Prospective Validation of Clinical Prediction Model for Venous Thromboembolism Following Neurosurgery

Prospective Validation of Clinical Prediction Model for Venous Thromboembolism Following Neurosurgery

Validation of Clinical Prediction Model for Venous Thromboembolism Following Neurosurgery: A Multicenter, Prospective, and Cohort Study

A clinical prediction model for VTE after neurosurgical procedures during hospitalization has been developed and internally retrospectively validated. A multicenter, prospective cohort study is planned to validate this clinical prediction model again.

Inclusion Criteria:

1. age >18 years
2. underwent neurosurgical procedures during hospitalization
3. underwent preoperative ultrasound examination

Exclusion Criteria:

1. a patient with obvious bacterial or viral infection within the past two weeks before admission
2. a patient with venous thromboembolism within the past three months before surgery
3. a patient with anticoagulant therapy (direct oral anticoagulants, low molecular weight heparin) was administered continuously or intermittently before admission
4. a patient with a prior coagulation dysfunction
