肺部超声在先天性肺囊腺瘤样病变中的应用价值分析

目的探讨肺部超声在先天性肺囊腺瘤样病变(CCAM)随访中的应用。方法收集26例CCAM,于生后1、2、3个月为患儿提供三次免费的肺部超声检查,并结合胸部X线、CT检查结果进行分析。结果肺部超声检查共检出4例肿块持续存在,均表现为胸膜下的、体积较大的肺内囊性包块,并经CT或X线检查证实肿块存在。其余22例肺部超声未及明显肿块回声,产前病变位于胸膜下或肺组织深部,肿块体积普遍偏小,12例又进行了CT或X线检查,结果提示8例肿块清晰存在;4例肿块未及明显显示,其中1例在随访过程中于3个月时肺部超声检出肺实变,病变位于近胸膜下,并经X线胸片证实为肺炎。结论肺部超声简便可行,在CCAM肿块的检出方面具有一定的限制,但在CCAM患儿的随访中具有较好的应用前景,可用于观察疾病的预后及转归。

Application of Lung Ultrasound Examination in Congenital Cystic Adenomatoid Malformation

Objective To investigate the application of lung ultrasound examination in the follow-up of congenital cystic adenomatoid malformation(CCAM).Methods Twenty-six patients with CCAM were enrolled,and three free pulmonary ultrasound examinations were performed on the neonatal at 1 month,2 months,and 3 months after birth.The results were compared with chest X-ray or CT findings.Results 4 cases were found to be persistent,all of which showed a subpleural,larger intrapulmonary cystic mass,then confirmed by CT or X-ray examination.The remaining22 cases of lung ultrasound examination did not have obvious mass echoes.The prenatal lesions were located in the subpleural or deep lung tissue.The volume of the mass was generally small.Among of these,12 cases underwent CT or X-ray examinations.The results showed that 8 cases were present clearly,and 4 cases of tumors were not shown clearly,of which 1 case was detected by lung ultrasound at 3 months during the follow-up,and the lesion was located near the pleura and X-ray tablet was confirmed to be pneumonia.Conclusions Lung ultrasound examination is simple and feasible.Though there are some limitations in mass detection,it has a good application prospect in the follow-up of neonatal with CCAM,and can observe the prognosis and outcome of the disease.
