Aortoesophageal Fistula after Endovascular Repair for Aberrant Right Subclavian Artery Aneurysm

Abstract

A 76-year-old woman with malignant rheumatic arthritis developed dysphagia and hoarseness secondary to an aberrant right subclavian artery aneurysm. We performed a hybrid endovascular repair with concomitant surgical treatment for the aberrant right subclavian artery aneurysm. One month after discharge, she was emergently admitted to our hospital because of chest pain and fever. We diagnosed aortoesophageal fistula and stent graft infection based on computed tomography, gallium scintigraphy, and esophagoscopy results. Esophagectomy, elimination of the infected stent graft, and muscle plombage were performed during several surgeries. However, she died of hemorrhagic shock secondary to an aortobronchial fistula.
