[Diagnosis and embolization of dural arteriovenous fistulae: report of 18 cases].
In the diagnosis and embolization of 18 patients with dural arteriovenous fistulae (DAVF), we found that they had subarachnoid hemorrhage, exophthalmos and craniocerebral murmur. Angiographically, DAVF was classified in to simple type (9 patients) and complex type (9). A total of 34 embolization procedures were performed in this group. solid particle embolization was used in 31 patients and IBCA embolization in 3. Seven patients were embolized once, 7 twice, 2 four times, and 1 five times. Among them, 7 patients were cured, 9 were improved, and in 1 recurred. DSA is importance in the diagnosis of DAVF. To embolize the entrance of fistulae is the key point of the treatment. This technique is safe and effective. Simple DAVF can be cured by intravascular embolization and the complex one can be cured or improved by multiple embolization.
