Abstract：Objective To explore the occurrence of deep venous thrombosis (DVT) after femoral neck fracture and analyze its influencing factors. Methods Totally 120 patients with femoral neck fractures admitted to our hospital from January 2018 to September 2019 were selected and divided into the DVT group and the non-DVT group. Age, sex, Body Mass Index (BMI), smoking history, hemoglobin a1c, total cholesterol, triglyceride(TG) as well as fracture lateral position, ASA classification, anesthesia method, operation time, operation method and intraoperative blood transfusion volume were compared between two groups. The influencing factors of deep vein thrombosis after femoral neck fracture were analyzed with multivariate logistic regression. Results The incidence of DVT in patients with smoking history, with Hip arthroplasty, triglyceride>1.7mmol/L, glycosylated hemoglobin >6%, body mass index>25 kg/m2, with intravenous inhalation anesthesia were significantly higher, and the difference was statistically significant (χ2=4.144, 3.902, 4.257, 4.123,4.018, 3.902, all P＜0.05). Multivariate Logistic regression analysis showed that high body mass index, smoking history, high Hemoglobin a1c, high triglycerides and hip-joint replacement surgery were the risk factors of DVT incidence (OR=5.037, 7.935, 4.999, 3.976, 5.098, all P＜0.05). ConclusionThe incidence of DVT after femoral neck fracture was high, and body mass index, smoking history, high Hemoglobin a1c, high triglycerides and hipjoint replacement surgery were the risk factors of DVT incidence. Preventive intervention should be strengthened in patients with high risk factors.
