The incidence of a tracheal bronchus supplying the right upper lobe has been reported to be in the range of 0.1 to 3%. We encountered 3 cases with the anomaly among 200 cases of lung surgery conducted over a year at our hospital. In the first case, we had difficulty in intubating the patient with a double-lumen tube. In the other two cases, the tracheal bronchus was detected by fiberoptic bronchoscopy during the lung surgery. Patients with a tracheal bronchus may be difficult or impossible to ventilate, especially when requiring unilateral lung ventilation. Therefore, the airway must be assessed carefully by fiberoptic bronchoscopy prior to unilateral lung surgery, keeping in mind the possibility of a tracheal bronchus, in order to design a safe way to secure it safely during the surgery.
据报道，供应右上叶的气管支气管发生率在0.1%至3%之间。在我院一年间进行的200例肺部手术中，我们遇到了3例这种异常情况。在第一例中，我们在为患者插入双腔管时遇到了困难。在另外两例中，气管支气管是在肺部手术期间通过纤维支气管镜检查发现的。患有气管支气管的患者可能难以或无法通气，尤其是在需要单侧肺通气时。因此，在进行单侧肺手术前，必须通过纤维支气管镜仔细评估气道，同时要考虑到气管支气管的可能性，以便设计出一种在手术期间安全确保气道安全的方法。
