The spring coil embolization procedure is generally used to treat intravascular aneurysms. It can change the direction of blood flow through the aneurysm by spring-ring embolization, but there are certain disadvantages: 1. During embolization, some aneurysms are very weak and may rupture during the embolization process, which is very critical. After embolization, there is a possibility that some embolization may be excessive and cause cerebral infarction by compressing the surrounding blood vessels, which may cause more serious damage, and sometimes some endothelial damage and thrombus may occur, causing cerebral blood supply deficiency and cerebral vascular spasm in the future. This is not conducive to the stability of the disease after surgery.
