“…8,[11][12][13] In this study, we introduce several new tibial parameters, including PAV, AAV, MTV, and API, which may further improve tibial artery DUS interpretation and ultimately guide revascularization approaches. PAV and AAV were first introduced by work not yet published by Brown et al 14 These parameters are helpful in consolidating the large amount of data obtained by arterial DUS mapping, and we show that they are highly specific for PAD. We believe the API is particularly valuable in assessing patients with PAD and that the two components of the calculation, AAV and PSV of the proximal profunda, serve as a surrogate assessment of in-line flow to the ankle.…”
