Aneurysm is a disease that occurs in blood vessels. It is the local expansion and deformation of the blood vessel wall and the formation of diverticula, which is called an aneurysm. The aneurysmal protrusion refers to the part of the blood vessel that protrudes through it. Once the blood vessel wall becomes weak, it may cause an aneurysm to rupture, leading to massive bleeding or even death. The main cause of aneurysm protrusion is the destruction of the blood vessel wall, which can be caused by metabolic abnormalities such as genetics, hypertension, smoking, and cardiovascular disease.

Aneurysmal protrusion is a serious disease clinically. Most patients may have no symptoms, but when the size of the aneurysm protrusion gradually increases, it may cause blood circulation disorders, neurological damage, loss of consciousness, and even death. Therefore, patients who have no obvious symptoms but have aneurysm protrusions should undergo regular medical examinations and take necessary treatment measures.

At present, the treatment methods for aneurysm protrusion mainly include craniotomy and non-craniotomy treatment. Craniotomy is risky, so non-craniotomy treatment is widely used. Non-craniotomy treatments mainly include wire bypass (bank treatment), stent implantation, endovascular embolization, interventional surgery, etc. With the continuous improvement of medical technology, the success rate of non-craniotomy treatment has gradually increased. More consideration should be given to the patient's specific condition and the balance of risks and benefits of treatment when selecting a treatment.
