title: Analysis of deep venous thrombosis after Gynecological surgery: A clinical study of 498 cases.
abstract: OBJECTIVE
  To find out the clinical characteristics and risk factors for deep venous thrombosis (DVT) after gynecological surgery.
  
  
  METHODS
  Four hundred and ninety-eight patients treated surgically in the department of gynecology of our hospital from July 2012 to May 2014 were reviewed retrospectively. The data including patient age, gender, medical history, hospital stay, anesthesia type, operation time, occupation type, operative or postoperative medicine, perioperative bleeding, postoperative activity time, mortality rate and so on, were collected.
  
  
  RESULTS
  Among 498 patients, 58 were included in the thrombosis group, 423 patients in the non-thrombosis group and 17 patients were excluded. The incidence of deep venous thrombosis was 11.6%. In 58 cases with deep venous thrombosis, 6 cases developed pulmonary embolism and two patients died, the mortality rate for pulmonary embolism is 33.3%. In multivariate analysis, age, malignant tumor, cardiovascular comorbidity and postoperative hemostatics dose are independent risk factors, physical labour and minimally invasive surgery are protective factors for DVT.
  
  
  CONCLUSIONS
  The patients with elder age, malignant tumor, cardiovascular comorbidity or large postoperative hemostatics dose should be paid high attention to and the minimally invasive surgery are optimal treatment in preventing DVT.
