We evaluate the effectiveness of TCD monitoring for detection of distal embolism just after Interventional treatment for cerebrovascular disease. Material and methods : Thirteen cases of cerebrovascular disease undergoing Interventional treatment were subjected to TCD monitoring just after intervention to detect distal embolization. Seven cases of internal carotid artery (ICA) stenting, 1 PTA of middle cerebral artery (MCA), and 5 GDC embolization of intracranial aneurysm were assessed by 30 minutes of TCD monitoring by transtemporal insonation and countered HITS. Antithrombin and antiplatelet therapy were administered after intervention in all cases. Results : HITS was detected in 3 of 13 cases, and 1 of the 3 cases had an embolic event (RIND) . The number of HITS in symptomatic case were 36 per 30 minutes and in asymptomatic case were 2 and 4 per 30 minutes. On post-therapeutic DWI of MRI, 3 of 13 cases had procedure-related infarctions and 1 of the 3 cases was symptomatic with a high number HITS. Conclusion : TCD monitoring during the early postoperative phase of intervention is effective in predicting embolic events.
