Clinical Trial Summary

This study involves using a augmented reality (AR) system to assist in the placement of a subdural evacuating portal system (SEPS). In the first part of the study, all participants will have skin marking of an AR-guided and non-AR-guided site to determine feasibility and method accuracy. In the second part, subjects will be randomized to AR-guided and non-AR-guided SEPS placement to determine efficacy.

Description:

Chronic/subacute subdural hematoma (SDH) is one of the most common diseases encountered in neurosurgical practice. However, there is little consensus on first-line treatment. The SEPS was developed to implement a minimally invasive approach to drainage. New imaging technologies, such as augmented reality (AR) interfaces, can provide anatomical models and can help visualize hidden structures. The hope is that this study can give insight on whether AR-guidance can be used to improve SEPS placement, which can lead to higher volume drainage, greater symptomatic improvement, and decreased hospital stay.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Mean accuracy (in mm) of SEPS placement	Comparison of measurements obtained by standard of care surface measurements and placement using AR guidance, and post placement CT scans.	Intra-procedural and up to 24 hours post procedure
Secondary	Change in size (mm) of subdural hematoma	Radiographic measure of thickest hematoma volume in sagittal and coronal planes after subdural evacuation compared to pre-procedure imaging, assessed in the randomized AR-guided and non-AR-guided arms only.	Pre-procedure and 24 hours after SEPS placement
Secondary	Change in symptom score	Composite measure, scaled from 0 (no symptoms) to 10 (severe symptoms), scored by clinician based overall impression of objective and subjective signs and symptoms including neurological strength exam, cognitive status, and patient self-reported symptomatic change, assessed in the randomized AR-guided and non-AR-guided arms only.	Assess at 24 hours status post SEPS placement and again at 1 month
Secondary	Length of hospital stay	Number of days since procedure between SEPS placement and discharge from inpatient stay, assessed in the randomized AR-guided and non-AR-guided arms only.	Approximately 2 to 5 days
