Abstract
Neurointerventional radiology has many applications in the skull base. We focus on preoperative embolization to hypervascular tumors and embolization of the vascular lesion, in a hope to keep in-depth discussion. The former section discusses preoperative embolization to hypervascular tumours. The goals of the preoperative embolization are to devascularize the tumour vessel and to decrease surgical blood loss. The basic principle is emphasized in this part. Dangerous intracranial-extracranial collateral, in terms of functional anatomy, is introduced. Embolic agents and embolization methods are comprehensively discussed. Illustrations with the juvenile angiofibroma and paraganglioma are presented. In the section on vascular lesions, we discuss the dural arteriovenous fistula and carotid cavernous fistula. The goal of embolization treatment is usually disease cure or alteration of natural history. The pathophysiology, classification, and clinical presentations of the entities are briefly reviewed. Embolization approaches and common techniques are discussed with updated evidence. Other issues, including postprocedural care and alternative treatments, are also covered in this section.
