Forty-two hypertensive patients with fibromuscular dysplasia who had angiographic evidence of the development of new disease or of the progression of existing disease were studied. Renal arterial disease was classified as medial fibroplasia with aneurysms (12 patients), subadventitial fibroplasia (24 patients), or intimal fibroplasia (6 patients). Progression of the disease was shown in all 42 patients during the follow-up period (from 1 month to 11 years and 4 months). The results indicate that all forms of fibromuscular dysplasia are progressive and have variable rates of progression.

The radiographic appearance and clinical significance of gastric varices in the absence of esophageal varices and secondary to splenic vein occlusion were studied. Eighteen patients were evaluated through medical records, angiography, and barium studies of the stomach and esophagus. The presence of splenic vein occlusion was determined by arteriography in 18 patients and its etiology confirmed by surgery in 17 patients. This condition should be suspected in patients with chronic abdominal pain, weight loss, and iron deficiency anemia who show fundal polypoid filling defects or prominent gastric folds on an upper GI series.

A case is presented of renal artery stenosis causing renin-dependent hypertension 11 1/2 years after irradiation for Wilms tumor. The literature was reviewed briefly for other cases of large artery damage after irradiation therapy.

Only one of these was confined to the right renal vein, while 1 1 extended through the renal vein into the inferior vena cava. Eight of the 1 3 group III tumors (greater than 7 cm) showed venous extension.

Six patients were evaluated by angiography for dorsalis pedis free flap transfer because the course of the dorsalis pedis artery could not be traced by palpation. Two were subsequently excluded because they showed vascular occlusions. Successful transfer depends on the dorsalis pedis artery and its branches being intact, while healing of the donor site depends on the function of the posterior tibial artery. Angiography was found to be helpful in determining both of these factors.
