Electromagnetic navigational bronchoscopy-guided fiducial markers for lung stereotactic body radiation therapy: analysis of safety, feasibility, and interfraction stability.
Embolization coils as fiducial markers for pulmonary stereotactic body radiation therapy (SBRT) are perceived to be the optimal marker type, given their ability to conform and anchor within the small airways. The aim of our study was to assess retention, placement, migration, feasibility, and safety of electromagnetic navigational bronchoscopy (ENB)-guided embolization coil markers throughout courses of SBRT. ⋯ ENB placement of embolization coils as fiducials for lung SBRT image guidance is associated with a low rate of iatrogenic pneumothoraces, and resulted in reliable placement of the fiducials in close proximity to the lung nodule. Embolization coils retained their relative position to the nodule throughout the course of SBRT, and provide an excellent alternative to linear gold seeds.

Mounier-Kuhn syndrome or congenital tracheobronchomegaly is a rare clinical and radiologic condition. It is characterized by a tracheal and bronchial dilation. ⋯ The cause of this condition is not clearly understood; however, histopathologic findings of atrophy of smooth muscles and elastic tissue in the trachea and main bronchi have been observed. Tracheobronchomegaly can be associated with tracheal and bronchial diverticuli.

Inflammatory pseudotumors are rare solid, non-neoplastic masses that can mimic pulmonary malignancy. It occurs most commonly in children and young adults and is usually found incidentally. ⋯ The occurrence of this tumor exclusively in the pleura has not been described before. We present a case of inflammatory pseudotumor of the pleura and its successful management.

Case ReportsClosure of chronic bronchopleural fistula using atrial septal occluder device.
Chronic persistent bronchopleural fistulae (BPF) are challenging management problems. The management of BPF includes various surgical and medical procedures and of great value is the use of bronchoscopy and different devices. In high-risk surgical patients, bronchoscopic procedures serve as a temporary bridge until the patient's clinical condition improves, whereas in other patients bronchoscopic procedures may be the only option. We present a case of postoperative chronic BPF closed by a less invasive interventional bronchoscopic procedure using an atrial septal occluder device.

The usefulness of endobronchial ultrasonography-guided transbronchial needle aspiration at the lobar, segmental, or subsegmental bronchus smaller than a convex-type bronchoscope.
Endobronchial ultrasonography-guided transbronchial needle aspiration (EBUS-TBNA) is a standard procedure for approaching the lesion adjacent to extrapulmonary bronchus. We started to use wedge insertion of a convex endobronchial ultrasound bronchoscope into bronchi narrower than the diameter of the bronchoscope itself to perform EBUS-TBNA. Our objective was to investigate the bronchus in which EBUS-TBNA was possible and safe. ⋯ EBUS-TBNA can be performed by inserting a 6.9 mm EBUS bronchoscope into airways with a mean diameter ≥ 4.5 mm as measured on computed tomography before bronchoscopy.
