우측내경동맥 폐쇄를 지닌 환자에서 식후 저혈압으로 유발된 반복적인 일과성 뇌허혈증

Abstract

We report a 72-year-old man suffering from recurrent attacks of transient drowsy mentality during meal or on orthostatic body position. Markedly disturbed collateral blood flow to right hemisphere was observed on conventional cerebral angiography. Acute and old ischemic lesions in the right internal borderzone area were also noticed on magnetic resonance image. Postprandial and orthostatic hypotension in the present case could be the cause of the recurrent neurological deficit developed in the primarily disturbed collaterals in the right middle cerebral territory
