In-vivo hemodynamic assessment after above-knee femoropopliteal bypass using the DynafloTM prosthesis

Aim: An ePTFE prosthesis (DynafloTM) was developed to improve the clinical outcome after above-knee femoropopliteal bypass. The prosthesis aims to reduce intimal hyperplasia (IH). The hemodynamic effect of this prosthesis has been investigated in vitro while only little in-vivo data is available. Methods: In a prospective study, 30 DynafloTM prostheses were implanted in 29 patients. 27 of the bypasses are still patent. The patients are currently undergoing investigation of hemodynamics in a two years period using color duplex ultrasound (CDUS) and ultrasound after contrast medium (USCM) administration (SonoVue).…
