Livedo Reticularis and Bowel Ischemia After Carbon Dioxide Arteriography in a Patient With CREST Syndrome

Philip L Johnson et al. J Vasc Interv Radiol.

Abstract

For 30 years, CO(2) gas has been used as a safe alternative to iodinated contrast agents for angiography in patients with renal insufficiency or allergy to iodine. CO(2) angiography is well tolerated when performed properly, and serious complications are rare. However, severe complications may occur if the physical properties of CO(2) and the specific pathophysiology of an individual patient are not carefully considered. The present report describes a case in which diffuse livedo reticularis, bowel ischemia, and renal insufficiency developed following CO(2) angiography in a patient with CREST syndrome (calcinosis, Raynaud phenomenon, esophageal dysmotility, sclerodactyly, and telangiectasia).
