Blood flow in the brain when sitting up

We are currently conducting a study at the USZ in which we are examining both stroke patients and people who have not suffered a stroke.

Aim of the study

A stroke is often caused by a blood clot that blocks a vessel in the brain. In many cases, this clot is surgically removed as quickly as possible. After the clot has been removed, there is a possibility that too much blood will flow through the open vessel into the brain, which could cause further problems. We would like to investigate whether this phenomenon can be counteracted by raising the affected person upright after the clot has been removed instead of leaving them lying flat in the hospital bed for a longer period of time. For a better understanding, we would also like to investigate how the blood flow of unaffected persons reacts to such an uprighting of the body.

Who can take part?

You must be over 65 years old and not have suffered a stroke or cerebral hemorrhage.

Procedure

You will be placed on a bed with which we can bring you into an upright position. You will wear special glasses during the examination. The eyeglass frame is used to hold an ultrasound probe on your temple, which can be used to monitor the blood flow of a specific cerebral artery (non-invasive). The examination takes about one hour (+ approx. 30 minutes preparation time). Three months after the examination, we will call you to find out how you are doing.
