To assess the usefulness of standard and thin-section computed tomography (CT) in the examination of patients with possible bronchopleural fistulas (BPFs).
Twenty patients with known or suspected BPFs underwent CT. Twelve had pleural air and fluid collections; eight had air leaks. Fourteen patients also underwent thin-section CT.
The BPF or its probable cause was visualized in all patients with air and fluid collections and in two of the patients with air leaks. BPFs due to bronchiectasis, necrotizing pneumonia, or alveolar cell carcinoma were identified in 10 patients. In four others, bronchiectasis was seen but the actual communication was not. In seven patients with postoperative air leaks, standard or thin-section CT demonstrated the air-leak source in only one. Thin-section CT was superior to standard CT in six of eight patients in whom the BPF or its probable cause was visible.
Standard and thin-section CT are useful in the diagnosis and management of peripheral BPFs.
评估标准层厚及薄层计算机断层扫描（CT）在检查可能存在支气管胸膜瘘（BPF）患者中的作用。
20例已知或疑似BPF的患者接受了CT检查。其中12例有胸腔积气和积液；8例有气胸漏气。14例患者还接受了薄层CT检查。
在所有有胸腔积气和积液的患者以及2例有气胸漏气的患者中均可见BPF或其可能的病因。10例患者被诊断为支气管扩张、坏死性肺炎或肺泡细胞癌导致的BPF。另外4例可见支气管扩张，但未发现实际的瘘口。在7例术后气胸漏气患者中，标准层厚或薄层CT仅在1例中显示了漏气来源。在8例可见BPF或其可能病因的患者中，6例患者薄层CT优于标准层厚CT。
标准层厚及薄层CT对周围型BPF的诊断和治疗有帮助。
