Intra-operative Evaluation of the External Ventricular Drain Catheter Position With Structured Light for Patients (Bullseye EVD)
Trial Parameters
Brief Summary
The placement of external ventricular drainage (EVD) is a life-saving procedure used to relieve high pressures in the brain. Often performed at the bedside, a small tube (catheter) is inserted into one ventricle of the brain to drain cerebrospinal fluid and release the pressure build up. In standard practice, EVDs are placed freehand and initial catheter malpositioning occurs in up to \~60% of procedures. Currently, there are no adequate means to verify the position of the catheter before insertion which is a significant impediment to ensure accurate positioning. This non-interventional study aims to validate a novel technology, Bullseye EVD, for verifying the position of the EVD catheter during these emergency procedures.
