V.K Shankar, FRCS(Ed), S Ray Chaudhury, S FRCS(Eng), M.C Uthappa, FRCS(Glas), FRCR, A Handa, FRCS(Eng), FRCS(Ed), L.J Hands, MS, FRCS(Eng)  Journal of Vascular Surgery  Volume 39, Issue 5, Pages (May 2004) DOI: /j.jvs

2 Fig 1 Thromboelastography values (mean) for blood samples obtained during transfemoral angiography. R, Reaction time (time to initial fibrin formation); K, dynamics of clot formation; Angle, acceleration of fibrin buildup and cross-linking (clot strengthening); MA, maximum amplitude (ultimate clot strength); CI, coagulation index (overall coagulation status); ABPI, ankle-brachial pressure index; TFA, transfemoral angiography. Journal of Vascular Surgery  , DOI: ( /j.jvs )

3 Fig 2 Coagulation state of each blood sample. R, Reaction time (time to initial fibrin formation); K, dynamics of clot formation; Angle, acceleration of fibrin buildup and cross-linking (clot strengthening); MA, maximum amplitude (ultimate clot strength); CI, coagulation index (overall coagulation status); LY30, percent lysis at 30 minutes after MA; LY60, percent lysis at 60 minutes after MA; G, clot firmness as shear elastic modulus; EPL, estimated percent lysis; A, current amplitude. Journal of Vascular Surgery  , DOI: ( /j.jvs )
