Deep-vein thrombosis - DVT

Medium urgency
Common-

Deep Venous Thrombosis (DVT) is caused by the formation of a blood clot in a vein of the body, mainly deep veins of the legs. 

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

Immobility, smoking, obesity, some medications and certain blood diseases may favor this pathology.

It manifests with pain, swelling, redness and heat in the affected extremity.

The diagnosis is made through clinical history and physical examination.

Treatment includes analgesics/anti-inflammatory drugs to alleviate pain and inflammation, thrombolytics to break up the clot and anticoagulants to prevent the formation of new thrombi.
