Objective We aimed to determine the incidence of and associated risk factors for endovenous heat-induced thrombosis (EHIT) after endovenous radiofrequency ablation (RFA). Methods We retrospectively reviewed the medical records of 82 patients with 97 great saphenous veins undergoing RFA from 2012 to 2014. Results The incidence of EHIT was 10.3%. Class 1, 2, and 3 EHIT was found in 50%, 30%, and 20% of legs, respectively. No class 4 EHIT, deep vein thrombosis, or pulmonary emboli occurred. Univariate analysis revealed that the associated risk factors for EHIT were a vein diameter of >10 mm, operative time of >40 min, and Caprini score of >6. Multivariate analysis revealed that the independent risk factors associated with EHIT were a vein diameter of >10 mm and operative time of >40 min. Conclusions A vein diameter of >10 mm and operative time of >40 min might be predictive factors for EHIT following RFA.

Background Venous thromboembolism is a frequent complication of COVID-19 infection. Less than 50% of pulmonary embolism (PE) is associated with the evidence of deep venous thrombosis (DVT) of the lower extremities. DVT may also occur in the venous system of the upper limbs especially if provoking conditions are present such as continuous positive airway pressure (CPAP). The aim of this study was to evaluate the incidence of UEDVT in patients affected by moderate-severe COVID-19 infection and to identify potential associated risk factors for its occurrence. Methods We performed a retrospective analysis of all patients affected by moderate-severe COVID-19 infection admitted to our unit. In accordance with the local protocol, all patients had undergone a systematic screening for the diagnosis of UEDVT, by vein compression ultrasonography (CUS). All the patients were receiving pharmacological thromboprophylaxis according to international guidelines recommendations. Univariate and multivariate analyses were used to identify risk factors associated with UEDVT. Results 257 patients were included in the study, 28 patients were affected by UEDVT with an incidence of 10.9% (95% CI, 7.1–14.7). At univariate analysis UEDVT appeared to be significantly associated (p< 0.05) with pneumonia, ARDS, PaO2/FiO2, D-dimer value higher than the age adjusted cut off value and need for CPAP ventilation. Multivariate analysis showed a significant association between UEDVT and the need for CPAP ventilation (OR 5.95; 95% IC 1.33–26.58). Increased mortality was found in patients affected by UEDVT compared to those who were not (OR 3.71; 95% CI, 1.41–9.78). Conclusions UEDVT can occur in COVID-19 patients despite adequate prophylaxis especially in patients undergoing helmet CPAP ventilation. Further studies are needed to identify the correct strategy to prevent DVT in these patients.

Abstract Background: DVT (Deep vein thrombosis) was one of the most common and sever complications after TKA (total knee arthroplasty). When tourniquet use and sometime the reuse was performed for surgery convenient of TKA. There was not sure if tourniquet use or reuse during operation would increase DVT after TKA.Methods: A retrospective study was performed about primarily TKA in our institute continuous 5 years. Univariate analysis was performed and potential intervention variables (P ≤ 0.1) were included in multiple factor analysis to certain the independent risk factors.Results: 807 patients (431 females and 376 males) were included with mean age was 65 years old. 3.84% (31 patients) were occurred sym-DVT (symptomatic DVT) one month after TKA with median time of diagnosis was 17 days. Incidence of sym-DVT after tourniquet reuse was significant high than once use and no use (7.25% versus 2.54% and 1.86%, P = 0.014 and 0.072), mean time of tourniquet use was 90.46 ± 14.28 mins in once and 106.58 ± 16.13 mins in reuse (P = 0.045). After multiple analysis, independent risk factors were revealed as history of tumor (P = 0.021), history of DVT (P < 0.001) and tourniquet reuse (P = 0.005).Conclusions: Tourniquet reuse was associated with highly incidence of sym-DVT other than history of tumor and DVT. There should be once use of tourniquet for prevent sym-DVT.

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.

Abstract Objective: The purpose of this study was to investigate the incidence of and independent risk factors for deep venous thrombosis (DVT) in the uninjured limb, before and after operation, in patients with lower extremity fractures.Methods: 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 then divided into a thrombosis group and a no thrombosis group according to the preoperative and postoperative ultrasonography results. The thrombosis group was defined as patients admitted to our hospital with DVT in the uninjured limb and the no thrombosis group was defined as patients without DVT in the uninjured limb.Results: This study enrolled 1454 patients who met the inclusion criteria. The incidence of preoperative DVT in the uninjured limb was 9.63% whereas the postoperative incidence was 20.29%. Age (OR=0.965, 95 CI%: 0.954 - 0.977; P=0.000) and gender (OR=0.667, 95% CI: 0.451-0.986, P=0.042) were independent risk factors for preoperative DVT in the uninjured limb. Blood loss (OR=0.997, 95 CI%: 0.995-1.000; P=0.020), D-dimer levels at admission (OR=0.941, 95 CI%: 0.887-0.999; P=0.045), and postoperative day 5 D-dimer levels (OR=0.889, 95 CI%: 0.819-0.965; P=0.005), were independent risk factors for postoperative DVT in the uninjured limb.Conclusion: In conclusion, the actual incidence of DVT in the uninjured lower extremity after fracture may currently be underestimated and should be pay more attention.

Abstract Objective: Clinical characteristics, anticoagulant protocols and risk factors of deep Vein thrombosis (DVT) in patients with femoral and pelvic fractures were analyzed throughout the perioperative period to provide references for early identification and optimization of risk factors.Methods: This was a retrospective study. A total of 569 patients undergoing surgery of femoral and pelvic fractures from May 2018 to December 2019 were included. The Clinical data including general conditions,trauma, surgery,anticoagulant protocols and laboratory indexes were collected.According to the results of deep vein Doppler ultrasonography of the lower extremities, the patients were divided into non-DVT group and DVT group.Univariate analysis and multivariate logistic regression analysis were used to identify the independent risk factors of preoperative and postoperative DVT.Results: The incidence of DVT was 40.25%, PE was 1.93%, and preoperative DVT was 26.71%,which was higher than the incidence of postoperative DVT of 17.22%. Most of them were thrombus on the affected side (60.26%) and distal thrombus (81.66%).The average time of DVT formation was 6.55±0.47 days after trauma and 6.67±0.48 days after surgery. Chronic obstructive pulmonary disease(COPD), anemia, hypoproteinemia, non-anticoagulation before surgery, delayed anticoagulation after trauma and admission, high energy trauma, multiple injuries, drinking history, and advanced age were independent risk factors for perioperative DVT.The increased level of fibrinogen degradation products was an independent risk factor for preoperative DVT. These risk factors were identified to be independently associated with postoperative DVT, including intraoperative blood transfusion, postoperative blood transfusion, pulmonary infection, preoperative non-anticoagulation, postoperative delayed anticoagulation, preoperative waiting time > 7d, operative time > 2h, c-reactive protein, fibrinogen level, platelet count 1 day after surgery, c-reactive protein, fibrinogen, and hemoglobin levels 3 days after surgery, comminuted fracture.Conclusions: At present, anticoagulation and other DVT prevention and treatment programs have not changed the current situation that the incidence of DVT is still high. Through the analysis of the risk factors of DVT throughout the perioperative period, optimizing the perioperative blood transfusion, preoperative lung disease, hypoproteinemia, anemia, inflammation, etc., and surgery as soon as possible after trauma may further reduce its incidence.
