Is there a possible role for haemostasis in the development of perigraft reaction complicating the modified Blalock Taussig shunt?
The perigraft reaction is an unusual complication found in patients in whom a modified Blalock Taussig shunt has been created using a polytetrafluoroethylene graft. We found that, in two infants, consistent laboratory findings during such a perigraft reaction were hypofibrinogenemia, increased levels of thrombin-antithrombin III complex, prothrombin fragment 1 and 2 and products of degradation of fibrin. Normalization of the levels of fibrinogen produced resolution of the perigraft reaction.
