Background: the aim of this study was to assess and to compare the ability of intrathecal nicergoline and nimodipine in prevention of cerebral vasospasm in a rabbit model of subarachnoid hemorrhage (SAH).
Method: twenty male New Zealand white rabbits were allocated into four groups randomly. Subarachnoid hemorrhage was induced by injecting autologous blood into the cisterna magna. The treatment groups were as follows: (1) control [no SAH (n = 5)], (2) SAH only (n = 5), (3) SAH plus nimodipine (n = 5), and (4) SAH plus nicergoline (n = 5).
Findings: there was a statistically significant difference between the mean basilar artery cross-sectional areas and the mean arterial wall thickness measurements of the control and SAH-only groups (p < 0.05). Basilar artery vessel diameter and luminal section areas in group 3 were significantly higher than in group 2 (p < 0.05). Basilar artery vessel diameter and basilar artery luminal section areas in group 4 were significantly higher than in group 2 (p < 0.05). There was no significant difference between basilar artery vessel diameter and basilar artery luminal section areas in group 3 and group 4.
Conclusions: these findings demonstrate that intrathecal nicergoline has a vasodilatatory effect in an experimental model of SAH in rabbits but not more than that of nimodipine.

Basilar artery perforator aneurysms (BAPAs) are rare and may be occult on initial imaging due to their small size and susceptibility to intermittent thrombosis.1 2 Conventional treatments for aneurysms (eg, clipping or coiling) have proved challenging.3 Recently, endovascular electrocoagulation has been shown to be effective for BAPAs.

Purpose: To describe a novel alternative technique for C2 fixation under the concept of atlantoaxial joint distraction and fusion with intra-articular Cages, and to report its preliminary clinical outcomes.
Methods: Eighteen patients with basilar invagination and atlantoaxial dislocation underwent atlantoaxial joint distraction and fusion with intra-articular Cages. All patients had hypoplasia of the C2 isthmus prohibiting insertion of the pedicle screw.
Background: Intracranial atherosclerotic stenosis is a leading cause of ischemic stroke and recurrent events due to plaque instability. High-resolution magnetic resonance imaging identifies plaque enhancement as a key marker of instability. This study evaluated the efficacy of combined high-intensity statins and proprotein convertase subtilisin/kexin type 9 inhibitors in plaque stabilization.

Objectives: Mechanical thrombectomy (MT) has revolutionized the treatment of acute ischemic stroke (AIS). Still, the efficacy and safety in patients older than 85 years of age are not conclusive by the present randomized controlled trials' data (RCT). Aging is a multifactorial process and the impact of MT on this specific population needs to be further analyzed.

Objectives: To assess the efficacy of endovascular treatment and clinical outcomes in individuals with symptomatic intracranial stenosis who had not responded adequately to medical intervention.
Methods: The study included 32 patients who received endovascular treatment due to high-grade (70%-99% severity) intracranial atherosclerotic stenosis from December 2021 to December 2023. The patients had not experienced any acute ischemic or hemorrhagic infarction within the last three weeks, had a Modified Rankin Scale score of ≤3 at baseline, and developed a transient ischemic attack or non-disabling stroke despite having received the best medical treatment.
