Planificación preoperatoria con ecodoppler en la revascularización de miembros inferiores

Abstract

IntroductionThe objective of this study is to evaluate the validity of the doppler arterial mapping compared to angiography for the detection of significant lesions, and preoperative planning in patients with peripheral artery disease (PAD). Materials and methodsCross-validation study of diagnostic test, including consecutive patients with PAD who were treated in our institution. Baseline clinical variables and risk factors were recorded. The ilio-femoro-popliteal axis were analyzed, assessing the ultrasound parameters of the lesion (stenosis <50%, 50-69%, ≥ 70%, or occlusion) and the proposed surgical planning (endovascular, open surgery, or combined surgery) compared with angiographic findings without evaluating the distal vessels. ResultsA total of 145 lower limbs of 143 patients were included from January 2012 to December 2013. Kappa agreement in the detection of significant stenosis and occlusions was increased to 0.85 in the iliac sector, 1.0 in the femoral sector, and 0.98 in the popliteal sector. The closeness of agreement between the kappa procedure based on mapping and that finally performed was 0.75. ConclusionsOur experience shows that the arterial mapping with doppler color ultrasound is valid for preoperative planning in patients with PAD, showing a greater degree of consistency in the femoro-popliteal segment.
