Brief Summary:

This study investigates the ability of ultrasound to measure the volume of a brain hemorrhage in the acute phase after hospital admission.

It is known that approximately 30% of patients admitted with a brain hemorrhage will suffer from enlargement of the hematoma within the first hours after admission.

In this study the investigators measure the volume of the hematoma every 30 minutes up to 6 hours after admission and every 2 hours between 6-12 hours.

Condition or disease
Stroke Cerebral Hemorrhage

Detailed Description:

This study investigates the use of transcranial ultrasound (TCU) for the surveillance of patients with intracerebral hemorrhages. Using transcranial ultrasound makes it possible to visualize and follow the bleeding progression through 3 points of the scull where the bone is thin enough to allow the penetration of sound waves. This can be done at bedside. Today the investigators do not know for sure if clinical parameters determine a haematoma expansion. TCU will allow us to follow the haematoma progression serially in the acute phase and relate the haematoma expansion to parameters like blood pressure, neurological status (NIHSS-score) and radiological signs of ongoing bleeding (spot signs) on CT-angiogram (CTA).


  1. Bedside ultrasound volume assessment is accurate in estimating the haematoma volume compared to computer tomography (CT) and can dynamically document the haematoma expansion.
  2. The haematoma expansion is accompanied by neurological deterioration and happens only with patients with CT demonstrated spot signs.
  3. The haematoma expansion is observed with patients with high blood pressure.

Aim of study:

  1. To validate the accuracy of ultrasound (US) compared to CT in estimating haematoma volume with ICH patients.
  2. To measure ICH volume serially in the acute phase using US and up to 12 hours aiming at:

    • Describing the timing of the haematoma expansion.
    • Relating to neurological deterioration, systemic blood pressure and detection of spot signs on CTA.
