Abstract

From July 1988 through November 1991, 26 patients with inoperable arteriovenous malformations were treated with 6 MV linear accelerator at the Kangnam St. Mary's Hospital, Catholic University Medical College. There were 5 females and 21 males with median age of 29 years (range: 6~63 years) and median follow up times of 15 months (range: 4~40 months). The arteriovenous malformation volumes treated ranged from 1 cm diameter to 3.5 cm rectangular size. The prescribed doses at the isocenter varied from 15 to 30 Gy and were given as a single fraction. To date, all patients performed follow-up not only clinically but also through CT or angiography based radiologic modalities every 6 month. A complete obliteration was achieved in 6 (23%) and partial obliteration in 8 (31%) and no change in 1 (4%). We observed 14 (54%) responsiveness of arteriovenous malformations after radiosurgery by 2 years afterward. Whereas, the decision of the remaining 11 (42%) patients was considered too early to expect the therapeutic response following radiosurgery. No complications through treatment related were observed, yet. Our initial outcome in these first 25 patients with arteriovenous malformations is recommended further follow-up.
