Results of 55 AVM Cases Treated by Embolization and/or Surgery.

SUMMARY: In order to build a data base for future comparison, we summarized the treatment results of cerebral arteriovenous malformation (AVM) patients in our hospital. Fifty five AVM patients who had been treated at Nagoya University Hospital from 1988 to 1995 were enrolled in the study. The patient characteristics were nearly the same as other reported series. Trend of treatment modality was changing in this period and embolization was increasing in its role. Karnofsky score was used to follow the patients' clinical status. It was useful to assess pretreatment clinical status and post treatment status. The results showed the improvement of the embolization procedure.
