Embolic materials intracranial aneurysm

Abstract This chapter focuses on the vascular applications of injectable biomatetials. Two clinically relevant vascular conditions, cerebral arteriovenous malformations and intracranial aneurysm, will be discussed in terms of endovascular embolization. This chapter then outlines available embolic materials used to treat each condition, as well as highlighting new injectable biomaterials developed for embolization purposes. 

Embolic materials for both intracranial AVMs and aneurysms have come a long way since the first endovascular embolization procedure was carried out. Much advancement to this branch of neurosurgery came about because of an emphasis on development of equipment that was better suited to endovascular techniques. Some of these inventions include flow-directed microcatheters, endovascular balloons, and re-designed stents. Owing to a greater capacity to perform endovascular techniques with suitable equipment, the development of better embolic materials has followed. Now, there are a variety of techniques and materials that endovascular neurosurgeons have at their disposal, all of which provide a variety of benefits, yet have considerable drawbacks. Efforts are always being made to improve current materials and techniques, as well as to...
