Higher Rate of Reinterventions After Transfemoral Carotid Artery Stenting in Symptomatic Patients: A Retrospective Stroke Center's Cohort Study between 2015-2024.

Introduction: Carotid artery stenosis is a significant contributor to ischemic strokes, and its surgical management includes carotid artery endarterectomy (CEA), transfemoral carotid artery stenting (TF-CAS), and trans carotid artery revascularization (TCAR). CEA has traditionally been preferred, but TF-CAS and TCAR are also excellent alternative options if the anatomy of the vessels allows them. This study reports our short- and mid-term outcomes after carotid artery revascularization in symptomatic patients at a stroke center.

The eSAH score: a simple practical predictive model for SAH mortality and outcomes.

We developed a simple quantifiable scoring system that predicts aneurysmal subarachnoid hemorrhage (aSAH) mortality, delayed cerebral ischemia (DCI), and modified Rankin scale (mRS) outcomes using readily available SAH admission data with SAH volume (SAHV) measured on computed tomography (CT). We retrospectively analyzed a cohort of 277 patients with aSAH admitted at our Comprehensive Stroke Center at Mayo Clinic in Jacksonville, Florida, between January 5, 2012, and February 24, 2022. We developed a mathematical radiographic model SAHV that measures basal cisternal SAH blood volume using a derivation of the ABC/2 ellipsoid formula (A = width/thickness, B = length, C = vertical extension) on noncontrast CT, which we previously demonstrated is comparable to pixel-based manual segmentation on noncontrast CT.

Intraplaque Hemorrhage and Plaque Ulceration Are More Likely in Patients with Symptomatic Mild-to-Moderate Carotid Artery Stenosis than in Symptomatic and Asymptomatic High-Grade Stenosis: A Retrospective Cohort Study.

Background: To compare a cohort of symptomatic patients with mild-to-moderate (<70%) carotid artery stenosis (CAS) with those patients with high-grade (≥70%) CAS (symptomatic and asymptomatic) to assess for markers that places them at a higher risk for stroke.

Methods: A propensity score-matched cohort study design for all patients who underwent carotid revascularization between 2015 and 2024 was utilized to compare the high-grade (≥70%) symptomatic and asymptomatic carotid stenosis groups against the mild to moderate (<70%) symptomatic carotid stenosis group. Matched variables included age, sex, and atrial fibrillation.

Anatomical analysis of vertebral arteries in vertebrobasilar dolichoectasia: A multi-center study.

Background: Vertebrobasilar dolichoectasia (VBD) is a rare disease with significant morbidity. Its propensity for posterior circulation and relationship with aneurysms is poorly understood. Here, we aimed to describe the anatomical characteristics of the vertebral arteries (VA) in patients with VBD.

Dramatic Reanimation and Spontaneous Re-Canalization of a Fourth Ventricular Hemorrhage: "REVIVE" Phenomenon.

Background: Intraventricular hemorrhage is a calamitous type of stroke where bleeding into the ventricular system can be defined as: primary, if confined within the ventricles; or secondary, due to intracerebral hemorrhage extending from adjacent parenchyma. Intraventricular blood clot can lead to secondary insult and inflammatory responses that culminates in hydrocephalus as the most common cause of death.

Purpose: THerein, we report a patient with a high modified Graeb scale and low Glasgow coma scale.
