An aneurysm is an abnormal dilation or ballooning of a blood vessel or the wall of a blood vessel. This condition can weaken the vessel and potentially lead to rupture. Aneurysms commonly occur in the arteries of the brain or the abdominal aorta but can also develop in other areas of the body.

Aneurysms often do not cause symptoms and can silently grow. However, when a large aneurysm ruptures, it causes bleeding, which can be life-threatening. Some aneurysms may also cause symptoms such as headaches, vision problems, difficulty speaking, facial paralysis, or balance issues.

The treatment of aneurysms is determined based on the size, location, overall health of the patient, and potential risks associated with the aneurysm. Small and stable aneurysms are usually monitored, while large or rapidly growing aneurysms may require surgical intervention. Surgical treatment options include clipping the aneurysm, placing a stent, or performing endovascular coil embolization.
