The Impact of Postprocedural Anticoagulant Use in Patients Undergoing Woven EndoBridge: A Multicenter Propensity Score-Matched Study.

The Woven EndoBridge (WEB) device has become a prominent treatment for wide-neck bifurcation intracranial aneurysms since its FDA approval in 2018. However, the impact of anticoagulant therapy on its efficacy and patient outcomes remains underexplored. This study aims to evaluate the effects of postoperative anticoagulant use on aneurysm occlusion, retreatment rates, and functional outcomes following WEB device implantation.

Middle meningeal artery embolization with standalone or adjunctive coiling for treatment of chronic subdural hematoma: Systematic review and meta-analysis.

Introduction: Middle meningeal artery embolization (MMAe) is increasingly utilized as a primary or secondary treatment for chronic subdural hematoma (cSDH) and is usually performed with liquid embolics or particles. Outcomes after MMAe with coiling as a standalone treatment, or an adjunct to other agents, have not been reviewed.

Methods: A systematic review of the literature was performed to identify all original research that included patients who underwent standalone or adjunctive coiling for MMAe.

Prediction of Symptomatic Intracranial Hemorrhage Before Mechanical Thrombectomy Using Machine Learning in Patients with Anterior Circulation Large Vessel Occlusion.

Background: Symptomatic intracranial hemorrhage (sICH) after mechanical thrombectomy (MT) is associated with worse outcomes. We sought to develop and internally validate a machine learning (ML) model to predict sICH prior to MT in patients with anterior circulation large vessel occlusion.

Methods: Consecutive adults who underwent MT for internal carotid artery/M1/M2 occlusions at a single institution were reviewed.

Management of internal carotid artery pathology with a covered stent: illustrative cases.

Background: Endovascular treatment of internal carotid artery (ICA) pathology includes reconstructive or deconstructive options. One reconstructive option is covered stent placement, although this is limited by a lack of devices designed specifically for neurointervention. The PK Papyrus is a balloon-mounted covered coronary stent that has a lower profile and is more flexible than other stent grafts, which makes it more suitable for treating ICA lesions.

Background: We evaluated how systolic blood pressure (SBP) and mean arterial pressure (MAP) parameters between presentation and reperfusion influence functional status and intracranial hemorrhage (ICH).

Methods: All patients who underwent MT for LVO at a single institution were reviewed. Independent variables included SBP and MAP measurements obtained on presentation, between presentation and reperfusion (pre-reperfusion), and between groin puncture and reperfusion (thrombectomy).

Comparison of Retroauricular and Reverse Question Mark Incisions for Decompressive Hemicraniectomy.

Background: The retroauricular (RA) incision has several theoretical benefits compared with the reverse question mark (RQM) incision for decompressive hemicraniectomy (DHC), but limited data comparing the 2 exist.

Methods: We conducted a serial cross-sectional study using primary AIS admissions in children ⩽ 17 years (weighted n = 2807) contained in the 2009-2019 KIDS Inpatient Database. Age-specific utilization frequency of IV-tPA and MT were calculated.

Embolization of a Dural Arteriovenous Fistula Using Transcranial Middle Meningeal Artery Access: 2-Dimensional Operative Video.

The transcranial approach for direct middle meningeal artery (MMA) access to embolize dural arteriovenous fistulas (dAVF) has been described, but limited information regarding the setup, equipment, and technique is available. We present the details of this hybrid approach in the setting of a ruptured Cognard grade IV tentorial dAVF (Video 1). The patient was an adult female who presented with nausea, vomiting, and dizziness and was found to have a cerebellar hemorrhage.
