[Reconstructive interventions of the superior vena cava].

Twenty-nine reconstructions of the vena cava superior were performed: twice due to obliterating mediastinopericarditis, twice because of post-traumatic thrombosis, 4 times because of iatrogenic thrombosis, once because of an arteriovenous fistula and 24 times due to malignant tumours. In nine of the latter cases a large resection with prosthetic repair of the vena cava superior was necessary; one of these patients died and the others had no recurrence of thrombosis.
