<p>We experienced a case of Tracheobronchopathia Osteochondroplastica(TO)discovered by difficult tracheal intubation during general anesthesia. A 66 year-old woman was diagnosed with acute appendicitis, and underwent emergency surgery under general anesthesia. Mask ventilation was easily performed after induction of anesthesia. Despite Cormack-Lehane grade I with direct laryngoscopy, the end-tracheal tube with an internal diameter(ID)of 7.0 mm could not pass through the glottis because of friction beneath the glottis. After confirming mask ventilation, we re-assessed the airway with computed tomography images. Several protrusions from the anterior part of the tracheal wall seemed to disrupt tracheal intubation. Finally, the trachea was successfully intubated with the thinner tube(ID 6.0 mm), rotating the bevel toward the posterior wall of the trachea after passing the glottis.</p><p>Because TO often progresses asymptomatically, patients with TO may undergo general anesthesia without a diagnosis. Although TO is one cause of difficult intubation, patients can be managed safely.</p>

<p> A 64-year-old man was scheduled for the removal of a left atrial myxoma. After tracheal intubation, we attempted to insert a pulmonary artery catheter (PAC) from the right internal jugular vein, but there was resistance after the PAC advanced 20 cm. When the PAC was pushed more strongly, the insertion successfully continued to 50 cm, but the right ventricular pressure could not be confirmed. We then pulled the PAC to remove it, but there was a strong resistance at about 40 cm. We performed chest radiography to confirm the location of the PAC, which revealed that the PAC entered from the right internal jugular vein into the right subclavian vein, thus it was bent in the axillary region, with the tip located in the superior vena cava. The PAC was subsequently pulled out of the operation field during cardiopulmonary bypass. Overall, to prevent the PAC from getting stuck, it should not be forcibly pushed during its insertion when resistance is encountered, and fluoroscopic guidance should be considered as an aid.</p>
