A brain aneurysm 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.
Most brain aneurysms, however, don’t rupture, create health problems or cause symptoms. Such aneurysms are often detected during tests for other conditions.
An aneurysm appears when the wall of an artery weakens, resulting in a huge bulge. This bulge has the potential to rupture, resulting in an internal hemorrhage. Aneurysms can happen anywhere in the body, although they’re most prevalent in the brain, legs, aorta, and spleen.
Aneurysms have no symptoms and are not perilous. Some, however, can burst at their most severe stage, resulting in life-threatening internal bleeding. High blood pressure and atherosclerosis are the most common causes.
Infections and certain wounds can also result in aneurysms. Genetic conditions or congenital disabilities can also contribute to the aneurysm.
Swelling and pain are common symptoms of aneurysms that form near the body’s surface. It’s also possible that a big mass will begin. Aneurysms that have burst anywhere in the body might cause the following symptoms: bruising increased heart rate, pain, dizziness, or lightheadedness
The diagnostic methods used to discover arterial damage are frequently dependent on the problem’s location. A specialist, such as a cardiothoracic or vascular surgeon, may be recommended by your doctor. To identify or locate blood vessel abnormalities, CT scans and ultrasound technologies are commonly employed.
The aneurysm’s location and kind usually determine treatment. An endovascular stent graft, for example, may be required to repair a weak region of a vessel in your chest or abdomen. Medications for high blood pressure and excessive cholesterol are examples of other treatments.
