新生儿肺气漏的X线诊断分析

Radiographic diagnosis of lung frequent hemorrhoid in neonates

目的:探讨新生儿肺气漏的X线表现及其鉴别诊断。方法:对60例新生儿肺气漏的正位X线胸片进行回顾性分析,其中25例同时摄水平侧位X线胸片,4例行CT扫描。结果:X线表现气胸38例,纵隔积气18例,间质性肺气肿16例,胸壁或颈部皮下积气2例,未发现心包积气及气腹病例。其中有20例合并2种以上气漏表现;52例有吸入性肺炎;3例有湿肺,其中1例为使用呼吸机时气道压力过高所致。结论:X线摄片是诊断新生儿肺气漏的最可靠方法,CT能进一步明确肺气漏的部位、范围及程度。

Objective： To discuss the X-ray manifestation and differential diagnosis of newborns with lung frequent hemorrhoid. Methods：The supine anteroposterior chest films of 60 neonates with lung frequent hemorrhoid were retrospectively analyzed. Among them, additional supine lateral chest film with horizontal projection was performed in 25 cases and spiral CT scanning in 4 cases. Results： The X-ray demonstrated that 38 cases had pneumothorax, 18 pneumomediastinum, 16 interstitial emphysema and 2 subcutaneous gas accumulation in the chest or the neck. No pneumatosis or pneumoperitoneum were detected. Two or more frequent hemorrhoidage performances were displayed in 20 cases;aspiration pneumonia was found in 52 cases;wet-lung disease was detected in 3 cases, 1 of which was caused by high pressure of the breathing machine. Conclusions ： X-ray photograph is most reliable in diagnosis of the neonate lung frequent hemorrhoid,and CT can help to confirm the location,scope and extent of the disease.
