What is a blockage in the vessels of the brain?

What is a blockage in the vessels of the brain?

Carotid artery disease occurs when fatty deposits (plaques) clog the blood vessels that deliver blood to your brain and head (carotid arteries). The blockage increases your risk of stroke, a medical emergency that occurs when the blood supply to the brain is interrupted or seriously reduced.

What is it called when a blood vessel ruptures?

The most serious threat of an aneurysm is that it will burst and cause a stroke or massive bleeding, which can be life-threatening. A large aneurysm can affect your circulation and lead to blood clots.

Is popping a blood vessel fatal?

Vessel rupture can cause bleeding into the interstitial lung tissue, into the airway (ie, bronchi), and into pleural space, and it can be life-threatening.

What happens when a blood vessel ruptures in the brain?

Hemorrhagic stroke. A hemorrhagic stroke occurs when a blood vessel ruptures, or hemorrhages, and then prevents blood from getting to part of the brain. The hemorrhage may occur in any blood vessel in the brain, or it may occur in the membrane surrounding the brain.

When does a cerebrovascular accident ( CVA ) occur?

Cerebrovascular accident (CVA) is the medical term for a stroke. A stroke is when blood flow to a part of your brain is stopped either by a blockage or the rupture of a blood vessel. One way is an embolic stroke, which occurs when a clot forms somewhere else in your body and gets lodged in a blood vessel in the brain.

What causes a blockage in the brain arteries?

Especially fatty deposits from too high cholesterol can accumulate in the major arteries and if such deposits dislodge they can block brain arteries causing a blockage and eventually an ischemic stroke. A final common reason for blockages of the brain arteries is caused by little blood clots.

Where does a ruptured brain aneurysm and stroke occur?

Most often a ruptured brain aneurysm occurs in the space between the brain and the thin tissues covering the brain. This type of hemorrhagic stroke is called a subarachnoid hemorrhage. A ruptured aneurysm quickly becomes life-threatening and requires prompt medical treatment.

What does cerebrovascular disease mean in medical terms?

Together, the word cerebrovascular refers to blood flow in the brain. The term cerebrovascular disease includes all disorders in which an area of the brain is temporarily or permanently affected by ischemia or bleeding and one or more of the cerebral blood vessels are involved in the pathological process.

What are the blood vessels in the brain called?

This blood vessel, like the posterior communicating artery, offers a protective effect by allowing the sharing of blood supply from the other side. The communicating arteries form part of a ring of vessels in the brain called the Circle of Willis .

What does cerebral infarction and cerebral thrombosis mean?

Glossary. Cerebral infarction – A stroke caused by interruption or blockage of blood flow to the brain; also called ischemic stroke. Cerebral thrombosis – Formation of a blood clot in an artery that supplies blood to part of the brain. Cerebrovascular – Pertaining to the brain and the blood vessels that supply it.
