ABSTRACT

Review of our experience in the diagnosis and treatment of 44 patients with inferior vena cava tumoral thrombosis (IVCTT), associated or not to other neoplastic processes 34 hypernephroma, 2 cava leiomyosarcoma, 1 paratesticular rhabdomyosarcoma and 1 biphasic synovial sarcoma. Twenty-five patients with hypernephroma and tumor thrombi in the ipsilateral renal vein only were excluded from the analysis since this fact did not change the usual therapeutic approach. In the 19 remaining patients, concomitantly to the primary tumour exeresis a thrombectomy was performed, using cavotomy with proximal and distal clamping in 11 patients and cardiopulmonary by-pass, deep hypothermia and cardiocirculatory arrest in 8 patients. The paper analyzes the radiological investigations performed in order to reach a IVCTT diagnosis, and reviews the related literature.
