This is a prospective, randomized vanguard trial of trauma patients admitted to the trauma surgery service at Intermountain Medical Center who are deemed to be at high risk for venous thromboembolism. Once identified and enrolled, subjects will be randomized to receive bilateral lower extremity duplex ultrasound surveillance versus no surveillance. The study will compare the two groups with regard to deep vein thrombosis, pulmonary embolism, and major bleeding episode rates, both during the index hospitalization and at 90 days post-discharge.

This study evaluates the use of ultrasound simulators for retaining and improving ultrasound skills acquired in undergraduate ultrasound training.
Surveillance of drugs, devices, appliances, etc., for efficacy or adverse effects, after they have been released for general sale.
The use of ultrasound to guide minimally invasive surgical procedures such as needle ASPIRATION BIOPSY; DRAINAGE; etc. Its widest application is intravascular ultrasound imaging but it is useful also in urology and intra-abdominal conditions.
Tissue ablation of the PROSTATE performed by ultrasound from a transducer placed in the RECTUM. The procedure is used to treat prostate cancer (PROSTATIC NEOPLASMS) and benign prostatic hypertrophy (PROSTATIC HYPERPLASIA).
Telephone surveys are conducted to monitor prevalence of the major behavioral risks among adults associated with premature MORBIDITY and MORTALITY. The data collected is in regard to actual behaviors, rather than on attitudes or knowledge. The Centers for Disease Control and Prevention (CDC) established the Behavioral Risk Factor Surveillance System (BRFSS) in 1984.
Ultrasonography applying the Doppler effect, with frequency-shifted ultrasound reflections produced by moving targets (usually red blood cells) in the bloodstream along the ultrasound axis in direct proportion to the velocity of movement of the targets, to determine both direction and velocity of blood flow.

Surgery is a technology consisting of a physical intervention on tissues. All forms of surgery are considered invasive procedures; so-called "noninvasive surgery" usually refers to an excision that does not penetrate the structure being exci...
Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
