HAEMORRHAGIC SHOCK SECONDARY TO AORTO-ENTERIC FISTULA AFTER TREATMENT WITH BEVACIZUMAB FOR METASTATIC COLORECTAL CANCER CASE REPORT AND REVIEW OF THE LITERATURE.

We present the case of a 57-year-old woman with metastatic colorectal cancer being treated with Bevacizumab and FOLFOX, who came to the emergency department with haematemesis. Gastroscopy showed a duodenal ulcer without active bleeding. Subsequently, he suffered haemodynamic instability and an Angio-CT scan revealed an aortoenteric fistula, requiring urgent surgery. Bevacizumab can cause rare complications such as this, and early detection is crucial for effective treatment.
