title: [Clinical significance of preventive treatment of thrombosis for patients undergoing gynecological surgery with high risk factors].
abstract: OBJECTIVE
  To explore the clinical significance of preventive treatment of thrombosis for patients undergoing gynecological surgeries with high risk factors.
  
  
  METHODS
  Prospectively, randomized and cases controlled study was performed in 143 patients underwent gynecological surgery with high risk factors to explore the prevention effectiveness and safety in morbidity of lower extremity deep venous thrombosis (LDVT) and relative effected factors, who were enrolled to three groups according to different preventive treatment: group using intermittent pneumatic calf compression (IPC) in 47 cases, group using low-molecular-weight hepairin (LMWH) in 48 cases and control group in 48 cases with no prevention strategy.
  
  
  RESULTS
  The morbidity of LDVT on lower extremity was 6% (6/94) in group IPC and 1% (1/96) in group LMWH, 18% (17/96) in control group, which was obviously reduced in group IPC and group LMWH than that in control group (P < 0.05), while there was no significantly difference between group IPC and group LMWH (P > 0.05). After surgery in 3 or 4 days, the morbidity of LDVT in group IPC was 1/6, zero in group LMWH and 71% (12/17) in control group, there was significantly reduced in group IPC and group LMWH than that in control group (P < 0.05). There was no side-effects in group IPC, only 1 case in group LMWH presented small quantity bleed in vagina remnant, while no incision bleeding and bleed tendency. Single-variate analysis indicated that elder age, abdominal surgeries and malignant tumor were as the independent factors to effect preventive treatment of thrombosis (P < 0.05).
  
  
  CONCLUSIONS
  LDVT in patients underwent gynecological surgeries with high risk factors can be obviously reduced and delayed by preventive treatment, which is no side-effects, while be effected by the factors of elder age, abdominal surgeries and malignant tumor.
