Deep-vein thrombosis - DVT

Medium urgency
Common-

Deep vein thrombosis (DVT) is a blood clot in a vein in the body, usually in the deep veins of the legs.

It is more common after the age of 50, in women, during pregnancy and in the postnatal period.

Immobility, smoking, obesity, some medications and certain blood diseases can predispose to this condition.

It usually presents with pain, swelling, redness and heat in the affected limb.

Diagnosis is made by history and physical examination.

Treatment includes analgesics and anti-inflammatory drugs to reduce pain and inflammation, thrombolytics to dissolve the clot, and anticoagulants to prevent new clots from forming.
