Treatment-Related Aortoenteric Fistula in a Patient With Intra-abdominal Cancer

The authors investigate the occurrence of treatment-related aortoenteric fistula in a patient with fallopian tube carcinoma, highlighting the potential role of bevacizumab in compromising vascular integrity despite the absence of an aortic aneurysm. They emphasize the importance of considering aortoenteric fistula in oncology patients presenting with gastrointestinal bleeding, particularly those who have undergone recent antiangiogenic therapy, and recommend early vascular imaging in such cases. This report contributes to the understanding of vascular complications arising from modern oncologic treatments.
