[Use of DIL-type cava filters for the prevention of thromboembolism of the pulmonary artery].
New type cava filters were employed to prevent pulmonary artery thromboembolism in 12 cases. DIL cava filter was used, that represents a string made of a special alloy that can 'memorize' its shape. The design of this filter is in principle different from all the known filters, for it functions as an intraluminal filter and at the same time stretches the vena cava inferior, enlarging its diameter in the frontal plane. The DIL cava filter proved to be effective in the majority of cases, but if the walls of vena cava inferior were too rigid, for example, if a tumor grew into them, it was difficult to place the filter properly. On the whole this filter is characterized by a number of advantages: it can be easily implanted via 7 F catheter without injuring the vena cava inferior walls. No cases of dislocation of cava filters in relation to bone markers were noted in 9 patients over 60 +/- 17 days.
