Research progress in embolization treatment for cerebral arteriovenous malformations via transvenous approach / 介入放射学杂志

ABSTRACT

Clinically,arteriovenous malformations (AVM) is a common intracranial vascular disease.Traditional treatments for cerebral AVM include microsurgical resection,endovascular embolization and radiotherapy.However,there are some unusual AVM lesions that are difficult to be cured by traditional methods.Multiple case reports that have been published recently indicate that embolization therapy via transvenous approach is very effective for these unusual AVM lesions,especially for small hemorrhagic AVMs.These lesions often have single vein drainage and are located at deep cerebral function area.with their blood supply being from fine arteries.This paper aims to review the existing literature and to make a summary about the indications,method of operation,risks and prevention,etc.of embolization therapy via transvenous approach for cerebral AVM.
