Detailed information about the anatomy of traumatic carotid cavernous fistula (CCF) is required for determining the appropriate treatment strategy. We report the usefulness of C-arm cone-beam computed tomography (CBCT) for visualizing traumatic CCF during endovascular treatment. A 63-year-old woman presented with right pulsating tinnitus 1 week after a bicycle accident. ...

We report a rare case of thrombosis of the superior sagittal sinus associated with a parafalcine meningioma resulting in a superior sagittal sinus dural arteriovenous fistula (dAVF). We conclude that dural sinus thrombosis is a significant predisposing factor for development of a dAVF. A 60-year-old man had a left parietal ...

Most patients with direct carotid-cavernous fistulas (CCFs) present with dramatic symptoms including proptosis, chemosis, and diplopia. We report a patient with a direct/high-flow CCF whose only initial symptom was pulse-synchronous tinnitus. Following diagnostic angiography, she developed mild symptoms and dramatic angiographic changes over a period of 3 days. Complete occlusion ...

BACKGROUND: Juvenile Paget disease (JPD) is a rare genetic bone disorder, also affecting the immune and vascular systems. We describe the first ever case of JPD associated with bilateral giant cavernous carotid artery aneurysms in a child. CASE DESCRIPTION: A child with known JPD presented with left abducens nerve palsy ...

Arterial bleeding during transsphenoidal surgery for pituitary adenoma is known complication. This usually happens due to rupture of intracavernous carotid or delayed hemorrhage due to the carotico-cavernous fistula and/or pseudoaneurysm. There is also evidence that cavernous carotid aneurysms may occur with pituitary tumors, yet largest series failed to demonstrate any ...

During sinus-lift surgery, certain intra-osseous vessels may be accidentally cut and this cause bleeding complications in approximately 20% of osteotomies. Therefore, understanding vascular details of the maxilla is very important for the surgeon. Here, we have given an anatomical overview of maxillary sinus vascularization through anatomical dissection. We have analyzed ...

Superficial temporal vein catheterization was used to embolize a dural arteriovenous malformation of the cavernous sinus in a 44-year-old woman. The pertinent venous anatomy is discussed. This route may provide crucial access to the cavernous sinus when conventional approaches such as the Inferior petrosal sinus catheterization are difficult.

The relatively common persistent left superior caval vein (LSCV) is in most cases associated with doubling of the superior caval vein. A persistent LSCV with absent right superior caval vein (RSCV)-a rather rare event-was found during our course of gross anatomy. The LSCV drained into an enlarged coronary sinus, which ...

Carotid-cavernous sinus fistulas (CCF) are abnormal communications between the carotid artery and the cavernous sinus. Most spontaneous CCFs are low-flow fistulas, supplied by branches of the omolateral internal carotid artery or the external carotid artery. A 64-year-old man, with increasing diplopia, mild exophthalmos on the left side, blurred left vision ...
Johnson Paul B - - 2010
A 4-month-old boy presented with the sudden onset of proptosis and dilated episcleral veins. CT revealed an enlarged superior ophthalmic vein and diffusely thickened extraocular muscles. MRI and angiography confirmed a dural middle meningeal--cavernous sinus fistula. Embolization was performed leading to successful resolution of the patient's signs and symptoms. Spontaneous ...

We describe a rare case of traumatic persistent trigeminal artery (PTA) - cavernous sinus fistula. Cerebral angiography showed direct communication between the right PTA and the cavernous sinus which was treated by transcathether arterial embolization. Although previous reports have indicated the use of more coils to treat this condition, we ...

OBJECT: So-called direct carotid-cavernous fistulas (CCFs) are commonly treated by detachable balloons or coils to occlude the shunt while sparing the carotid artery. Liquid embolic agents have been rarely used, and in particular, to the authors' knowledge, the use of Onyx as the sole agent has never been reported in ...

The treatment of indirect carotid cavernous fistulas (CCFs) is challenging and primarily accomplished by endovascular means utilizing a variety of embolic agents. Transvenous access to the cavernous sinus is the preferred method of embolizaiton of indirect CCFs as they are frequently associated with numerous small-caliber meningeal branches. Although the inferior ...

Carotid sinus hypersensitivity (CSH) is a common cause of fainting and falls in the older adult population and is diagnosed by carotid sinus massage (CSM). Previous work has suggested that age-related stiffening of blood vessels reduces afferent input from the carotid sinus leading to central upregulation of the overall arterial ...

Chemosis of the eyes is usually attributed to carotid cavernous sinus dural arteriovenous fistulae. Herein, we reviewed unusual cases in which chemosis of the eyes originated from dural ateriovenous fistulae (dAVFs) that were distinctly different from carotid cavernous sinus fistulae. Cases in which ocular symptoms were related to increased intracranial ...

Takayasu aortoarteritis (TA) rarely affects the nervous system, but when it does, it usually manifests as cerebral ischemia or stroke. These strokes have mainly been attributed to stenotic extracranial vessels. Stenoses of intracranial vessels, although rare in TA, can occur due to either embolization into the vessel or because of ...

Carotid-cavernous fistulae are abnormal arterial communications within the cavernous sinus. Endovascular obliteration is the mainstay therapy for the definitive treatment of these lesions. Several approaches have been described. These include transarterial or transvenous embolization with balloons, coils, particles, or covered stents, and arterial sacrifice. The preferred technique is based on ...

Direct carotid cavernous fistulas (CCF) are generally well managed by simple endovascular treatment. We report an 8-year-old boy who required subsequent direct puncture of the cavernous sinus to completely obliterate the residual fistula after both transarterial and transvenous embolization had been performed. He presented with a mild right frontal headache, ...

Carotid-cavernous fistulas are abnormal arteriovenous communications either directly between the internal carotid artery and the cavernous sinus or between the dural branches of the internal and external carotid arteries. These fistulas predominantly present with ocular manifestations and they are treated mainly by endovascular techniques in most cases. A detailed review ...

To show that migraine pain is not related to dilatation of the dural meningeal arteries. The origin of the pain in migraine has not yet been adequately explained and remains the subject of vigorous debate. Current theories implicate changes in the trigeminovascular system, which is defined as comprising the large ...

Carotid cavernous fistulas (CCFs) are abnormal communications between the carotid arterial system and the cavernous sinus. CCFs are broadly classified as either direct or indirect. Surgical treatment of CCFs is technically difficult and is associated with significant morbidity. Endovascular techniques from either an arterial or a venous approach have become ...
