Background And Purpose: Intracranial aneurysm, which underlies the vast majority of subarachnoid hemorrhage incidences, has a multifactorial etiology, and the importance of genetic factors is increasingly recognized. Development and rupture of intracranial aneurysms involve degradation and remodeling of the vascular wall matrix in which the matrix metalloproteinases (MMPs) play an important role. The possible impact of MMP gene polymorphisms on susceptibility to intracranial aneurysms is still controversial, with conflicting data from different reported studies.
Methods: In this study we analyzed 5 different functional promoter polymorphisms in the MMP-1, MMP-3, MMP-9, and MMP-12 genes in a sample of 92 patients with aneurysmal subarachnoid hemorrhage and 158 healthy control subjects, all from southern England.
Results: No significant difference was detected between the patient and control groups in genotype distribution of any of the polymorphisms studied.
Conclusions: The data do not support the hypothesis that MMP gene variations influence the development of intracranial aneurysms in the population studied.

Objective: To identify factors influencing neurological prognosis following traumatic brain injury (TBI) and to analyze the role of brain tissue oxygen pressure (PbtO) monitoring in prognostication.
Methods: In this case-control study, medical records of 412 individuals diagnosed with TBI were thoroughly examined and analyzed. The patients were divided into two groups based on their prognosis at three months post-injury: Good Prognosis (n = 321) and Poor Prognosis (n = 91).

Background: Aneurysmal subarachnoid haemorrhage continues to cause a significant burden of morbidity and mortality despite advances in care. Trials investigating local administration of thrombolytics have reported promising results.
Objectives: - To assess the effect of thrombolysis on improving functional outcome and case fatality following aneurysmal subarachnoid haemorrhage - To determine the effect of thrombolysis on the risk of cerebral artery vasospasm, delayed cerebral ischaemia, and hydrocephalus following subarachnoid haemorrhage - To determine the risk of complications of local thrombolysis in aneurysmal subarachnoid haemorrhage SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (last searched 9 March 2023), MEDLINE Ovid (1946 to 9 March 2023), and Embase Ovid (1974 to 9 March 2023).

This study aimed to provide an updated evidence of superior hypophyseal artery (SHA) aneurysms management, including their clinical implications, predictive factors for rupture, therapeutic approaches, and post-treatment outcomes. This systematic review and meta-analysis, following PRISMA guidelines, assessed the literature on superior hypophyseal artery aneurysms. Studies were selected based on predefined criteria, focusing on coiling and clipping interventions.

Background: The goal of the study is to use CT imaging in patients with aSAH to evaluate the anatomic distribution of hemorrhage and compartmentalization of subarachnoid space to investigate potential in vivo visualization of recently discovered layer named subarachnoid lymphatic-like membrane (SLYM).
Methods: We conducted a retrospective cohort study of cases with aneurysmal SAH (aSAH) at our institution between January 2015 and June 2022. Subarachnoid hemorrhage distribution into superficial and deep subarachnoid spaces was classified based on proximity to the dural or pial surfaces, respectively, as seen on multiplanar CT head.

Objectives: Aneurysmal subarachnoid haemorrhage (ASAH) is a severe stroke type, preventable by screening for intracranial aneurysms followed by treatment in high-risk individuals. We aimed to develop and validate a risk prediction model for ASAH in the general population to identify high-risk individuals.
Design: We used the population-based prospective cohort studies of the United Kingdom (UK) Biobank for model development and the Trøndelag Health (HUNT) Study for model validation.
