Replacement therapy for coronary artery bypass surgery in patients with hemophilia A and B

Abstract

There are only a few cases of patients with hemophilia A and B who have undergone coronary artery bypass surgery. High levels of replacement therapy with factor concentrate either with bolus or continuous infusion are usually required pre-operatively and during the first post-operative days in order to maintain the coagulation deficient factor levels greater than 80% of normal. Heparinization during cardiopulmonary bypass appears to be safe and intra-operative blood salvage using cell saver techniques reduce the need for transfusions.
