Objective To re-valuate the effect of EC-IC bypass surgery on ischemic cerebrovascular disease. Methods The clinical and follow-up data of 30 patients with STA-MCA bypass surgery were analyzed retrospectively. Results The patients' symptoms before surgery were TIA, RIND and atypical cerebral ischemic syndrome. There was no large size of cerebral infarction on CT and MRI, there were regional cerebral blood flow reduced area before surgery on SPECT ?rCBF. The patency rate of bypass surgery was 86. 7% verified by postoperative angiography, and the rate of improved regional cerebral blood flow was 70% postoperatively. There were 2 attacks of TIA in 2 patients and no complete stroke occurred during follow-up. The moderate neurological deficits before EC-IC bypass surgery in 8 patients were recovered partly during follow-up. Conclusion STA-MCA bypass surgery may effect to prevent complete stroke due to hemodynamic cerebral ischemia.
