目的 探讨通过颈内动脉回流压的测定 ,预测大脑侧支循环的代偿能力。方法 对 6例行颈总动脉结扎或切除的病人术中测量颈内动脉回流压。结果 颈内动脉回流压在 64mmHg(8.8kPa)～ 85mmHg(11.3 3kPa)之间 ,6例术中、术后均无大脑并发症。结论 颈内动脉回流压在一定水平 ,结扎或切除颈总动脉是可行的。
Objective To investigate the compensatory ability of cerebral collateral circulation by measuring the ICA pressure. Methods 6 cases of carotid artery ligation or resection of intraoperative measurement of internal carotid artery pressure. Results The internal carotid artery reflux pressure was between 64mmHg (8.8kPa) ~ 85mmHg (11.3 3kPa). There were no intraoperative and postoperative brain complications in 6 cases. Conclusions The internal carotid artery pressure in a certain level, ligation or removal of the common carotid artery is feasible.
