Case report: right subclavian artery pseudoaneurysm due to perforation of esophageal cancer.
A 51-year-old man presented with massive hematemesis. Perforation of upper esophageal cancer, which had already occurred at least six days earlier, progressed to upper mediastinitis. The mediastinitis contiguous to the right subclavian artery was considered to have caused a pseudoaneurysm. Rupture of the pseudoaneurysm into the esophagus resulted in massive hematemesis. Both enhanced computed tomography and angiography were diagnostic for the pseudoaneurysm. Transluminal endovascular stent-grafts placement was successful in preventing subsequent hemorrhage.
