It can be difficult to localize or even lateralize the site of persistent bronchopleural fistula in patients who have undergone thoracotomy. If the site of persistent air leak can be identified noninvasively, it may be possible to repair the leak with thoracoscopic techniques and thereby avoid repeat thoracotomy. This article reports experience using 99mTc-DTPA ventilation scintigraphy to localize persistent bronchopleural fistulas in six patients. The site of bronchopleural fistula was identified in four patients. In the other two patients, no leak was identified, and the clinical course confirmed that a significant bronchopleural fistula did not exist.
对于接受过开胸手术的患者，确定持续性支气管胸膜瘘的部位甚至区分其位于哪一侧可能都很困难。如果能够通过非侵入性方法确定持续性漏气的部位，那么或许可以采用胸腔镜技术修复漏气，从而避免再次开胸手术。本文报告了使用99mTc - DTPA通气闪烁扫描法对6例患者的持续性支气管胸膜瘘进行定位的经验。4例患者确定了支气管胸膜瘘的部位。另外2例患者未发现漏气，临床病程证实不存在明显的支气管胸膜瘘。
