About
Activated clotting time (ACT) is currently recommended to monitor high concentrations heparin anticoagulation. ACT-LR was specifically designed to measure the activity of low dose of heparin used during endovascular surgery. The correlation between ACT-LR and Anti Xa activity which is considered as the gold standard seems to be debated.
Few studies in literature had shown controversial results. These studies were conducted in patients who underwent open as endovascular surgery. However, the ACT monitoring is not recommended in open surgery. In addition, heparin administration protocols are not described and specific to each centre.
In this study investigators want to study the correlation between LR-ACT and anti Xa after introducing a heparin protocol during complex endovascular procedures.
