OBJECT A @entity227 resulting from the management of an @entity2758 ( @entity2758 ) significantly impacts a @entity1 's quality of life. The present study was designed to investigate the clinical and radiological outcomes of stereotactic radiosurgery (SRS) performed for AVMs involving the postgeniculate visual pathway. METHODS In this retrospective single-institution analysis, the authors reviewed their experience with Gamma Knife surgery for postgeniculate visual pathway AVMs performed during the period between 1987 and 2009. RESULTS During the study interval, 171 @entity1 underwent SRS for AVMs in this region. Forty-one @entity1 (24%) had a @entity227 prior to SRS. The median target volume was 6.0 cm(3) (range 0.4-22 cm(3)), and 19 Gy (range 14-25 Gy) was the median margin dose. Obliteration of the @entity2758 was confirmed in 80 @entity1 after a single SRS procedure at a median follow-up of 74 months (range 5-297 months). The actuarial rate of total obliteration was 67% at 4 years. @entity2758 with a volume < 5 cm(3) had obliteration rates of 60% at 3 years and 79% at 4 years. The delivered margin dose proved significant given that 82% of @entity1 receiving >=  22 Gy had complete obliteration. The @entity2758 was completely obliterated in an additional 18 @entity1 after they underwent repeat SRS. At a median of 25 months (range 11-107 months) after SRS, 9 @entity1 developed new or worsened @entity227 . One @entity1 developed a complete homonymous @entity1805 , and 8 @entity1 developed @entity1805 . The actuarial risk of sustaining a new @entity227 was 3% at 3 years, 5% at 5 years, and 8% at 10 years. Fifteen @entity1 had @entity548 during the latency period, resulting in death in 9 of the @entity1 . The annual @entity548 rate during the latency interval was 2%, and no @entity548 occurred after confirmed obliteration. CONCLUSIONS Despite an overall treatment mortality of 5%, related to latency interval @entity548 , SRS was associated with only a 5.6% risk of new @entity227 and a final obliteration rate close to 80% in @entity1 with AVMs of the postgeniculate visual pathway.
