“…There are several case reports and case series of percutaneous coronary stent insertion and of cardiac surgery in patients with haemophilia A [8][9][10][11][12][13][14] and haemophilia B [11,[15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30]. Some of the older reports describe perioperative haemostatic strategies that are now outdated, such as plasmapheresis with fresh frozen plasma replacement [17] and reliance on prothrombin complex concentrate [16,18,21]. A few authors employed CIs of plasma-derived FIX replacement [24,29,30] and of factor VIII replacement [11][12][13] for cardiac surgery, but in the English literature, only one used rFIX [26] and that was by bolus dosing.…”
