This report describes a rare case of acute life-threatening stridor due to membranous tracheitis that occurred as a complication of endotracheal intubation, performed for video-assisted thoracotomy. An obstructive fibrin clot was found in the subglottic region by bronchofiberscopy, and removal provided complete relief of the airway obstruction. The mechanism of the development of this fibrin membrane may have interacted with local tracheal trauma from the endotracheal tube. Membranous tracheitis should be considered in the differential diagnosis of stridor and airway obstruction after endotracheal intubation because it is a life-threatening complication of this procedure.

An 80-year-old woman presented to our outpatient center with abdominal pain and blood-stained stools. She underwent a colonoscopy, which showed a 4-cm type II tumor in the rectum. About 2 h after the colonoscopy, mild facial edema and subcutaneous emphysema developed around her neck. ⋯ The air seemed to have leaked from a 2-cm inflamed diverticulum in the sigmoid colon. The mesosigmoid was also expanded by air. We discuss the anatomical mechanism of the various clinical presentations of extraluminal air following colonoscopy.

A case demonstrating a false aneurysm in the palmar segment of the ulnar artery caused by a Fogarty's catheter, which had been inserted during a thrombectomy, is described. The diagnosis was suspected based on a clinical examination, and duplex ultrasonography and computed tomography (CT) confirmed an aneurysm in the palmar segment of the ulnar artery. The patient underwent a successful aneurysmectomy with end-to-end reanastomosis.
