Dissecting aneurysm of common iliac artery in a long-distance runner

Abstract

We present an unusual case of a long-distance runner suffering from acute dissection of a common iliac artery (CIA) aneurysm with endofibrotic lesions. He suffered from acute pelvic and abdominal pain after exercise. Computed tomography angiography confirmed the dissecting aneurysm of the left CIA without signs of rupture. After cutdown, resection of the CIA and iliac bifurcation as well as bypass grafting was performed. Histologic examination confirmed endofibrotic lesions without calcifications. Complicated iliac artery aneurysm could be the result of endofibrotic lesions. Clinicians should keep this in mind, even if physical examination findings and the ankle-brachial index are normal at rest and after exercise.
