Endovascular occlusion via the transvenous route is the favored treatment for indirect carotid-cavernous fistulas (CCFs). However, transarterial embolization can be used as an alternative method in patients with an inaccessible venous route. The authors present the case of a 49-year-old woman with a 2-month history of chemosis and proptosis in her right eye. Angiography demonstrated a Barrow Type D CCF. Transarterial Onyx embolization through the accessory meningeal artery was performed after an unsuccessful transvenous approach...

A 58-year-old man presented with slowly progressive chemosis, exophthalmos, and blepharedema of the left eye. Digital subtraction angiography revealed multiple dural arteriovenous fistulas(dAVFs)involving the bilateral tentorium, superior sagittal sinus, and right frontal convexity. In addition, occlusion of the left cavernous sinus and left sigmoid sinus were observed, which could lead to venous hypertension and might be associated with the occurrence of multiple dAVFs. Along with the congestion of the left ophthalmic vein, increased intracranial pressure due to the left tentorial dAVF with cortical venous reflux could have caused the left eye symptoms; therefore, the tentorial lesion was treated first...

We investigated endovascular treatment for 10 mm or larger aneurysms in the internal carotid artery (IC), including the cavernous portion, the paraclinoid portion, and the posterior communication artery (PC). Between 2011 and 2014 at our hospital, there were 35 cases of aneurysms that were 10 mm or larger in the carotid artery. We analyzed these 35 cases retrospectively based on the size and location of the aneurysms, method of treatment, number of coils implanted, use of a stent, complications, rupture after treatment, ophthalmologic symptoms, and need for re-treatment...

BACKGROUND: The efficacy for the treatment of large carotid cavernous aneurysms (CCAs) was compared between conventional endovascular treatments, stent-assisted coiling (SAC), parent artery occlusion (PAO), and the flow diverter (FD). METHODS: Between January 2001 and December 2015, 49 patients with large, broad-necked, unruptured CCA underwent endovascular treatment at our institution. We performed PAO in 22 patients, SAC in 18 patients, and FD in 9 patients. Safety and efficacy were assessed in all patients by periodic clinical and radiological examinations during a 6-month follow-up...

An isolated unilateral abducens nerve palsy or headache alone usually yields negative findings on neuroimages. The authors report an individual with right abducens nerve palsy who developed a sudden, persistent headache on the right side. Magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) revealed a giant aneurysm of the cavernous carotid artery that was located along the course of the right abducens nerve. The findings in this case of isolated abducens nerve palsy suggest that headaches should be considered as important signs for intracranial aneurysmal lesions...

The carotid-cavernous fistula (CCF) is a rare complication in patients victimized by craniofacial trauma. It involves multidisciplinary medical action. Owing to its potential complications, it is essential that maxillofacial surgery and neurosurgery specialists diagnose this condition so that appropriate treatment can be performed. The authors present a report of a case 11 years after the surgery.

Diffusion-weighted imaging (DWI) has transformed the radiological assessment of a variety of cerebral pathologies, in particular acute stroke. In neuroimaging studies, DWI can also be used to evaluate pathology outside the brain parenchyma, although it is sometimes underutilized for this purpose. In this pictorial review, the principles of DWI are outlined, and 13 cases of abnormal diffusion outside the brain parenchyma are illustrated in order to show DWI as a useful sequence for the evaluation of the following recommended review areas: the dural venous sinuses, internal carotid arteries, meninges, ventricles, cavernous sinus and orbits, skull base and lymph nodes...

Carotid-cavernous fistulas (CCFs) pose an anatomically and physiologically challenging problem for clinicians. The most common method of treatment for these lesions is transvenous endovascular embolization via the inferior petrosal sinus or the facial vein. When transvenous access is not possible, an alternate approach must be devised. We describe a case example with bilateral Barrow Type B CCFs, which were inaccessible using the traditional transvenous approach. Hence, a direct transorbital approach, performed under fluoroscopic guidance, was employed to successfully obliterate the CCF...

Traumatic carotid cavernous fistula may occur as a complication of endovascular treatment of acute stroke. We report 3 cases of such lesions. All patients were initially managed conservatively. Two patients have remained asymptomatic. One patient became symptomatic with right eye proptosis, chemosis, and right lateral gaze diplopia 3 weeks post thrombectomy. He underwent endovascular embolization via transfemoral transvenous approach via the inferior ophthalmic vein.

This report describes a case of a serpentine fusiform aneurysm of the internal carotid artery in a patient who presented with visual disturbances. The serpentine aneurysm was treated successfully by coil trapping and occlusion of the parent artery, accompanied by balloon dilation. Nine months post-operatively, the patient's visual acuity had improved considerably.

Bilateral cavernous carotid aneurysms (CCAs) are often not amenable to neurosurgical clipping or endovascular coiling. Here, we report the case of a 50-year-old female who presented with a 1-year history of gradual severe headache. Preoperative angiograms revealed bilateral CCAs. Among these findings, the right giant CCA had been trapped after the external carotid artery-saphenous vein-middle cerebral artery (ECA-SV-MCA) bypass 8 years prior. Additionally, the left CCA was again trapped after the internal maxillary artery-radial artery-middle cerebral artery (IMA-RA-MCA) bypass, followed by parent artery occlusion (PAO), because of the enlargement of a 0...

Noninvasive computed tomography angiography (CTA) is widely used in acute ischemic stroke, even for diagnosing various internal carotid artery (ICA) occlusion sites, which often need cerebral digital subtraction angiography (DSA) confirmation. We evaluated whether clinical outcomes vary depending on the DSA-based occlusion sites and explored correlating features on baseline CTA that predict DSA-based occlusion site.We analyzed consecutive patients with acute ICA occlusion who underwent DSA and CTA. Occlusion site was classified into cervical, cavernous, petrous, and carotid terminus segments by DSA confirmation...
