[Thrombotic occlusion of an arteriovenous Cimino shunt in acute pancreatitis (author's transl)].

An arteriovenous (Cimino) shunt in both right and left forearms clotted during an episode of acute pancreatitis in two patients on chronic haemodialysis. Systemic hypercoagulability (circulating fibrin monomers, shortening of r and k time in the thrombelastogram and shortening of the PTT-time) occurred in association with inhibition of fibrinolysis (prolongation of euglobulin lysis time). Localized thrombosis at the shunt is thought to be due to superimpostition of systemic hyper-coagulability on a local increase in platelet adhesiveness.
