- A brain (cerebral) aneurysm is a bulging, weak area in the wall of an artery that supplies blood to the brain. In most cases, a brain aneurysm causes no symptoms and goes unnoticed. In rare cases, the brain aneurysm ruptures, releasing blood into the skull and causing a stroke. High blood pressure. 2  The risk of subarachnoid hemorrhage is greater in people who have a history of high blood pressure. 3  Smoking. 4  In addition to being a cause of high blood pressure, the use of cigarettes may greatly increase the chances of a brain aneurysm rupturing.

- A brain aneurysm occurs when a weak spot in your brain’s arterial wall bulges and fills with blood. Aneurysms are unpredictable and may not show any symptoms until they rupture. Some aneurysms are caused by brain injury, but inherited conditions and a family history of aneurysm can also affect whether you are at risk.

Overview An aneurysm is an abnormal widening or ballooning of an artery due to weakness in the wall of the blood vessel. Aneurysms are dangerous because they may burst, spilling blood in the area surrounding the blood vessel. The disease can occur in the aorta, in a blood vessel in the brain, or in a peripheral blood vessel.

What is vasospasm and how does it relate to a brain aneurysm? A Honor Society of Nursing (STTI) answered. Vasospasm is a spasm of the blood vessels. After a brain aneurysm ruptures, the brain's blood vessels may expand and contract rapidly. This action can restrict blood flow to the brain leading to stroke and additional brain damage.

Overview A brain aneurysm (AN-yoo-riz-um) is a bulge or ballooning in a blood vessel in the brain. It often looks like a berry hanging on a stem.A brain aneurysm can leak or rupture, causing bleeding into the brain (hemorrhagic stroke).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. brain aneurysm (AN-yoo-riz-um) is a bulge or ballooning in a blood vessel in the brain.

These include: head trauma.

Aneurysms and Dissections An aneurysm is a balloon-like bulge in a blood vessel or in the wall of the heart. An aneurysm occurs when the wall of a blood vessel or the heart becomes weakened. Pressure from the blood forces it to bulge outward, forming what you might think of as a blister. An aneurysm can often be repaired before it bursts.

Cerebral Aneurysm A brain aneurysm (also called a cerebral aneurysm or an intracranial aneurysm) is a ballooning arising from a weakened area in the wall of a blood vessel in the brain. If the brain aneurysm expands and the blood vessel wall becomes too thin, the aneurysm will rupture and bleed into the space around the brain.

Aortic Aneurysm - Topic Overview An aortic aneurysm (say a-OR-tik AN-yuh-rih-zum) is a bulge in a section of the aorta, the body's main artery. The aorta carries oxygen-rich blood from the heart to the rest of the body. Because the section with the aneurysm is overstretched and weak, it can burst. If the aorta bursts, it can cause serious bleeding that can quickly lead to death.
