Orbitocranial Zygomatic Approach for Upper Basilar Artery Aneurysms
Orbitocranial Zygomatic Approach for Upper Basilar Artery Aneurysms Antonio Bernardo and Philip E. Stieg Abstract Aneurysms arising from the basilar apex are perhaps the most technically challenging aneurysms to treat…
Vertebral Confluence and Midbasilar Aneurysms Including Transpetrosal Approach
Vertebral confluence and midbasilar aneurysms are uncommon but surgically challenging lesions due in large part to the ventral location of pathology in the posterior fossa and the important downstream territory…
Spinal Vascular Malformations
Patient Selection Treatment of patients with spinal arteriovenous malformations (AVMs) carries a risk of paraplegia or quadriplegia. Therefore, before treatment is recommended, the natural history of the lesion must be…
Subtemporal and Pretemporal Approaches for Basilar and Posterior Cerebral Artery neurysms
Patient Selection Aneurysms at the distal third of the basilar artery including the basilar artery bifurcation and the origin of the superior cerebellar artery from the basilar artery and less…
Posterior Fossa Arteriovenous Malformations
Posterior fossa arteriovenous malformations (AVMs) comprise about 12% of all brain AVMs. About 70% present with hemorrhage into the brain parenchyma, the subarachnoid space, and/or the ventricular system. Current treatment…
Transsylvian Transclinoidal and Transcavernous Approach for Basilar Bifurcation Aneurysms
Patient Selection 14.1.1 Indications for Surgery and Alternatives Options for treatment of basilar apex region aneurysms include surgical clipping or endovascular treatment with coils. The preference for endovascular treatment tends to…
Arteriovenous Malformations of the Basal Ganglia and Thalamus
Patient Selection The overall risk of hemorrhage for cerebral arteriovenous malformations (AVMs) is about 2 to 4% per year. 1 Annual rupture rates are lower for unruptured AVMs compared to…
