作者通过对44例颅外-颅内血管吻合术后患者临床资料的回顾性分析,指出手术效果不应以桥支通畅性而应以桥支血流状况来评价。桥支血流灌注效果可由术前检查资料分析预测。术前软脑膜血管侧支循环发达且局部血流量对乙酰唑胺激发反应差的患者,术后有希望获得血流灌注的明显改善。 资料 年龄40岁～73岁,男38例,女6例。手术 The authors retrospectively analyzed the clinical data of 44 patients with extracranial-intracranial vascular anastomosis, and pointed out that the operative effect should not be evaluated by the branch-flow status. Bridge branch blood perfusion effect can be preoperative examination data analysis and prediction. Preoperative pia mater vascular collateral circulation developed and partial blood flow in patients with poor response to acetazolamide in patients with postoperative hope of significant improvement of perfusion. Data age 40 years old to 73 years old, 38 males and 6 females. surgery
