Multi-detector row computed tomographic evaluation of bronchopleural fistula: correlation with clinical, bronchoscopic, and surgical findings.

摘要

OBJECTIVES: To evaluate the usefulness of multi-detector row computed tomography (CT) in the diagnosis of bronchopleural fistula (BPF) and to correlate CT features with clinical, bronchoscopic, and surgical findings. METHODS: Twenty-four patients had a final diagnosis of BPF. Thin-section axial and coronal multiplanar reformation images from multi-detector row CT datasets were assessed by 2 radiologists in consensus. The CT direct sign of BPF was a fistulous tract between the bronchus or lung and pleural space. The indirect signs were air bubbles beneath the bronchial stump or suspected fistula. RESULTS: Computed tomography demonstrated fistulous tract (central type, 3; peripheral type, 11) or indirect signs of BPF (central type, 3; peripheral type, 6), whereas bronchoscopy demonstrated 2 fistula openings (all central type) and indirect signs of BPF (central type, 2; peripheral type, 1). CONCLUSIONS: Thin-section axial and multiplanar reformation images are helpful in the diagnosis of BPF. Multi-detector row CT can be an initial diagnostic modality of BPF.
