Cerebellar Arteriovenous Malformation Treatment
see also Posterior Fossa Arteriovenous Malformation Treatment.
In light of the unique natural history and angioarchitectural characteristics of cerebellar arteriovenous malformation, their management is distinct from supratentorial arteriovenous malformation counterparts, requiring a more aggressive treatment strategy.
Surgery
Emergency microsurgery is effective in the treatment of ruptured cerebellar AVM 1).
Approaches
Occipital transtentorial approach is a valuable approach for specific superior vermian, superomedian cerebellar, and tectal AVMs. Detailed assessment of angiographic features may however preclude its safety as a unique treatment plan, and complementary or alternative therapeutic options should be considered 2) 3).
Radiosurgery
Gamma knife radiosurgery for arteriovenous malformation
Radiosurgery is an effective treatment modality for Cerebellar Arteriovenous Malformation with relatively limited adverse events. Infratentorial location did not affect radiosurgery outcomes 4). Proved to be most effective for patients with smaller and previously nonembolized cerebellar malformations. Hemorrhage during the latency period occurred at a rate of 2.0% per year until obliteration occurred 5).
