The goddess Chinnamastā squirting blood. Blood squirt (blood spurt, blood spray, blood gush, or blood jet) is a projectile expulsion of blood when an artery is ruptured. Blood pressure causes the blood to bleed out at a rapid, intermittent rate in a spray or jet, coinciding with the pulse, rather than the slower, but steady flow of venous bleeding.
External bleeding is generally described in terms of the origin of the blood flow by vessel type. The basic categories of external bleeding are: Arterial bleeding: As the name suggests, blood flow originating in an artery. With this type of bleeding, the blood is typically bright red to yellowish in colour, due to the high degree of oxygenation.
In the legs, bypass grafting is used to treat peripheral vascular disease, acute limb ischemia, aneurysms and trauma.While there are many anatomical arrangements for vascular bypass grafts in the lower extremities depending on the location of the disease, the principle is the same: to restore blood flow to an area without normal flow.
Symptoms may include chest pain, shortness of breath, leg pain, problems speaking, or problems moving parts of the body. [1] As clotting factors and platelets are used up, bleeding may occur. [1] This may include blood in the urine, blood in the stool, or bleeding into the skin. [1] Complications may include organ failure. [2]
Arterial thrombosis is the formation of a thrombus within an artery. In most cases, arterial thrombosis follows rupture of atheroma (a fat-rich deposit in the blood vessel wall), and is therefore referred to as atherothrombosis. Arterial embolism occurs when clots then migrate downstream and can affect any organ. [12]
Typically, a healthy person can endure a loss of 10–15% of the total blood volume without serious medical difficulties (by comparison, blood donation typically takes 8–10% of the donor's blood volume). [3] The stopping or controlling of bleeding is called hemostasis and is an important part of both first aid and surgery.
As a result of this blockage, blood flow in the vessel stops—a condition called thromboembolism. [ 1 ] Thromboembolism is a condition in which a blood clot ( thrombus ) breaks off from its original site and travels through the bloodstream (as an embolus ) to obstruct a blood vessel, causing tissue ischemia and organ damage.
Acute limb ischaemia (ALI) occurs when there is a sudden lack of blood flow to a limb [1] within 14 days of symptoms onset. [2] On the other hand, when the symptoms exceed 14 days, [3] it is called critical limb ischemia (CLI).
