    Abstract:
    BACKGROUND & OBJECTIVE: Liver transplantation is widely accepted as an effective therapy of hepatoma. Perioperative dynamic observation of coagulation function is important for graft-receivers. This study was to explore perioperative changes of coagulation functions in the local advanced liver cancer patients who received liver transplantation. METHODS: Clinical data of 31 local advanced liver cancer patients, underwent liver transplantation from Sep. 2003 to Jan. 2007, were analyzed. Platelet (PLT) counting, prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), fibrinogen (Fib) and international normalized ratio (INR) before operation, at anhepatic phase and the first week after operation were analyzed to evaluate congulation function. RESULTS: The coagulation functions of most patients were normal before operation. The six parameters varied significantly at anhepatic phase and on most days of the first week after operation when compared with the preoperative levels (P<0.05). The elevation of PT, APTT, TT and INR and the decrease of Fib and PLT were more apparent at anhepatic phase when compared with the preoperative levels [PT: (19.51+/-3.78) s vs. (14.16+/-1.46) sû APTT: (77.01+/-30.51) s vs. (40.19+/-4.11) sû TT: (27.50+/-15.10) s vs. (19.46+/-3.05) sû INR: 1.61+/-0.37 vs. 1.11+/-0.16û Fib: (1.73+/-0.70) g/L vs. (3.38+/-1.00) g/Lû PLT: (108+/-60)x10(9)/L vs. (184+/-108)x10(9)/L, all P<0.01]. In the first week after operation, the elevated PT, APTT, TT and INR levels decreased gradually, APTT was even lower than the preoperative level [(32.05+/-6.50) s vs. (40.19+/-4.11) s, P<0.01]. These changes appeared usually on 1-2 days after operation. Decreased PLT and Fib regained slowly at the first week after operation when compared with the preoperative levels [Fib: (2.13+/-0.53) g/L vs. (3.38+/-1.00) g/L, P<0.01û PLT: (145+/-90)x10(9)/L vs. 184+/-108]x10(9)/L, P<0.05], but the values were normal. According to stratification analysis, the hypocoagulability was more obvious in the patients with moderate or severe cirrhosis and those with Child-Pugh B level than in their counterparts. CONCLUSIONS: The coagulation functions of local advanced liver cancer patients shift from hypocoagulatory to hypercoagulatory or normal in perioperative period, therefore, prevention of bleeding should be focused on at anhepatic phase and on 1-2 days after operation while prevention of thrombosis should be focused on after the first week after operation. The degree of liver cirrhosis and Child-Pugh level could help to evaluate postoperative coagulation disorder.
