Evaluating cerebral blood flow using a new method from angiography
The Association Between a New Parameter Derived From DSA and Outcomes in Cerebral Ischemia
Xi'an No.3 Hospital · NCT03607565
This study is trying to see if a new way of looking at brain blood flow from angiography can help predict recovery in patients who have had a stroke caused by blocked blood vessels.

What this trial studies
This observational study aims to assess a new parameter derived from Digital Subtraction Angiography (DSA) to evaluate cerebral perfusion in patients with cerebral ischemia. By analyzing DSA images and correlating them with patient outcomes measured by the modified Rankin Scale, the study seeks to establish a relationship between this new parameter and the prognosis of acute stroke with large vessel occlusion. The research focuses on retrospective data analysis of patients who have undergone DSA to better understand cerebral blood flow dynamics.
Who should consider this trial
Good fit: Ideal candidates for this study are patients diagnosed with cerebral ischemia who have undergone Digital Subtraction Angiography.
Not a fit: Patients with cerebral hemorrhage will not benefit from this study as they do not meet the inclusion criteria.
Why it matters
Potential benefit: If successful, this study could improve the prediction of outcomes for patients suffering from acute stroke due to large vessel occlusion.
How similar studies have performed: While the approach of using DSA-derived parameters is established, the specific application of this new parameter in predicting outcomes in cerebral ischemia is novel and has not been extensively tested.
