What is it called when an artery ruptures?

What is it called when an artery ruptures?

An aneurysm—a balloon-like bulge in an artery—can develop and grow for years without causing any symptoms. But an aneurysm is a silent threat to your health. If an aneurysm grows too large, it can burst open, or rupture, and lead to dangerous bleeding inside the body.

What is the dilation of arteries?

Vasodilation refers to the widening, or dilation, of the blood vessels. It is a natural process that increases blood flow and provides extra oxygen to the tissues that need it most. In some cases, doctors may deliberately induce vasodilation as a treatment for certain health conditions.

What is vascular dilatation?

Vascular dilatation is a normal, physiologic process by which the blood-supply of an organ is increased during physiologic activity. It is an adaptive mechanism.

What causes coronary artery dilation?

Coronary dilatation is isolated ectasia in association with connective tissue disorders, such as scleroderma, in Ehlers–Danlos syndrome, in different types of ANCA-related vasculitis (2), and also in syphilitic aortitis and Kawasaki disease. (3) In a small percentage of patients, CAE can be congenital in origin.

What causes dilation of blood vessels?

Vasodilation occurs naturally in your body in response to triggers such as low oxygen levels, a decrease in available nutrients, and increases in temperature. It causes the widening of your blood vessels, which in turn increases blood flow and lowers blood pressure.

Which is the smallest blood vessel?

capillaries
Arterioles carry blood and oxygen into the smallest blood vessels, the capillaries. Capillaries are so small they can only be seen under a microscope. The walls of the capillaries are permeable to oxygen and carbon dioxide.

How do you dilate your coronary arteries?

Some coronary stenoses are compliant and are capable of changes in caliber. Drugs that dilate large coronary arteries, such as nitroglycerin and the calcium channel-blocking agents, can dilate these stenotic segments. This dilation may contribute to the relief of myocardial ischemia by increasing coronary blood flow.

What happens if coronary arteries are dilated?

Dilated segments are thought to change the rheology of blood in the affected vessel. Sluggish or turbulent blood flow may then predispose to myocardial ischaemia and its sequelae, including sudden death. The risk of ischaemic events is increased, regardless of the status of coexisting coronary lesions.
