摘要目的：探讨气道黏膜隆起病变在白光支气管镜下表现及超声影像特征，探索气道内超声检查对气道黏膜隆起病变的诊断价值。方法采用前瞻性研究方法，对2013年10月至2014年11月于我院行支气管镜检查发现气道黏膜隆起的30例患者行气道内超声检查。根据支气管内超声检查结果分为血管畸形组、黏膜增厚组和黏膜囊肿组。分别记录入选病例资料：支气管镜下征象（黏膜隆起位置、形状、色泽、搏动性、黏膜表面扩张）及支气管内超声图像特点等，对结果进行分析、总结。结果30例患者共发现43例次气道黏膜隆起，符合血管特征的病变21例次，黏膜增厚19例次，黏膜下囊肿3例次。在气道黏膜隆起形态方面，束带状、扁平状以及半圆形隆起在3组均存在。结节状隆起1例次，表面毛细血管扩张1例次，隆起外观可见搏动性2例次，均为血管组。结论黏膜下血管病变是气道黏膜隆起病变的常见原因，对其活检需谨慎。白光支气管镜检查对黏膜隆起性质的诊断价值有限，气道内超声检查对黏膜隆起的诊断意义较大。

abstractsObjective To explore the white light bronchoscopic signs and ultrasound features of respiratory mucosal protrusions and to investigate the practical application value of endobronchial ultrasound . Methods This study was a prospective observation .Endobronchial ultrasound was performed in 30 patients with respiratory mucosal protrusions , which were discovered by white light bronchoscopic examination in the Second Affiliated Hospital of Fujian Medical University on October 2013 to November 2014.The 43 lesions found in 30 patients were grouped into submucosal vascular lesions , mucosal thickening , and submucosal cysts based on the result of EBUS .Following white light bronchoscopy , signs such as respiratory mucosal protrusion location, shape, color and lustre, mucosal surface expansion and ultrasonic bronchoscopic image were recorded .We analyzed the results to explore the bronchoscopic signs and ultrasound features of different respiratory mucosal protrusions .Results Of the 43 respiratory mucosal protrusions by endobronchial ultrasound examination , 21 were submucosal vascular lesions ,19 showed mucosal thickening , and 3 were submucosal cysts .Morphologically , zoster protrusions , flat protrusions and semicircle protrusions were found in the submucosal vessel group , mucosal thickening group and cyst group .One nodular protrusion , 1 surface capillary expansion , and 2 mucosal surface pulsations were found in cases with submucosal vascular lesions . Conclusions Submucosal vascular lesions were common causes of respiratory mucosal protrusions , for which biopsy should be cautious .White light bronchoscopy has limited value for diagnosing respiratory mucosal protrusions , while endobronchial ultrasound could be an important diagnostic tool for these lesions .
