Microsurgical Treatment of Ruptured Spetzler-Martin Grade 3 Right Hippocampal Arteriovenous Malformation: 3-Dimensional Operative Video.
We present a 14-yr-old male with a history of traumatic brain injury in March 2016, secondary to clonic tonic generalized seizures. CT scan showed hemorrhage at mesial temporal region in the body of right hippocampus, intraventricular hemorrhage at the level of lateral ventricles (right and left side) and fourth ventricle. After this the patient presented with pulsating right temporal headache of high intensity (VAS 10/10) that improved with common analgesics, dizziness, and clonic tonic generalized seizures despite taking Phenobarbital 100 mg/24 h. ⋯ Postoperatively, the patient was without medical complications. We present a 3-dimensional video of the microsurgical treatment for right hippocampal AVM performed through a trans-T2 approach. The patient signed the Institutional Consent Form, which allows the use of his/her images and videos for any type of medical publications in conferences and/or scientific articles.

Left Retrosigmoid Craniotomy for Resection of Cavernous Malformation: 2-Dimensional Operative Video.
Pontine cavernous malformations are highly morbid lesions that require thorough preoperative planning of the surgical approach and meticulous surgical technique to successfully remove. The patient in this case has a large pontine cavernous malformation coming to the parenchymal surface along the pontine-middle cerebellar peduncle interface. The depth of the surgical field and narrow trajectory of approach require use of lighted suction, lighted bipolar forceps, and stereotactic neuronavigation to successfully locate and remove the entire lesion. ⋯ The patient gave informed consent for surgery and video recording. Institutional review board approval was deemed unnecessary. Used with permission from Barrow Neurological Institute, Phoenix, Arizona.

Overcoming Daunting Challenges of Clipping of Paraclinoid Carotid-Ophthalmic and Superior Hypophyseal Artery Aneurysms: 2-Dimensional Operative Video.
This surgical video emphasizes the nuances that needed to overcome daunting challenges of clipping of paraclinoid carotidophthalmic and superior hypophyseal artery (SHA) aneurysms. To avoid hazardous manipulations, scarifying the ipsilateral SHA under visual evoked potential (VEP) guidance can be done without risk of postoperative visual decline. This technique is associated with better visual outcome.1 A 66-yr-old woman presented with gradually enlarging right paraclinoid carotidophthalmic and SHA aneurysms. ⋯ The postoperative course was uneventful. There was no evidence of postoperative visual disturbances. The patient has consented to the submission of the case report to the journal.

Single Vessel Double Anastomosis for Flow Augmentation - A Novel Technique for Direct Extracranial to Intracranial Bypass Surgery.
A double anastomosis using a single superficial temporal artery (STA) donor branch for both a proximal side-to-side (S2S) and a distal end-to-side anastomosis is a novel direct bypass technique for use in selected patients necessitating flow augmentation. ⋯ SVDA is a novel technique that can be advantageous for selected cases of extracranial-to-intracranial bypass. Expertise in bypass procedures is a necessary prerequisite. Graft patency rates and complications appear comparable to other bypass techniques.

Two-Stage Revascularization and Clip Reconstruction of a Giant Ophthalmic Artery Aneurysm: 3-Dimensional Operative Video.
Ophthalmic segment aneurysms (OSAs) are technically challenging lesions with a wide-neck morphology and proximity to the optic nerve. Revascularization and aneurysm trapping are occasionally needed to manage unclippable OSAs. Microsurgical treatment requires anterior clinoidectomy, optic strut drilling, and proximal/distal dural ring dissection for adequate exposure. ⋯ Although OSAs are preferentially treated with flow diversion, giant OSAs with significant mass effect may necessitate microsurgical clipping or trapping with decompressive thrombectomy. This case demonstrates that proximal clip occlusion may not be sufficient for aneurysm thrombosis and rupture prevention. Used with permission from Barrow Neurological Institute, Phoenix, Arizona.
