Medial Fibroplasia: Involvement of Renal Artery and Small Renal Arteries in Renal Vascular Hypertension

Dysplasia of the renal artery may cause renal vascular hypertension. The most common type of dysplasia is the medial fibroplasia. Medial fibroplasia, as well as the other types of dysplasia, has only been described in the main and primary branches of the renal artery. A case of medial fibroplasia, where arterial changes were seen far out in the small renal vessels is reported.
