摘要
用冰冻连续切片、显微镜、接目测微镜观察测量14具年龄＞50岁的新鲜颈椎标本，结果显示，钩突增生占21.43％，椎动脉在横突孔内侧占57.86％，椎动脉与脊神经间距＜1mm者占97.14％，左推动脉横径男女有显著差异；横突孔内壁无增生，横突孔半孔率7．14％，99.29％的椎动脉C6横突孔上升。表明钩突后外侧的增生、推动脉在横突孔的位置、横突孔的半孔变异及椎动脉横径窄小，可影响椎动脉血流量脊神经与椎动脉间距较小，椎动脉受压同时可影响脊神经。
During 1991 － 93 the observation of the cervical vertebral artery and its surrounding structure were completed by meansof the frozen section, operating microscopic view and eyepiece micrometer in the cervical vertebral of 14 adult fresh cadavers. One thousand four hundred and seventy availabIe paranleters were obtained. The hyperplasia of the uncinate proceeswas 21 .43 %. The cervical vertebral artery located in medial of the transverse foramen was 57. 86%. The distance betweenthe cervical vertebral artery and the cervical spine cord ramus (97. 14% ) was less than lcm. The hyperplasia of the uncinale process in posterior － lateral and the situation of the cervical vertebral artery in transverse foramen might affect theblood flow of the cervical vertebral artery. When the cervical vertebral artery was squeezed the cervical spine cord ramusmight be affected also. The microsurgy and measurement of the local anatomical structure of the cervical spines in adultfresh wet cadavers were provided with objectivity.reliability and less deviation. The result possessed similar analomicallycharacteristics of normal human body. This study has an important value in clinic of cervical spondylosis.
