Clinical trials

Aneurysmal subarachnoid hemorrhage (aSAH) is a life-threatening cerebrovascular emergency with high mortality and disability rates. Despite advances in neuroimaging and interventional techniques, outcomes remain poor for many patients due to complex post-rupture complications such as delayed cerebral ischemia (DCI), pneumonia, and other systemic injuries. These secondary events critically affect neurological recovery, yet their molecular mechanisms are not fully understood. This multicenter study aims to investigate the biological basis of post-rupture complications and prognosis in patients with aSAH through integrated multi-omics and clinical data analysis. Biospecimens including blood, cerebrospinal fluid, urine, and other relevant tissues will be collected for genomic, transcriptomic, proteomic, metabolomic, and imaging-omic profiling. By linking molecular data with clinical and imaging indicators, the study seeks to identify key pathways and biomarkers associated with secondary injury and outcome heterogeneity.

Acute hemorrhagic stroke is a series of neurosurgical diseases characterized by bleeding with high morbidity and mortality. It accounts for about 20% of all strokes worldwide and mainly includes subtypes such as intracerebral hemorrhage (ICH) and subarachnoid hemorrhage (SAH). Multimodal computed tomography including non-contrast computed tomography, computed tomography angiography and computed tomography perfusion, is of great important in understanding pathophysiological changes, evaluating prognosis and guiding interventions in these diseases.
