Doppler Ultrasound as a Unique Diagnosis Test in Peripheral Arterial Disease.

Background: The aim of this study was to analyze duplex ultrasound (DUS) and intraoperative angiography concordance for diagnosis of lower limb peripheral artery disease and its value for surgical planning.

Materials And Methods: This was a prospective, observational study, including patients who underwent revascularization of the lower limbs during 2018, diagnosed by DUS only or combined with preoperative computed tomography (CT) angiography. The concordance between preoperative DUS or CT angiography and the intraoperative angiography was studied using the Cohen kappa coefficient (k).
