Abstract:
Objective: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.
