Aortoesophageal fistula: Case report and literature review

Endoscopic Diagnosis of a Clinically Silent Aortoesophageal Fistula: Case Report and Review of the Literature

We report a rare case of a secondary aortoesophageal fistula discovered incidentally during elective upper endoscopy. The patient had previously undergone repair of a descending thoracic aortic aneurysm with a Dacron interposition graft. Esophagoscopy 2 months after the aneurysm repair demonstrated a large mid-esophageal erosion with visualization of the aortic graft at the base. The aortoesophageal fistula had been clinically silent to this point. During preparation for surgery the patient developed large-volume esophageal hemorrhage and died following attempted endovascular repair of the fistula. A review of the literature on the diagnosis and surgical management of aortoesophageal fistula is presented.

Aortoesophageal fistula caused by aneurysm of the thoracic aorta: successful surgical treatment, case report, and literature review

Aortoesophageal fistula induced by atherosclerotic thoracic aortic aneurysm is rare, but is usually a fatal disorder, with few survivors reported. We report the case of a 72-year-old man with aortoesophageal fistula successfully treated in a two-stage operation. In the first stage, we performed resection and replacement of the aortic aneurysm with a prosthetic graft in situ, esophagectomy, cervical esophagostomy, and jejunostomy. After the patient recovered well postoperatively, a transmediastinal retrosternal interposition of the stomach was performed, with esophagogastroanastomosis in the cervical area, to re-establish the gastrointestinal tract. We include a discussion of the causes, diagnostic approach, management of the aorta and esophagus, and review of the literature.

Aortoesophageal fistulae due to gunshot wounds: report of two cases with one survivor

We report the cases of two patients who developed aortoesophageal fistulae after sustaining gunshot wounds to the chest. One suddenly exsanguinated 5 hours postinjury while in the angiography suite. The other manifested 4 weeks postinjury while in a rehabilitation hospital for associated spinal cord injury. The diagnosis and management were complicated, but the patient lived. He is the only survivor of aortoesophageal fistula due to gunshot wound that we could find in the literature.

Aortoesophageal fistula: a comprehensive review of the literature

Aortoesophageal fistula (AEF) is a relatively rare but life-threatening cause of upper gastro-intestinal bleeding. The clinical characteristics of AEF are so unique that a presumptive bedside diagnosis can be made at the time of presentation. In the past decade, surgical management has improved to the point that cure is now possible. For these reasons, we have reviewed the literature. We summarize our findings with respect to the etiology and clinical characteristics of AEF. Further, we discuss the diagnostic modalities that may be used to confirm the diagnosis, and the therapeutic modalities available to slow the hemorrhage, so as to allow time to correct the anatomic defect.

Aortoesophageal fistula arising as a complication of prolonged nasogastric tube placement

Aortoesophageal fistula is a rare disorder that may result from many causes. In this report, we describe the unique case of a 71-year-old woman who developed an aortoesophageal fistula following prolonged placement of a nasogastric tube. The presence of dense fibrous adhesions between the aorta and esophagus may have facilitated the development of aortoesophageal fistula in this patient.
