Background: To present the combined treatment of fusiform basilar artery aneurysms consisting of a surgical posterior fossa decompressive craniectomy and ventriculoperitoneal (VP) shunt operation at the same sitting, before the endovascular procedure with telescopic stenting of the aneurysmatic vessel segment in four cases.
Methods: Combined treatment involving surgical procedure consisting of ventriculoperitoneal shunt placement for hydrocephalus and an occipital bone craniectomy and C1 vertebrae posterior laminectomy to decompress the posterior fossa in the same session. After surgery, the patients were loaded with acetylsalicylic acid and clopidogrel, and then the endovascular treatment was performed.
Results: All of the procedures were performed successfully without technical difficulty. The patients tolerated the procedures well and all cases showed remodelling with the overlapping stent technique. The patients were discharged home with baseline neurological situation and computed tomography (CT) angiography was performed at the 3rd month.
Conclusion: This technique is a safer endovascular approach to treating symptomatic fusiform basilar artery aneurysms by protecting patients from both the haemorrhagic complications of anticoagulant therapy and thrombotic complications due to the interruption of anticoagulant therapy, while treating the hydrocephalus and compression by surgical means.

Comparison between ruptured anterior choroidal artery aneurysms and ruptured intracranial aneurysms in other locations in relation to aneurysm dimensions at rupture.
Acta Neurochir (Wien)

Division of Neuroradiology and Joint Department of Medical Imaging, University Health Network and Toronto Western Hospital, Toronto, ON, M5T 2S8, Canada.
Purpose: It was noticed that anterior choroidal artery (AChoA) aneurysms appear to rupture at relatively smaller sizes compared with aneurysms in other intracranial locations, based on anecdotal clinical experience. We therefore aimed to compare ruptured AChoA aneurysms with other ruptured aneurysms in other intracranial locations, pertaining to aneurysm dimensions. This may help in finding out if the rupture risk stratification, based on the amalgamation of aneurysms of multiple locations in one group, precisely estimates aneurysm rupture risk.

Intracranial atherosclerosis (ICAS) is a major cause of ischemic stroke, disproportionately affecting populations with significant vascular risk factors. Although ICAS imposes a considerable health burden, research on this condition in Central Asia remains scarce, especially among the Kazakh population. This study analyzes demographic characteristics, treatment outcomes, and procedural challenges associated with ICAS in 216 patients treated at a single institution.

Aim: Neurodegenerative diseases are characterized by early increased beta-amyloid (Aβ) and decreased cerebrovascular reactivity. We investigated Aβ in gingiva, serum or hippocampus and neurovascular reactivity in basilar artery (BA) of periodontitis rats, to test the impact of Aβ on BA vasoreactivity ex vivo.
Materials And Methods: Periodontitis was induced in 32 rats using silk-ligation.
Introduction This case report illustrates the complexities of arrhythmogenic right ventricular cardiomyopathy (ARVC) and its thromboembolic complications resulting in top-of-basilar artery syndrome. We discuss the case of a 37-year-old male with ARVC who presented with acute onset of dizziness, imbalance, and vomiting, leading to the diagnosis of a top-of-basilar artery occlusion which was successfully treated. Case presentation This case highlights the diagnostic and acute treatment challenges in basilar artery occlusion (BAO) due to its non-specific symptoms and emphasizes the critical role of CT angiography in detecting occlusive thrombi for timely intervention.

: Subarachnoid hemorrhage (SAH) is a life-threatening cerebrovascular condition that triggers a robust inflammatory response and cerebral vasospasm. This study aimed to evaluate the effects of anakinra, an interleukin-1 receptor antagonist, and tocilizumab, an interleukin-6 receptor antagonist, on inflammation and vasospasm in an experimental rat SAH model. : Forty male Sprague Dawley rats (200-250 g) were randomly assigned to five groups: control, SAH, SAH + anakinra (ANA), SAH + tocilizumab (TCZ), and SAH + anakinra + tocilizumab (ANA+TCZ).
