18 Patient Selection Judicious patient selection is essential to avoid surgical complications and poor neurologic outcomes with microsurgical resection of brain arteriovenous malformations (AVMs); it is the secret to success….

7 Ependymal/Deep Dissection The Dark Side “Ependymal” dissection may be a confusing term because many arteriovenous malformations (AVMs) do not reach a ventricle, but it is meant to describe the…

1 Arteriovenous Malformation Exposure The Box Arteriovenous malformations (AVMs) come in many shapes: spheres, ellipses, cylinders, and, classically, cones. The cone is based on the cortical surface and tapers to…

3 Draining Veins Absolute Preservation The most basic and important tenet of arteriovenous malformation (AVM) surgery is that the draining vein must be preserved until the very end of the…

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…

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…
