AI Article Synopsis
- A patient had a subarachnoid hemorrhage caused by a dissecting aneurysm in the right posteroinferior cerebellar artery (PICA), which was successfully treated.
- The patient, a 48-year-old with high blood pressure, was diagnosed with hemorrhage via CT scan and showed changes in the aneurysm's structure through cerebral angiography.
- During surgery, an encircling clip was used to reconstruct the aneurysm while preserving blood flow to critical areas of the brain, resulting in a successful treatment outcome.
Article Abstract
Objective And Importance: We present a patient who experienced a subarachnoid hemorrhage secondary to a dissecting aneurysm of the right posteroinferior cerebellar artery (PICA). The use of an encircling clip in treating the aneurysm while preserving supply to brain stem perforators originating near the dissecting segment and the distal PICA territory was key in the operative management.
Clinical Presentation: A 48-year-old patient with a history of hypertension presented with subarachnoid hemorrhage confirmed by computed tomography of the brain. Successive cerebral angiography revealed a dynamic change in the configuration of the dissection, with expansion of the associated focal ectasia.
Operative Management: At surgery, three brain stem perforators adjacent to the aneurysm were visualized. The dissecting segment was reconstructed with an encircling Sundt clip and muslin wrap, which preserved the flow through the PICA and brain stem perforators.
Conclusion: A patient suffering from a dissecting PICA aneurysm and subarachnoid hemorrhage was successfully treated with direct surgical reconstruction of the parent artery, sparing the perforators to the medulla.

Background: Surgical clipping and endovascular coiling are both effective in preventing aneurysmal subarachnoid hemorrhage, but the choice between these interventions remains controversial, leading to treatment disparities across medical centers.
Methods: A systematic review and meta-analysis were conducted, including relevant two-arm clinical trials up to September 2023, sourced from Scopus, PubMed, Web of Science, and the Cochrane Library. Our primary outcomes were complete occlusion rates during mid-term and long-term follow-ups.

Subarachnoid hemorrhage (SAH) is a type of hemorrhagic stroke with high morbidity, mortality and disability, and early brain injury (EBI) after SAH is crucial for prognosis. Recently, stem cell therapy has garnered significant attention in the treatment of neurological diseases. Compared to other stem cells, dental pulp stem cells (DPSCs) possess several advantages, including abundant sources, absence of ethical concerns, non-invasive procurement, non-tumorigenic history and neuroprotective potential.

To study the risk of incident dementia after a non-traumatic intracranial hemorrhage in a diverse US population, and evaluate if this risk is different for the subtypes of intracranial hemorrhage. We performed a retrospective cohort study using both inpatient and outpatient claims data on Medicare beneficiaries between January 1, 2008 and December 31, 2018. The exposure was a new diagnosis of non-traumatic intracranial hemorrhage, defined as a composite of intracerebral hemorrhage (ICH), subarachnoid hemorrhage (SAH), and subdural hemorrhage (SDH).
