Abstract
Coil embolization of aneurysms, after more than 20 years of clinical practice shows that several conditions must be met: 1. After the necessary interval, the entire aneurysm can achieve and maintain effective hemostasis. 2. Intra-aneurysm thrombosis is the result of intra-aneurysm hemostasis induced by the coil, which must take the necessary time to form a stable and organic coil thrombus complex; 3. The homogeneity and stability of the spring-thrombus complex at the base of the aneurysm must be sufficient to ensure neoendotheliosis and re-endothelialization of the aneurysm neck. Only if the above conditions are met can the operation be successful. The advantage of stent-assisted coil embolization is that the tumor bearing vessel can be preserved. However, since the foreign body is permanently placed in the main vessel, antiplatelet drugs need to be continued after surgery in order to prevent thrombus.
