Abstract

Aims: The present study analyzes the concordance between arterial mapping of this sector using duplex ultrasound and intraoperative angiography.

Methods: A retrospective, single-center observational study was carried out. The study sample consisted of patients subjected to open or endovascular surgery of the femoropopliteal and distal sector with prior ultrasound arterial mapping from January 2017 to December 2022. Sensitivity, specificity, positive (PPV) and negative predictive values (NPV) of arterial mapping with duplex ultrasound versus intraoperative angiography were evaluated, the degree of concordance between the two techniques and the correlation between surgical planning and the surgery finally performed.

Results: 167 patients were analyzed. A total of 1837 segments were explored, of which 149 (8.1%) were not able to be evaluated. Regarding the global precision of ultrasound in predicting significant arterial lesions (stenosis > 50% or occlusion), sensitivity was 85.26% (95% confidence interval [95%CI]: 82.33-88.19%), specificity 88.57% (95%CI: 86.63-90.51%), PPV 80.41% (95%CI: 77.24-83.58%), and NPV 91.61% (95%CI: 89.89-93.34%). Global concordance assessed by the kappa index was 0.725 (95%CI: 0.691-759). The surgical indications based on arterial mapping coincided with the final surgery performed in 97.6% of the cases.

Conclusions: Arterial mapping of the femoropopliteal and distal sector with duplex ultrasound could be considered as the sole preoperative imaging technique for surgical planning.

术前股骨和远端超声动脉测绘与术中血管造影的一致性。
目的:本研究分析了使用双工超声绘制该区动脉图和术中血管造影之间的一致性:方法:进行了一项回顾性单中心观察研究。研究样本包括2017年1月至2022年12月期间接受股骨和远端开腹或血管内手术并事先进行超声动脉造影的患者。评估了双相超声动脉造影与术中血管造影的敏感性、特异性、阳性预测值(PPV)和阴性预测值(NPV),两种技术的吻合程度,以及手术计划与最终实施的手术之间的相关性:结果:分析了 167 名患者。结果:分析了 167 名患者,共探查了 1837 个节段,其中 149 个节段(8.1%)无法评估。关于超声预测重大动脉病变(狭窄>50%或闭塞)的总体精确度,敏感性为85.26%(95%置信区间[95%CI]:82.33-88.19%),特异性为88.57%(95%CI:86.63-90.51%),PPV为80.41%(95%CI:77.24-83.58%),NPV为91.61%(95%CI:89.89-93.34%)。用卡帕指数评估的总体一致性为 0.725(95%CI:0.691-759)。97.6%的病例根据动脉测绘得出的手术指征与最终实施的手术相吻合:结论:使用双工超声对股骨和远端进行动脉测绘可作为手术规划的唯一术前成像技术。
