Pial Dissection
5 Pial Dissection Arterial Fronts Previous phases of dissection—arteriovenous malformation (AVM) exposure, subarachnoid approach, definition of draining veins, and the identification of feeding arteries—are mere saber-rattling. The AVM is surveyed…
Subarachnoid Dissection
2 Subarachnoid Dissection Reconnaissance Subarachnoid dissection is the calm before the clash, when the arteriovenous malformation (AVM) is approached, encountered, and surveyed under the microscope without salvo. The labyrinth of…
Anterior Communicating Artery Aneurysms
16 Anterior Communicating Artery Aneurysms Microsurgical Anatomy The A1 segment begins at the terminal bifurcation of the internal carotid artery (ICA) and ends at the anterior communicating artery (ACoA) (Fig….
Ophthalmic Artery Aneurysms
17 Ophthalmic Artery Aneurysms Microsurgical Anatomy Arterial Anatomy Ophthalmic artery (OphA) aneurysms originate from the ophthalmic segment of the internal carotid artery (ICA). Simple classifications such as Rhoton’s describe only…
Posterior Inferior Cerebellar Artery Aneurysms
20 Posterior Inferior Cerebellar Artery Aneurysms Microsurgical Anatomy Vertebral artery originates from the subclavian artery, ascends through the transverse processes of the upper six cervical vertebrae, swings behind the lateral…
Middle Cerebral Artery Aneurysms
15 Middle Cerebral Artery Aneurysms Microsurgical Anatomy Segmental anatomy is defined by the middle cerebral artery’s (MCA) complex curvature rather than its branches. The M1 segment begins at the terminal…
