Overview
Tab Title Description
Study type
ObservationalDescribes the nature of a clinical study. Types include:
- Observational study — observes people and measures outcomes without affecting results.
- Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
- Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.

About this study
Traumatic and non-traumatic soft tissue hematomas are frequently encountered in the acute care setting. The incidence of these hematomas appears to be on the rise secondary to the increased use of anticoagulants among older patients for a variety of medical conditions. The management of soft tissue hematomas depends on the accurate diagnosis of any ongoing bleeding as well as of identification of the injured vessel type. While the majority of cases can be managed conservatively, expanding hematomas leading to hemodynamic instability or ongoing blood loss might require embolization or surgical intervention. The mainstay diagnostic imaging modality is multidetector computed tomography (MDCT) with intravenous contrast that allows accurate assessment of hematoma size, location as well as evaluation for active extravasation. However, many patients cannot undergo CT imaging due to underlying kidney disease, allergy to contrast, or due to concerns for radiation exposure, especially in young age. Currently there are no alternative tests for these patients with a similarly high diagnostic accuracy available. This study intends to establish an imaging protocol and investigate the utility of contrast-enhanced ultrasound (CEUS) in the diagnostic work-up of soft tissue hematoma as an ionizing radiation-free alternative to computed tomography (CT) that can be used independent from the kidney function of the patient.
Participation eligibility
Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.
Inclusion Criteria:
- Adult patients over the age of 18 who have a clinical suspicion of an actively bleeding soft-tissue hematoma as determined by the treating emergency provider. Enrollment will be for one year or until a target of 20 patients is enrolled.
Exclusion Criteria:
- The investigators will exclude persons under the age of eighteen, vulnerable populations (pregnant patients and prisoners), need for immediate procedural intervention and those with known hypersensitivity to sulfur hexafluoride lipid containing microspheres as well as those who have a soft-tissue hematomas that are in an unfavorable anatomical location for ultrasound imaging.
