Operative cannulation of the superior ophthalmic vein for embolization of cavernous sinus dural arteriovenous fistulas: surgical techniques and clinical outcome.

World Neurosurg 2022 Jun 21. Epub 2022 Jun 21.

Division of neurosurgery, Department of surgery, Faculty of medicine, Thammasat University Hospital, Pathum Thani, 12120, Thailand.

Background: Endovascular therapy is the first-line treatment for the cavernous sinus dural arteriovenous fistulas (CS-DAVF), particularly transvenous embolization. This study aimed to assess the trans-superior ophthalmic vein approach to embolization for its safety, efficacy, and viability as a first-line treatment in selected patients, with a description of the microsurgical and endovascular techniques.

Methods: We retrospectively reviewed patients with CS-DAVF treated using the direct SOV approach with n-butyl cyanoacrylate (n-BCA) and coils as the main embolic materials from 2015 to 2021. Read More

Bilateral Carotid-Cavernous Fistula: A Diagnostic and Therapeutic Challenge.

J Investig Med High Impact Case Rep 2022 Jan-Dec;10:23247096221094181

University of Arkansas for Medical Sciences, Little Rock, USA.

Carotid-cavernous fistula (CCF) is an aberrant communication between the main trunk or branches of carotid artery and the cavernous sinus. Most of the cases of CCF occur following head trauma, but congenital and spontaneous cases have been reported. We report an interesting case of bilateral CCF with no history of trauma, thus most likely spontaneous form. Read More

Front Surg 2022 10;9:895233. Epub 2022 May 10.

Department of Neurological Surgery, Nippon Medical School, Tokyo, Japan.

Background: Injury to the internal carotid artery (ICA) during endoscopic transsphenoidal surgery (ETSS) is a serious complication with a risk of mortality. ICA injury during ETSS usually occurs during intrasellar manipulations and rarely occurs in the extrasellar portion. Several hemostatic procedures have been proposed for ICA injury in the intrasellar portion, whereas hemostatic methods for ICA injury in the extrasellar portion, where the ICA is surrounded by bone structures, are less well known.

Balloon-Assisted Roadmap Technique to Enable Flow Diversion of a High-Flow Direct Carotid-Cavernous Fistula.

J Stroke Cerebrovasc Dis 2022 Jan 22;31(1):106180. Epub 2021 Nov 22.

Penn State Health Milton S. Hershey Medical Center, Department of Neurosurgery, 500 University Dr. Hershey, PA, 17033, USA. Electronic address:

Background: The use of flow diverters as a first-line treatment for direct carotid cavernous fistula (CCF) is a relatively new approach in the neurointerventional field which allows obliteration of the fistula with less mass effect from coils in the cavernous sinus. Safe and successful deployment of a flow diverter requires adequate imaging of the parent vessel, which may be challenging in the setting of high-flow CCF without antegrade flow.

Objective: To facilitate adequate parent vessel imaging in the setting of high-flow CCF to enable the safe development of a flow diverter device. Read More
