Early administration of SAV reduces the risk of complications. The presence of leucocytosis and severe coagulopathy can predict adverse outcomes.

The prevalence of CAN in diabetes mellitus is high. Higher age, longer duration of diabetes and peripheral neuropathy are significant risk factors. QTc interval in the ECG can be used to diagnose CAN with reasonable sensitivity, specificity and positive predictive value.

Dysphagia in an elderly patient necessitates urgent clinical evaluation to exclude the possibility of an underlying esophageal malignancy. Atherosclerotic aortic aneurysms are common in old age, but dysphagia aortica resulting from compression of the esophagus by an aortic aneurysm is a rare cause for dysphagia. Development of a malignant esophago-airway fistula can occur from a variety of tumors, the most common of which is esophageal cancer. A case of longstanding dysphagia resulting from dysphagia aortica later developing an esophageal malignancy complicated by esophago-bronchial fistula is outlined in this unique case report.
