Selective Arterial Embolization of the Large, Deep-seated Arteriovenous Malformations

ABSTRACT

Selective arterial embolization can reduce the size and pressure whtihin the nidus of the arteriovenous malformations(AVMS) and diminish the number of feeding pedicles, making subsequent surgical excision technically easier and safer, especially in those AVM patients whose lesions are judged to be inoperable or respectable with major risk. Authors have successfully and repeatedly performed selective arterial embolizations with polyvinyl alcoholfoam(PVA foam) and isobutyl-2-cyanoacrylate(IBCA) to a large AVM at the left basal ganglia, thalamus and lateral ventricles, and a large cortical AVM near right motor strip.
