研究目的: |
主要目的:评估下肢骨折患者中,股静脉及所有小腿深静脉(含肌间静脉)阴性时排除腘静脉血栓的诊断价值(以腘静脉血栓检出率和阴性预测值表示)。 次要目的:评估狭义小腿静脉定义下的诊断性能;分析30天内新发腘静脉血栓发生率;探讨骨折部位及术前/术后状态的影响;评估超声报告判读一致性。 |

|
Objectives of Study: |
Primary Objective: To assess the diagnostic value (detection rate and NPV) of excluding popliteal vein thrombosis based on negative findings in the femoral vein and all calf deep veins (including intermuscular veins) in patients with lower extremity fractures.Secondary Objectives: (1) To evaluate diagnostic performance using a narrow definition of calf DVT; (2) To determine 30-day incidence of new popliteal DVT; (3) To analyze effects of fracture site and preoperative/postoperative status; (4) To assess inter-reader reliability of ultrasound reports. |

Data will be extracted from the Hospital Information System (HIS) and PACS. Two researchers will independently extract and cross-check the data. A database will be built using Excel (version 16.0) with double data entry. Final analysis will use SPSS 26.0 and R 4.2. Data will be stored on an encrypted hospital server accessible only to core team members. |
