[Use of 'Korona' cava filter in oncological patients].

Using the 'Korona' cava filter in a total of 1345 oncological patients revealed regularity of a change in the shape of the inferior vena cava at the level of implantation. This made it feasible to determine one of the causes of long-term complications following implantation of other models of cava filters. The absence of clinically significant complications in the remote period after using this model of cava filter made it possible to implant it for a longer period, which is of special importance in oncological patients.
