A Case of Spontaneous Renal Artery Dissection Causing Renal Infarction in a Previously Healthy Man / 대한신장학회잡지

ABSTRACT

Spontaneous renal artery dissection is an uncommon cause of renal infarction. Previous reports of spontaneous renal artery dissection has been associated with hypertension or fibromuscular dysplasia. We report herein the case of a previously healthy, normotensive patient with renal infarction due to spontaneous renal artery dissection who remained normotensive throughout his course without therapy. A previously healthy 31-year-old man with well- documented normotension had a sudden onset of right flank pain and delayed onset of elevation of lactic dehydrogenase, hematuria, and proteinuria. Thin section spiral computerized tomogram shows linear intraluminal filling defect suggesting intimal flap. Angiography shows dissection of main right renal artery. Six months later, he has remained well and normotensive without therapy. To our knowledge, this is the first case of spontaneous renal artery dissection in normotensive patients in Korea.
