Chronic Subdural Hematoma Treatment With Embolization Versus Surgery Study

The goal of this clinical trial is to test in moderately symptomatic chronic subdural hematoma (CSDH) patients if middle meningeal artery embolization (MMAE) can be used as an alternative to conventional open surgery. The main questions it aims to answer are:

• Compared to open conventional surgery, does MMAE reduce the need for rescue surgery or deaths?

• What is the safety of MMAE and conventional open surgery in these patients?

Participants will be asked to:

• Share their medical history and undergo physical examinations

• Have blood drawn

• Have CT scans of the head

• Answer questionnaires

• Undergo MMAE or conventional open surgery Provide information about possible adverse events Researchers will compare participants in the MMAE group with those in the conventional open surgery group to see if there is a reduced need for rescue surgery or deaths and evaluate safety.
