Transarterial embolization of anterior cranial fossa dural arteriovenous fistulas as a first-line approach: A retrospective single-center study.

Background: Anterior cranial fossa (ACF) dural arteriovenous fistulas (DAVFs) present unique treatment challenges due to their complex angioarchitecture and high risk of hemorrhage. Recent advancements in endovascular techniques have highlighted the potential of transarterial embolization in managing these fistulas.

Objective: The purpose of this study is to evaluate the clinical and angiographic outcomes of transarterial embolization (TAE) as a first-line treatment for ACF DAVFs over a twenty-year period.

Here we report the clinical and angiographic outcomes in patients with tentorial dural arteriovenous fistulas who underwent endovascular treatment as first-line treatment.

Materials And Methods: A retrospective analysis was conducted on 83 patients with tentorial dural arteriovenous fistulas treated at our center from April 2009 to November 2023 using endovascular treatment.

Our objective was to investigate the independent predictors of recurrence and unfavorable functional outcome of low-and intermediate-grade LS-DAVFs after EVT.

Materials And Methods: Retrospectively reviewed our database of prospectively collected information for all patients with low and intermediate-grade LS-DAVFs that underwent EVT from May 2004 to December 2021.

Middle Meningeal Artery Embolization for Nonacute Subdural Hematoma.

Background: The effect of embolization of the middle meningeal artery in patients with subacute or chronic subdural hematoma is uncertain.

Methods: We performed a multicenter, open-label, randomized trial in China, involving patients with symptomatic nonacute subdural hematoma with mass effect. Patients were assigned to undergo burr-hole drainage or receive nonsurgical treatment at the surgeon's discretion, and patients in each group were then randomly assigned, in a 1:1 ratio, to undergo middle meningeal artery embolization with liquid embolic material or to receive usual care.

Advances in the Study of KRAS in Brain Arteriovenous Malformation.

Background: Brain arteriovenous malformation (bAVM) is an abnormal vascular mass with disordered arteriovenous connection. Endothelial KRAS mutation is common in bAVM. In vivo studies have demonstrated that mutations of KRAS in somatic cells can induce bAVM-like angiogenesis, suggesting that KRAS gene may play a key role in the development and progression of bAVM.

Comparison of staged-stent and stent-assisted coiling technique for ruptured saccular wide-necked intracranial aneurysms: Safety and efficacy based on a propensity score-matched cohort study.

Background: Application of stent-assisted coiling and FD in acute phase of ruptured wide-necked aneurysms is relatively contraindicated due to the potential risk of ischemic and hemorrhagic complications. Scheduled stenting after initial coiling has emerged as an alternative paradigm for ruptured wide-necked aneurysms. The objective of this study is to evaluate the safety and efficacy of a strategy of staged stent-assisted coiling in acutely ruptured saccular wide-necked intracranial aneurysms compared with conventional early stent-assisted coiling strategy propensity score matching in a high-volume center.

Objective: This study aims to compare the safety and efficacy of stent-assisted coiling (SAC) with those of coiling alone (CA) for the treatment of ruptured tiny intracranial aneurysms.

Methods: We enrolled 245 patients with ruptured tiny intracranial aneurysms treated with coil embolization. Patients were grouped into SAC and CA groups.

CT Hyperdense Artery Sign and the Effect of Alteplase in Endovascular Thrombectomy after Acute Stroke.

Background Recent evidence suggests that presence of an intracranial arterial thrombus with a hyperdense artery sign (HAS) at noncontrast CT (NCCT) is associated with better response to intravenous alteplase. Patients with HAS may benefit more from combined intravenous alteplase and endovascular treatment (EVT). Purpose To investigate whether HAS at NCCT modifies the treatment effect of adding intravenous alteplase on clinical outcome in patients with acute large-vessel occlusion undergoing EVT.

Objective: We investigated the safety and efficacy of the Numen coil compared with the Axium coil in the treatment of intracranial aneurysms.

Methods: Because CATCH (Coil Application Trial in China) is a prospective randomized controlled open-label noninferiority trial conducted in 10 centers across China, patients who fulfilled the inclusion and exclusion criteria were randomized 1:1 to either a test group (Numen) or a control group (Axium). The primary outcome was based on successful aneurysm occlusion at 6 months follow-up, whereas secondary outcomes included technical success, the recanalization and retreatment rates, and the rate of serious adverse events (SAEs) at 6 months and 12 months follow-up.

Treatment delay from aneurysmal subarachnoid hemorrhage to endovascular treatment: a high-volume hospital experience.

Background: Early treatment for patients with aneurysmal subarachnoid hemorrhage (aSAH) could significantly reduce the risk of re-bleeding and improve clinical outcomes. We assessed the different time intervals from the initial hemorrhage, admission, and endovascular treatment and identified the risk factors contributing to delay.

Methods: Between February 2017 and December 2019, 422 consecutive aSAH patients treated in a high-volume hospital were collected and reviewed.

Endovascular treatment of vertebro-vertebral arteriovenous fistula in neurofibromatosis type I: A report of two cases and literature review with a focus on endovascular treatment.

Vertebro-Vertebral arteriovenous fistula (VV-AVF) associated with neurofibromatosis Type I (NF-1) is rare.
