  • Title: Fibrinolytic activity in plasma and deep vein thrombosis after major abdominal surgery.
    Author: Mellbring G, Dahlgren S, Reiz S, Wiman B.
    Journal: Thromb Res; 1983 Dec 15; 32(6):575-84. PubMed ID: 6229899.
    Abstract:
    In a prospective study of the frequency of deep vein thrombosis (DVT) in 45 patients subjected to major abdominal surgery, 17 patients showed signs of DVT as assessed by the 125I-fibrinogen test. In 15 of the patients the DVT was diagnosed during the first four postoperative days. Blood samples were taken pre- and postoperatively and analysed for fibrinogen, prothrombin complex, APTT, platelet-count, plasminogen, alpha 2-antiplasmin, fibrin(ogen) degradation products, and plasmin-alpha 2-antiplasmin complex (PAP). The latter was used in order to reflect the fibrinolytic activity. Preoperatively, and postoperatively on day 3, the levels of PAP were significantly higher in patients without postoperative DVT. The data suggests that patients subjected to major abdominal surgery, who have enhanced fibrinolytic activity preoperatively, have a lesser tendency to develop postoperative DVT. Patients with postoperative DVT may have decreased fibrinolytic ability. From the data of the other parameters it is concluded that patients with DVT can have increased levels of FDP at the time of development of thrombosis.
