Pressure-sensing sheath monitoring during neuroendovascular procedures

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a prospective, single-center observational study enrolling 50 adult patients undergoing elective transradial neuroendovascular procedures requiring continuous invasive blood pressure monitoring. Blood pressure will be recorded simultaneously using three methods during the procedure: a pressure-sensing sheath, a standard radial arterial line, and a non-invasive cuff. The primary outcome is the accuracy of the sheath measurements compared with the radial arterial line, with secondary outcomes including access site complications, procedure duration, patient comfort, and cost-effectiveness. Results will be analyzed to compare agreement between methods and to document safety and workflow implications.
