Document Summary
Thrombus: a blood clot inside of a blood vessel. Embolus: a thrombus that breaks free from the blood vessel and travels. Thrombophlebitis: thrombosis associated with phlebitis (inflammation of the vein) Normally, blood only coagulates when it leaves the blood vessel. In this case, clotting is happening in an intact blood vessel (not ruptured) An arterial thrombosis will cause distal ischemia (this is critical) Thrombosis is a huge problem in atherosclerosis. * blood turbulence or stasis (stasis in the veins of the legs, turbulence in the arteries, particularly where the arteries divide such as the abdominal aorta into the two femoral arteries) * infections of the blood vessels (in the heart especially, bacteria attacks blood vessels of the heart) Types of embolus: thromboembolus: thrombus that has detached, air: injecting air into the vein, travel, block blood vessel/capillary, scuba diving if they ascend really fast.
