Resection of Right Frontal Arteriovenous Malformation: 3-Dimensional Operative Video
1Department of Neurosurgery, Clinical Neurosciences Center, University of Utah, Salt Lake City, Utah.
Abstract:
The video demonstrates resection of a Grade II Spetzler-Martin unruptured, medium-sized arteriovenous malformation (AVM). A young woman presented with headaches and seizures. The right frontal lesion measured 4.5 cm in largest dimension and had superficial venous drainage. Partial Onyx embolization, primarily of the anterior cerebral feeding arteries, was performed. Bone removal for exposure allowed identification of indentation from the large superficial draining vein. The video demonstrates careful microsurgical dissection on the AVM/brain interface, with selective interruption of feeding arteries circumferentially. The lesion was removed after ligation of the large superficial draining vein. Postoperative day 1 and 1-yr angiography demonstrated complete resection. The patient's symptoms abated after resection. This case is presented with a waiver of informed consent as per the Institutional Review Board.

Vector Operations
A vector multiplied by a scalar value is called scalar multiplication. The result obtained is a new vector with a different magnitude. If the scalar is positive, the direction of the vector remains the same, but if it is negative, the direction of the vector is reversed. For example, the product of the mass and velocity yields the momentum.

Reinforcement in operant conditioning can be positive or negative, both of which serve to increase the likelihood of a behavior. Positive...
