Experiences in the Endovascular treatment of Cerebral Arteriovenous Angiomas

AbstractPercutaneous superselective balloon catheterization for the treatment of large cerebral arteriovenous malformations, for which direct operation is infeasible, is described. Both a detachable balloon technique and a «calibrated leak» free embolization have been applied, based on a new hardening silicone material elaborated by the authors. The experiences of operations performed since 1978 are represented by four selected case studies.
