Concordance between preoperative ultrasound arterial mapping in the femoropopliteal and distal sector and intraoperative angiography.

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.

Preoperative mapping of the aortoiliac territory with duplex ultrasound in patients with peripheral arterial occlusive disease.

Objective: Duplex ultrasound (DUS) arterial mapping of the aortoiliac area is limited by obesity, abdominal gas, and the need to use a low-frequency probe (and therefore poorer resolution) in the examination. The aim of this study was to analyze the degree of agreement between DUS mapping of the aortoiliac area and angiography or contrast-enhanced computed tomography angiography (CTA).

Methods: This was a retrospective observational study.
