Study of deep venous thrombosis in lower extremities after femoral neck fracture / 国际外科学杂志

ABSTRACT

Objective To explore the causes of deep venous thrombosis of the lower extremities after femoral neck fracture.Methods To retrospectively analyze the clinical data of 483 cases of femoral neck fractures treated from September 2014 to December 2017 from Department of Traumatic Orthopedics,Xi'an Jiaotong University School of Medicine Affiliated Honghui Hospital.Please record the patient's complications,blood transfusion volume,reduction method,internal fixation,operative time,intraoperative blood loss,and postoperative thrombosis.Count data were expressed as percentage (％) and analyzed by x2 test between the two groups;measurement data were expressed as ((x) ± s),and two independent samples was used by t test.To calculate the incidence of postoperative deep venous thrombosis in patients with femoral neck fractures and to investigate the causes of deep vein thrombosis of the lower extremities after femoral neck fractures.Results Of the 483 patients,149 cases of deep vein thrombosis of the lower extremities occurred after surgery,with an incidence of 30.8％.The reduction method,internal fixation,and intraoperative blood loss all affected the occurrence of deep venous thrombosis after femoral neck fracture (P ＜ 0.05).Among the reset methods,367 cases were open and closed,33.2％ (122/367) had deep venous thrombosis,closed reduction was 116 cases,and 23.3％ (27/116) had deep venous thrombosis.The incidence of open reduction deep venous thrombosiswas higher than closed reduction;among the internal fixation methods,fixation,the incidence of deep venous thrombosis after total hip arthroplasty and intramedullary nailing was the highest,which was 52.8％ and 50.0％,respectively.The hemorrhage volume in the thrombosis group (246.9 ± 178.1) ml was higher than that in the non-thrombosis group(206.3 ± 126.7) ml.Conclusions The incidence of deep venous thrombosis after femoral neck fractures is high,and the way of reduction,internal fixation,bedtime before operation,and blood loss during operation can affect the occurrence of deep venous thrombosis after femoral neck fracture.There are many factors affecting deep venous thrombosis after femoral neck fracture.It is necessary to fully evaluate the risk of deep venous thrombosis after operation.
