STEM Trial Summary

This trial is designed to see if a new treatment for chronic subdural hematoma (a buildup of blood on the brain) is safe and effective.

Who is the study for?
The STEM trial is for adults aged 30 or older with chronic subdural hematoma (cSDH) that's at least 10 mm thick and causing brain pressure. Participants must have had a stable condition before the cSDH, be experiencing symptoms like headaches or weakness, and commit to follow-up visits. Pregnant women can't join, nor can those who've had certain prior head surgeries or conditions affecting the brain.Check my eligibility
What is being tested?
This study compares different treatments for cSDH: SQUID embolization alone, SQUID plus surgery, standard surgery alone, and medical management without surgery. Patients are randomly assigned to these groups in equal numbers to test safety and effectiveness of MMA embolization with SQUID.See study design
What are the potential side effects?
Possible side effects include discomfort at the catheter insertion site, allergic reactions to contrast dye used during embolization (if not medically managed), bleeding complications from surgical procedures, infection risks post-surgery, and general anesthesia risks.
