Objective: To identify the risk factors of deep vein thrombosis (DVT) of lower limb in patients undergoing lumbar fusion surgeries, to provide a better understanding of DVT and take prophylactic measures. Methods: This study was carried out in our hospital between January 2016 and February 2020, patients undergoing lumbar fusion surgeries were included and divided into DVT group and non-DVT group, and the medical data including basic demographics, clinical characteristics, operative data, and routine biochemical parameters were collected and analyzed. Results: In the current study, 390 cases were included, 48 cases were enrolled in DVT group and 342 in non-DVT group. The incidence of DVT was 12.3%. There were significant differences in age, hyperlipemia, hypertension, occupation type, D-dimer level, hospital stay, and postoperative exercises (p<0.05), but no significant differences in gender, smoking status, drinking status, coronary heart disease, diabetes mellitus, fused segments, and operation time (p>0.05) between the two groups. In multivariate analysis, age>50 years, hypertension, D-dimer>500ug/L were independent risk factors, while postoperative exercises were protective factor for DVT. Conclusion: Those patients undergoing lumbar fusion surgeries should take more prophylactic measures including postoperative exercises if they were elderly, or hypertensive, or have high D-dimer level, in order to decrease the incidence of DVT. doi: https://doi.org/10.12669/pjms.37.1.3041 How to cite this:Li Q, Yu Z, Chen X, Zhang W.

Limb Deep Vein Thrombosis

Lower limb deep vein thrombosis (DVT) is not an uncommon postoperative complication of spinal fusion surgery. However, the related risk factors identified in previous studies remain controversial. This study aimed to investigate risk factors for lower limb DVT in patients with single-level lumbar fusion surgery. Between January 2010 and December 2016, a total of 710 patients undergoing lumbar fusion were recruited for this study, including 172 males and 538 females (aged 18-75 years). Deep vein thrombosis was detected by ultrasonography. Accordingly, patients were divided into the DVT group and the non-DVT group and compared in terms of operative data, underlying diseases, and biochemical data. Additionally, logistic regression analysis was performed to identify risk factors for lower limb DVT. The incidence of lower limb DVT was 11.8% (84 of 710 cases). Five patients were symptomatic, with lower limb pain and swelling. Two patients developed pulmonary embolism and 1 died. Binary logistic regression indicated that advanced age ( P = .001, odds ratio [OR] = 2.86, 95% CI: 1.85-5.12), hypertension ( P = .006, OR = 4.10, 95% CI: 1.09-2.30), and increased d-dimer ( P < .001, OR = 3.49, 95% CI: 2.05-6.36) were risk factors for postoperative DVT. In conclusion, for patients with single-level lumbar fusion, advanced age, increased d-dimer, and hypertension may contribute to DVT development after spinal fusion surgery. Therefore, patients with these risk factors should be protected during the perioperative period.

Abstract BackgroundVenous thromboembolism often develops after surgery and childbirth, resulting in death in some cases. Although early deep vein thrombosis (DVT) detection can predict pulmonary thromboembolism, there is no early screening method for DVT in pregnant women. Lack of consensus regarding significance or setting and cut-off value interpretation of D-dimer levels further impedes venous thromboembolism screening in pregnant women.This study aimed to examine the utility of third-trimester serum D-dimer levels for screening test for DVT during pregnancy.to determine the frequency of asymptomatic DVT using lower-limb compression ultrasonography.MethodsThis single-center retrospective study included 497 pregnant women who underwent elective cesarean section at term in our hospital between January 2013 and December 2019. Serum D-dimer levels were preoperatively measured at 32–37 gestation weeks. The presence or absence of DVT in patients with serum D-dimer levels ≥ 3.0 µg/ml, the cut-off value, was examined using compression ultrasonography. In all patients, the presence or absence of clinical venous thrombosis (symptoms such as lower-limb pain, swelling, and heat sensation) was examined within 4 postoperative weeks.The Royal College of Obstetricians and Gynecologists Guideline 2015 was referred to determine risk factors for the onset of venous thrombosis during pregnancy. Among those, we examined the risk factors for DVT that result in high D-dimer levels during pregnancy.ResultsThe median age and body mass index were 35 (20–47) years and 21.2 (16.4–41.1) kg/m2, respectively. Further, the median gestational age and D-dimer levels were 37 weeks and 2.1 (0.2–16.0) µg/ml, respectively. Compression ultrasonography was performed on 135 (26.5%) patients with a D-dimer level ≥3.0 µg/ml, with none of the patients showing DVT. All patients were followed up for 4 postoperative weeks, with none presenting with venous thromboembolism. Multivariate analysis showed that hypertensive disorders of pregnancy is an independent risk factor for venous thromboembolism that causes high D-dimer levels (odds ratio: 2.48, 95% confidence interval: 1.05–6.50, P=0.04).ConclusionThere may be low utility in screening for DVT using D-dimer levels in the third trimester. Further, prepartum asymptomatic DVT has a low frequency, indicating the low utility of compression ultrasonography.Trial registrationInstitutional Review Board of Tottori University Hospital (IRB no. 20A149).

Only few studies are available on the comparison of the efficacy and safety of the acenocoumarol and warfarin. The authors treated patients with deep vein thrombosis according to latest recommendations using D-dimer measurements and duplex ultrasound exams. Aims: To examine the efficacy and safety of the two anticoagulants in patients with lower limb deep vein thrombosis. Methods: The authors included 100 consecutive patients with lower limb dee deep vein thrombosis. The patients were treated with acenocoumarol or warfarin in doses to achieve INR values between 2 and 3.5 for six months. After 6 months the authors performed physical examination, D-dimer measurements and ultrasound exams, and determined the rate of unchanged thrombotic process, as well as the rate of complete and incomplete recanalisations. Results: There was no significant difference in the number of INR determinations during treatment between the two groups (acenocoumarol group 442, warfarin group 416). The INR values were in the therapeutic range in 71.2% and 75.4% of patients in the acenocoumarol and warfarin groups, respectively. Dose adjustment was necessary in 129 and 84 times in the acenocoumarol and warfarin groups, respectively (p = 0.0025). The therapy was optimally effective (INR value was within the therapeutic range throughout the treatment period) in 46% and 52% of patients in the acenocoumarol and warfarin groups, respectively. The thrombotic vein was completely recanalised in 91.9% of patients treated optimally, and only 80.4% of patients treated not optimally. There were 3 minor bleedings in the acenocoumarol and 4 minor bleedings in the warfarin groups, while one major bleedings occurred in both groups. Conclusions: The INR values were more stable in the warfarin group than in the acenocumarole group. In both groups the rate of complete vein recanalization was related to the rate of optimally stable INR values within the therapeutic range. Orv. Hetil., 2012, 153, 786–790.

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 In lower limb deep vein thrombosis; it is important to identify proximal from distal deep vein thrombosis as it carries the highest risk of pulmonary embolism. It is known that D-dimer has a great role in deep vein thrombosis diagnosis. Yet, the use of D-dimer to predict the location of deep vein thrombosis and the risk of pulmonary embolism in deep vein thrombosis patients has not been investigated before. Objective To address the correlation between D-dimer and the location of deep vein thrombosis and to study the efficacy of D-dimer to predict risk of PE in patients with proximal or extensive deep vein thrombosis. Method We included 110 consecutive patients who were hospitalized with the diagnosis of deep vein thrombosis, with or without a concomitant diagnosis of PE, and with D-dimer measured at initial presentation. We categorized the location of deep vein thrombosis as: distal, proximal, and extensive. In the analysis, patients were grouped into high-risk (patients with Proximal or Extensive deep vein thrombosis and pulmonary embolism) and low risk group (patients without pulmonary embolism). Results There was no significant association between D-dimer level and the location of deep vein thrombosis (p=0.519). However, D-dimer level was greater among patients with pulmonary embolism (9.6mg/L) than among patients without pulmonary embolism (7.4mg/L), (p=0.027). D-dimer was a significant predictor of pulmonary embolism as patients with proximal or extensive deep vein thrombosis had 8-folds increased risk of pulmonary embolism than patients with D-dimer less than 4.75mg/L (OR=7.9, p=0.013). Conclusion Though D-dimer was not significantly associated with the location of deep vein thrombosis, it was a significant predictor of pulmonary embolism in patients hospitalized with proximal or extensive deep vein thrombosis.

Limb Deep Vein Thrombosis

A 75-year-old woman with a history of intracranial haemorrhage, atrial fibrillation and coronary artery bypass graft underwent elective left atrial appendage occlusion (LAAO) for stroke prevention. The procedure was successful, however on the third postoperative day, she presented with a lymph leak at the right femoral venous access site. She was admitted for conservative management of the lymph leak with immobility and intravenous fluids. Her inpatient stay was complicated by a right lower limb deep vein thrombosis (DVT), left middle cerebral artery territory ischaemic stroke, pulmonary emboli (PEs) and a splenic infarction. The mechanism of the systemic emboli was that of paradoxical emboli from the DVT passing through an interatrial septal defect created as part of the LAAO procedure, a previously unreported complication of LAAO. She was managed with 6 months of low-dose oral anticoagulation for treatment of DVT and PE and has made a full neurological recovery.
