Intracranial aneurysm surgery is mainly divided into craniotomy clipping and interventional therapy, interventional therapy is endovascular treatment, i.e. embolization surgery, two kinds of surgical procedures are as follows: 1, craniotomy procedure is to do surgical preparation after admission to the hospital, and do craniotomy. Craniotomy, the surgical steps for the scalp open, then open the bone, the brain apart to find the aneurysm clamping, clamping after judging the blood flow, and then do perfusion, and then do the later treatment; 2, interventional therapy is to do imaging clear aneurysm, and at the same time, can start to do the embolization treatment. The degree of damage of both methods is not the same, the damage of craniotomy is relatively larger, and the damage of interventional surgery is smaller. These two methods of aneurysm treatment are very good methods, most of the aneurysms are able to use both methods, and very few aneurysms can only use one method.
