Request Case 5: Graft patency verification with flow measurement

Transit Time Flow Measurement (TTFM) to verify graft patency.
This is the third step of the surgical workflow.

REQUEST is the first multicenter study documenting the surgical changes from the combined use of Transit Time Flow Measurement (TTFM) and High Frequency Ultrasound Imaging (HFUS). The results showed that 25% of the patient population had one or more surgical procedure changes made.
