Image-Guided EVD Placement for Brain Conditions
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to determine if the Stryker Nav3 image guidance system improves the placement of external ventricular drains (EVDs) in the brain compared to the traditional free-hand method. EVDs relieve pressure from fluid buildup in the brain, which can occur due to various brain conditions. Participants will have their EVD placed either using the standard free-hand method or with the Nav3 system. The trial seeks individuals who need an EVD and have a head CT scan (a type of brain imaging) available before the procedure. As an unphased trial, this study offers participants the chance to contribute to advancing medical techniques for brain procedures.
Do I need to stop my current medications for the trial?
The trial information does not specify whether you need to stop taking your current medications.
What prior data suggests that the Stryker Nav3 image guidance system is safe for EVD placement?
Research shows that the Stryker NAV3 image guidance system safely places external ventricular drains (EVDs). EVDs are small tubes inserted into the brain to drain fluid. Studies indicate that using image guidance for EVD placement takes no more time than the traditional free-hand method. It often requires fewer attempts to position the tube correctly, reducing the risk of complications.
No evidence suggests that image guidance causes more issues than the free-hand method. In fact, it might even help prevent problems like tube blockages. Many doctors prefer image guidance, especially in more challenging cases. Overall, data suggest that the NAV3 system is well-tolerated and safe for patients needing EVD placement.12345Why are researchers excited about this trial?
Researchers are excited about using image-guided external ventricular drain (EVD) placement with the NAV3 System because it offers a new level of precision compared to the traditional free-hand method. Unlike the standard free-hand technique, which relies on a surgeon's experience and skill, the NAV3 System uses advanced imaging technology to guide the placement of the drain, potentially reducing the risk of complications. This could mean safer and more effective management of brain conditions that require EVD placement, leading to better patient outcomes.
What evidence suggests that the NAV3 system is effective for EVD placement?
Research has shown that using the Stryker Nav3 image guidance system for placing an external ventricular drain (EVD) is more accurate than the manual method. In this trial, participants will be assigned to one of two groups: one will receive EVD placement using the standard free-hand technique, while the other will receive EVD placement with the Stryker NAV3 image guidance system. Studies indicate that the image-guided method often requires fewer attempts and is more precise, ensuring more accurate tube placement in the brain, which can reduce complications. Additionally, using image guidance takes no more time than the traditional method. These findings suggest that image guidance might improve the overall success of EVD placement.12346

Are You a Good Fit for This Trial?
This trial is for patients who need an external ventricular drain (EVD) placed and can be safely assigned to either the image-guided or free-hand placement technique. They must have a recent head CT scan and give consent. It's not for those with very small or distorted ventricles, unstable conditions preventing a pre-EVD CT, needing immediate EVD without time for consent, or requiring ipsilateral EVD revisions.Inclusion Criteria
Exclusion Criteria
Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial
Treatment
Participants receive external ventricular drain placement using either the free-hand technique or the Stryker NAV3 image guidance system
Follow-up

What Are the Treatments Tested in This Trial?
Interventions
- Free Hand External Ventricular Drain Placement
- Image Guided External Ventricular Drain Placement Using the NAV3 System
Trial Overview
The study compares two methods of placing an EVD: one using the Stryker Nav3 image guidance system and the other using the standard free-hand technique. The goal is to see if the NAV3 system leads to better outcomes in positioning the drain.
