title: Venous reconstruction of the inferior vena cava bifurcation for retroperitoneal rhabdomyosarcoma in a child. Case report.
abstract: Retroperitoneal tumors, as well as traumatic lesions and occlusions of the bifurcation of the inferior vena cava (IVC) and the common iliac veins may require venous vascular reconstruction. We present a method for inferior vena caval bifurcation reconstruction which employs the advantages of a large size straight expanded polytetrafluorethylene (ePTFE) graft in this position after a new IVC bifurcation has been created by uniting the stumps of both common iliac veins, and construction of an arteriovenous (A-V) fistula with controlled flow to decrease the rethrombosis rate of the graft, and still not cause heart failure. This method was used in a case of recurrent rhabdomyosarcoma in an 8 year old child encroaching upon the bifurcation of the IVC as well as on both common iliac veins. The situation was managed by radical resection of the tumor and by creating a new caval bifurcation of the common iliac veins, followed by interposition of a straight ePTFE graft. An A-V fistula was created between the left femoral vein and left femoral artery using the left greater saphenous vein in controlled fashion. The arterial defect of the right common iliac artery was reconstructed by interposition of a PTFE graft end-to-end.
