Objective: Cerebral proliferative angiopathy (CPA) is a rare disease, characterized by a large vascular nidus, diffuse angiogenesis, and intermingled normal brain tissue. Conservative treatment, endovascular intervention, indirect revascularization, and radiotherapy have been applied to treat this disease. However, some cases deteriorate even after non-conservative treatment, and there has been no standard of treatment for this disease so far. In order to build a better treatment strategy, we review literature, present our case and propose an algorithm for managing CPA.
Methods: Following the PRISMA principle, we systemically reviewed literature discussing CPA. A case successfully managed with multi-modal treatment is also illustrated.
Results: A total of 23 articles with 74 cases of CPA were found. Thirty-three patients received single-modal management. These 33 cases include 24 receiving endovascular intervention, 7 receiving indirect revascularization, and 2 receiving radiotherapy. Three of the 33 patients deteriorated clinically, and 1 expired. We present a 6-year-old boy with left hemispheric CPA receiving indirect revascularization, followed by 2 consecutive courses of stereotactic radiosurgery targeting arteriovenous shunts in the left basal ganglia and arteriovenous shunts around the olfactory groove. In the follow-up period of more than 4 years, good collateral formation, improved perilesional perfusion, CPA shrinkage, and symptom relief were all achieved.
Conclusions: Based on our literature review and case, we propose an algorithm for the management of CPA and emphasize that multi-modal treatment is necessary for most CPA cases.

Background: Delirium in the post-anesthesia care unit (PACU) may be associated with worse outcomes in children with moyamoya disease (MMD). This retrospective study aimed to describe the prevalence of PACU delirium in children with MMD and investigate its risk factors.
Methods: Patients with MMD aged < 15 years who underwent indirect revascularization between January 2014 and October 2023 were included in this study.

Treating ruptured aneurysms in deep collateral arteries in moyamoya disease is difficult. Two cases of intracranial hemorrhage due to ruptured aneurysms in the deep collateral vessels after indirect revascularization for moyamoya disease were treated via direct surgery with the assistance of surgical simulation using three-dimensional computer graphics. The three-dimensional computer graphics provided detailed anatomical relationships between the aneurysm and the surrounding structures, which led to successful surgical results in both patients.

Objective: The aim of this research was to investigate the specific regulatory role of miR-6760-5p in angiogenesis in moyamoya disease.
Methods: HUVECs were transfected with miR-6760-5p inhibitor and mimics fragments, then subjected to assays for cell proliferation, migration, and tube formation. Subsequently, downstream target genes of miR-6760-5p were predicted and the protein expression levels of these genes were evaluated.

Primary percutaneous coronary intervention (PCI) is the cornerstone of treatment for ST-segment elevation myocardial infarction (STEMI). Previous studies suggest that direct transport by ambulance to a primary PCI facility is associated with better clinical outcomes in patients with STEMI. However, those studies included seriously ill patients for whom direct transport is the only option.
