ClinConnect Summary

This clinical trial is looking at a new way to see blood flow in the brain during surgery using a technique called laser speckle contrast imaging. The goal is to help neurosurgeons get a real-time view of how blood is flowing, which can be crucial for preventing complications like strokes during procedures for conditions such as brain aneurysms or arteriovenous malformations. Unlike the current method that uses a special dye and can only be done a few times, this new technology does not require any dye and can provide continuous images of blood flow.

To participate in the trial, you need to be an adult (18 years or older) and have a surgical procedure that involves a craniotomy (a type of surgery where part of the skull is removed) that is at least 2 centimeters in size. You should also be able to provide written consent to take part. If you have difficulty with understanding or making decisions, or if you can't give consent legally, you would not be eligible for this study. Participants will have the opportunity to help researchers compare this new imaging technique with the standard method used in surgeries, potentially contributing to better surgical outcomes in the future.
