Splenic Artery Syndrome as a Possible Cause of Late Onset Refractory Ascites After Liver Transplantation: Management With Proximal Splenic Artery Embolization

摘要

Background. Portal hyperperfusion (PHP) is a hemodynamic condition which may develop after liver transplantation and cause refractory ascites (RA). The diagnosis is established by exclusion of other causes of increased sinusoidal pressure/resistance such as cellular rejection or toxicity and outflow obstruction. PHP as part of the pathogenesis of the splenic artery syndrome (SAS) can be treated with splenic artery embolization (SAE).
