[Spontaneous renal artery dissection].

The clinical clues of sudden arterial hypertension, acute pain in the side, proteinuria, hematuria, abdominal bruits and renal failure are suspicious for spontaneous dissection of the renal arteries, even in the absence of one or more of the above-mentioned symptoms. To confirm the diagnosis and to provide appropriate therapy, immediate renal arteriography is mandatory, otherwise acute loss of renal tissue may occur. We report on one patient with spontaneous dissection of the renal arteries.
