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.

| Clinical Prediction Model for Venous Thromboembolism Following Neurosurgery | Diagnostic Test | This is a clinical prediction model that uses perioperative clinical indicators and laboratory tests to predict the occurrence of VTE after neurosurgery. |
| Measure | Description | Time Frame |
|---|---|---|
| Symptomatic or asymptomatic VTE | A combination of symptomatic or asymptomatic DVT and symptomatic or asymptomatic PE | 2023.3-2023.7 |
| Measure | Description | Time Frame |
|---|---|---|
| DVT | A blood clot within a deep vein, typically in the thigh or leg, which is detected with compressible ultrasound, venography, impedence plethysmography, radiofibrinogen uptake scanning or autopsy based on the time of study. This outcome combines proximal or distal DVT of the leg, upper limb DVT | 2023.3-2023.7 |

Biospecimen refers to biological specimens obtained from patients, such as blood, for routine laboratory tests and analyses, including measurement of coagulation indices, before and after surgery.
| PE |
Obstruction of a pulmonary artery or one of its branches that is usually produced by a blood clot which has originated in a vein of the leg or pelvis and traveled to the lungs, which is diagnosed by CT pulmonary angiography, ventilation-perfusion lung scanning pulmonary angiogram, or by autopsy or equivalent technology based on the time of study. This outcome combines saddle, lobar, segmental or subsegmental PE according to the anatomic location |
| 2023.3-2023.7 |
| Proximal DVT | Proximal DVT is a blood clot that is located in the popliteal, femoral, or iliac veins, which is detected with compressible ultrasound, venography, impedence plethysmography, radiofibrinogen uptake scanning or autopsy based on the time of study | 2023.3-2023.7 |
