Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Study overview: The data of the population in the MACTAHS study will be prospectively collected. The CT strategies for acute hemorrhagic stroke are mainly three categories: non-contrast computed tomography, computed tomography angiography and computed tomography perfusion. Each participants will be followed at least until 1 year after discharge. Finally, investigators will clarify the prognostic value of multimodal CT for patients with acute hemorrhagic stroke.

Sample size: About 10000 patients will be enrolled in this study. All the population will be expected to undergo non-contrast computed tomography, computed tomography angiography and computed tomography perfusion.

Study endpoints: Neurological functional outcomes, delayed ischemia and infarction, recurrent bleeding, cognition and emotional dysfunction, systemic in-hospital systemic complications, rehabilitation and recovery status will be evaluated and follow-up would be completed.
