What is Deep Vein Thrombosis (DVT)?

A deep vein thrombosis (DVT) is a blood clot within a deep vein. A clot inside a blood vessel is called a thrombosis. DVT predominantly develops within the legs and may not be accompanied with any symptoms. The non-specific symptoms of DVT include pain, swelling, redness, warmness, and engorged superficial veins (‘spider veins’) in the leg. DVT may go away naturally, but serious complications can develop when a thrombosis dislodges and travels to the lungs to become a life-threatening pulmonary embolism. DVT and PE are the two manifestations of the disease venous thromboembolism. A late complication of DVT is the post-thrombotic syndrome, which can manifest itself as oedema, pain or discomfort and skin problems.

In addition to anti-coagulation treatment, graduated compression socks or stockings, that apply a firm pressure at the ankles and graduate to a lower pressure towards the knees, are recommended for those at risk of developing, showing symptoms of, or diagnosed with DVT.

Factors related to DVT:
Besides inherited attributes, there are many other factors that exacerbate the development of DVT:
