ClinConnect Summary

This clinical trial is studying a technique called a brachial plexus block (BPB) to see how it affects patients undergoing a specific type of brain surgery called embolization for intracranial aneurysms. The surgery will be done using a method that accesses the arteries through the wrist (transradial approach). The researchers want to find out if using BPB can help reduce problems with the radial artery, which is the artery in the wrist, during and after the procedure. They will compare outcomes between patients who receive the BPB and those who do not.

To participate in this trial, you need to be between 18 and 75 years old and have a body mass index (BMI) under 28. You should be scheduled for elective surgery for an intracranial aneurysm and be able to give your consent to join the study. Participants will be monitored for any complications during the procedure and will have follow-up assessments to check the health of their upper limb arteries one month after surgery. It’s important to know that some people may not be eligible, such as those with allergies to local anesthetics or certain vascular conditions. If you decide to take part, the study will help doctors understand how to improve care during this type of surgery.
