Esophageal Left Subclavian Artery Fistula Caused by The Esophageal Foreign Body: A Case Report.

Left subclavian artery esophageal fistula usually occurs after esophageal cancer surgery, which is a rare complication, and it is even rarer after stent implantation of left subclavian artery pseudo-aneurysm. This paper reports the case of a 21-year-old male patient with left subclavian artery pseudo-aneurysm. Two-plus months after stent implantation, he stopped anticoagulant and antiplatelet drugs and developed pain in his left upper limb. The patient was diagnosed with arterial fistula. He was discharged from the hospital successfully after several operations, such as thoracic aortic stent implantation, left common carotid artery left axillary artery artificial vascular bypass. Conclusion: Early diagnosis and positive treatment lead to a good prognosis for patients with esophageal left subclavian artery fistula.
