Value of color duplex sonography for evaluation of tibioperoneal arteries in patients with femoropopliteal obstruction: A prospective comparison with anterograde intraarterial digital subtraction angiography

摘要: Purpose: This study investigated the accuracy of color duplex sonography (CDS) compared with anterograde intraarterial digital subtraction angiography in evaluation tibioperoneal arteries patients peripheral arterial occlusive disease. Methods: Fifty consecutive femoropopliteal obstruction were examined immediately before planned percutaneous transluminal angioplasty. All CDS examinations performed by one observer; angiograms interpreted independently two readers (A1, A2). We agreement concerning judgement dominant crural artery (suitable for an eventual femorocrural bypass operation) and severity lesions. Results: Concerning artery, interobserver between was better (kappa value, 0.76) than versus A 1 (0.61) 2 (0.56). However, differences not statistically significant. The results independent (no significant kappa values) following criteria: presence diabetes; clinical stage disease; kind obstruction; status popliteal artery. lesions, values significantly higher ( p (posterior tibial, 0.87; anterior 0.79; peroneal, 0.52) A1 (0.51; 0.46; 0.07) (0.35; 0.38; −0.05). sensitivity (vs as reference) detecting a hemodynamically relevant lesion (stenosis or occlusion) 100% posterior tibial 78% 92% peroneal Conclusion: Compared angiography, value CDS—with its currently used technology—for lower leg suitable operation who have is limited. It cannot replace accurate preoperative angiogram routine practice, use should be restricted to special cases (such history severe allergic reaction contrast media severely impaired kidney function). also limited morphologic features runoff their full length
