Ethmoidal dural arteriovenous fistulas (DAVFs) have a near-universal association with cortical venous drainage and a malignant clinical course. Endovascular treatment options are often limited due to the high frequency of ophthalmic artery ethmoidal supply. A 64-year-old gentleman presented with syncope and was found to have a right ethmoidal DAVF. Rather than the traditional bicoronal craniotomy, an endoscope-assisted mini-pterional approach for clip ligation is demonstrated. The mini-pterional craniotomy allows a minimally invasive approach to ethmoidal DAVF via a lateral trajectory. The endoscope can help achieve full visualization in the narrow corridor.The video can be found here: https://youtu.be/ZroXp-T35DI.

Venous interruption through surgical clip ligation is the gold standard treatment for ethmoidal dural arteriovenous fistula (e-dAVF). Their malignant natural history is attributable to the higher pred...
This video demonstrates the diagnosis and surgical ligation of a C1 dural arteriovenous fistula via a far lateral, transcondylar approach. The patient's dural arteriovenous fistula was identified by M...
A 67-year-old male presented to the hospital with a left anterior cranial fossa arteriovenous fistula connecting the anterior ethmoidal artery to the cavernous sinus and superior sagittal sinus. After...
Intracranial dural arteriovenous fistulas (DAVFs) are an uncommon pathology, and a sphenoparietal drainage pattern is certainly rare. We present a case of a de novo sphenoparietal dural arteriovenous ...
Indocyanine-green videoangiography (ICG-V) is used with increasing frequency in neurovascular surgery. ICG-V use in spinal dural arteriovenous fistulas (DAVFs) allows visualization of the hemodynamics...
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...
This study aims to compare the results of two mini invasive surgical approaches in abdominal aortic surgery: mini lumbotomy with retroperitoneal approach versus mini laparotomy with transp...
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 ...
A secondary headache disorder attributed to low CEREBROSPINAL FLUID pressure caused by SPINAL PUNCTURE, usually after dural or lumbar puncture.
A vessel that directly interconnects an artery and a vein, and that acts as a shunt to bypass the capillary bed. Not to be confused with surgical anastomosis, nor with arteriovenous fistula.
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.
Abnormal formation of blood vessels that shunt arterial blood directly into veins without passing through the CAPILLARIES. They usually are crooked, dilated, and with thick vessel walls. A common type is the congenital arteriovenous fistula. The lack of blood flow and oxygen in the capillaries can lead to tissue damage in the affected areas.
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.
