[Fibromuscular dysplasia of the renal arteries].
Thirty-two cases of fibrous-muscular dysplasial of renal arteries (including one autopsy case) were studied. Sections of renal arteries removed at reconstructive operations from patients suffering from renovascular hypertension were examined. Two morphological variants of the process were distinguished: medial dysplasia (perimedial fibroplasia, medial fibroplasia, and dissecting aneurysm) and intimal proliferation. Morphologically, fibrous-muscular dysplasia is a manifestation of proliferation of smooth muscle cell which appears to have various forms and stages. Diagnostically, fibrous-muscular dysplasia should be differentiated from atherosclerosis, nonspecific arteritis, proliferation of the intima due to hypovolemia, and perivascular sclerosis of different etiologies.
