一位64岁女性，左侧颈内动脉（伊卡）闭塞，在颞浅动脉与大脑中动脉吻合后出现暂时性神经功能恶化。术前单光子发射计算机断层扫描（SPECT）显示左侧伊卡区域的脑灌注储备明显减少。术后18小时突然出现失语症。随访SPECT显示左颞叶暂时性灌注过度，强烈表明这种不寻常的并发症是由于慢性严重缺血和自动调节受损的脑组织分流所致。
A 64-year-old female with occlusion of the left internal carotid artery (ICA) developed temporary neurological deterioration after superficial temporal artery to middle cerebral artery anastomosis. Preoperative single photon emission computed tomography (SPECT) showed marked reduction of the cerebral perfusion reserve in the left ICA territory. She suddenly developed aphasia 18 hours after operation. Follow-up SPECT revealed temporary hyperperfusion in the left temporal lobe, strongly suggesting that this unusual complication resulted from bypass flow into the brain tissue with chronic severe ischemia and impaired autoregulation.
