Indications • Basilar apex aneurysms include ruptured or unruptured basilar bifurcation aneurysms, superior cerebellar artery (SCA) aneurysms, and P1 posterior cerebral artery (PCA) aneurysms. • Patients who are young and…
Indications Ruptured Aneurysm • All ruptured paraclinoid aneurysms with subarachnoid hemorrhage as the presentation need to be treated. Multiple and bilateral aneurysms are more common among this group of aneurysms….
Indications • Clipping of distal anterior cerebral artery (DACA) aneurysms has a long-lasting effect; rerupture of previously clipped aneurysm is very rare. • DACA aneurysms are usually small, with a…
Indications • We prefer surgical clipping of most ruptured and unruptured middle cerebral artery (MCA) aneurysms because of the accessibility of their location and the relatively low morbidity and durability…
Indications Absolute • Subarachnoid hemorrhage with intraparenchymal hemorrhage requiring emergent evacuation • Subarachnoid hemorrhage with anterior communicating artery (Acomm) aneurysm not repairable by endovascular coiling Strong • Large aneurysm (≥10…
Indications Absolute • Subarachnoid hemorrhage with intraparenchymal hemorrhage requiring emergent evacuation • Subarachnoid hemorrhage with posterior communicating artery (Pcomm) aneurysm not repairable by endovascular coiling Strong • Large aneurysm (≥10…
Indications • The retrolabyrinthine approach is a hearing-preserving presigmoid approach that uses a mastoidectomy and skeletonization of the sigmoid sinus to expose the presigmoid dura behind the semicircular canals. •…
Indications • The middle fossa approach is a largely extradural approach to the bony structures that make up the floor of the middle fossa. • Although the convex floor of…
Indications • Transsylvian approaches enter the parasellar cisterns on a superior-to-inferior trajectory, forcing the surgeon to work past the carotid artery through the opticocarotid or carotid-oculomotor triangles to access this…
Indications • The suboccipital approach with C1 laminectomy provides adequate visualization of approximately 270 degrees of the circumference around the medulla. This approach does not provide safe access to the…
