We describe a patient with traumatic carotid-cavernous fistula (CCF), subsequently developing contralateral extensive hemorrhagic venous infarction from retrograde venous reflux into the opposite basal vein of Rosenthal. A 54-year-old woman was involved in a motor vehicle accident and sustained severe traumatic brain injury. Two months later, she developed bilateral proptosis and audible bruit. Magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) of the brain demonstrated the right direct CCF...

Purpose: Carotid cavernous sinus ectasia is a rare cause of abducens nerve palsy. Observation: We present a case of severe unilateral progressive esotropia resulting from cavernous sinus carotid vascular ectasia in a 67 y/o female. She had progressive esotropia over the years with no neuroimaging despite having regular ophthalmic care. Magnetic resonance imaging determined the etiology of her chronic severe esotropia. Conclusion and importance: Carotid cavernous sinus ectasia should be considered in the differential of severe progressive unilateral abducens nerve palsy...

OBJECTIVE The transpterygoid extension of the endoscopic endonasal approach provides exposure of the petrous apex, Meckel's cave, paraclival area, and the infratemporal fossa. Safe and efficient localization of the lacerum segment of the internal carotid artery (ICA) is a crucial part of such exposure. The aim of this study is to introduce a novel landmark for localization of the lacerum ICA. METHODS Ten cadaveric heads were prepared for transnasal endoscopic dissection. The floor of the sphenoid sinus was drilled to expose an extension of the pharyngobasilar fascia between the sphenoid floor and the pterygoid process (the pterygoclival ligament)...

Patients with previous surgery of the carotids or significant stenosis are not included in the study populations of baroreceptor activation therapy. In this case report about a 78-year-old woman with implantation of a baroreceptor activation therapy system two decades after bilateral thrombendarterectomy, control of hypertensive dysregulation could be observed even 20 months after implantation. Successful modulation of the baroreceptors requires intact adventitial tissue near the carotid sinus. In our case with previous longitudinal incision and patch angioplasty, the nerval innervation had been preserved...

A healthy 51-year-old female presented with a spontaneous direct carotid-cavernous sinus fistula associated with a persistent primitive trigeminal artery. She had no history of connective tissue or cerebrovascular disorders or significant head trauma. This is a rare lesion with only 18 previously reported cases. It had similar clinical presentation and imaging appearance to a high-flow direct carotid-cavernous fistula and was uncovered after successful trans-venous coil embolisation of the fistula. It therefore needs to be considered in cases of direct carotid-cavernous fistula without history of trauma...

PURPOSE OF REVIEW: Most hypertension devices have been designed to interrupt or modify the sympathetic nervous system, which seems to be unbalanced in hypertension. Carotid baroreceptors play a pivotal role in maintaining adrenergic balance via a direct feedback interface and would be an exceptional target for intervention. The purpose of this review is to define the role of the baroreceptor in hypertension, to examine device-based therapies targeting the baroreflex and to explore future promises of endovascular baroreflex amplification (EBA)...

INTRODUCTION: Sixth nerve palsy is a common complication of endovascular treatment for carotid-cavernous fistulas (CCF). Two hypotheses are evoked: the spontaneous venous congestion into the cavernous sinus (CS), and the direct compression of the nerve by the embolic agent into the CS. Nevertheless, the evidence is still uncertain. Knowing the vicinity of the sixth nerve with the inferior petrosal sinus (IPS) in the Dorello's canal, we hypothesized that the recanalization of the IPS increased the risk of nerve damage...

Tolosa Hunt syndrome (THS) is characterized by painful ophthalmoplegia secondary to idiopathic granulomatous inflammation of the cavernous sinus. The characteristic finding on MRI is an enhancing T1 isointense and T2 hypo- or hyperintense cavernous sinus mass lesion, which may result in focal narrowing of the ipsilateral internal carotid artery. Although the incidence is quite rare, it is a common diagnostic consideration in cases that present with multiple cranial neuropathies. However, the differential diagnosis for a unilateral cavernous sinus lesion in adults is broad and includes neoplastic, inflammatory (such as sarcoidosis and immunoglobulin G4-related disease [IgG4-RD]), infectious etiologies (such as syphilis and leprosy), as well as vascular lesions...
