Predicting the Occurrence of Delayed Cerebral Ischemia Using Transcranial Doppler Ultrasou

168 patient records with subarachnoid hemorrhage and vasospasm who underwent emergency endovascular treatment. The dataset includes transcranial Doppler ultrasound measurements of cerebral blood flow, mean middle cerebral artery blood flow velocity, and the Lindegaard index to analyze factors influencing delayed cerebral ischemia. It was authored by JingQi Xu and last updated on 2026-05-09.

Use Cases

• Predicting delayed cerebral ischemia risk based on transcranial Doppler velocity thresholds mentioned in the description
• Analyzing the relationship between the Lindegaard index and clinical outcomes after subarachnoid hemorrhage
• Building classification models to identify severe vasospasm using mean blood flow velocity criteria
• Evaluating the predictive power of different hemodynamic parameters via ROC curve analysis as described

Strengths

• Contains data from 168 specific patient cases with confirmed conditions.
• Includes multiple quantitative hemodynamic parameters such as cerebral blood flow and the Lindegaard index.
• Clear clinical thresholds for mild-to-moderate (>120-150 cm/s) and severe (>150 cm/s) vasospasm are defined.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small, at 105.1 KB, indicating limited scope.
