[Deep leg and pelvic vein thrombosis in aplasia of the inferior vena cava].

Deep phlebothromboses of iliacal vein and aplasia of the inferior vena cava Coincidence of deep phlebothromboses of iliacal vein and aplasia of the inferior vena cava is a rare condition but has significance for further therapy. Two cases of this anatomical malformation with complications are presented and the importance of therapeutical strategies are discussed. We report on our experiences with the operative procedures of venous thrombectomy and arteriovenous fistula, aimed at increasing the venous flow in the collaterals of the aplastic inferior vena cava.
