Outcome Measures

Primary Outcomes (1)

  • the percentage of different symptoms of thromboembolic disease(%)

    different patients will have various symptoms of embolism like dyspnea, chest pain, hemoptysis and syncope. And we plan to describe the distribution of it.

    10 months after the operation

Secondary Outcomes (2)

  • the location of embolism

    10 months after the operation

  • the risk factors of thromboembolic disease

    10 months after the operation

Study Arms (1)

Thromboembolic Disease

the patients who undergo gynecological operations but develop thromboembolic disease

Eligibility Criteria

Age20 Years - 80 Years
Sexfemale
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

The planned sample size was based on data from a previous study, in which the standard deviation was 5. We assumed an one-tailed α error of 0.05 and a sampling error of 1.0. we propose to enroll 60 participants and allow for a dropout rate of 10% for an effective sample size of 54.

You may qualify if:

  • Volunteer to participate in the study with informed consent;
  • Females aged 20-80 who are confirmed with some gynecological diseases and are treated with surgery but embolism happens unfortunately.

You may not qualify if:

  • Pregnancy, lactation, postmenopause, or planned pregnancy within two years;
  • Patients with blood diseases prone to thrombosis and those with a history of thrombus were excluded;
  • History of hyperparathyroidism, infectious diseases (tuberculosis, AIDS), autoimmune diseases, or digestive system diseases (malabsorption, crohn disease and dysentery);
  • Other diseases or heavy injuries that will interfere with the results;
  • Simultaneous participation in another clinical study with investigational medicinal product(s) or researcher thinks the subjects are not suitable for this trial.
