Superselective endovascular embolization of brain arteriovenous malformations [BAVMS]

ABSTRACT

The authors describe their experience with fifteen BAVMs treated by superselective endovascular embolization alone. Five patients presented with intracranial hemorrhage; four with intractable seizures; three with severe headaches; two with progressive neurological deficit and one with diplopia. In 9 cases, obliteration of 50- 75% of the AVM nidus was achieved and in in 3 cases this precentage increased to between 75 and 90%. Complete obliteration of AVM nidus was achieved in two cases. In only a single patient there was no significant obliteration at all. No mortality related to embolization procedure with only negligible percentage of morbidity being reversible. Short term [3ws]. outcome showed improvement in almost all the cases. Only in a single patient with massive cerebellar hemorrhage death occurred. Endovascular embolization of brain arteries malformations [BAVMs] using microcatheters a liquid acrylic material is a useful addition to the methods of treating and controlling such a complex problem:
