Intraoperative Duplex Ultrasound Criteria for Performing Interposition Bypass in the Treatment of Popliteal Artery Entrapment Syndrome

IDUS was very helpful in the operative management and intraoperative decision making process for popliteal artery entrapment. An elevated PSV of 250-275 cm/sec or greater on IDUS and a VR of 2.0 or greater, in conjunction with B-mode demonstration of arterial wall injury, was useful in identifying severely injured popliteal arterial segments. Additional prospective studies are warranted to further investigate objective criteria that indicate the need for bypass.
