A New Parameter Derived From DSA to Evaluate Cerebral Perfusion

Recruiting

• Conditions: Cerebral Ischemia

• Registration Number: NCT03607565
• Lead Sponsor: Xi'an No.3 Hospital

Brief Summary

This observational study focus on a new parameter of cerebral perfusion derived form digital substraction angiography.

Detailed Description

Ischemic cerebrovascular disease is an important cause of death and disability in the world. Digital Subtraction Angiography (DSA) is the golden index for evaluating cerebral blood vessels. We introduced a new parameter derived from DSA to evaluate the perfusion to predict the outcomes in acute stroke with large vessel occlusion.

To study the possible relationship between the new parameter of cerebral perfusion derived from DSA and outcomes in cerebral ischemia（modified Rankin Scale）, we intend to retrospectively analyze the images derived from patients who undergone the DSA and follow-up outcomes（modified Rankin Scale）.
