Surveillance of infrainguinal arterial reconstructions: Importance of duplex-derived peak systolic velocity and ankle brachial index in femorodistal graft assessment

The high incidence of flow reducing graft and inflow/outflow artery lesions remains a major problem in femorodistal reconstructions. To detect these abnormalities which may threaten graft permeability, some authors [6, 15] rely upon ABI measurements alone in certain clinical situations. In contrast, other groups [2, 3, 4, 8, 11] emphasize the importance of duplex scanning and duplex-derived velocity parameters to identify the failing graft.
