Portal-systemic shunt through the right renal vein developing following portal tumor thrombus.
Despite the semi-routine use of color Doppler sonography for evaluating portal circulation abnormalities, there is a relative paucity of information on portal-systemic (P-S) shunt through the right renal vein (P-SR shunt). We report such a case. The patient was a 60-year-old woman with hepatocellular carcinoma on liver cirrhosis. Serial sonography showed an aggravation in findings; an increase in the size of the tumor was followed by formation of a portal tumor thrombus, and then occurrence of a P-SR shunt. We present this case, with a comparison between the patient's clinical course and the color Doppler results. To our knowledge, this is the first report to make such a comparison in a P-SR shunt case. We also briefly review the literature.
