螺旋CT胸部重建与纤支镜在儿童气道畸形诊断中的应用比较

Spiral CT chest resconstruction and bronchoscopy in airway deformed children diagnosis of comparson

探讨螺旋CT胸部重建与纤支镜在儿童气道畸形诊断中的应用价值。方法对反复咳喘疑气道畸形的患儿行螺旋CT胸部重建及纤支镜检查并比较两种方法的差异。结果螺旋CT胸部重建与纤支镜均可发现气道的病变,另螺旋CT胸部重建技术还可显示气道与周围组织的关系,阻塞远端的气道情况。但对3级以下支气管管内病变准确性下降,且不能同时进行治疗。结论螺旋CT胸部重建可部分代替纤支镜检查,尤其对危重症不能耐受手术的患儿,提高了儿童气道病变的诊断水平,与纤支镜联用可更全面地诊断儿童气道病变。

Objective To approach the application value of reconstruction of the chest of spiral CT and bronchofibroscope to diagnose the airway abnormality of children. Methods We examined patients with recurrent and persistent wheezing suspected airway abnormality with reconstruction of the chest of spiral CT and bronchofibroscope, and compare their difference. Results Both reconstruction of the chest of spiral CT and branchofibroscope could found the pathological changes of airway, reconstruction of the chest of spiral CT could show the relationship of the airway and the surrounding tissue and the blockage circumstance of the distant airway. But it decreased the accurate rate to diagnose the pathological changes of airway below segmental bronchus and could not do the therapy simultaneously. Conclusions Reconstruction of the chest of spiral CT could partly replace the bronchofibroscope, especially in the grave patients could not tolerate the operation. It raised the lever of diagnosis of the pathological changes of airway in children. It can make full-scale diagnosis of the pathological changes of airway in children with the use of bronchofibroscope.
