{Reference Type}: Journal Article {Title}: Intervention in COVID-19 linked hypercoaguable states characterized by circuit thrombosis utilizing a direct thrombin inhibitor. {Author}: Seshadri M;Ahamed J;Laurence J; {Journal}: Thromb Update {Volume}: 1 {Issue}: 0 {Year}: 2020 Dec 暂无{DOI}: 10.1016/j.tru.2020.100009 {Abstract}: •Circuit thrombosis complicates CRRT in COVID-19 despite standard heparin-based anticoagulation regimens.•5 cases of CRRT thrombosis despite heparin-based anticoagulation resolved using a direct thrombin inhibitor, argatroban.•Changes in fibrinogen levels better reflected response to anticoagulation than did changes in D-dimer levels.•High fibrinogen levels and decreased anti-thrombin III activity may relate to argatroban superiority in these cases.
