Anticoagulant therapy remains the mainstay of medical therapy for deep venous thrombosis (DVT) because it is non-invasive, it treats most patients (approximately 90%) with no immediate demonstrable physical sequelae of DVT, it has a low risk of complications, and its outcome data demonstrates an improvement in morbidity and mortality. Meta-analyses of randomized trials of unfractionated heparin (UFH) and low-molecular-weight heparin (LMWH) have shown that they are similar, with a 4% risk of recurrent DVT, a 2% risk of pulmonary embolism (PE), and a 3% risk of major bleeding.
Prenatal care is always necessary in order to keep your healthy baby healthy even if there are no complications, good and consistent prenatal care can help prevent later complications.
