Evaluation of Distal Hemodynamic Changes of Lower Extremity after Endovascular Treatment: Correlation between Measurements of Color-Coded Quantitative Digital Subtraction Angiography and Ankle-Brachial Index

TTP measurements derived from ccDSA provide an easy and objective method for assessment of distal hemodynamic changes after endovascular treatment of lower-extremity peripheral arterial disease (PAD). It may provide a quantitative method to assess the adequacy of endovascular interventions and provide more objective suggestions for procedure endpoints, with potentially better clinical outcomes for patients with PAD.
