Multiple Intracerebral Arteriovenous Malformations in Deep Structure

—Case Report—

抄録

The authors describe a case of multiple intracerebral arteriovenous malformations (AVMs) in a 23-year-old male with two distinct, deep-seated AVMs. One was located in the left basal ganglia, which had bled twice, and the other in the splenium. They were removed separately. He recovered satisfactorily with only a mild dysphasia. The authors emphasize that the therapeutic principle for multiple AVMs is the same as that for a solitary AVM. Multiplicity alone does not dictate the operability. Dissection just adjacent to the nidus and direct coagulation of an AVM are the indicated techniques, especially in cases of deep-seated AVMs in order to reduce postoperative neurological deficit.
