[Traumatic thrombosis of the renal artery]

The authors describe five cases of radiological diagnosis of traumatic thrombosis of the renal artery, paying special attention to the aortography as a positive source of information able to provide on its own a guide to rapid and correct treatment. Special reference is made to the positive errors of filling of the excretory duct in the I.V.U. in the said traumatic thrombosis; a picture which is well produced due to the existence of polar arteries or because the thrombosis is distal to the start of the capsulo-adrenal artery branch which may produce nephrograms due to perforating arteries.
