Summary: Background: The femoropopliteal artery (FPA) plays a central role in diagnosing and treating peripheral arterial disease (PAD). FPA lesions are the most frequent cause of intermittent claudication, no other lower extremities is recanalised more frequently. Generally, ultrasound primary imaging tool PAD, particularly FPA. With development high-frame-rate technology addition to traditional modes, vector flow (VFI) has provided deeper haemodynamic insights when used carotid artery. Here, we report use VFI at level routine PAD examinations. Patients methods: In this single-centre prospective study, evaluated consecutive patients with using B-mode imaging, colour Doppler, pulsed wave Doppler (PW) flow. Hemodynamic parameters predefined locations were compared. Results: Qualitatively adequate all sites was possible 76% PAD. decreasing volume from common internal femoral via superficial popliteal artery, correlation between VFI- PW-derived-volume high every site. Based on different techniques, VFI-derived values significantly than PW-derived values. mean wall shear stress sites, whereas oscillatory index site higher that rather location. Conclusions: Our findings suggest data acquisition feasible Therefore, knowledge method its limitations, provides information beyond techniques promising new for analysis
