎动脉的闭塞情况。所有4例在寰枕间隙均发现枕-椎吻合的直接类型。基于作者对枕动脉胚胎发育的假说，对该吻合的发育机制进行了解释。
