目的探讨超声造影在肝移植术后脾动脉窃血综合征中的诊断价值.方法应用彩色多普勒超声对311例肝移植患者术后常规进行肝实质及管道结构检查.对显示微弱或无明确肝动脉血流信号的移植肝进行超声造影,了解肝动脉增强情况,同时运用彩色多普勒检测脾动脉血流动力学.结果 7例移植肝肝动脉血流信号微弱、2例未显示肝动脉；超声造影此9例移植肝肝门处均能较清晰显示肝动脉的内径、走行,但灌注微弱.彩色多普勒显示脾动脉内径明显增粗、血流信号丰富,超声造影考虑肝移植术后脾动脉窃血.经腹腔干插管造影证实超声造影所见.结论超声造影对肝移植术后脾动脉窃血综合征具有一定的诊断价值.

Objective To investigate the utilization of contrast-enhanced ultrasound (CEUS) for the detection of splenic artery steal syndrome (SASS) after orthotropic liver transplantation (OLT).Methods Color Doppler flow imaging (CDFI) were performed at various time points post-operatively.CEUS and celiac angiography were conducted in patients suspected of SASS.Results 9 patients were suspected of SASS by slim or undetectable hepatic arterial Doppler blood signals by CDFI at various time points postoperatively.CEUS in 9 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 9 diagnoses of SASS were proven by celiac angiography.Conclusions 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.
