[Assessment of the results of implantation of an anti-embolic cava-filter using the method of ultrasonic scanning].

By the method of ultrasound scanning, 56 patients were examined at the early and 115 patients at the late period after the percutaneous implantation of a cava-filter. Ultrasound scanning was performed in the cross and longitudinal section planes. In 28 patients, the embolic occlusion of the cava-filter was revealed, in 19-thrombosis of infrarenal inferior vena cava (IVC). Neither migration of the cava-filter, nor damage to the IVC wall was revealed. Ultrasound scanning permits to define the thickness of the IVC wall at the zone of the implanted filter.
