Stroke endovascular thrombectomy related subarachnoid hyperdensity: incidence, predictive factors, and a proposed sub-classification.

Background: Subarachnoid hyperdensity (SAH) after endovascular thrombectomy is a well-known phenomenon. Nevertheless, the clinical significance and natural history of this phenomenon is not well described. In addition, we test previously postulated hypotheses of distal occlusions sites and antithrombotic use to SAH prevalence and extent.

Bleomycin sclerotherapy for venous vascular malformations of the tongue.

Background: Venous vascular malformations (VVMs) are congenital vascular anomalies, often impacting quality of life due to discomfort, swelling, and functional impairments. This study evaluates the efficacy of bleomycin sclerotherapy as a treatment for symptomatic VVMs of the tongue.

Methods: We conducted a retrospective review of all patients treated with this method in our institution between 2004 and 2024.

Dural Arteriovenous Fistulas: Baseline Cognitive Changes and Changes following Treatment: A Prospective Longitudinal Study.

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.

Clinical and Anatomical Characteristics of Perforator Aneurysms of the Posterior Cerebral Artery: A Single-Center Experience.

Introduction: Posterior cerebral artery (PCA) aneurysms represent up to 1% of all cerebral aneurysms. P1-P2 perforator aneurysms are thought to be even less prevalent and often require complex treatment strategies due to their anatomical and morphological characteristics, with risk of a perforator infarct. We studied the treatment of P1-P2 perforator aneurysms in a single-center cohort from a high-volume tertiary center, reporting clinical and anatomical characteristics, treatment strategies, and outcomes.
