Perioperative alteration of posterior tibial artery perfusion by contrast-enhanced ultrasound in patients with peripheral artery disease after endovascular therapy.

ABSTRACT:

Background

Contrast-enhanced ultrasound (CEUS) has potential applications in both the diagnosis and perioperative quantification of distal limb microcirculation in patients with peripheral artery disease (PAD). This study aimed to evaluate the perioperative changes and potential clinical utility of the luminal perfusion parameters of the posterior tibial artery (PTA) assessed by CEUS in PAD patients who had undergone endovascular therapy (EVT).

Methods

We retrospectively reviewed the hospitalization records of PAD patients who underwent EVT, and pre- and post-EVT CEUS at a single center between January 2020 and February 2022. The perioperative CEUS perfusion parameters and peak systolic velocity (PSV) of the PTA were recorded. The CEUS perfusion parameters included peak inte
