Retrospection of Artery Balloon Test Occlusion of Internal Carotid Occlusion

Aim:To summarize our experiences in balloon occlusion test (BOT) of internal carotid artery (ICA),and value of the safety and effectiveness of BOT through case retrospection. Methods:Temporary occlusion of ICA was accomplished endovascularly by using balloon-catheter combination in 73 patients with cavernous sinus aneurysms. 46 patients who were negative in BOT were performed by permanent balloon occlusion of ICA.Results:Positive rate of BOT was 26.4%,21.7% in women and 33.3% in men. Positive rate of BOT of left ICA was higher than of right in women,whereas,there was no difference between right left in men. Complications related to BOT procedure occurred in 2.7% including one death. Ischemic stroke occurred in 4.3% after permanent ICA occlusion in BOT negative patients. Conclusion:BOT of ICA is a safe and effective method to test the patient’s tolerance to occlusion of ICA.
