目的 探讨肝移植术后脂肪肝的超声声像图表现.方法 对437例接受原位肝移植手术,术后常规腹部超声检出脂肪肝患者的声像图表现进行分组,对均匀弥漫性脂肪肝组与非均匀性脂肪肝组患者的血流动力学异常表现进行分析.结果 超声检出肝移植术后脂肪肝36例(36/437,8.2%),其中非均匀性脂肪肝10例(10/36,27.8%),均匀弥漫性脂肪肝26例(26/36,72.2%).非均匀性脂肪肝组10例中7例发生血流动力学异常 均匀弥漫性脂肪肝组26例中仅4例发生血流动力学异常,非均匀性脂肪肝组患者血流动力学异常的发生率明显高于均匀性脂肪肝组(P〈0.05).结论 肝移植术后脂肪肝患者的超声表现以均匀弥漫性脂肪肝为主 非均匀性脂肪肝更多表现出血流动力学异常.
Objective To analyze the ultrasonic manifestation of fatty liver disease after liver transplantation. Methods A retrospective analysis was performed on 38 patients with fatty liver disease in 437 patients who accepted orthotopic liver transplant (OLT). The fatty liver diseases were divided into two groups of uniform and non-uniform fatty livers. The hemodynamic abnormalities of the patients of two groups were analyzed. Results The incidence rate of fatty liver disease after liver transplantation was 8.2% (36/437). The percentage of non-uniform fatty livers was 27.8 % (10/36) and uniform fatty livers was 72.2% (26/36). 10 cases of non-uniform fatty livers of hemodynamic abnormalities occurred in 7 cases. 36 cases of uniform fatty livers of hemodynamic abnormalities occurred in 4 cases. There was significant difference between the two groups of non-uniform and uniform fatty livers ( P 〈 0.05 ). Conclusion The major sonographic finding of fatty liver disease was uniform fatty liver. Non-uniform fatty liver showed more cases of hemodynamic abnormalities.
