Takayasu's arteritis is a nonspecific inflammatory arteritis involving the aorta and its major branches. Stroke may be an important and predictive complication for the prognosis in such patient. A 48-year-old woman got a bypass operation 3 months ago because of both subclavian artery and left common carotid artery occlusion, but she still suffered from headache, dizziness and tingling sensation and had no pulse of right arm. So, she got a bracheoaxillary bypass reoperation. Anesthesia was performed with enflurane-N2O-O2. At the recovery room, her mental state was deep drowsy and she revealed high blood pressure and abnormal neurological sign. Her brain computed tomography revealed cerebral hemorrhage at left frontotemporal basal ganglion area. Emergent hematoma removal of brain was done. Post- operatively this patient sustained an intracerebral hemorrhage in the initial hemorrhagic site despite immediate reoperation. She was discharged home without improvement at postoperative 5 days. This report is a description of Takayasu's arteritis with massive cerebral hemorrhage following a reoperation of occluded bypass surgery.
