摘要目的:探讨民用航空人员肝脏纤维增生性结节（hepatic fibroproliferative nodular，HFN）的超声诊断分型及航空医学鉴定。方法:回顾性分析2017年1月至2022年7月于成都民用航空医学中心行超声检查检出HFN的38例民用航空人员的临床资料。归纳实时超声检查病灶的声像图特征并分型，与患者其他影像学资料（肝脏CT或MRI）进行比较分析。结果:38例民用航空人员中男性33例，女性5例；其中28例患者完成肝脏CT或MRI至少1项检查。HFN的超声声像图表现为肝脏孤立型纤维增生性结节14例，其中12例与CT结果一致；肝脏局限型纤维增生性结节17例，其中1例与CT相符，2例与MRI相符；肝脏弥漫型纤维增生性结节2例；肝脏单纯型纤维增生5例。38例中有5例因病灶较大予以暂时不合格结论，经手术后体检合格，其余33例体检结论均为合格。结论:超声诊断能提供较为准确的HFN声像图特征，依据病灶大小、数目及形态，有助于航空医学鉴定及后续治疗。

abstractsObjective:To investigate the ultrasonic diagnosis classification of hepatic fibroproliferative nodular (HFN) and aeromedical assessment in civil aviation personnel.Methods:A retrospective analysis was carried out on the clinical data of 38 civil aviation personnel with HFN diagnosed via ultrasound in the physical examination of Civil Aviation Medicine Center Chengdu from January of 2017 to July of 2022. The sonographic features of the lesions were summarized and classified based on real-time ultrasound examination, and compared with other imaging data (CT or MRI scans of the liver) of the patients.Results:Among 38 civil aviation personnel, there were 33 males and 5 females. Out of these, 28 patients received at least one liver CT or MRI examination. The sonographic features of HFN were as follows: 14 cases of solitary fibroproliferative nodular, in which 12 cases were consistent with CT results; 17 cases of localized fibroproliferative nodular, in which 1 case was consistent with CT and 2 cases were consistent with MRI; 2 cases in diffuse fibroproliferative nodular and 5 cases of simple fibrohyperplasia in the liver. Among the 38 cases, 5 cases were temporarily grounded due to the large lesion, and qualified for flight after surgery. The remaining 33 cases were qualified for flight directly.Conclusions:Ultrasound diagnosis can provide a certain accurate sonographic features of HFN and is helpful to the aeromedical assessment and subsequent treatment based on the considerations on the size, number and shape of lesions.
