Twenty patients, aged 4 months to 58 years, were evaluated for liver transplantation by duplex sonography, and 15 transplantations were completed; 42 postoperative examinations were performed. Sonographic findings were correlated with seven preoperative and five postoperative angiographic evaluations. Preoperative duplex US findings included tumors, portal vein occlusion, varices, biliary obstruction, and variant vascular anatomy. Postoperative findings included hepatic artery occlusion, portal vein occlusions (one with cavernous transformation), portal vein stenosis, biliary obstruction, intrahepatic and extrahepatic fluid collections, and air in the portal vein due to ischemic bowel. Use of angiography allowed confirmation of the vascular abnormalities and demonstrated evidence of rejection in patients with normal Doppler waveforms. Duplex sonography is a valuable portable technique for evaluating these patients and can be used in triage of patients requiring angiography.
对20名年龄在4个月至58岁之间的患者进行了肝脏移植的双功超声检查评估，其中15例完成了移植手术；进行了42次术后检查。超声检查结果与7次术前和5次术后血管造影评估结果相关。术前双功超声检查结果包括肿瘤、门静脉闭塞、静脉曲张、胆道梗阻和血管解剖变异。术后检查结果包括肝动脉闭塞、门静脉闭塞（1例伴有海绵样变性）、门静脉狭窄、胆道梗阻、肝内和肝外液体积聚以及因缺血性肠病导致的门静脉内气体。血管造影的应用可证实血管异常，并在多普勒波形正常的患者中显示排斥反应的证据。双功超声检查是评估这些患者的一种有价值的便携式技术，可用于对需要血管造影的患者进行分诊。
