Treatment of Aneurysm

Treatment of aneurysms depends on how big they are. Surgery to repair an aortic aneurysm is a major operation, and it is not usually recommended unless the aneurysm is large (bigger than 55mm wide). The surgical procedure involves replacing the part of the aorta affected by the aneurysm with a synthetic graft. This a tube made out of an elastic material that is very similar to a normal healthy aorta.

For small aortic aneurysms, (less than 55mm wide), the risk of death caused by surgery is generally more than the risk of the aneurysm rupturing. However, you must continue to have regular medical check ups to make sure the aneurysm is not growing.

For brain aneurysms, a specialised surgical procedure called a craniotomy is carried out to open the head. The aneurysm is found using a microscope, and a metal clip is used to clip the neck of the aneurysm. This seals it off without damaging the main artery. Sometimes the aneurysm is packed with a special type of glue to encourage the blood to clot and strong tissue to form. Sometimes the aneurysm may be managed with radiotherapy.

Aneurysm surgery is a major operation, and you will usually be kept in intensive care for one to two weeks afterwards to monitor your progress. It is very important to avoid any strain or exertion, and drugs are given to keep the blood pressure reasonably low. A drip will be used to make sure you get all the fluids you need.

Sometimes, the blood vessels can go into spasms following this type of operation. Drugs are given to control this and reduce the chance of brain damage. It is also important to prevent the clot that is forming in the aneurysm from dissolving. Antifibrinolytic drugs to prevent clots dissolving will often prevent re-bleeding from a dissolving clot.
