Diagnostic Value Of Flexible Bronchoscopy And MSCT For Congenital Dysplasia Of Respiratory System In Infants

PART ONE: DIAGNOSTIC VALUE OF FLEXIBLEBRONCHOSCOPY FOR CONGENITAL DYSPLASIA OFRESPIRATORY SYSTEM IN INFANTSObjective: To investigate diagnostic value of flexible bronchoscopyfor congenital dysplasia of respiratory system in infants.Methods: Clinical data, flexible bronchoscopy and CT conclusions of173patients with congenital dysplasia of respiratory system from November1,2011to October31,2012were analyzed.Result: Classify night of congenital dysplasia of respiratory systemwas diagnosed in173patients, as tracheobronchial stenosis,tracheobronchomalacia, abnormal bronchial origin, laryngeal cartilagedysplasia, cardiovascular oppression, tracheoesophageal fistula, agenesis oflung,tracheal diverticulum and segmental bronchi absence. The rightbronchial tube was more than the left in the173patients of congenitaldysplasia of respiratory system,58.8%(160/272cases). The right upper lobebronchial tube was the highest than others,45.2%(123/272cases). CT initially prompted the tracheobronchial stenosis accounted for42.7%(41/96cases).66cases were found to have congenital heart disease in173cases.Conclusion:(1)The right bronchial tube was the predilection site of congenitalrespiratory dysplasia, specifically right upper lobe bronchus.(2) The most common classify of congenital dysplasia of respiratorysystem was tracheobronchial stenosis, tracheobronchomalacia andabnormal bronchial origin in infants.(3) The diagnostic value of flexible bronchoscopy was higher thanMSCT for tracheobronchomalacia and abnormal bronchial origin.(4)The congenital respiratory dysplasia was often associated withcardiovascular malformations. PART TWO: COMPARE THE DIAGNOSTIC VALUE OFFLEXIBLE BRONCHOSCOPY AND MSCT FORCONGENITAL DYSPLASIA OF RESPIRATORY SYSTEMIN INFANTSObjective: To investigate diagnostic value of flexible bronchoscopyand MSCT for congenital dysplasia of respiratory system in infants.Explore the diagnostic advantage of different types of respiratory dysplasiawith the flexible bronchoscopy and MSCT. Aimed to choice a reasonableexamination methods, early diagnosis provides a clinical basis.Methods: Clinical data, flexible bronchoscopy and multislice spiralCT conclusions of319patients with congenital dysplasia of respiratorysystem from November1,2011to October31,2012were analyzed.Result:476cases of Congenital dysplasia of respiratory system wasdiagnosed in319patients, flexible bronchoscopy confirmed173patients(235cases), MSCT confirmed197patients (241cases), divided into primaryand external pressure.392cases of primary dysplasia of respiratory system,flexible bronchoscopy diagnosed57.4%.360cases of lobe bronchus andabove airway dysplasia, flexible bronchoscopy diagnosed61.7%. All of76cases of tracheobronchomalacia were diagnosed by flexible bronchoscopy.All of17cases of lung tissue dysplasia were diagnosed by MSCT.84casesof external pressure dysplasia of respiratory system, the main cause of cardiovascular dysplasia, esophageal lesions, pleural lesions. Thecardiovascular dysplasia was the most common. MSCT diagnosed74casesof84cases, and flexible bronchoscopy diagnosed10cases.Conclusion:(1)Flexible bronchoscopy was easier discovery the primary dysplasiaof respiratory system than MSCT, especially lobe bronchus and aboveairway dysplasia.(2)Flexible bronchoscopy had confirmed the value fortracheobronchomalacia.(3)MSCT had higher diagnostic value for lung tissue dysplasia thanflexible bronchoscopy.(4) MSCT has the important value for the diagnosis of externalpressure dysplasia of respiratory system in infants.
