title: Interpretation of intraoperative arterial duplex ultrasound testing.
abstract: Intraoperative assessment of arterial repairs can be performed using angiography or ultrasound techniques. Duplex ultrasound is an accurate technique to image and assess the hemodynamics of repaired arteries using color and pulsed Doppler velocity spectra recordings. Procedure-specific interpretation criteria should be used to determine the technical adequacy of carotid artery endarterectomy, renal/visceral arterial repairs, and infrainguinal limb arterial bypass. The interpretation pathway for intraoperative assessment is detailed, focusing on transducer selection, imaging technique, and velocity spectra criteria for residual stenosis.
