Pulmonary artery (PA) rupture caused by a PA Swan-Ganz catheter is a rare complication but remains fatal in almost 50% of cases. False aneurysm of the PA is a rare presentation of PA rupture and should be considered as a possible diagnosis in a patient with a new lung mass after PA catheterization. We present a case of sudden-onset pulmonary alveolar hemorrhage during cardiovascular surgery due to a traumatic PA false aneurysm. The Swan-Ganz catheter might have been displaced by the thoracic aortic aneurysm with displacement of the catheter causing the false aneurysm and bleeding.

Endoscopic submucosal dissection (ESD) is the standard treatment method for esophageal, gastric, and colorectal cancers. However, it has not been standardized for duodenal lesions because of its high complication rates. Recently, minimally invasive and simple methods such as cold snare polypectomy and underwater endoscopic mucosal resection have been utilized more for superficial nonampullary duodenal epithelial tumors (SNADETs). Although the rate of complications associated with duodenal ESD has been gradually decreasing because of technical advancements, performing ESD for all SNADETs is unnecessary. As such, the appropriate treatment plan for SNADETs should be chosen according to the lesion type, patient condition, and endoscopist’s skill.
