Clinical Causes: Hormonal changes during pregnancy that increase blood coagulability Reduced blood flow in the legs due to pressure from the growing uterus Reduced physical activity, especially in the later stages of pregnancy Previous history of blood clots or genetic clotting disorders Obesity or overweight status Dehydration, which can thicken the blood Limited mobility or bed rest during pregnancy

Key Symptoms: Swelling in one leg, often the calf or thigh Pain or tenderness in the affected leg, especially when standing or walking Warmth and redness around the swollen area Discoloration of the skin, which may appear bluish or pale Possible sensation of heaviness in the affected limb

Diagnosis Path: Diagnosing DVT during pregnancy involves a combination of physical examination and imaging tests. Healthcare providers may use ultrasonography to visualize blood flow in the veins and identify clots. D-dimer blood tests, which detect a substance released when a blood clot breaks down, are less reliable during pregnancy but may still be considered. In some cases, other imaging studies like venography or magnetic resonance imaging (MRI) can be recommended to confirm the diagnosis while ensuring the safety of both mother and fetus.

Treatment Protocols: Managing deep phlebothrombosis in pregnancy usually involves anticoagulation therapy to prevent clot growth and reduce the risk of pulmonary embolism. The most common medication used is low molecular weight heparin, which is safe during pregnancy. Regular monitoring and dose adjustments are essential. Additional management strategies include emphasizing mobility, elevating the affected limb, and wearing compression stockings. The treatment plan is tailored to the individual, considering the stage of pregnancy and overall health status. Close follow-up with healthcare providers is vital to monitor the condition and prevent complications.
