A Case of Cerebellar Infarction with Renal Artery Stenosis / 대한뇌졸중학회지

Renal artery stenosis (RAS) is defined as a narrowing of main renal artery or its major branches over 50%, and can be the cause of pulmonary edema, renal failure, malignant hypertension and cerebrovascular diseases. The renin-angiotensin-aldosterone system works as a key role. In this paper, we report a case of a 53 year-old patient with left middle cerebellar peduncle infarction, who showed malignant hypertension and RAS. The RAS was diagnosed by renal artery computed tomography angiography and treated with renal artery angioplasty, stenting and antihypertensive medication. In a young patient with ischemic stroke who has refractory hypertension against antihypertensive medications, RAS should be suspected and evaluated.
