OBJECTIVE: The aim of the study was to investigate the utilization of contrast-enhanced ultrasound (CEUS) for the detection of splenic artery steal syndrome (SASS) after orthotropic liver transplantation (OLT). MATERIALS AND METHODS: A total of 247 patients underwent OLT. The blood tests and color Doppler flow imaging (CDFI) were performed at various time points post-operatively. CEUS and celiac angiography were conducted in patients suspected of SASS. If the diagnosis of SASS was confirmed, splenic artery embolization was performed to enhance hepatic artery flow. CEUS and angiography were performed for assessment of post-interventional clinical outcomes. RESULTS: Among 247 patients, 3 patients died post-operatively, and 8 patients were suspected of SASS by elevated liver enzyme levels and slim or undetectable hepatic arterial Doppler blood signals by CDFI at various time points post-operatively. CEUS in 8 patients showed a delayed and weak contrast-enhanced blood signal in the hepatic artery associated with a rapid and intense enhancement of portal venous blood. No narrowing of a hyperintense signal was observed in the hepatic artery by CEUS. The 8 diagnoses of SASS were proven by celiac angiography that showed delayed perfusion of the hepatic artery and rapid filling of the splenic artery. Immediately after the interventional procedure, CEUS demonstrated a significantly enlarged hyperintense blood signal in the hepatic artery. CONCLUSION: Approximately 3.27% of SASS occurs after OLT. SASS is identified as a sluggish and weak hyperintense blood signal in the hepatic artery without the narrowing and interruption of hypeintense signal in CEUS. CEUS is an effective imaging modality for detection of SASS following OLT. © 2012 American Association for the Study of Liver Diseases. |
