COVID-19 and aortoenteric fistula.

The novel coronavirus disease 2019 (COVID-19) has generated a worldwide sanitary emergency, forcing the worldwide scientific community to recommend low-evidence-based therapies. These drugs may have been involved with unsuspected side effects. We describe a case of a Primary Aortoenteric Fistula (PAEF) in a patient with a recent history of severe COVID-19, and we hypothesize whether this rare condition may have been triggered by the virus or by the drugs used against it.
