Abstract:
Objective To investigate the incidence and risk factors of deep venous thrombosis (DVT) of lower extremity in patients with pelvic or acetabular fracture.Methods From August 2015 to December 2016,110 patients with pelvic or acetabular fracture were treated in our hospital.They were 76 males and 34 females with a mean age of 44.2 years (range,from 16 to 76 years).There were 48 pelvic fractures,including 12 anterior and posterior compression,16 lateral compression and 20 vertical shear ones by the Young-Burgess classification;there were 62 acetabular fractures,including 26 simple and 36 complex ones by the Letournel-Judet classification.The incidence of lower extremity DVT was detected preoperatively and postoperatively using ultrasound detection.The factors associated with the incidence of DVT were analyzed statistically.The risk factors were screened by single factor logistic regression analysis;the major independe risk factors were determined by multi-factor logistic regression analysis.P ＜ 0.05 was considered as statistically significant.Results DVT occurred in 32 patients (29.09％),including 21 cases (19.09％) of proximal thrombosis and 3 cases of combined pulmonary embolism.The incidence of DVT in patients with acetabular fracture was significantly higher than in those with pelvic fracture (P ＜ 0.05);the incidence of proximal DVT in patients with complex acetabular fracture was significantly higher than in those with simple acetabular fracture (P ＜ 0.05).Multivariate analysis showed that age of ＞ 60 years,combined injuries and interval of ＞ 2 weeks from injury to surgery were independent risk factors for incidence of DVT (P ＜ 0.05).Conclusions The risk of lower extremity DVT is high in patients with pelvic or acetabular fracture in spite of active prophylaxis,especially the risk of proximal thrombosis.Age of ＞ 60 years,combined injuries and interval of ＞ 2 weeks from injury to surgery may be the independent risk factors for incidence of DVT.
