Interventional Therapy of Cerebrovascular Disease Mechanical Embolic Materials

Intravascular embolism has become the major means for treating intracranial aneurysm, cerebral arteriovenous malformation and arteriovenous fistula. With the development of mechanical embolic materials, especially mechanical detachable tungsten filament micro spiral, guglielmi datacbcble micro coil and other controlled micro spiral techniques, intracranial aneurysms can almost achieve the same effect of surgical clipping. However, all kinds of mechanical embolic materials have their advantages and disadvantages in clinical application. In order to meet the needs of different parts, different nature of the disease, the development and application of new materials in the endovascular treatment field has been carried out. The mechanical embolic materials are of two types: micro spirals and detachable balloon. The report briefly introduces the types and efficacy of mechanical embolization materials.
