Conditions

Cerebral Ischemia

Outcome Measures

Primary Outcomes (1)

  • the outcomes between good perfusions and poor perfusions

    Results are reported as odds ratios (ORs) with 95% confidence intervals (CIs).

    3 months to 2 years

Secondary Outcomes (1)

  • the outcomes between good perfusions and middle perfusions

    3 months to 2 years

Study Arms (3)

good perfusion in DSA

We introduced a new parameter derived from DSA to evaluate the perfusion in cerebral ischemia.(good perfusion)

middle perfusion in DSA

We introduced a new parameter derived from DSA to evaluate the perfusion in cerebral ischemia.(middle perfusion)

poor perfusion in DSA

We introduced a new parameter derived from DSA to evaluate the perfusion in cerebral ischemia.(poor perfusion)
