Is an aneurysm cancer? What is the treatment for an aneurysm?

Aneurysms are not cancer. Aneurysms are tumors that protrude from the arterial wall due to localized abnormal expansion of the lumen of a cerebral artery. Intracranial aneurysms are mainly cystic swellings caused by local congenital defects in the cerebral artery wall and increased cavity pressure, which is the first cause of subarachnoid hemorrhage.

The causes of aneurysms are summarized as follows:

① Congenital factors;

② Arteriosclerosis;

③Infection;

④Trauma.

1. Collateral circulation should be fully established. Generally, surgery is performed 3 to 6 months after the aneurysm appears. If conditions for arterial transplantation are available, surgery can be performed earlier.

2. In any of the following situations, surgery should be performed urgently or as soon as possible:

① Those with ruptured aneurysms or those whose aneurysms are rapidly enlarging and tend to rupture;

② Severe ischemia of the limbs or brain tissue distal to the tumor, affecting limb survival or brain damage that is life-threatening;

③Aneurysm infection;

④When the adjacent tissues and organs are severely compressed;

⑤When a dissecting aneurysm is formed.

3. Surgical Method

① Aneurysm resection, end-to-end arterial anastomosis or vascular transplantation. Carotid aneurysm surgery is based on the Matas test, which uses hypothermic anesthesia to minimize the time of blood flow blockage or temporarily divert blood flow inside and outside to maintain blood perfusion in the brain tissue.

② Endovascular repair of aneurysms: It is suitable for pseudoaneurysms or aneurysms that are closely adhered to adjacent nerves and blood vessels.

③Aneurysm tangential resection and arterial repair. Applicable to cystic aneurysms.

④ Aneurysm encapsulation: It is suitable for aneurysms that cannot be removed or the patient cannot tolerate removal.

⑤ Ligation of the proximal and distal arteries of the aneurysm, bypass transplantation of autologous veins in the anatomical position, and drainage of the aneurysm cavity. Applicable to infected aneurysms.
