Thrombosis, also referred to formation of a blood clot (thrombus) in a blood vessel, is an often undiagnosed and untreated condition with severe repercussions. With about fifteen different types of thrombosis affecting different parts of the body, the most asymptomatic is Deep Vein Thrombosis (DVT). To understand why DVT is so problematic, one must first understand what deep veins are. Deep veins are much farther away from the skin than other veins. When a clot is formed in one of the deep veins, if untreated, it could potentially travel through the circulatory system and get settled in other parts of the body (also known as thromboembolism).

There are three major factors that can lead to clot formation: restricted or limited movement; damaged blood vessels, possibly caused by certain surgeries or pressure in the blood vessels; and disturbance in the pattern of the blood flow, which leads to stagnation of blood in the arteries or veins.
