Summary
A rare case of aortoenteric fistula in a nonaneurysmal aorta is presented, linked to cancer treatments like bevacizumab. This highlights the need for vascular imaging in oncology patients with gastrointestinal bleeding.
Area of Science:
- Vascular Surgery
- Oncology
- Gastroenterology
Background:
- Aortoenteric fistula is typically linked to aortic aneurysms or grafts.
- Modern cancer therapies, including antiangiogenic drugs, can cause aortic injury in nonaneurysmal vessels.
- Fallopian tube carcinoma treatment involving pelvic radiation and bevacizumab is a risk factor.
