Abstract
The ideal treatment of calf vein thrombosis (CVT) remains undefined. We assessed practice patterns at a single institution for CVT. Physicians were sent an online survey with 8 multiple choice questions about management of CVT. A total of 99 physicians of varying specialties participated in the survey. A total of 48.5% anticoagulate patients with CVT and 51.5% do not. Of those who anticoagulate, 62.3% use low molecular weight heparin and 11% use IV heparin. Treatment duration is 3 months for 58% and 6 months for 30% of responders. Of those who do not anticoagulate, 71.2% reassess for clot propagation or resolution with a duplex exam. IVC filters are used by 46% when there is a contraindication to anticoagulation and 13.7% when clot propagation is noted on follow-up scan. These results suggest that there is no consensus treatment of CVT. There is a higher than expected rate of IVC filters placed for CVT.
