Virtual bronchoscopy software is now available to district general hospitals (DGHs). There is limited information on the clinical utility of virtual bronchoscopy and whether it offers any additional information over conventional axial computed tomography in the setting of a busy DGH chest unit.
Virtual bronchoscopy and computed tomography findings were compared in all patients who had a virtual bronchoscopy study over a 12 month period.
Eighteen consecutive patients had virtual bronchoscopy for a specific clinical indication over the study period. Additional information was conveyed by virtual bronchoscopy in five patients (in four patients the airways distal to an obstruction were better visualised thereby influencing decisions about airway stenting and in one patient the virtual bronchoscopy study showed an endobronchial lesion missed on computed tomography). In nine patients who were unfit for fibreoptic bronchoscopy (FOB) the radiologist was more confident in excluding an obstructive airway lesion. The main indication for performing a virtual bronchoscopy study was to rule out an obstructive airway lesion in patients who were unfit for FOB (n = 11).
Virtual bronchoscopy is feasible and useful in the management of a few selected patients in a DGH chest unit. Virtual bronchoscopy may convey additional information over computed tomography when the distal airways need to be visualised and for discrete endoluminal lesions.
虚拟支气管镜软件现已应用于地区综合医院(DGHs)。关于虚拟支气管镜的临床实用性以及在繁忙的DGH胸部科室中,它相对于传统轴向计算机断层扫描是否能提供更多信息,目前信息有限。
对在12个月期间接受虚拟支气管镜检查的所有患者的虚拟支气管镜检查和计算机断层扫描结果进行比较。
在研究期间,连续18例患者因特定临床指征接受了虚拟支气管镜检查。虚拟支气管镜检查为5例患者提供了额外信息(4例患者中,阻塞远端气道的可视化效果更好,从而影响了气道支架置入的决策;1例患者中,虚拟支气管镜检查发现了计算机断层扫描漏诊的支气管内病变)。在9例不适合进行纤维支气管镜检查(FOB)的患者中,放射科医生对排除阻塞性气道病变更有信心。进行虚拟支气管镜检查的主要指征是排除不适合FOB的患者的阻塞性气道病变(n = 11)。
虚拟支气管镜在DGH胸部科室的少数特定患者管理中是可行且有用的。当需要可视化远端气道以及处理离散的腔内病变时,虚拟支气管镜可能比计算机断层扫描提供更多信息。
