Surgical Problems in Partially Embolized Angiomas
Five years ago, we changed our policy regarding the treatment of cerebral arteriovenous malformations (AVMs) from a purely surgical technique to a combined procedure with preoperative embolization and operation. Since then, the number of operations on AVMs has decreased. One reason for this is the fact that some AVMs are still under neuroradiological treatment; another may be that in some cases the neuroradiologist was able to completely occlude the malformation. One further reason could be the lack of information on how effectively embolized but still active AVMs can be surgically treated. This article is intended to contribute to some aspects of the problems encountered during surgery on embolized AVMs and to the final result after surgical removal of an incompletely embolized AVM.
