Abstract

There is strong controversy as to whether to use filters temporarily in the inferior vena cava (IVC) during endovascular therapies for deep venous thrombosis (DVT) in the lower extremity. To evaluate the necessity of implantation of a retrievable inferior vena cava filter during treatment of DVT in the lower extremity using various endovascular techniques. Studied were all 37 consecutive sessions of endovascular treatments performed in 34 patients with symptomatic lower-limb DVT between April 2001 and October 2006. In all sessions, a Gunther tulip retrievable vena cava filter (GTF) was implanted during the procedures. The degree of trapped thrombus in the filter was evaluated by repeated venocavography. Implantation of a total of 66 GTFs was successfully performed in 37 sessions. Worsening of or new formation of pulmonary embolism was avoided in all patients. In 20 (54.1%) of the 37 sessions, a trapped thrombus in the filter was observed. In 14, the trapped thrombus was large, filling more than half the height of the filter. Temporary implantation of filters is effective in preventing pulmonary emboli during endovascular treatment of DVT in the lower extremities.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
