Purpose: To establish the role of stereotactic radiosurgery (SRS) for the treatment of patients with angiographically occult vascular malformation (AOVM).
Materials and Methods: Eleven patients (12 lesions) with AOVM were treated with
linear acceleratorbased SRS between February 1995 and December 1999. A magnetic
resonance imaging of each patients showed well-circumscribed vascular lesion with
reticulated core of heterogeneous signal intensity and peripheral rim of low signal
intensity. SRS were performed with the median peripheral dose of 16 Gy (range 13~15).
A single isocenter was used with median collimator size of 14 mm (rang 8~20) diameter.
Results: With a median follow-up period of 42 months (range 12~56), rebleeding
occurred in 3 AOVMs at 5, 6 and 12 months after SRS but no further bleeding did.
Two patients experienced radiation-induced necrosis associated with permanent
neurologic deficit and one patient showed transient edema of increased T2 signal
intensity
Conclusion: SRS may be effective for the prevention of rebleeding in AOVM located in
surgically inaccessible region of the brain. Careful consideration should be need in the
decision of case selection and dose prescription because the incidence of
radiation-induced complications is too high to be accepted.
