Pearls Advances in knowledge regarding the natural history of iAVMs and indications for surgery have enhanced patient selection for specific treatment modalities. Imaging modalities allow for precise determination of nidus size, intranidal aneurysm presence, and characterization of arterial feeders and…
Pearls Giant iAVMs are a rare entity. They can be symptomatic due to bleeding as well as through steal phenomena. Treatment is almost always multimodality, with an emphasis on mitigating bleeding risk and palliation of symptoms. Cure is rare. Giant…
Pearls Each individual technique for treating AVMs has its own risk profile, and while often overlapping, there are some differences. Surgery carries a risk of infection relating to the craniotomy, retraction injury, cerebral contusion, hemorrhage, seizure, and so on. Radiosurgery…
Pearls The risk of hemorrhage dictates neurosurgical intervention for iAVMs. Stereotactic radiosurgery (SRS) is utilized when microsurgical resection of an iAVM is not possible due to location, size, feeding vessels, or medical comorbidities that preclude resective surgery. Embolization is often…
