目的探讨不同球囊闭塞试验(BOT)判断标准的可靠性以及减少并发症的策略。方法对86例脑血管病患者进行了BOT,并分析其中38例行动脉闭塞治疗患者的预后。结果常规BOT方法阳性率为10.47%(9/86),阴性率为89.53%(77/86);联合交叉充盈试验的阳性率为36.05%(31/86),阴性率为63.95%(55/86)。动脉闭塞治疗后脑缺血发生率为8.33%(3/36)。技术性并发症发生率为3.49%(3/86)。结论(1)目前BOT能提供基本准确的评估结果。(2)交叉充盈试验和降压试验能有效提高BOT的特异度。(3)将传统方法与新影像技术相结合,寻找客观、定量的指标作为判断标准是今后BOT改进的方向。
Objective To investigate the reliability of different criteria of balloon occlusion test (BOT) and to reduce the complications. Methods Eighty-six patients with cerebrovascular disease underwent BOT and the prognosis of 38 patients undergoing arterial occlusion was analyzed. Results The positive rate of conventional BOT was 10.47% (9/86) and the negative rate was 89.53% (77/86). The positive rate of combined cross-filling test was 36.05% (31/86) and the negative rate was 63.95% (55 / 86). The incidence of cerebral ischemia after arterial occlusion was 8.33% (3/36). The rate of technical complications was 3.49% (3/86). Conclusions (1) At present, BOT can provide basic and accurate assessment results. (2) cross-filling test and buck test can effectively improve the specificity of BOT. (3) The combination of the traditional method and the new imaging technology, to find objective and quantitative indicators as a criterion for the future direction of the BOT improvement.
