[Clinico-diagnostic criteria for application of antiembolic cava-filter at various terms after its implantation].
Cava-filter implantation procedure constitutes an effective method for the pulmonary thromboembolism surgical prophylaxis. After cava-filter implantation completion the ultrasonography, contrast cavagraphy and spiral computer tomography (CT) were performed of the vena cava inferior (IVC) portion in the site of embolcatching device installation. The cava-filters models investigated, owing the cone form without flattening part, make a jump while exiling from the delivery system and occupy angulation position in IVC lumen. The IVC wall perforation after the operation had occurred in 3 (1.6%) patients, in far remote period the neighboring organs wall perforation was observed in 17 (85%) patients. In late follow-up period the complete or partial IVC occlusion was noted at the site of the embolcatching devices residence with chronic venous insufficiency occurrence. Subsequent complex studying and essential improvement of antithrombotic cava-filters is needed for prevention of the filters application complications.
