[Severe hypertension and renal infarct. Physiopathology and treatment. Apropos of 1 case].

Renal infarction can be complicated by arterial hypertension, which is sometimes severe and may present as hypertensive encephalopathy and epilepsy. We report such a case in whom angiographic studies revealed a stenosis of the left renal artery and a post-stenotic aneurysmal dilation, containing a large thrombus with distal embolization. Thrombolysis associated with angioplasty resulted in the disappearance of the thrombus and correction of the stenosis. The pathophysiology of hypertension secondary to renal infarction is discussed. Therapeutic modalities are reviewed.
