Samwel Mikaye/LinkedIn Samwel Mikaye, Medical Doctor at MSK, shared a post on LinkedIn: 'Deep Vein Thrombosis (DVT) Deep vein thrombosis is a blood clot that forms in a deep vein, most commonly in the leg. It can be dangerous because part of the clot can break off and travel to the lungs, causing a pulmonary embolism (PE). Common signs and symptoms Usually affects one leg: Swelling of the leg, ankle or calf Calf or thigh pain/tenderness Warmth over the affected area Redness or discoloration A feeling of heaviness or tightness in the leg Some DVTs may have no symptoms. Risk factors Pregnancy and the postpartum period Recent surgery or hospitalization Prolonged immobility or long-distance travel Previous DVT/PE Cancer Obesity Smoking Estrogen-containing contraceptives or hormone therapy Certain inherited clotting disorders Diagnosis Clinical assessment can include the Wells score, followed by: D-dimer in appropriate patients Compression/Doppler ultrasound of the affected limb Treatment Confirmed DVT is usually treated with anticoagulation, such as: Low-molecular-weight heparin (LMWH) Direct oral anticoagulants (DOACs) Warfarin in selected situations The choice depends on factors such as pregnancy, kidney function, cancer, bleeding risk and other medications.
