ABSTRACT
RATIONALE: Atrioesophageal fistula (AEF) is a rare but serious complication of atrial fibrillation (AF) catheter ablation with associated high mortality rates. PATIENT CONCERNS: A 42-year-old male patient who underwent catheter ablation in local hospital 20âdays ago because of persistent AF was admitted to our Emergency Room with unconsciousness and high axillary temperature and white blood cell count. Craniocerebral CT scan found multiple infarct lesions in both frontal and occipital lobes. Pneumatosis between the left atrium and the esophagus was observed in the chest CT. DIAGNOSES: AEF. INTERVENTIONS: We performed a salvage operation of the left atrium debridement, and left atrium patch repairing under extracorporeal circulation. We opened the mediastinum, and dissected the esophageal perforation. A special irrigating catheter with multiple side ports on the tip was placed from the esophagus to the posterior mediastinum through the esophageal orificium fistulae. We also inserted a gastrointestinal tube to the jejunum under gastroscopy. Three additional drainage tubes were inserted into the esophageal bed and the right thoracic cavity. OUTCOMES: The procedure was successful. But 7âdays later, the patient's family chose to forgo treatment due to multiple cerebral infarcts, respiratory and blood system infection, liver failure, and other complications. LESSONS: AEF is a rare but fatal complication after catheter ablation. Heightened vigilance is required for early recognition of the AEF. Surgical treatment should be performed as early as possible, especially before the neurological complications occur.

RATIONALE: Marfan syndrome (MFS), an autosomal dominant hereditary disease, often results in structural and functional abnormalities of the aortic wall. Because of residual aortic aneurysm or aortic dissection, patients with MFS usually need repeat operations after the first operation. PATIENT CONCERNS: A patient diagnosed with MFS who had undergone 2 surgeries because of abdominal aortic dissection aneurysm and Stanford A type aortic dissection at different times. DIAGNOSES: MFS. INTERVENTIONS: Due to aneurysmal dilatation of the residual descending aorta, we performed the third surgery for him through using 2 artificial stent grafts to fix and package the area of the remaining vessel in our hospital. OUTCOMES: The result was good, and the patient was discharged successfully. LESSONS: Using artificial material to repair and wrap the area of the residual vessel during the first surgery can provide an anchor area for future endovascular stent implantation and also offer a possibility for stent implantation in patients with MFS.
