Certain cavernous sinus (CS) dural arteriovenous fistulae (DAVFs) are difficult to access through transarterial or transvenous routes and may necessitate access through direct transorbital puncture of the superior ophthalmic vein (SOV) or the CS. However, in order to be successful, the accurate design of the puncture route and guidance are crucial. This study aimed to report our preliminary clinical experience using cone-beam CT with real-time fluoroscopic overlays for image guidance during transorbital needle puncture.

In case of cavernous sinus dural arteriovenous fistula, transvenous embolization of the cavernous sinus via the inferior petrosal sinus is generally sufficient. However, when inferior petrosal sinus a...
and Purpose: multiple carotid cavernous fistulas (CCFs) classifications have been proposed, but they lack of prediction for clinical presentation, natural history and hemorrhagic risk. Our aim is to e...
Transvenous approach via the inferior petrosal sinus (IPS) is the most commonly used route to access cavernous sinus dural arteriovenous fistulas (CSDAVF). The facial (FV) or superficial temporal vein...
Dural Arteriovenous Fistulas (DAVFs) in the anterior cranial fossa constitute approximately 1-1.5% of intracranial vascular malformations. Depending on the drainage patterns, the diagnosis of ethmoida...
Inferior petrosal sinus (IPS) is commonly adopted as a route in embolizing cavernous dural arteriovenous fistula (cDAVF). According to previous anatomical studies, more than 90% of people have IPS. Si...
The purpose of this study is assessment of safety, efficacy, and short-term outcome of SQUID™ in the embolization of Dural Arteriovenous Fistula
The primary objective of this study is to demonstrate the safety and efficacy of the PHIL® liquid in endovascular treatment of dural arteriovenous fistula.
This study is a prospective, multicenter, single-arm study. Patients with Dural Arteriovenous Fistulas (dAVF) have a few choice for safe treatment. In this study, all patients with qualify...
Spinal dural arteriovenous fistulas (SDAVFs) are the most common vascular disorder of the spine and account for approximately 70% of spinal vascular malformation.They are a rare pathology ...
Several studies showed that radiotherapy as brain tumors treatment may affect cognition. It was observed that durable memory impairments could arise at irradiated patients if radiotherapy ...
A method of hemostasis utilizing various agents such as Gelfoam, silastic, metal, glass, or plastic pellets, autologous clot, fat, and muscle as emboli. It has been used in the treatment of spinal cord and INTRACRANIAL ARTERIOVENOUS MALFORMATIONS, renal arteriovenous fistulas, gastrointestinal bleeding, epistaxis, hypersplenism, certain highly vascular tumors, traumatic rupture of blood vessels, and control of operative hemorrhage.
An acquired or spontaneous abnormality in which there is communication between CAVERNOUS SINUS, a venous structure, and the CAROTID ARTERIES. It is often associated with HEAD TRAUMA, specifically basilar skull fractures (SKULL FRACTURE, BASILAR). Clinical signs often include VISION DISORDERS and INTRACRANIAL HYPERTENSION.
Formation or presence of a blood clot (THROMBUS) in the CAVERNOUS SINUS of the brain. Infections of the paranasal sinuses and adjacent structures, CRANIOCEREBRAL TRAUMA, and THROMBOPHILIA are associated conditions. Clinical manifestations include dysfunction of cranial nerves III, IV, V, and VI, marked periorbital swelling, chemosis, fever, and visual loss.

Sampling of blood levels of the adrenocorticotropic hormone (ACTH) by withdrawal of blood from the inferior petrosal sinus. The inferior petrosal sinus arises from the cavernous sinus and runs to the internal jugular vein. Sampling of blood at this level is a valuable tool in the differential diagnosis of Cushing disease, Cushing syndrome, and other adrenocortical diseases.
An abnormal direct communication between an artery and a vein without passing through the CAPILLARIES. An A-V fistula usually leads to the formation of a dilated sac-like connection, arteriovenous aneurysm. The locations and size of the shunts determine the degree of effects on the cardiovascular functions such as BLOOD PRESSURE and HEART RATE.
