摘要
为探讨椎动脉重建术的远期疗效，用２３只成年杂种犬制成椎动脉闭塞模型，实施椎动脉颈总动脉端侧吻合重建椎动脉，用定量方法监测术后３个月（远期）疗效。结果表明，术后远期全数字化Ｘ线血管造影仪显示椎动脉吻合口保持通畅，侧支循环已逐步建立；彩色多普勒超声显像仪测得椎动脉内血流的动力保持良好，供血量稳定；氢清除法测得局部小脑血流量较术后５分钟（近期）进一步提高１５．８６％；核磁共振仪示在椎动脉供血区无梗塞灶。认为，椎动脉重建术的远期疗效良好。
Occlusive disease of first segment of vertebral artery is the common cause for insufficient supply of vertebro basilar artery. The good result following reconstruction of vertebral artery was confirmed, but the long term result was not certain. In order to investigate the long term result, 23 dogs with established model of VA occlusion were studied. The occlusion was reconstructed by a by pass operation between the common carotid artery and VA, then the quantitative methods were used to monitor the results for 3 months following operation. The results showed that ①according to DSA, the anastomosis remained potent and the collateral circulations were established; ②the hemodynamics of blood flow in VA kept well and the blood supply was stable by color ultrasonic Doppler; ③the blood supply of cerebellum was increased 15.86% compared with that observed just after operation by hydrogen clearance method; and ④ no infarction focus was founded from MRI. The conclusion was that the result suggested that the long term result demonstrated was satisfactory after VA reconstruction for occlusive disease and the blood supply of the cerebellum was also better than that just following operation.
