title: Aortoesophageal fistula and aortic pseudoaneurysm induced by swallowed fish bone: a report of two cases.
abstract: Esophageal perforation caused by accidental swallowing of fish bones can lead to rare complications, such as aortoesophageal fistula accompanied by aortic pseudoaneurysm, which can be fatal if not properly handled. We report two rare cases of aortoesophageal fistula and aortic pseudoaneurysm caused by esophagus perforation after accidental swallow of fish bone; the patients also had purulent mediastinitis and esophagitis. The treatment of aortic pseudoaneurysm was successful in both cases, with one patient undergoing surgical resection and aortic neoplasty and the other patient undergoing endovascular stent graft placement. Long-term antibiotic treatment was administered to both patients after surgery. There were no postsurgical complications, and the patients recovered without incident.
