Why does my husband need Lovenox shots when he had a filter placed?

My husband had a blood clot in his left leg. They put in a Celect filter. Now he has to take Lovenox shots every day. Why when we were told the filter would work?

Jorge F. Guttin, MDUsually the filter is inserted into the Inferior Vena Cava to prevent blood clots from traveling upward toward the heart and lungs. Anticoagulation is aimed at preventing/decreasing size of blood clots. I suspect Lovenox therapy is temporary. Consult further with your cardiologist.
