AbstractWe report a case of craniocervical junction dural arteriovenous fistula (dAVF) presented with myelopathy and normal pressure hydrocephalus, and was treated with hybrid approach of embolization and surgical disconnection. A 68-year-old gentleman presented with 1 year history of unsteady gait and sphincter disturbance. Magnetic resonance imaging (MRI) showed abnormally enlarged and tortuous vessels over right cerebellomedullary cistern. Digital subtraction angiogram (DSA) showed Cognard's type-V dAVF at craniocervical junction. Catheter embolization was performed via external carotid artery and finally surgical disconnection was done with far lateral approach (Fig. 1). Postoperative DSA showed no more arteriovenous shunting (Fig. 2). Clinically the patient improved after a course of rehabilitation. Dural AVF at craniocervical junction is rare and its clinical presentation can be highly variable from subarachnoid hemorrhage to brainstem dysfunction. Identification of the exact fistula site is essential in surgical planning. Surgery is effective and safe to achieve complete obliteration and good clinical outcome.1 2 3 4 5 6 The link to the video can be found at: https://youtu.be/xI48stSlWpY.

Abstract Dural arteriovenous fistulae at the craniocervical junction are rare. When present together with spinal and cranial venous reflux they can have an aggressive natural history with hemorrhage or progressive myelopathy from venous congestion. In this operative video we demonstrate key steps in the surgical ligation of a dural arteriovenous fistula supplied by meningeal branches of the V4 segment of the vertebral artery.  Informed consent was obtained. The patient was positioned prone with chin tucked. Utilizing a midline suboccipital craniotomy and removal of the arch of C1, the vertebral artery was identified at its V4 segment at it transitions from extra to intradural. The video illustrates how a midline approach can be used to access this lesion and a far lateral approach is not required to access the vertebral artery and its dural branches at the craniocervical junction. Division of the denticulate ligaments and mobilization of the spinal accessory nerve allows visualization of the proximal portion of the draining vein. Important anatomy in this region is demonstrated. The critical use of indocyanine green (ICG) dye is demonstrated as the first 2 clip applications were not proximal enough to obliterate the proximal draining vein and persistent early venous reflux was still seen on ICG. The importance of access to and obliteration of the proximal draining vein is shown. An intraoperative ICG and postoperative angiogram demonstrates complete occlusion of the dural arteriovenous fistula.  In this case the patient had minor sensory deficits postoperatively which were resolved by 6 wk postoperatively.

This video demonstrates the diagnosis and surgical ligation of a C1 dural arteriovenous fistula via a far lateral, transcondylar approach. The patient’s dural arteriovenous fistula was identified by MRI signal changes in the spinal cord and a cerebrospinal angiogram demonstrating an abnormal hypertrophied early venous drainage pattern suggestive of a C1 vessel origin. Indocyanine green was used to verify surgical treatment of the fistula intraoperatively. A postoperative angiogram and MR image demonstrate fistula occlusion and resolution of the spinal cord edema. Anatomic details and technical nuances of the approach are demonstrated.The video can be found here: https://youtu.be/zSd0vuov8xk.

Abstract This case is a 66-yr-old woman with a 2-mo history of left-sided tinnitus. Workup with magnetic resonance angiography showed early opacification of the left sigmoid sinus and internal jugular vein as well as asymmetric and abundant opacification of the left external carotid artery branches, suspicious for a dural arteriovenous fistula (dAVF). Diagnosis was confirmed with cerebral angiography, consistent with a left-sided Cognard type I dAVF.1 Initial treatment attempt was made with transarterial 6% ethylene-vinyl alcohol copolymer (Onyx 18) embolization of feeders from the occipital and middle meningeal arteries. However, embolization was not curative and there was a recurrence of a highly bothersome tinnitus 3 wk following treatment. Angiography redemonstrated the transverse sinus dAVF with new recruitment arising from several feeders, including the left external carotid artery, middle meningeal artery, and superficial temporal artery, now Cognard type IIa. Definitive treatment through a transvenous coil embolization provided permanent obliteration of the fistula without recrudescence of symptoms on follow-up. In this video, the authors discuss the nuances of treating a dAVF via a transvenous embolization. Patient consent was given prior to the procedure, and consent and approval for this operative video were waived because of the retrospective nature of this manuscript and the anonymized video material.

Neurenteric cysts are rare and benign lesions that consist of ectopic alimentary tissue residing in the central nervous system. They tend to occur most frequently in an intraspinal rather than intracranial location. Intracranial neurenteric cysts are a rare occurrence in the pediatric population. These lesions typically present as unilateral cystic structures in the lower cerebellopontine angle and craniocervical junction. To the authors' knowledge, there have been no reported cases of bilateral localization of intracranial neurenteric cysts. In this report, they present an unusual case of a 10-year-old girl who was found to have bilateral intracranial neurenteric cysts at the pontomedullary junction. The patient was successfully treated with staged, bilateral far-lateral transcondylar resection of the cysts. The authors also provide a brief overview of the literature describing intracranial neurenteric cysts in children.

A small arteriovenous malformation near the craniocervical junction with contributions from the anterior spinal artery was discovered in a young developmentally-delayed woman after she presented with altered mental status and evidence of subarachnoid hemorrhage. The malformation could not be completely treated with endovascular therapy, so it was resected through a far-lateral approach. This stereoscopic video demonstrates how to gain the exposure needed to address a lesion in this area. The video can be found here: http://youtu.be/ByjPGm_eXLc.

The article describes the clinical manifestations of dural arteriovenous fistula, which is an abnormal communication between the arteries of the dura mater and venous sinuses or cortical veins. Information on the etiology and pathogenesis of such malformation in domestic literature is limited to a few publications. Diagnosis is based on the identification of visual (pulsation of the earlobe) and acoustic phenomena in the patient, the presence of neuroimaging, in particular MR angiography, a shunt between the posterior auricular artery (branch of the external carotid artery) and the dural venous sinuses. The best treatment method is neurosurgical intervention using endovascular surgery.
