To determine the signs of bronchial dehiscence on computed tomographic (CT) scans in a select subset of lung transplant recipients.
In 23 patients who underwent single or bilateral sequential lung transplantations, CT scans were obtained for suspected or known diagnosis of bronchial dehiscence. Dehiscence was identified at bronchoscopy in 17 of the 23 patients. In four patients, the dehiscence was bilateral, resulting in 21 anastomotic dehiscences.
CT allowed identification of a bronchial defect in 100% of the bronchoscopically proved dehiscences but only one (5%) of the 18 bronchoscopically proved intact anastomoses. CT also demonstrated extraluminal air in 100% of the bronchoscopically proved dehiscences. Only a very small amount of extraluminal air (without associated bronchial defect) was identified on CT scans in the early postoperative period in four additional patients with bronchoscopically proved intact anastomoses.
CT is an easily performed and well-tolerated technique that has a high degree of sensitivity and specificity for depicting bronchial dehiscence.
确定特定肺移植受者亚组中计算机断层扫描（CT）上支气管裂开的征象。
对23例行单肺或双侧序贯肺移植的患者进行CT扫描，以怀疑或确诊支气管裂开。23例患者中有17例在支气管镜检查时发现裂开。4例患者为双侧裂开，共21处吻合口裂开。
CT对支气管镜证实的所有裂开均能显示支气管缺损，而对支气管镜证实吻合口完整的18例患者中仅1例（5%）显示缺损。CT还在支气管镜证实的所有裂开中100%显示管腔外气体。另外4例支气管镜证实吻合口完整的患者在术后早期CT扫描中仅发现极少量管腔外气体（无相关支气管缺损）。
CT是一种易于实施且耐受性良好的技术，对显示支气管裂开具有高度的敏感性和特异性。
