Abstract:
PURPOSE: We performed this study to assess the suitability of conventional angiography (CA) vs. multi-detector row helical CT angiogram (MD-CTA) as a method of preoperative diagnostic imaging for low extremity arterial surgery. METHODS: From February 2004 to September 2006, 23 patients (4 claudicants, 19 limb-threatening ischemia) were studied with CA and MD-CTA preoperatively. The site and degree of stenotic or occlusive lesions in arterial segments from the renal artery to the dorsalis pedis artery were compared with both methods. We also compared the surgical inflow and outflow site changes in preoperative planning based on CA and MD-CTA and the final outcome. Additional diagnostic value and test-related complications were also analyzed. RESULTS: The median age of patients was 68 years old (range: 43~89 years), with a male to female ratio of 1.3:1. Twenty-three patients had CA after an MD-CTA scan. One hundred fifty lesions were detected in these patients. The total ratio of consistency for occlusion in CA vs. MD-CTA was 69.6%. Three patients received amputation treatment and eleven patients received a bypass operation. The agreement between the preoperative plan based on MD-CTA and the final operation was 100%, even in critical limb ischemia. There were no serious complications related to the tests. CONCLUSION: These findings suggest that MD-CTA is an adequate preoperative imaging study of infrainguinal arterial surgery and may be substituted for conventional angiography without any serious complications.
