What is thrombosis?

Thrombus 1

Thrombosis is the formation of a blood clot within a blood vessel which can cause a partial or total obstruction of the blood flow trough the circulatory system. Under normal condition, blood clot forms when blood vessels are injured preventing blood loss. death. Blood clots can form under certain conditions even when a blood vessel is not injured.

When thrombus are partially or completely detached from the blood vessel walls can cause embolism to the vital organs such as heart, lungs, brain or arteries in the legs. As the free thrombus travels through the circulatory system it can obstruct blood flowing and life threatening conditions such as heart attack, pulmonary embolism, stroke or limb-gangrene.

Thrombolytic agents are compounds that break down the thrombus (blood clot) itself.
