The postcava tumor thrombosis had about 1/3 of patients with renal cell carcinoma at the initial examination. Reconstructive interventions were performed on the postcava for 38 patients (24 men, 14 women). The postcava thrombectomy was applied in 15 patients. The thrombectomy with postcava resection were carried out in 13 patients and plasty- in 6, prosthetics-in 4. An actuarial 3-year or 5-year survival rate of patients consisted of 59.4% and 42.2%. The performance of reconstructive interventions on postcava with its involvement was justified and provided satisfactory results in patients with renal cell carcinoma.
