Competing pathways of intracranial aneurysm growth: linking regional growth distribution and hemodynamics.
J Neurosurg
January 2025
1Department of Bioengineering, George Mason University, Fairfax, Virginia.
Objective: The complex mix of factors, including hemodynamic forces and wall remodeling mechanisms, that drive intracranial aneurysm growth is unclear. This study focuses on the specific regions within aneurysm walls where growth occurs and their relationship to the prevalent hemodynamic conditions to reveal critical mechanisms leading to enlargement.
Methods: The authors examined hemodynamic models of 67 longitudinally followed aneurysms, identifying 88 growth regions.
Exploring Mixed Reality for Patient Education in Cerebral Angiograms: A Pilot Study.
Appl Clin Inform
January 2025
Neurosurgery, Texas Health Harris Methodist Hospital Fort Worth, Fort Worth, United States.
Background: Cerebral aneurysms (CAs) affect 3-5% of the general population, with saccular aneurysms being the most common type. Despite advances in treatment, patient understanding of CAs and associated procedures remains limited, impacting informed consent and treatment outcomes.
Objectives: This pilot study aims to evaluate the effectiveness of mixed reality (MR) technology in enhancing patient education and understanding of cerebral angiograms and aneurysm treatment, thereby improving the patient-surgeon communication process.
Risk factors of short-term poor functional outcomes and long-term durability of ruptured large or giant intracranial aneurysms.
J Neurosurg
January 2025
13Department of Neurosurgery, Shimane Prefectural Central Hospital, Shimane, Japan.
Objective: Aneurysmal subarachnoid hemorrhage (SAH) is associated with high morbidity and mortality rates. In particular, functional outcomes of SAH caused by large or giant (≥ 10 mm) ruptured intracranial aneurysms are worsened by high procedure-related complication rates. However, studies describing the risk factors for poor functional outcomes specific to ruptured large/giant aneurysms are sparse.

Department of Neurosurgery, Nakamura Memorial Hospital, South 1, West 14, Chuo-ku, Sapporo, Hokkaido, 060-8570, Japan.
Spontaneous thrombosis of intracranial aneurysms is rare. Spontaneous regression of unruptured small saccular aneurysms is even more rare. A 76-year-old woman with a history of hypertension and dyslipidemia was referred for evaluation of an unruptured intracranial aneurysm.

December 2024
Changhai Hospital, Navy Medical University, Shanghai, People's Republic of China.
To describe the mid-term safety and efficacy of Leo baby stent applied in saccular wide-neck intracranial aneurysms (IAs). 151 patients harboring 156 IAs treated with Leo baby stent from March 2021 to October 2023 were enrolled for further analysis. Among 156 IAs, 142 cases (91.
