Case ReportsObstructive fibrinous tracheal pseudomembrane.
Obstructive fibrinous tracheal pseudomembrane (OFTP) is a relatively rare cause of failed extubation. OFTP may be more common than described in the literature. OFTP results from ischemic injury to tracheal mucosa and may be the initial stage of the development of tracheal stenosis. ⋯ The patient was seen the second time in the emergency room and was treated for asthma exacerbation on the same day. Because of persistent symptoms after 3 days, CT scan of the chest was performed, which indicated necrotizing tracheitis with gas formation within the tracheal wall. Bronchoscopy showed no evidence of necrosis, but there was a thick white plaque toughly adherent to the tracheal wall.

Case ReportsExtracorporeal membrane oxygenation to support whole-lung lavage in pulmonary alveolar proteinosis: salvage of the drowned lungs.
Pulmonary alveolar proteinosis is a rare lung disease characterized by accumulation of lipoproteinaceous material within the alveoli. Therapeutic whole-lung lavage (WLL) under general anesthesia is the standard treatment in patients with progressive symptomatic disease. ⋯ Rarely, hyperbaric chamber or extracorporeal membrane oxygenation (ECMO) has been utilized to perform WLL to manage severe hypoxemia, with venovenous ECMO being used more often. We present a case of hypoxemic and hypercarbic respiratory failure from pulmonary alveolar proteinosis successfully managed by placing the patient on venoarterial ECMO to facilitate the performance of bilateral WLL.

Case ReportsEndobronchial ultrasound diagnosis of pulmonary embolism.
A 68-year-old woman presented for mediastinal lymph node sampling while undergoing work up for a solitary pulmonary nodule. During endobronchial ultrasound examination of the airways, an echogenic abnormality was noted within the right pulmonary artery. The patient underwent computed tomography angiography of the chest, and diagnosis of pulmonary embolism was confirmed. We describe endobronchial ultrasound evaluation of a pulmonary embolus.

Safety of ultrasound-guided small-bore chest tube insertion in patients on clopidogrel.
The safety of small-bore chest tubes insertion with ultrasound (US) guidance has been well demonstrated in patients not receiving antiplatelet therapy. Given the current widespread use of these agents, pulmonologists frequently encounter patients on this therapy and requiring drainage of the pleural space. The use of these agents clearly increases the risk of bleeding, but it is not always possible to stop this therapy before the procedure, especially in patients requiring urgent drainage and those with coronary stents. The purpose of this study is to report our experience on the safety of US-guided small-bore chest tube placement in patients receiving clopidogrel. ⋯ OH 44195: The insertion of small-bore chest tube in patients receiving clopidogrel can be safe if performed by experienced operators and by using US guidance along with lateral insertion site, which has the lowest risk of lacerating the intercostal arteries.

Temporary use of silicone stents for severe airway stenosis in untreated malignant lymphoma.
Airway stenting has become a popular method for palliation of airway stenosis; however, little has been reported about their use for patients with malignant lymphoma that occasionally causes a life-threatening condition. The aim of the study was to evaluate the efficacy and safety of airway stenting in chemoradiotherapy naive patients with severe airway stenosis due to malignant lymphoma. ⋯ Airway stenting using silicone stents is safe and effective in palliation of airway stenosis in patients with untreated malignant lymphoma, and permits postprocedural tumor-specific therapy. The response to tumor-specific therapy can be expected, and so removable stents should be selected.
