RENAL VEIN THROMBOSIS DEMONSTRATED BY SELECTIVE RENAL PHLEBOGRAPHY.

Selective renal phlebography is a relatively new procedure, with few reports in the literature of its technic or applications. Recently, the authors encountered a case of renal trauma with subsequent renal vein thrombosis. The thrombus was demonstrated by selective renal vein catheterization and phlebography. The purpose of this paper is to report the case, to review the radiographic diagnosis of renal vein thrombosis, and to discuss the technic and applications of selective renal phlebography. Method Radiographic demonstration of the renal veins has been accomplished by several methods. Delayed films following renal arteriography often disclose filling of the main renal veins. Inconsistency of opacification and lack of detail, however, render this method unreliable for diagnosis. The renal veins may, at times, be visualized during inferior vena cavography. Helander and Lindbom (1) have described the findings in the normal cavogram. Because of the large volume of blood diluting the contrast agent, streami...
