LEIOMYOSARCOMA OF THE INFERIOR VENA-CAVA - RESECTION AND RECONSTRUCTION OF THE RENAL-VEIN USING THE GONADAL VEIN

We succeeded in surgically resecting a leiomyosarcoma of the inferior vena cava (IVC), which originated at the confluent portion of the righ t renal vein (RRV), together with the IVC and RRV, and also were able to preserve the right kidney by reconstructing the RRV with end-to-end anastomosis using the right gonadal vein, A good blood flow of the re constructed RRV was thereafter confirmed by color Doppler ultrasonogra phy, and the renal function was also satisfactory, This new procedure, a reconstruction of the RRV using the gonadal vein, has not been prev iously reported, but is considered to be an easy and effective method which enables the surgeon to preserve the normal right kidney.
