RationaleBevacizumab (Bev) is a humanized monoclonal antibody that targets vascular endothelial growth factor A and is primarily used for the treatment of various solid tumors. Aortic dissection (AD) is a severe vascular disease caused by the tearing of the intimal layer of the aorta or bleeding within the aortic wall, resulting in the separation of different layers of the aortic wall. However, the pathogenesis is not fully understood. Some studies have suggested that Bev treatment is associated with the occurrence of AD.Patient ConcernsA 67-year-old Chinese male was diagnosed with rectal cancer accompanied by liver and lung metastasis. Three days after starting combined chemotherapy with Bev, the patient developed persistent abdominal pain. Abdominal CT scan revealed celiac trunk AD in the abdominal aorta.DiagnosesThe patient was diagnosed with rectal cancer accompanied by liver and lung metastases. Abdominal CT tomography revealed a celiac trunk AD.InterventionsSomatostatin combined with valsartan was used to control blood pressure. The patient was subsequently referred for vascular surgery and underwent an abdominal aortic angiography. Conservative treatment was continued.OutcomesThree months after the initiation of treatment, follow-up abdominal CT scans showed stability in the condition of celiac trunk AD, with no abdominal pain or hypertension. There were no signs of worsening dissection, aneurysm formation, or inadequate perfusion of end organs.LessonsThere may be a connection between Bev and elevated blood pressure as well as celiac trunk AD.Copyright © 2024 the Author(s).
