Cerebral aneurysms are treated in different ways according to their size, shape, and neck opening width. Commonly used interventional treatment methods are as follows: 1.Aneurysm spring coil embolization: simple spring coil embolization can completely cure the aneurysm; 2.Balloon assisted aneurysm embolization: during the process of aneurysm embolization, the balloon will block the aneurysm node to achieve the embolization effect; 3.Stent assisted embolization: a stent is placed at the neck opening of the aneurysm, and oral aspirin and Bolivar are required at a later stage; 4.Blood flow guiding device: such as Pipeline device, which can change the direction of blood flow, reduce the blood supply to the aneurysm, and gradually make it form thrombus to achieve embolization effect; 5.Dense mesh stent: the stent completely closes the aneurysm, so that no blood flow enters to achieve embolization effect.
