Abnormal collateral arterial systems in Takayasuʹs arteritis and Lericheʹs syndrome evaluated by whole body acquisition using multislice computed tomography

Takayasuʹs arteritis causes various arterial changes, including wall thickening, occlusion, aneurysm, and calcification. Similarly, Lericheʹs syndrome causes occlusion of the abdominal aorta or iliac arteries accompanied by ischemic symptoms of the distal lower extremities. Both diseases are potentially associated with the development of unexpected collateral arteries throughout the body. We evaluated whole body arteries in subjects with Takayasuʹs arteritis and Lericheʹs syndrome using 16-slice multislice CT and concluded that it was a useful tool to detect unexpected collateral arterial systems in Takayasuʹs arteritis or Lericheʹs syndrome in a non-invasive fashion.
