[Clinical aspects and surgical treatment of thrombosis of the inferior vena cava (author's transl)].

The infrequent thrombosis of the inferior vena cava usually arises as a transmission of a thrombosis from a leg or pelvic vein. The indication for treatment must be made early and quickly, because only complete removal of the thrombus is sufficient. The operation we recommend is transperitoneal or retroperitoneal exposure of the inferior vena cava and pelvic veins, By this method the detachment of thrombi during the operation with consequent pulmonary emboli can be prevented. On the other hand, it is possible to remove, under direct vision, thrombi extending into the renal veins. The 3 cases presented show this and therefore both the surgical treatment and the technique used for the treatment of thrombosis of the inferior vena cava can be recommended without restriction.
