About
Sinusoidal obstruction syndrome (SOS) is a potentially fatal hepatic veno-occlusive disease-affecting children following bone marrow transplantation (BMT). SOS most likely develops secondary to sinusoidal endothelial damage and subsequent obstruction. The disease can be separated into mild, moderate, and severe forms; almost all patients diagnosed with severe SOS will die from this disease. Children with severe SOS suffer from multi-organ failure with signs and symptoms of portal hypertension (ascites, varices, edema), renal and respiratory failure . Although these children may be few and far between, the mere severity of the disease process and awful prognosis factors are valid reasons for more medical attention. SOS is usually diagnosed via clinical criteria and, despite available prophylaxis and treatment, children continue to die from this devastating disease.
Quantitative shear wave ultrasound elastography with acoustic force radiation imaging is an emerging technology that uses ultrasound pressure waves to provide an estimate of tissue stiffness. This technique is promising for pediatric imaging because it is portable, quick to perform, relatively low cost and involves no ionizing radiation. Acoustic force radiation imaging and ultrasound elastography does not have any increased risks over conventional ultrasound imaging.
Full description
This is a single site prospective cohort study that will compare ultrasound elastography to traditional ultrasound parameters in bone marrow transplant patients who are at risk for development of SOS.
