SHAPE of Portal Hypertension in Children
Sponsored by Thomas Jefferson University
About this study
Early diagnosis of portal hypertension is difficult as symptoms rarely manifest until the later stages of liver disease. Both cirrhotic and non-cirrhotic portal hypertension can result in life-threatening complications, the most frequent of which is bleeding from esophageal varices. In children, variceal bleeds are associated with mortality rates of 1-3 %, while life-threatening complications have been reported in up to 20 % of children with cirrhosis. Despite the high incidence of portal hypertension in children with liver disease, a noninvasive modality to monitor disease progression and risk of complications is currently lacking. Hence, this trial will investigate the safety and efficacy of subharmonic aided pressure estimation (SHAPE) as a noninvasive ultrasound technique for diagnosing portal hypertension in children.
