Limited acute dissections of the abdominal aorta. Report of five cases.

Within a two year period, the diagnosis of acute dissection of a segment of the abdominal aorta was made in five cases without aneurysmal dilation or leakage and with virtually no ischaemia. All patients presented with an atypical painful abdominal syndrome and the diagnosis was made by computed tomography. Only one patient, suffering persistent pain was treated by resection and graft interposition of the infrarenal aorta.

Bilateral ureteral inverted papillomas in association with bladder carcinoma: a case report and review of the literature.

A case of multiple inverted papillomas of both ureters, in association with a bladder carcinoma, is presented. Inverted papilloma is a rare benign urothelial tumor. Because of its curability by conservative surgery, it should be considered in the differential diagnosis of a ureteral filling defect and ureteral obstruction.

Mesenteric infarction: a fatal complication of renal transluminal angioplasty.

In a 47-year-old patient with renovascular hypertension due to a totally obstructed left and a severe constricted right renal artery, a successful transluminal renal angioplasty was performed with normalisation of blood pressure. Thirteen days later the patient died of a mesenteric infarction, possibly caused by normalisation of the blood pressure in the presence of a severe mesenterical stenosis. The benefit of preventive screening of other vital organs in highly atheromatous patients is discussed.
