[Transcatheter injection of silk particulates and line segments in the treatment of cerebral arteriovenous malformations].
The treatment of cerebral arteriovenous malformations (AVM) is difficult in neurosurgery. In recent years, intravascular treatment has been used with embolic material of IBCA or NBCA. We treated 51 patients by injecting silk particulates and line segments. Forty-eight of them were cured and 3 died from hemorrhage of malformed angiorrhexis: intraoperation (1), 14th day postoperation (1), and obstructive hydrocephalus complicated by intracranial infection after shunt (1). Silk particulates and line segments, which are safe, reliable, and inexpensive can be used instead of IBCA and NBCA. Intracranial AVM, especially in the recesses and domain may be treated operatively by intravascular embolization, It is important that microcatheter should be flow-guided into the deformed vascular mass of intracranial arteries.
