View clinical trials related to Compartment Syndrome of Leg.
Filter by:Compartment syndrome (CS) is a condition where an increase in pressure in an anatomical compartment (e.g. the lower leg) affects the blood supply of the tissues, leading to tissue damage. The condition is difficult to diagnose, and more difficult to determine when and how to manage it. Treatment aims to reduce the pressure in the compartment by whatever means possible. Surgical management by of CS is highly invasive and has associated risks including infection, damage to local structures (i.e. nerves), and possibly the inability to close the wound leading to the need for further reconstructive procedures. The clinical challenge in suspected CS is knowing if and when to intervene. Some cases of mild CS may resolve without an operation, and therefore intervening too soon causes unnecessary harm to the patient. However, waiting too long to operate with high compartmental pressures may lead to irreversible damage to the tissues, resulting in either a useless limb or necrotic tissue needing amputation. Current strategies for determining limb health include interrogation of symptoms, signs on examination, and serial measurements of compartmental pressures, but no absolute measurement of tissue health. As such, there is an element of clinical judgment in management and no evidence base with which to develop clear treatment guidelines. There is a need for a minimally invasive method of continuously monitoring tissue health to improve the understanding of CS and its management before significant improvement in patient outcomes can be delivered. It is proposed the application of leg "microfluidics" - analysis of samples of leg fluid - in a series of predictable clinical scenarios which simulate the threatened and unsalvageable limb. This is with an ultimate aim of developing a method of limb fluid sampling that can predict if CS is present and requires intervention.
Acute compartment syndrome (ACS) is a surgical emergency that can develop in patients on extracorporeal membrane oxygenation (ECMO). ACS is a type of limb ischemia, which means that the limb, such as the arm or leg, loses blood flow. Patients on ECMO can develop this condition for many reasons, but most commonly from the ECMO procedure itself. This most commonly involves the leg. Key symptoms of ACS include severe pain, loss of pulses, loss of feeling, and inability to move the limb. However, because patients on ECMO are often sedated, ACS is difficult to diagnose as patients can not report symptoms. As a result, the only available tool for diagnosing ACS may be measurement of pressures in the limb. This is normally done with a needle-device, which is inserted into the leg for a single measurement. However, a recently developed device, called the MY01 Continuous Compartment Pressure Monitor, allows for continuous pressure readings instead of a single measurement. Multiple measurements may allow for much greater accuracy in diagnosing ACS, which may result in faster time to surgery and potentially save more limbs than single measurements. This device may also be less invasive than an older method of continuous pressure measuring, which uses a needle and tubing that is 14-gauge in size. Therefore, this study aims to compare 3 different types of methods for diagnosing ACS in patients on ECMO, which are 1) Standard of Care, 2) Standard of Care and MY01, and 3)Standard of Care and 14-gauge slit catheter.
Chronic Exertional Compartment Syndrome (CECS) is a painful condition affecting runners and it is caused by a reversible increase in pressure within a closed compartment in the leg. Currently, to diagnose CECS, a large needle is placed into the muscle to measure pressure, which is invasive and painful. After diagnosis, the gold standard of treatment is surgery, which is also invasive, involves a prolonged return to play, and has a significant number of treatment failures. A growing literature has suggested alternative methods to both diagnosis and treatment that include the use of ultrasound to investigate muscle stiffness with shear wave elastography (SWE), and treatment with botulinum toxin injection into the muscle. The investigators propose a single-site randomized clinical trial to investigate the use of abobotulinumtoxinA in the treatment of CECS. Researchers also look to develop a non-invasive method for the diagnosis of CECS using SWE. To the researchers' knowledge, this is the first randomized study investigating the medication to treat this cause. The study will take place at Emory's outpatient sports medicine clinic. Potential participants will primarily be identified and recruited from the departments of Physical Medicine and Rehabilitation, Orthopedics, Physical Therapy, and Sports medicine as a part of regular clinical care. Participants will be included in the randomized portion of the study if they meet the previously established diagnostic criteria for CECS with compartmental pressure testing. This would be a landmark study to provide evidence for the use of an abobotulinumtoxinA in the treatment of CECS, leading to the potential avoidance of a surgical procedure. It could also change the means of diagnosis without the use of painful and invasive needle pressure testing that would provide patients and athletes with ease of care.
Acute compartment syndrome (ACS) after revascularization for acute limb ischemia is a potentially limb-threatening condition and requires urgent fasciotomy. Compression ultrasound (CU) is an established method for measuring intravenous pressure in superficial veins and, for example, can determine central venous pressure in critically ill patients. In cadaver studies, compression ultrasound has been proven to correlate with invasive intra compartmental pressure (ICP) measurements. This study aims to determine CU's added diagnostic value compared to ICP in detecting ACS after revascularisation.
