Hypothesis
Can preoperative CT perfusion parameters predict the risk of post-revascularization cerebral infarction in adults with moyamoya disease?
Conclusion
Preoperative mean Tmax values greater than 3.590 seconds indicate a higher risk of post-revascularization cerebral infarction in adults with moyamoya disease.
Supporting Evidence
- Post-CI occurred in 11 patients (12.0%).
- Preoperative mean Tmax was identified as an independent predictor of post-CI.
- Patients with infarction within 2 months before surgery had a higher risk of post-CI.
- The preoperative mean Tmax produced the largest area under the curve (0.955).
- Sensitivity for predicting post-CI was 100% with a specificity of 87.7%.
Takeaway
Doctors can use special brain scans to see if patients with moyamoya disease are likely to have a stroke after surgery. If a number is too high, it means they might be at risk.
Methodology
This retrospective study analyzed preoperative CT perfusion parameters in 92 adults with moyamoya disease who underwent surgical revascularization.
Potential Biases
The retrospective nature of the study may introduce bias in patient selection and data interpretation.
Limitations
The study had a single-center design and a relatively small sample size, which may lead to selection bias.
Participant Demographics
The study included 92 adults (49 women, 43 men) with a mean age of 49.7 years.
