Objective: The objective of this work is to discuss and analyze the related factors of lower extremity fracture complicated by preoperative deep vein thrombosis (DVT). Methods: A total of 11,891 patients with closed fractures of lower extremities were selected. By analyzing each patient’s gender, age, presence or absence of diabetes and hypertension, preoperative plasma D-dimer level, and color Doppler ultrasound of the lower extremity vein, the pertinent factors of the patients with lower extremity fractures complicated by preoperative DVT were analyzed. Results: A total of 578 with preoperative DVT were detected, displaying a total incidence of 4.86%. All patients were categorized into either the DVT group or non-DVT group. The results demonstrate that there were statistically significant differences between the 2 groups in age, the presence of diabetes and hypertension, the fracture site, and the preoperative plasma D-dimer level ( P < 0.05). Logistic multivariate analysis revealed that age, the presence of diabetes, and the preoperative plasma D-dimer level of patients were independent risk factors for lower extremity fracture complicated by DVT. Conclusion: Age, the presence of diabetes, the fracture site, and increased D-dimer levels were found to be potential risk factors and indicators for preoperative DVT in patients with lower extremity fractures. In addition, the preoperative plasma D-dimer level has certain guiding significance for the prediction of venous thrombosis after lower extremity fracture, which is conducive to the early prediction and diagnosis of DVT, but it often must be followed with good clinic acumen and examinations.

Abstract Background:The objective of this work is to discuss and analyze the related factors of lower extremity fracture complicated by deep vein thrombosis (DVT), and to help surgeons aptly prevent it.Methods:A retrospective analysis was conducted on the orthopedic inpatient records of the Affiliated Hospital of Shandong University of Traditional Chinese Medicine from July 2014 to November 2018, and 11,891 patients with closed fractures of lower extremities were selected.By analyzing each patient's gender, age, presence or absence of diabetes and hypertension,preoperative plasma D-dimer level, and color Doppler ultrasound of the lower extremity vein, the pertinent factors of the patients with lower extremity fractures complicated by DVT were analyzed.Results: A total of 11,891 patients were selected, including 4462 with cases of peri-hip fractures, 754with cases of femoral shaft fractures, 1776 with cases of peri-knee fractures, 1961 with cases of tibiofibular fractures, and 2938 with cases of ankle fractures.Of these patients, 643 with DVT were detected, displaying a total incidence of 5.4%.All patients were categorized into either the DVT group or non-DVT group.The results demonstrate that there were statistically significant differences between the two groups in age, the presence of diabetes and hypertension, the fracture site, and the preoperative plasma D-dimer level (p<0.05), but there was no statistically significant difference in sex (p>0.05). Logistic multivariate analysis revealed that age, the presence of diabetes, and the preoperative plasma D-dimer level of patients were independent risk factors for lower extremity fracture complicated by DVT.Conclusion: Age, the presence of diabetes and hypertension, the fracture site, and the preoperative plasma D-dimer level were found to be correlated with the incidence of DVT. Moreover,age, the presence of diabetes, the preoperative fracture site, and the plasma D-dimer level were found to be independent risk factors.

Objective. This study is aimed at investigating the incidence of deep vein thrombosis (DVT) in the uninjured limb during hospitalization and 1 month after surgery in patients with lower extremity fractures. Methods. We collected the clinical data of patients with lower extremity fractures in Xi’an Honghui Hospital. Doppler ultrasonography was used to diagnose DVT. According to the results of ultrasonography, the patients were divided into two groups: uninjured limb with DVT group and uninjured limb without DVT group. Results. A total of 494 patients who met all inclusion criteria were included in this study. The incidence rate of DVT in the uninjured limb was 19.84% and 18.83% during hospitalization and 1 month after surgery, respectively. Age (OR=1.035, 95% CI: 1.013–1.059; P=0.002) and D-dimer level 1 day after surgery (OR=1.065, 95% CI: 1.030–1.102; P<0.001) were independent risk factors for DVT during hospitalization. Similarly, age (OR=1.045, 95% CI: 1.021–1.070; P<0.001) and D-dimer level 1 day after surgery (OR=1.048, 95% CI: 1.014–1.083; P=0.006) were independent risk factors for DVT 1 month after surgery. During hospitalization and 1 month after surgery, 15.79% and 12.35% of patients had double lower limb thrombosis and 4.04% and 6.48% of patients had DVT in the uninjured limb only, respectively. Conclusion. The actual incidence of DVT in the uninjured limb in patients with lower extremity fractures cannot be ignored despite the use of anticoagulants for prevention or treatment during hospitalization. We should also be aware of DVT in the uninjured limb while focusing on DVT in the injured limb.

The purpose of this study was to identify patients at higher risk of deep venous thrombosis (DVT) in the uninjured lower extremity both preoperatively and postoperatively in patients with lower extremity fractures. We collected the clinical data of patients with lower extremities fractures who presented at Xi’an Honghui Hospital between 1 July, 2015 and 31 October, 2017. Doppler ultrasonography was used to diagnose the DVT. Patients were examined pre- and postoperatively. The patients were divided into thrombosis group and no thrombosis group according to the preoperative and postoperative ultrasonography results. The thrombosis group was defined as patients with DVT in the uninjured lower extremity and the no thrombosis group was defined as patients without DVT in the uninjured lower extremity. This study enrolled 1454 patients who met the inclusion criteria. The incidence of preoperative DVT in the uninjured lower extremity was 9.63% whereas the postoperative incidence was 20.29%. Age (OR = 0.965, 95 CI%: 0.954-0.977; P ≤ 0.001) and female (OR = 0.667, 95% CI: 0.451-0.986, P = 0.042) were independent risk factors for preoperative DVT in the uninjured lower extremity. Blood loss (OR = 0.997, 95 CI%: 0.995-1.000; P = 0.020), D-dimer level at admission (OR = 0.941, 95 CI%: 0.887-0.999; P = 0.045), and postoperative day 5 D-dimer level (OR = 0.889, 95 CI%: 0.819-0.965; P = 0.005), were independent risk factors for postoperative DVT in the uninjured lower extremity. For the patients with lower extremity fractures, age and female were associated with the preoperative DVT in the uninjured lower extremity. Blood loss, D-dimer at admission and postoperative day 5 D-dimer were associated with the postoperative DVT in the uninjured lower extremity.

To investigate the incidence and location of deep vein thrombosis (DVT) in patients with lower extremity fractures receiving pharmacological thromboprophylaxis with LMWH followed by rivaroxaban. All patients aged ≥18 years with lower extremity fractures were included in the study. Duplex ultrasonography (DUS) was performed in the lower extremities before and after surgery for DVT evaluation. According to the location, the DVT was divided into proximal, distal, and mixed thromboses. According to fracture location, patients were classified as having fractures proximal, around, and distal to the knee. All patients received sequential chemical prophylaxis. A total of 404 patients with a mean age of 44.2 ± 13.8 years were included. The incidence of DVT postoperatively was higher than that preoperatively and at 1 month postoperatively. Patients with fractures proximal and around the knee had higher DVT incidences detected on DUS postoperatively and at 1 month postoperatively. Most DVTs were located in the distal vein. DVT incidence and severity were the highest immediately after surgery. DVT incidence in fractures around and proximal to the knee increased after surgery and at 1 month postoperatively. Although with chemical thromboprophylaxis, distal DVT was the most variable during the early stage.

Abstract Background: Recent observations suggest that upper extremity deep vein thrombosis (DVT) has become more common over the last few decades. However the prevalence of this disorder within the community has not been established. The purpose of this study was to compare the occurrence rate, risk factor profile, management strategies, and hospital outcomes in patients with upper versus lower extremity DVT in a cohort of all Worcester residents diagnosed with venous thromboembolism (VTE) in 1999. Methods: The medical records of all residents from the Worcester, MA statistical metropolitan area (2000 census=478,000) diagnosed with ICD-9 codes consistent with possible DVT and/or pulmonary embolism at all 11 Worcester hospitals during the years 1999, 2001, and 2003 are being reviewed by trained data abstractors. Validation of each case of VTE is performed using prespecified criteria. Results: A total of 483 cases have been validated as acute DVT events - this represents all cases of DVT occurring in residents of the Worcester SMSA in 1999. For purposes of this analysis we have excluded 4 patients with both upper and lower extremity DVT. Upper extremity DVT was diagnosed in 68 (14.2%) of patients versus 411 (85.8%) cases of lower extremity DVT. Patients with upper extremity DVT were younger, more likely to be Hispanic, more likely to have renal disease and more likely to have had a recent central venous catheter, infection, surgery, ICU stay, or chemotherapy than patients with lower extremity DVT. They were less likely to have had a prior DVT or to have developed their current DVT as an outpatient. Although less likely to be treated with heparin, LMWH, or warfarin they were more likely to suffer major bleeding complications. Recurrence rates of VTE during hospitalization were very low in both groups. Conclusions: Patients with upper extremity DVT comprise a small but clinically important proportion of all patients with DVT in the community setting. Their risk profiles differs from patients with lower extremity DVT suggesting strategies for DVT prophylaxis and treatment for this group may need to be tailored.

Background: The aim of the study was to evaluate the frequency of recurrence and the risk factors for recurrence in patients who were diagnosed with venous thromboembolism. Methods: Between January 2005 and January 2015, a total of 412 venous thromboembolism patients (164 males, 248 females; mean age: 53.5±16.6 years; range: 19 to 95 years) were retrospectively analyzed. The demographics, underlying risk factors, comorbidities, imaging findings, and treatment data of the patients were recorded. Results: At least one transient/permanent risk factor was found in 341 (82.7%) of the index events, and the other 71 (17.2%) were idiopathic. Recurrence developed in 76 (18.4%) of the patients. The duration of the treatment in the first event was significantly longer in recurrent cases (p=0.007). The recurrence rate in patients diagnosed with only deep vein thrombosis or patients diagnosed with pulmonary thromboembolism + deep vein thrombosis was significantly higher than the patients diagnosed with only pulmonary thromboembolism (24% vs. 14.2%, respectively; p=0.007). The rate of idiopathic venous thromboembolism was higher in recurrent cases than in non-recurrent cases (26.3% vs. 15.2%, respectively; p=0.028). At the end of the first year, the mean D-dimer levels were higher in recurrent cases (p=0.034). Hereditary risk factors were also higher in recurrent cases (39.5% vs. 19.3%, respectively; p=0.031). There was no significant correlation between recurrence and mortality. Conclusion: The presence of deep vein thrombosis, idiopathic events, high D-dimer levels at the end of the first year and hereditary risk factors seem to be associated with recurrence.
