title: High venous pressure in the main renal vein causing development of peritransplant venous collaterals in renal transplant patients: a rare finding.
abstract: We will show the sonographic appearance of peritransplant venous collaterals in renal transplants with renal venous hypertension. Three cases of renal transplants with pericapsular vessels were identified at our institution. Two cases were related to renal vein thrombosis. The third case had pericapsular vessels secondary to venous hypertension from arterialization of the transplant renal vein by a preexisting right thigh arteriovenous graft. The development of high venous pressures in renal transplants leading to the collaterals' venous drainage has been rarely described. This finding should be recognized as a rare complication of renal transplants but does not necessarily lead to transplant failure.
