[SURGICAL TECHNIQUE OF A RENAL ARTERY CONTROL WHILE REMOVAL OF TUMORAL THROMBI FROM VENA CAVA INFERIOR].

Efficacy and safety of a renal artery ligation after thrombectomy in comparison with those while using a standard surgical technique were studied. Possibility of performance and safety of thrombectomy without preliminary ligation of renal artery was proved. The results did not depend on level of intravenous tumoral spread and were significantly better, than while application of standard approaches to renal artery because of absence of embolic complications.
