6 cases of anastomotic stenosis distal PSV was significantly increased (PSV: 250 ± 102 cm/s), P < 0.01, Hepatic artery left tributary speed increased in some cases, mainly for the envelope is not see more smooth, the resistance index (RI) reduce (RI < 0.5), P < 0.01. Two false-positive cases mainly for lower RI < 0.5, The reason is moderate aortic stenosis after further examination; one missed cases without clear images of anastomotic, the left branch of the hepatic artery RI is normal, after further examination, we found the moderate aortic regurgitation caused sonographer

miscarriage of justice. Conclusion: Hepatic Hemodynamic checks help to find early hepatic artery complications after liver transplantation, but there are still some deficiencies, especially extrahepatic factors interfereing with the hemodynamic

parameters should caught clinicians attention.

Under supine resting state, ID-8 on the right elbow shallow intravenous bolus injection of ultrasound contrast agent (SonoVue) 1.5 ml, Siemens s2000, 4s-1 probe, scan mode at angiography, recording the whole process of enhanced and playback analysis arterial contrast agent arrival time, the superior mesenteric contrast agent filling process. Diameter stenosis is defined as: mild stenosis <50%; moderate stenosis of 50% to 75%; severe stenosis >75%. Moderate and severe stenosis is defined

as a clinically significant stenosis of the superior mesenteric artery. Results: CTA or DSA diagnose 52 cases of clinically significant stenosis. CEUS diagnose clinically significant stenosis 51 cases (17 cases with severe stenosis, moderate stenosis 34 cases), color Doppler ultrasound diagnosis of mesenteric artery stenosis diagnostic specificity and accuracy were 100%, 98.1%, respectively. CEUS diagnostic specificity and accuracy of arterial stenosis of the superior mesenteric artery were 75.0% and 75,0%, respectively. Conclusion: CEUS is a non-invasive, accurate method to diagnose superior mesenteric artery stenosis, which provides important reference information for clinical treatment. Key Word(s): 1.
