Management of deep vein thrombosis of the lower extremity in pregnancy.

Deep vein thrombosis (DVT) of the lower extremity during pregnancy is infrequent, but its complication, pulmonary embolism, remains an important cause of maternal mortality. To evaluate the best method of caring for patients with DVT, we reviewed the records of patients at the Charleston Area Medical Center from 1987-1992 who were treated for this condition. Twelve patients were treated with conventional continuous intravenous heparin for 7 days-10 days followed by subcutaneous heparin until 6 weeks-8 weeks after delivery.
