E-180 Perforator vessel embolization for galenic arteriovenous malformation as a safe and feasible therapy

ConclusionWe have found that ThP and AchA embolization are feasible and effective means for achieving cure of VOGM and tectal/thalamic AVM. We report favorable, post-procedural outcomes in the majority of our patients; however, as with any embolization within the thalamic region of the brain, we maintain that caution should always be used due to the risk of stroke which we observed in one of our patients. If there is any doubt as to the safety of a given embolization, provocative testing with neuromonitoring is performed. In the case of the patient who experienced a post-procedural stroke, neuromonitoring was performed and still MEP/SEP waves were maintained after injection of amytal and lidocaine. To improve the safety of ThP and AchA embolization, we perform intraoperative neurophysiological monitoring of MEP and SEP with sodium amytal and lidocaine. We intend to expand this practice beyond VOGM and tectal/thalamic AVM into other eloquent AVMs as we have seen great success in our own clinic and in the literature.Disclosures M. Bazil: None. T.
