Comparison of silent MRA and time-of-flight MRA in the depiction and grading of brain arteriovenous malformations.

Background: Preliminary small-sample studies suggest that silent magnetic resonance angiography (MRA) has an advantage over time-of-flight MRA (TOF MRA) in the characterization of brain arteriovenous malformation (BAVM), but did not examine whether the imaging performance of silent MRA was affected by the intrinsic features of BAVM or common clinical factors. This study sought to compare silent MRA and TOF MRA in terms of the visualization and grading of BAVMs in various clinical settings.

Methods: In total, 85 participants (50 males, 35 females; mean age: 33.

A Dural Arteriovenous Fistula in the Falx Cerebri Solely Supplied by the Distal Dural Supply of the Anterior Cerebral Artery.

Dural arteriovenous fistulas of the falx cerebri are extremely rare and may be associated with the falcine sinus. The distal dural supply from the anterior cerebral artery comes via the pericallosal artery. This artery can send branches to the free edge of the falx cerebri.

Inhibition of Angiopoietin-2 rescues sporadic brain arteriovenous malformations by reducing pericyte loss.

Brain arteriovenous malformations (bAVMs) are a major cause of hemorrhagic stroke in children and young adults. These lesions are thought to result from somatic KRAS/BRAF mutations in brain endothelial cells (bECs). In this study, we introduce a new bAVM model by inducing a brain endothelial-specific Braf mutation using the Slc1o1c1(BAC)-CreER driver line.

Discriminators of Paraclinoid Aneurysm Rupture Based On Morphological Computer-Assisted Semiautomated Measurement (CASAM) and Hemodynamic Analysis.

Background: Paraclinoid aneurysms, arising from the proximal dural ring and extending to the origin of the posterior communicating artery of the internal carotid artery (ICA), represent a significant proportion of all intracranial aneurysms (IAs). Accurate prediction of the rupture risk of paraclinoid aneurysms is crucial for optimal management. The objective of this study was to identify risk factors for the rupture of paraclinoid aneurysms on the basis of computer-assisted semiautomated measurement (CASAM) and hemodynamics.

Intracranial dural arteriovenous fistulas with pial arterial supply: A narrative review.

Intracranial dural arteriovenous fistula (DAVF) is a relatively complex intracranial condition, and its clinical presentation and treatment strategies often vary significantly due to various factors. Although the cure rate of intracranial DAVF is currently high, there is still a lack of understanding of its etiology and pathogenesis. There is ongoing controversy regarding the treatment strategies for DAVF associated with the pial arteries, and there is a lack of understanding of its pathogenesis.

Trans-arterial embolization of anterior cranial fossa dural arteriovenous fistulas via the sphenopalatine artery: a technique report.

Background: Trans-arterial embolization (TAE) via the ophthalmic artery and middle meningeal arterial are the common arterial routes for anterior cranial fossa (ACF) dural arteriovenous fistulas (DAVFs). However, TAE via the sphenopalatine artery (SPA) to treat ACF DAVFs is rarely reported. Here, we describe 14 cases of ACF DAVFs that were either treated solely or in conjunction with other arterial routes via the SPA.

Parasagittal dural arteriovenous fistulas.

Background: The majority of studies on parasagittal dural arteriovenous fistulas (DAVFs) have been limited to case reports or case series, and they are frequently reported alongside true superior sagittal sinus (SSS) DAVFs. Because of the selective bias present in the reporting of dispersed small numbers of parasagittal DAVFs, the results of each study may influence the findings. As a result, we present a large sequential cohort of parasagittal DAVFs from our institution spanning a 20-year period.
