Aortoesophageal fistula with hemorrhagic shock successfully treated with resuscitative endovascular balloon occlusion of the aorta.

BACKGROUND: Aortoesophageal fistula (AEF) is a rare cause of upper gastrointestinal hemorrhage. Despite diagnostic and therapeutic advances, the mortality rate in AEF patients remains high because of its fulminant course, even with maximal intensive care. Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a resuscitation technique to control life-threatening bleeding. It has become an important modality in the management of life-threatening, traumatic or non-traumatic, arterial bleeding. However, it's use in hemorrhagic shock caused by cancer has rarely been reported.

CASE PRESENTATION: A 51-year-old woman with a history of esophageal cancer presented to our emergency department with hematemesis. Computed tomography was performed because of a strong suspicion of hemorrhagic shock. With a diagnosis of AEF due to esophageal cancer, emergency thoracic endovascular aortic repair was performed while the bleeding was controlled using REBOA. Staged elective esophageal reconstruction was successfully performed.

CONCLUSIONS: Hemostasis is crucial in patients who present with suspected hemorrhagic shock attributable to AEF. The timely implementation of REBOA has shown promise and potential effectiveness in such cases.
