The most common etiology is a midbrain infarction caused by occlusion of the paramedian branches of the posterior cerebral artery or the perforating branches of the basilar bifurcation. Although there are many multiple brainstem strokes, it is uncommon to see this syndrome. Read More

Orbital Fractures With Concomitant Ocular Nerve Palsy: An Insidious and Potentially Misleading Association in Surgical Decision-Making.

J Oral Maxillofac Surg 2022 Mar 25. Epub 2022 Mar 25.

Head, Neuro-Ophthalmology and Strabology Unit, Department of Clinical Neurosciences, Division of Ophthalmology, University Hospital and Faculty of Medicine of Geneva, Genève, Switzerland.

Cavernous sinus dural arteriovenous fistula accessed through a straightened superficial temporal vein.

Surg Neurol Int 2021 30;12:634. Epub 2021 Dec 30.

Department of Neurosurgery, Nagoya City University Graduate School of Medical Sciences and Medical School, Nagoya, Aichi, Japan.

Background: Transvenous embolization through the inferior petrosal sinus (IPS) is the most common treatment procedure for cavernous sinus dural arteriovenous fistula (CSDAVF). When the IPS is inaccessible or the CSDAVF cannot be treated with transvenous embolization through the IPS, the superficial temporal vein (STV) is used as an alternative access route. However, the approach through the STV is often challenging because of its tortuous and abruptly angulated course. Read More
