Embolization of arteriovenous malformations of the brain: preliminary experience.

Author information

Department of Radiology, University Hospitals KU Leuven, Belgium.


Transcatheter embolization was performed in 8 young patients (mean age 24.5 years) with intracerebral arteriovenous malformations. In total 12 arteries were embolized in 10 sessions. Clinical complaints of the patients included epilepsy in 4, sudden coma in 3 and severe sudden neurological deficit in 1. Intracerebral hemorrhage was documented in 4 patients and subarachnoid hemorrhage in 1. In all patients, prior to embolization a superselective Wada-test was performed under wake-up anesthesia. Embolization was performed with a mixture of acrylic glue and lipiodol. In one patient a detachable balloon was added. In 6 patients embolization of all the feeding arteries was possible, with total obliteration of the arteriovenous malformations in 4 and subtotal embolization (> 90%) in 2. In 2 patients reduction of the size of the arteriovenous malformation by one third was followed by total surgical removal of the lesion. In 1 patient reflux of the embolization material in the anterior choroidal artery caused severe neurological deficit with good clinical recuperation.
