Dilated intercavernous sinuses: an MR sign of carotid-cavernous and carotid-dural fistulas.
نویسندگان
چکیده
Dilated venous channels traversing the sella and connecting the two cavernous sinuses were seen on contrast-enhanced MR images in four patients with angiographically proved carotid fistulas. The anatomy and variations of these so-called intercavernous sinuses are discussed and are demonstrated in Latex-injected anatomic specimens. Direct visualization of the intercavernous sinuses on contrast-enhanced MR images may serve as an ancillary sign for the diagnosis of carotid-cavernous or carotid-dural fistulas near the sella.

Dural Arteriovenous Fistulas in the Cavernous Sinus: Clinical Research and Treatment
Introduction. The purpose of this paper is to clarify the clinical course, with the dural carotid cavernous fistula (CCF), featuring a pallet of symptoms, paying special attention to radiological findings. Methods. Seventy-six consecutive patients with dural CCFs were investigated in detail, all of whom were defined by angiography. Results. The most common initial symptom was diplopia in 47 pat...
متن کاملIntercavernous sinus dural arteriovenous fistula treated with transvenous coil embolization: a case report.
The blood supply to the region of the cavernous sinus is provided by interconnecting branches of the internal and external carotid arteries, and it is from these vessels that dural arteriovenous fistulas (DAVFs) arise. It is very rare that DAVFs are located at the intercavernous sinuses region; in this case, a proper localization of the fistulous site is of extreme importance in order to succes...

A precise knowledge of the venous morphology of the carotid cavernous sinus is essential in order to choose the appropriate access routes to the cavernous sinus. The sinus is trabeculated and subdivided in compartments. Newton and Potts 1 mentioned two parts, the anterior and posterior part. The anterior receives blood from the superior ophthalmic vein (SOV), inferior ophthalmic vein (IOV), sph...
متن کاملSurgical transvenous embolization of a cortically draining carotid cavernous fistula via a vein of the sylvian fissure.
Percutaneous transvenous embolization is one of the most effective treatments of intracranial dural arteriovenous fistulas (AVFs) involving the dural sinuses. We present a unique case of surgical transvenous embolization in a 48-year-old man with a dural AVF of the cavernous sinus who presented with intracerebral hematoma. The dural AVF drained only into the vein of the sylvian fissure on angio...
متن کاملTreatment of dural carotid-cavernous fistulas via the superior ophthalmic vein.
Symptomatic patients with dural carotid-cavernous fistulas often require treatment. Traditional therapies, which often are not completely successful, include manual common carotid artery compression and embolization via transarterial routes. This report describes four symptomatic patients with spontaneous dural carotid-cavernous fistulas who were treated unsuccessfully with transarterial embolo...
