Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The standard of care for postoperative hematoma cavity monitoring is computed tomography (CT). However, repeat CTs to assess patients with ICH incur health and financial cost including time and personnel to bring the patient to scan, risk of dislodging lines or drains, radiation dosing, and financial cost as well as others. Studies have demonstrated varying degrees of efficacy when using transcranial ultrasound to measure ICH volume. Recently, synthetic implants for cranioplasty have been shown to be safe and sonolucent. This study aims to evaluate the ability of transcranial ultrasound with sonolucent cranioplasty (TUSC) to detect and quantify bleeding in postoperative ICH patients.
In this prospective study, postoperative ICH patients will undergo cranioplasty with a sonolucent polymethyl methacrylate implant and serial monitoring via TUSC. Whenever a CT is performed during business hours, TUSC will be performed within 2 hours by a neurointensivist trained in point-of-care transcranial ultrasound (TCUS). Imaging will be reviewed by two independent neuroimaging experts. Additional secondary outcomes will include occurrence of serious adverse events, detection of intraventricular hemorrhage, and cost of care when compared to CT.
This work has the potential to significantly improve clinical management of ICH. This study will provide the safety and feasibility data necessary to guide future clinical research. ICH detection and volumetry are critical to patient care and prognostication. This point-of-care testing enables neurosurgeons to serially monitor patients to ensure that they receive timely, appropriate care.

Study Groups

transcranial ultrasonography through sonolucent cranioplasty
All surgical procedures and implants in this protocol are standard of care.
ClearFit implant
The ClearFit implant is an FDA cleared implant in regular use in the United States. The ClearFit implant and other PMMA cranioplasty implants manufactured by Longeviti have been reported to be safe and effective as cranial implants that permit transcranial ultrasound to be performed. The PMMA cranioplasty implant (Longeviti Neuro Solutions, Hunt Valley, MD) is clear, sonolucent, and was recently shown to be safe and effective in transcranial ultrasonography for bypass patency assessment. The ClearFit cranioplasty being used in this study is industry standard of care.
transcranial ultrasonography through sonolucent cranioplasty
The implantation of the ClearFit PMMA sonolucent implant permits TUSC to be performed at the bedside for patients in both the in-patient and outpatient settings. While the patient is an inpatient, the clinical or research teams will attempt to perform TUSC within 1 hour of neuroimaging if that neuroimaging is performed at a time when a trained ultrasound operator is present.
