Did you know?
Transit-Time Flow Measurement (TTFM) is an intra-operative tool to assess the patency and the quality of a graft in order to prevent errors from going unnoticed. TTFM relies on specific flow parameters, namely mean graft flow (MGF), pulsatility index (PI), diastolic filling (DF) and backflow (BF).
