Abstract
Background:Although cases with abdominal aortic aneurysm and common iliac arterial aneurysms are common, a case with an aneurysm conjugated with an abdominal aortic aneurysm and common iliac arterial aneurysms are not frequently reported. Case: Abdominal aortic aneurysm was diagnosed by ultrasonography in a 71-year-old woman during a medical check-up. Imaging modalities could not identify either common iliac artery. Due to the size of the aneurysm, she underwent an abdominal aortic replacement. Results: The operative findings showed that the form of the aneurysm incorporated two spheres. All of both external iliac arteries and both internal iliac arteries were arose directly from the aneurysm. Conclusion: Because a congenital absence of the common iliac artery is quite a rare abnormality, the aneurysm was thought to be formed by an abdominal aortic aneurysm and bilateral common iliac arterial aneurysms.
