Background/aim: Brain arteriovenous malformations (AVMs) are vascular malformations characterized by dysmorphic, aberrant vasculature. During previous surgeries of compact nidus brain AVMs (representing the majority of cases), we have observed a "shiny" plane between nidal and perinidal AVM vessels and the surrounding grey and white matter and hypothesized that preoperative neuroimaging of brain AVMs may show a neuroradiological correlate of these intraoperative observations.
Patients And Methods: We retrospectively reviewed and analyzed multiplanar and multisequence 3-Tesla magnetic resonance (3T MR) imaging in five consecutive brain AVMs with special attention on imaging characteristics of the brain-AVM interface, i.
Article Synopsis
- MMAE (middle meningeal artery embolization) is being investigated as an effective treatment for chronic subdural hematoma (cSDH), focusing on its efficiency based on the cause and structure of cSDH.
- A study with 52 patients treated with MMAE analyzed pre- and post-treatment cSDH thickness and volume using CT imaging, comparing both spontaneous and traumatic cases.
- Results showed a significant reduction in cSDH thickness and volume for both groups, with spontaneous cases showing more improvement at 6-12 months, suggesting long-term follow-up may be crucial for traumatic cases.
Background And Purpose: Dural arteriovenous fistulas (DAVFs) exhibit varied clinical manifestations, and high-grade cases are associated with both a risk of hemorrhage and (in certain cases) dementia. Less known, however, is the association between DAVF and more subtle cognitive changes, which might not be clinically apparent without formal neurocognitive testing. This study prospectively assesses baseline cognitive changes in patients with unruptured DAVFs and looks at the effects of treatment on any such changes.

- - The text discusses the need for high-flow bypasses in treating complex aneurysms from the ICA or MCA, highlighting the limitations of traditional graft options like the saphenous vein and radial artery.
- - It introduces the lateral circumflex femoral artery as a viable and easily harvested alternative graft vessel for these bypass procedures.
- - The conclusion emphasizes that the lateral circumflex femoral artery is not only easy to obtain but also a reliable choice for high-flow bypasses in complex aneurysm cases.
Background/objectives: Headaches in Moyamoya angiopathy are common but poorly understood. We aimed to investigate if headaches in Moyamoya angiopathy improve after revascularization surgery and whether this is associated with improvement in cerebrovascular reactivity on MRI (CVR-MRI).
Methods: We included consecutive adult patients with Moyamoya angiopathy who had chart data on headaches, CVR-MRI, and underwent extracranial-intracranial bypass surgery between January 2010 and September 2022 at a tertiary neurovascular referral center.
