Abstract:
Objective To investigate the relation between the balloon occlusion test ( BOT) and the anatomy of the circle of Willis ( CW) , and to explore the role of balloon occlusion test in the treatment of internal carotid artery permanent occlusion. Methods Selected the clinical data of 49 patients (52 sides) who had BOT in our hospital from October 2009 to June 2015,and analyzed the relationship be-tween the occurrence rate of anterior communicating artery ( AcoA) / posterior communicating artery ( PcoA) and the positive rate of BOT retrospectively. Results The occurrence rate of the AcoA was 97. 9%, and the occurrence rate of PcoA in one side was 82. 7%. Negative rate BOT accounted for 92. 3% and AcoA occurred in all, while the positive rate accounted for 7. 7%, including 2 cases of right superior ar-teria cerebri anterior combined with ipsilateral PcoAs absence, 1 case of left superior arteria cerebri anterior combined with ipsilateral PcoAs absence, and 1 case of AcoA and PcoAs absence. Conclusion Before the permanent occlusion of the internal carotid artery, it’ s necessary to clarify the redistribution of the compensatory way of blood flow in the AcoA-absent cases. Implementing permanent occlusion for cases with complete circle of Willis would cause less ischemic risk.
