Effects of splenectomy on blood coagulation and fibrinolysis in patients with liver cirrhosis: possible role of the spleen in haemostasis

Blood coagulation and fibrinolysis before and after splenectomy was studied in 74 cases of liver cirrhosis. A hypocoagulable state was found before splenectomy, but the platelet count, and the levels of fibrinogen, plasminogen, alpha 2-macroglobulin and antithrombin III increased significantly after splenectomy (p less than 0.05 to p less than 0.001). A marked improvement was observed on the values of r (reaction time), k (clot formation time) and ma (maximal amplitude) of thrombelastograms (p less than 0.05 to p less than 0.001). The prothrombin time was reduced after the surgery, but not significantly (p less than 0.1, greater than 0.05). The levels of alpha 1-antitrypsin remained almost unchanged, while serum fibrinogen-fibrin degradation products (FDP) showed a slight decrease postoperatively. The immunohistologic study of the spleen excised from 7 cases with liver cirrhosis, with the use of the direct immunofluorescence technique, demonstrated the deposits of fibrin in the splenic cords in all cases. It was not recognized in the spleens of 4 cases without cirrhosis used as the control. A further study of the spleen weight and plasma fibrinogen level showed that a significant inverse correlation exists between these two par...Continue Reading

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
