ICH Expansion Risk Score

Estimate intracerebral hemorrhage (ICH) expansion risk using CT-angiography spot sign and clinical factors. The spot sign (contrast extravasation within hematoma on CTA) is the strongest predictor of hematoma expansion, associated with 3-6x higher expansion risk and worse outcomes. Guides hyperacute hemostatic therapy decisions.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Estimate intracerebral hemorrhage (ICH) expansion risk using CT-angiography spot sign and clinical factors. The spot sign (contrast extravasation within hematoma on CTA) is the strongest predictor of hematoma expansion, associated with 3-6x higher expansion risk and worse outcomes. Guides hyperacute hemostatic therapy decisions

Each component has a specific meaning:

  • CT-angiography spot sign — The ct-angiography spot sign recorded for the scenario being assessed.
  • Clinical factors — The clinical factors recorded for the scenario being assessed.

Note: Interpret the ich expansion risk result against the thresholds and context described above.

How to Use

Enter the CT-angiography spot sign, clinical factors for the scenario you are assessing. Estimate intracerebral hemorrhage (ICH) expansion risk using CT-angiography spot sign and clinical factors. The spot sign (contrast extravasation within hematoma on CTA) is the strongest predictor of hematoma expansion, associated with 3-6x higher expansion risk and worse outcomes. Guides hyperacute hemostatic therapy decisions. Use the ich expansion risk result to inform your calculation.
