Background: Optic nerve sheath diameter (ONSD) is a promising noninvasive parameter for intracranial pressure (ICP) assessment. However, in the setting of aneurysmal subarachnoid hemorrhage (aSAH), several previous studies have reported no association between ultrasonically measured ONSD and ICP. In this study, we evaluate ONSD in patients with aSAH using a novel method of automated real-time ultrasonographic measurements and explore whether factors such as having undergone surgery affects its association to ICP.

[Clinical analysis of Tolosa-Hunt syndrome].

Zhonghua Yan Ke Za Zhi

January 2025

Department of Ophthalmology, Tianjin Medical University General Hospital, Tianjin300052, China.

Article Synopsis
  • The study analyzed clinical features of Tolosa-Hunt syndrome (THS), a type of painful ophthalmoplegia, by collecting data from patients diagnosed at a hospital over four years.
  • A total of 35 patients were included, with 18 diagnosed with THS, who typically presented symptoms like pain, ptosis, and MRI abnormalities, alongside various immunological findings.
  • Treated with glucocorticoids, most THS patients saw symptom relief within weeks, though some experienced relapses during follow-up.

Background: Granulomatosis with polyangiitis (GPA) is an autoimmune multisystem disorder characterized by small vessel vasculitis with granulomatous inflammation. In this report, we describe a unique case of GPA who presented with complete heart block (CHB) and developed complications due to intracranial large vessel involvement.

Case Summary: A 47-year-old gentleman presented with CHB with a background history of arthralgia and blood-tinged nasal discharge.

Analysis of the efficacy and factors affecting the prognosis of intracranial dissecting aneurysm treated with multi-stent overlap technique.

BMC Neurol

December 2024

Department of Neurological Surgery, The First College of Clinical Medical Science, China Three Gorges University, Yichang Central People's Hospital, 183 Yiling Avenue, Yichang City, Wujiagang District, China.

Objective: The study aims to identify characteristics that impact the postoperative prognosis and recurrence of intracranial dissecting aneurysms (IDA) patients treated using multi-stent overlapping techniques.

Methods: Clinical data from 69 IDA patients treated with multistate-assisted spring coil embolization at the hospital between January 2017 and October 2023 were retrospectively reviewed, including clinical and imaging data gathered at admission and discharge. The prognosis was determined based on mRS grade at discharge, and the patients were divided into excellent prognosis (mRS 0-2 points) and poor prognosis (mRS 3-6 points).

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.
