Awake Microsurgical Resection for a Precentral Gyrus Arteriovenous Malformation-Three-Dimensional Video and Anatomic Landmarks.

Arteriovenous malformations (AVMs) are complex, heterogeneous, and uncommon neurovascular disorders that frequently manifest in young adults. Parenchymal AVMs are thought to be congenital, but this has been recently questioned in the literature. AVMs can change over time and cause focal neurological signs or neurocognitive deficits.

Microsurgical Treatment for a Cerebral Arteriovenous Malformation of the Central Sulcus.

Arteriovenous malformations (AVMs) are congenital neurovascular disorders frequently manifested in young adults. The clinical presentation is variable and depends on its location, size, and ability to steal flow from adjacent areas, but it depends mainly on the occurrence of bleeding. The treatment of these lesions when located in eloquent areas, especially around the central sulcus, is controversial.

Microsurgical Treatment for a Ruptured Posterior Inferior Cerebellar Artery Aneurysm: A 3-Dimensional Surgical Video and Anatomic Landmarks Review.

Aneurysms are the most frequent issue for the posterior inferior cerebellar artery (PICA). PICA aneurysms account for 1.4% to 4.

Awake Microsurgical Resection for Optochiasmatic Cavernous Malformation.

Cavernous malformations (CM) affect approximately 0.5% of the population, with only a limited portion being located in the optic nerve and chiasma. The clinical presentation is determined by their locations.

Microsurgical Treatment for Posthemorrhagic Cavernoma of Frontal Lobe Coexisting with Unruptured Ipsilateral Middle Cerebral Artery Aneurysm.

Cerebral cavernous malformations, also known as cavernomas, are vascular abnormalities of the brain that are clinically associated with a variety of neurologic symptoms that may include hemorrhagic strokes. They are the most common vascular abnormality, representing 10%-25% of all vascular malformations. Lesions associated with cavernomas include developmental venous anomalies, capillary telangiectasias, and other vascular malformations but not intracranial aneurysms.
