Transnasal flow reduction in endovascular treatment for anterior cranial fossa dural arteriovenous fistula.

J Surg Case Rep 2020 Oct 20;2020(10):rjaa327. Epub 2020 Oct 20.

Department of Neurosurgery, Osaka University Graduate School of Medicine, Osaka, Japan.

Transarterial embolization (TAE) is a useful option for anterior cranial fossa-dural arteriovenous fistula (ACF-dAVF) as endovascular devices have progressed. Liquid agents are usually injected via a microcatheter positioned just proximal to the shunt pouch beyond the ophthalmic artery; however, high blood flow from the internal maxillary artery (IMA) often impedes penetration of embolic materials into the shunt pouch. Therefore, reducing blood flow from the IMA before embolization can increase the success rate. Read More

Efficacy and safety of embolization of dural arteriovenous fistulas via the ophthalmic artery.

Interv Neuroradiol 2021 Jun 26;27(3):444-450. Epub 2020 Oct 26.

Division of Neuroimaging and Neurointervention, Department of Radiology, Stanford University School of Medicine, Stanford, CA, USA.

Introduction: Dural arteriovenous fistulae (DAVF) are vascular lesions with arteriovenous shunting that may be treated with surgical obliteration or endovascular embolization. Some DAVF, such as anterior cranial fossa DAVF (AC-DAVF) derive their arterial supply from ophthalmic artery branches in nearly all cases, and trans-arterial embolization carries a risk of vision loss. We determined the efficacy and safety of trans-ophthalmic artery embolization of DAVF. Read More

A rare case of spinal dural arteriovenous fistula mimicking malignant glioma of the medulla oblongata: Significance of cerebral angiography for accurate diagnosis of brain stem region.

Surg Neurol Int 2020 12;11:287. Epub 2020 Sep 12.

Department of Neurosurgery, Ehime University School of Medicine, Toon, Ehime, Japan.

Background: The findings of a hyperintense sign on T2-weighted imaging (T2-WI) and gadolinium (Gd) contrast enhancement on magnetic resonance imaging (MRI) of the brain stem suggest malignant glioma. However, this pathological condition is probably uncommon, and it may be unknown that a dural arteriovenous fistula (DAVF) can imitate this radiological pattern. In addition, it is extremely rare to be caused by a spinal DAVF. Read More

Jugular Venous Reflux Can Mimic Posterior Fossa Dural Arteriovenous Fistulas on MRI-MRA.

AJR Am J Roentgenol 2021 06 2;216(6):1626-1633. Epub 2020 Sep 2.

Department of Radiology and Biomedical Imaging, Neurointerventional Section, University of California San Francisco, 505 Parnassus Ave, Rm L349, San Francisco, CA 94143.

Dural arteriovenous fistulas (DAVFs) are high-flow acquired shunts that can carry high risk of intracranial hemorrhage. Because DAVFs can often be managed by endovascular means, early and accurate diagnosis can markedly improve patient morbidity. Time-of-flight and arterial spin-labeling MRA have increased the diagnostic utility of MRI for DAVF by showing hemodynamic rather than anatomic evidence of shunting. Read More

Initial experience with the Scepter Mini dual-lumen balloon for transophthalmic artery embolization of anterior cranial fossa dural arteriovenous fistulae.

J Neurointerv Surg 2020 Nov 20;12(11):1132-1136. Epub 2020 May 20.

Radiology, Neuroadiology and Neurointervention Division, Stanford University School of Medicine, Stanford, California, USA

Background: Precise delivery of liquid embolic agents (LEAs) remains a challenge in the endovascular treatment of dural arteriovenous fistulae (dAVFs) and cerebral arteriovenous malformations (cAVMs). Despite significant advances in the past decade, LEA reflux and catheter navigability remain shortcomings of current endovascular technology, particularly in small and tortuous arteries.

Department of Neurosurgery, Faculty of Medicine, University of Tsukuba, Tsukuba City, Ibaraki, Japan.

Anterior cranial fossa (ACF) dural arteriovenous fistulas (DAVFs) are mainly fed by the ethmoidal arteries and sometimes have pial arterial feeders. DAVFs with pial arterial supply in ACF are extremely rare because most of the reported cases of DAVFs with pial arterial supply are located at the transverse sigmoid sinus and tentorium. A 68-year-old male presented with dizziness. Read More

Surgical Obliteration of Anterior Cranial Fossa Dural Arteriovenous Fistulas via Unilateral High Frontal Craniotomy.

World Neurosurg 2019 Oct 5;130:89-94. Epub 2019 Jul 5.

Department of Neurosurgery, Seoul National University Hospital, Seoul, Korea.

Background: Surgical obliteration is generally recommended for anterior cranial fossa dural arteriovenous fistulas (ACF DAVFs) because of a high risk of bleeding and the difficulty of endovascular approaches. Surgical obliteration is generally performed via a frontobasal craniotomy; however, it is slightly excessive over the target fistula. Here, we present 2 cases of ACF DAVFs treated with small craniotomy without frontal sinus involvement and a review of the related literature. Read More
