Abstract:
Objective To investigate the incidence and risk factors of deep venous thrombosis in patients with open fracture of lower extremities.Methods A retrospective study was conducted to analyze the clinical data of 203 patients with open fracture of lower limbs admitted to Department of Orthopaedics and Trauma,Xi'an Jiangtong University Medical College Red Cross Hospital from January 2015 to November 2017.There were 75 males and 45 females,the average age was 47.3 years,and the age ranged from 18 to 63 years.Classification of open fracture sites of lower limbs:open fracture of femoral shaft in 59 cases;open fracture of tibia and fibula in 107 cases;open fracture of ankle in 37 cases.Gustilo classification of open fracture included 34 cases of type Ⅰ,71 cases of type Ⅱ and 98 cases of type Ⅲ.According to whether thrombosis occurs or not,the patients were divided into thrombosis group (n =63) and non-thrombosis group(n =140).The incidence of thrombosis was expressed as percentage (％).The age,fracture degree,injury type,Gustilo classification of open fracture,gender,body mass index (BMI),combined medical diseases,fracture site,preoperative and postoperative D-dimers were subjected to x2 test or Fisher's exact test.The test αt value was taken as 0.05 on both sides.P ＜ 0.05 suggested that the difference was statistically significant.Results The incidence of deep venous thrombosis in 63 cases of open fracture was 31.03％,of 63 DVT patients,5 were central thrombosis (7.93％),17 were mixed thrombosis (26.98％) and 41 were peripheral thrombosis (65.08％).The main type of thrombosis was peripheral thrombosis.There were significant differences in age,fracture degree,injury type and open fracture Gustilo type between the two groups of thrombus group and non thrombus group (P ＜ 0.05).Sex,BMI,internal medical diseases,fracture sites,and D-two polymer before and after operation were not statistically significant (P ＞0.05).Conclusions The incidence of DVT was higher in patients with open fracture of lower extremities,the main type of thrombosis was peripheral thrombosis.Age over 60 years old,high falling injury,2 or more fractures and comminuted fractures,open fractures Gustilo type Ⅲ was associated with DVT.
