ABSTRACT
OBJECTIVE:
We sought to use a novel technique to measure the functional hemodynamics of peripheral arterial lesions during endovascular interventions.BACKGROUND:
Functional hemodynamics has not been thoroughly evaluated during endovascular interventions. The aim of our study is to evaluate the feasibility and the potential benefits of pedal pressures measurements from tibio-pedal access.METHODS:
We retrospectively reviewed 100 consecutive patients who underwent endovascular interventions via tibio-pedal artery access between October 3, 2018 and December 15, 2018. Baseline and postintervention pedal pressures from the pedal sheaths were measured. We also evaluated the pedal-brachial index (PBI) which is defined as the pedal sheath pressure divided by the simultaneously brachial cuff pressure. We compared baseline pedal pressures, postintervention pedal pressures, baseline PBI, postintervention PBI, % change of PBI ([postintervention PBI minus baseline PBI]/baseline PBI), and resting ankle-brachial index (ABI) versus baseline PBI in this cohort of patients.RESULTS:
All 100 patients had successful tibio-pedal artery access. Baseline pedal pressure was 70 + 30 mmHg with post intervention pedal pressure of 133 + 27 mmHg (p < .001). Baseline PBI was 0.75 + 0.24 with post intervention PBI of 1.09 + 0.19 (p < .001). The correlation coefficient of resting ABI vs. baseline PBI was 0.55. The % change of PBI was 63.2 + 52.4%. There was significant improvement of postintervention PBI when compared to baseline PBI in the majority of patients.CONCLUSIONS:
Obtaining pedal pressures and PBI from tibio-pedal access can be a feasible tool for endovascular interventions. This simple technique can provide us important functional hemodynamics information before and after peripheral revascularization.Palavras-chave
