Abstract
CT and MRI obtained after complete nidus obliteration had been angiographically confirmed were reviewed in nine patients who had undergone treatment with a gamma knife arteriovenous malformations (AVMs). The patients ranged in age from 9 to 54 years (mean 23 years). The period between angiographic confirmation of nidus obliteration and these most recent examinations was 18–24 months (mean 34 months). These results disclosed that radiosurgery-induced changes in a nidus may continue for several years after angiography has shown complete AVM obliteration. These late changes can be considered to involve further obliteration of the remaining or recanalising vessels, reflecting an ongoing process from coagulation necrosis to liquefaction necrosis.
