BACKGROUND AND PURPOSE: Sinus stenosis occasionally occurs in dural arteriovenous fistulas. Sinus stenosis impedes venous outflow and aggravates intracranial hypertension by reversing cortical venous drainage. This study aimed to analyze the likelihood of sinus stenosis and its impact on cerebral hemodynamics of various types of dural arteriovenous fistulas. MATERIALS AND METHODS: Forty-three cases of dural arteriovenous fistula in the transverse-sigmoid sinus were reviewed and divided into 3 groups: Cognard type I, type IIa, and types with cortical venous drainage...

Sigmoid sinus diverticulum (SSD) is a rare vascular disorder due to dehiscence of the sigmoid plate. It may be associated with prediverticular venous sinus stenosis (SS) and usually presents as pulsatile tinnitus. The mechanism of development of the SSD and tinnitus from a sinus diverticulum and associated SS is unclear. Previous case reports have suggested that remodeling of the venous system targeting the stenosis, elimination of the diverticulum, or both, have resulted in symptom relief. We present a case of SSD with SS, treated by stenting of the stenosis along with coil embolization of the diverticulum, resulting in complete relief of symptoms...

A 47-year-old woman developed a headache and tinnitus in her right ear followed by sudden-onset left hemiparesis. She had no history of trauma or thrombophilia. Arteriography showed an occlusion of the superior sagittal sinus, and a stenosis of the right transverse sinus. She was treated with anticoagulants; thereafter her deficits and sinus thrombosis immediately improved. However, 7 months after the onset, she noticed tinnitus in her left ear. Arteriography showed a dural arteriovenous fistula extending from the left occipital artery to the left transverse and sigmoid sinus, but no recurrence of the cerebral venous sinus thrombosis...

Idiopathic intracranial hypertension (IIH) occurs rarely, with severe patients recalcitrant to pharmacologic management often requiring cerebrospinal fluid diversion. We report two patients with variant IIH successfully treated with venous sinus stenting: 1) A 65-year-old man with severe vision loss, papilledema, and cognitive decline treated with four telescoped stents across a long, severely stenotic transverse-sigmoid system, and 2) a 58-year-old woman with headaches, vision loss, and papilledema secondary to a jugular paraganglioma causing severe jugular bulb stenosis that required contralateral venous sinus stenting...

Endovascular embolization is the treatment of choice for carotid-cavernous fistulas (CCFs), but failure to catheterize the cavernous sinus may occur as a result of vessel tortuosity, hypoplasia, or stenosis. In addition to conventional transvenous or transarterial routes, alternative approaches should be considered. The authors present a case in which a straightforward route to the CCF was accessed via transsphenoidal puncture of the cavernous sinus in a neurosurgical hybrid operating suite. This 82-year-old man presented with severe chemosis and proptosis of the right eye...

: Intracranial pressure (ICP) is the pressure inside the bony calvarium and can be affected by a variety of processes, such as intracranial masses and edema, obstruction or leakage of cerebrospinal fluid, and obstruction of venous outflow. This review focuses on the imaging of 2 important but less well understood ICP disorders: idiopathic intracranial hypertension and spontaneous intracranial hypotension. Both of these ICP disorders have salient imaging findings that are important to recognize to help prevent their misdiagnosis from other common neurological disorders...

Dural arteriovenous fistula (DAVF) of the transverse sinus with ophthalmic manifestations in young children are rare. We reviewed two cases of direct AVF of the transverse sinus with ocular manifestations managed at our institution. The first, a 2.5 years old male child presented with left exophthalmos. Angiography revealed AVF between the occipital artery and the transverse sinus. The second, a 2 years old female child, complained of left exophthalmos. Imaging studies showed bilateral direct AVFs of the transverse sinus with bilateral dysmaturation of the sigmoid sinus...

BACKGROUND AND PURPOSE: Idiopathic intracranial hypertension has been associated with dural venous sinus stenosis in some patients, but the hemodynamic environment of the dural venous sinuses has not been quantitatively described. Here, we present the first such computational fluid dynamics model by using patient-specific blood pressure measurements. MATERIALS AND METHODS: Six patients with idiopathic intracranial hypertension and at least 1 stenosis or atresia at the transverse/sigmoid sinus junction underwent MR venography followed by cerebral venography and manometry throughout the dural venous sinuses...

Venous anomalies are the most commonly identified abnormality by imaging in the work-up for pulse synchronous tinnitus. Potential diagnoses include idiopathic intracranial hypertension, sigmoid sinus wall anomalies, transverse and sigmoid sinus stenosis, jugular bulb anomalies, and prominent posterior fossa emissary veins. These causes are discussed in detail along with the association between sigmoid sinus wall anomalies and idiopathic intracranial hypertension.

Venous anomalies are diagnostic and therapeutic challenges. Subclavian or superior vena cava stenosis can be developed and venous return can be achieved via cardiac veins and coronary sinus in patients with central venous catheter for long-term hemodialysis. These types of abnormalities are not extremely rare especially in patients with a history of central venous catheter placement. Detection of these anomalies and subclavian vein stenosis before the surgical creation of hemodialysis fistulae or tunneled central venous catheter placement may prevent unnecessary interventions in those patients...

A persistent left superior vena cava (PLSVC) is a rare, under-recognized congenital anomaly. The PLSVC is incidentally discovered during central venous access procedures when access is obtained from the left internal jugular vein. The vast majority of PLSVCs drain into the right atrium; however, it is critical to recognize a PLSVC that drains into the left atrium as it can predispose to systemic dispersion of emboli through bypassing the lungs. Additionally, PLSVC catheterization has also been previously reported to be associated with cardiac dysrhythmias, venous stenosis, coronary sinus thrombosis, cardiac tamponade, and cardiac arrest...
