Which intervention is the primary treatment for VTE?

• A. Anticoagulant therapy
• B. Antibiotics alone
• C. Immediate ambulation with leg compression
• D. Vitamin K supplementation only

Answer: (A)

Anticoagulant therapy is the primary approach because it prevents the clot from growing and stops new clots from forming, which lowers the risk of a dangerous pulmonary embolism. By inhibiting parts of the coagulation cascade, these medicines give the body’s natural fibrinolytic system time to break down the existing clot and reduce the chance of the clot extending or breaking off. In pregnancy, low-molecular-weight heparin is commonly used because it is safer for the fetus and can be managed if bleeding occurs; other anticoagulants like warfarin or many direct oral anticoagulants are avoided during pregnancy. Antibiotics won’t treat a clot since they target infection, not coagulation. Immediate ambulation with leg compression does not address the clot itself and could increase the risk of embolization. Vitamin K supplementation is used to reverse anticoagulation or treat deficiencies, not to treat an active VTE.
