[PMID: 39003445 PMCID: PMC11245768 DOI: 10.1186/s13019-024-02878-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2024] [Accepted: 06/15/2024] [Indexed: 07/15/2024] Open
Abstract
BACKGROUND Deep venous thrombosis (DVT) is a serious public health issue that threatens human health and economic development. Presently, differences in the prevalence of DVT among individuals from different nationalities, residents of high-altitude areas, and those consuming any special diet are unknown. Therefore, we aimed to elucidate the prevalence of and the associated risk factors for DVT in hospitalized patients in the plateau areas. METHODS The subjects were hospitalized patients in three grade III-a hospitals in the Qinghai Province, China, during January-October 2020. The demographic, clinical, and laboratory data were collected at admission, and ultrasonography of the bilateral lower extremities was performed. The hospital stay-duration was recorded at the time of discharge. RESULTS A total of 3432 patients were enrolled, of which 159 (4.60%) were diagnosed with DVT. The age of > 50 years (OR = 2.434, 95% CI: 1.521-3.894252, P < 0.001), residence altitude of ≥ 3000 m (OR = 2.346, 95% CI: 1.239-4.440, P = 0.009), D-dimer level of ≥ 0.5 mg/L (OR = 2.211, 95% CI: 1.547-3.161, P < 0.001), presence of comorbidities (OR = 1.904, 95% CI: 1.386-2.705, P < 0.001), a history of varicose veins (OR = 1.990, 95% CI: 0.959-4.128, P = 0.045), and current medications (OR = 2.484, 95% CI: 1.778-3.471, P < 0.001) were identified as risk factors for DVT in these plateau areas. CONCLUSION The prevalence of DVT in the hospitalized patients of the studied plateau areas was 4.60%. We recommend considering individualized risk stratification (age > 50 years, residence altitude ≥ 3000 m, a history of varicose veins, D-dimer level ≥ 0.5 mg/L, current medications, and comorbidities) for patients at the time of admission.

Abstract
The Society for Vascular Surgery, the American Venous Forum, and the American Vein and Lymphatic Society recently published Part I of the 2022 clinical practice guidelines on varicose veins. Recommendations were based on the latest scientific evidence researched following an independent systematic review and meta-analysis of five critical issues affecting the management of patients with lower extremity varicose veins, using the patients, interventions, comparators, and outcome system to answer critical questions. Part I discussed the role of duplex ultrasound scanning in the evaluation of varicose veins and treatment of superficial truncal reflux. Part II focuses on evidence supporting the prevention and management of varicose vein patients with compression, on treatment with drugs and nutritional supplements, on evaluation and treatment of varicose tributaries, on superficial venous aneurysms, and on the management of complications of varicose veins and their treatment. All guidelines were based on systematic reviews, and they were graded according to the level of evidence and the strength of recommendations, using the GRADE method. All ungraded Consensus Statements were supported by an extensive literature review and the unanimous agreement of an expert, multidisciplinary panel. Ungraded Good Practice Statements are recommendations that are supported only by indirect evidence. The topic, however, is usually noncontroversial and agreed upon by most stakeholders. The Implementation Remarks contain technical information that supports the implementation of specific recommendations. This comprehensive document includes a list of all recommendations (Parts I-II), ungraded consensus statements, implementation remarks, and best practice statements to aid practitioners with appropriate, up-to-date management of patients with lower extremity varicose veins.

Thromboembolic outcomes are decreased with the use of a standardized venous thromboembolism risk assessment and prophylaxis protocol for patients undergoing superficial venous procedures. J Vasc Surg Venous Lymphat Disord 2023; 11:928-937.e1. [PMID: 37127256 DOI: 10.1016/j.jvsv.2023.04.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2023] [Revised: 04/11/2023] [Accepted: 04/21/2023] [Indexed: 05/03/2023]
Abstract
OBJECTIVE Patients with venous insufficiency can be treated with ablation or phlebectomy, or both. Patients undergoing superficial venous procedures have an elevated risk of deep vein thrombosis (DVT) and pulmonary embolism (PE). At our institution, we initiated a standardized protocol in which patients with a Caprini score (2005 version) of ≥8 are treated with 1 week of prophylactic anticoagulation after the procedure. Duplex ultrasound was performed at 1 week and then within 90 days after the procedure. This aim of the present study was to determine the thrombotic and clinical outcomes after superficial vein procedures using a standardized protocol for DVT/PE risk assessment and prophylaxis. METHODS We performed a retrospective analysis of prospectively collected data of superficial vein procedures from 2015 to 2021 at a single center. The patient demographics, CEAP (Clinical-Etiology-Anatomy-Pathophysiology) clinical class, venous clinical severity score, patient-reported outcomes, treatment type, Caprini scores, pre- and postoperative anticoagulation use, and outcomes were collected. Descriptive statistics were used for the patient demographics, procedure details, and unadjusted surgical outcomes. Multivariable logistic regression was used to evaluate the relationship between procedure type and DVT and PE after adjusting for patient characteristics, disease severity, periprocedural anticoagulation, and Caprini score. RESULTS A total of 1738 limbs were treated with ablation (n = 820), phlebectomy (n = 181), or ablation and phlebectomy (n = 737). More patients were women (67.1%) and White (90.9%). The overall incidence of DVT/PE was 1.4%. Patients undergoing ablation with phlebectomy had higher rates of DVT/PE (2.7%) than those undergoing ablation (0.2%) or phlebectomy alone (1.7%; P < .01). However, only 30% of DVTs were above the knee. On multivariate analysis, only the procedure type predicted for DVT/PE. However, patients undergoing ablation and phlebectomy achieved better patient-reported outcomes (Caprini score, 5.9) compared with those undergoing ablation (Caprini score, 7.2) or phlebectomy (Caprini score, 7.9) alone (P < .01). The best improvement in the venous clinical severity score was seen with phlebectomy alone. CONCLUSIONS The expected difference in the DVT/PE rates between high- and low-risk groups did not materialize in our patients, perhaps secondary to the additional chemoprophylaxis prescribed for the high-risk cohort (Caprini score, ≥8). These results call for a randomized trial to assess the efficacy of a standardized protocol in the reduction of DVT/PE after superficial vein procedures.

Abstract
OBJECTIVE Estimation of the specific thresholds of the Caprini risk score (CRS) that are associated with the increased incidence of venous thromboembolism (VTE) across different specialties, including identifying the highest level of risk. BACKGROUND Accurate risk assessment remains an important but often challenging aspect of VTE prophylaxis. One well-established risk assessment model is CRS, which has been validated in thousands of patients from many different medical and surgical specialties. METHODS A search of MEDLINE and the Cochrane Library was performed in March 2022. Manuscripts that reported on (1) patients admitted to medical or surgical departments and (2) had their VTE risk assessed by CRS and (3) reported on the correlation between the score and VTE incidence, were included in the analysis. RESULTS A total of 4562 references were identified, and the full text of 202 papers was assessed for eligibility. The correlation between CRS and VTE incidence was reported in 68 studies that enrolled 4,207,895 patients. In all specialties, a significant increase in VTE incidence was observed in patients with a CRS of ≥5. In most specialties thresholds of ≥7, ≥9, and ≥11 to 12 were associated with dramatically increased incidences of VTE. In COVID-19, cancer, trauma, vascular, general, head and neck, and thoracic surgery patients with ≥9 and ≥11 to 12 scores the VTE incidence was extremely high (ranging from 13% to 47%). CONCLUSION The Caprini score is being used increasingly to predict VTE in many medical and surgical specialties. In most cases, the VTE risk for individual patients increases dramatically at a threshold CRS of 7 to 11.

Comparison of the predictive power of the 2005 and 2010 Caprini risk assessment models for deep vein thrombosis in Chinese orthopedic patients at admission: A prospective cohort study. Thromb Res 2023; 222:1-6. [PMID: 36542941 DOI: 10.1016/j.thromres.2022.11.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2022] [Revised: 10/10/2022] [Accepted: 11/02/2022] [Indexed: 12/12/2022]
Abstract
INTRODUCTION Several DVT risk assessment tools have been developed and validated to stratify the patients. The 2005 and 2010 Caprini risk assessment models (RAMs) proved reliable in detecting deep vein thrombosis (DVT) and are widely used worldwide. Although the 2010 version was recently modified, the 2005 version is still more exact and popular in the surgical population. This study aimed to compare the predictive power of the 2005 and 2010 Caprini RAMs in Chinese orthopedic patients at admission and describe the incidence of DVT during hospitalization. STUDY DESIGN This prospective cohort study involved 2733 patients from the Arthritis Clinic and Research Center, Orthopedics and Traumatology Department, Orthopedic Oncology Department, and Spinal Surgery Department of Peking University People's Hospital from September 2018 to January 2019. The DVT risk scores and levels were determined for all patients using the 2005 and 2010 Caprini RAMs at admission. The sensitivity and specificity of the two tools were calculated. The patients were divided into the screened and unscreened groups according to whether or not a Doppler ultrasound (DUS) was performed. Depending upon the DUS results, the patients were divided into the DVT and non-DVT groups. The receiver operation characteristic (ROC) curve and the area under the curve (AUC) were evaluated to compare the predictive power. RESULTS Eighty-four patients had DVT in the four orthopedic departments, and the incidence of DVT was 3.1 %-17.2 %. The scores between the 2005 and 2010 Caprini RAMs differed (P < 0.001) among orthopedic patients at admission. Among DVT patients, the highest-risk patients accounted for 63.5 % and 52.9 % based on the 2005 and 2010 Caprini RAMs, respectively. The AUCs of the 2005 and 1020 Caprini RAMs were 0.669 ± 0.030 and 0.648 ± 0.032, respectively. There were no significant differences between the two ROC curves (P = 0.164). CONCLUSION The 2005 and 2010 Caprini RAMs showed a similar predictive power in detecting DVT, but neither met the high sensitivity criteria for screening DVT in orthopedic patients. The incidence of DVT in orthopedic patients was relatively high during hospitalization.

Abstract
Background: Although venous thromboembolism (VTE) is rare, including deep vein thrombosis (DVT) and pulmonary embolism (PE), it is a catastrophic complication after spinal surgery. This study was aimed to investigate the risk factors and incidence of VTE after thoracolumbar spine surgery (TLSS). Methods: We retrieved the data of 8697 patients >20 years old who underwent TLSS between 2000 and 2013 from Taiwan’s Longitudinal Health Insurance Database 2000. Each patient was randomly frequency-matched with four individuals who did not undergo TLSS by age, sex, and index year (the control group). Results: The incidence rates of VTE in the TLSS and control groups were 1.84 and 0.69 per 1000 person-years, respectively. The TLSS group had a higher VTE risk (adjusted HR (aHR): 2.13, 95% confidence interval [95%CI]: 1.41−3.21), DVT (aHR: 2.20, 95%CI: 1.40−3.46), and PE (aHR: 1.60, 95%CI: 0.68−3.78) than the control group. The correlated risk factors of VTE included older age (50−64 years: aHR: 2.16, 95%CI: 1.14−4.09; ≥65 years: aHR: 3.18, 95%CI: 1.65−6.13), a history of cancer (aHR: 2.96, 95%CI: 1.58−5.54), heart failure (aHR: 2.19, 95%CI: 1.27−3.78), and chronic kidney disease (aHR: 1.83, 95%CI: 1.18−2.83). Conclusions: The overall VTE risk following TLSS was less than 2% but correlated with certain risk factors. This information could help the spine surgeon help the patient prevent this fatal complication.

Abstract
Venous thromboembolic complications (VTEO) after modern minimally invasive superficial vein interventions are an infrequent but very dramatic event. This article presents a review of the literature, covering the issues of prevalence, prognosis and pharmacological prevention of VTEO. The performed studies demonstrate that the incidence of symptomatic thrombotic complications after endovenous thermal obliteration does not exceed 0,5%, but taking into account asymptomatic thermally induced thromboses and subclinical occlusions of the muscular veins of the lower leg, this figure can exceed 10%. There is a high heterogeneity of the data, possibly due to differences in the individual risk of VTEO. The most validated tool for assessing the latter is the Caprini Scale, which has not been sufficiently studied in the surgical treatment of varicose veins. The administration of prophylactic doses of anticoagulants after thermal obliteration of saphenous veins is widely used in routine clinical practice, despite the lack of convincing evidence for the appropriateness of this approach. In recent years, the use of direct oral anticoagulants against the official instruction (off-label) has gained great popularity as an alternative to heparin. The largest evidence base has accumulated for the use of rivaroxaban 10 mg, which is associated with high efficacy and safety. Based on completed clinical trials, it is not possible to formulate unequivocal recommendations for prophylactic anticoagulant doses after thermal obliteration of superficial veins at this time. Additional studies are required to identify patients with an individually increased risk of thrombosis in whom prophylactic doses of anticoagulants may be of maximum benefit.

Abstract
INTRODUCTION Venous Thromboembolism (VTE) is a possible complication after varicose vein surgery, reported after both open and endovascular interventions. Nonetheless, there are no internationally accepted recommendations regarding postoperative VTE prevention strategies, with some authors advocating for its use, while others recommend against it. This study aims to systematically review current evidence on the efficacy and safety of chemothromboprophylactic strategies after varicose vein surgery. EVIDENCE ACQUISITION A literature search was performed on the MEDLINE, Scopus, SciELO and Web of Science databases, which returned 532 studies. Ten studies were included. Data were extracted using piloted forms. EVIDENCE SYNTHESIS A total of 6929 patients were included for analysis, out of which 70.4% were treated by open surgery (n=4878) and 29.6% by endovenous procedures (n=2051; 79.1% EVLA; 20.9% RFA). VTE chemothromboprophylaxis was performed in 76.3% of the patients (n=5284), from which 62.5% were treated by open surgery (n=3301) and 37.5% by endovenous interventions (n=1983). Among those treated by open surgery, reported deep venous thrombosis (DVT) rates ranged between 0-6.25%, while pulmonary embolism (PE) was reported in 0-0.07% of the cases. Regarding endovenous interventions, EHIT and DVT rates ranged between 0-2.5% and 0-0.9%, respectively, with no cases of PE described. The remaining 23.7% of the patients did not underwent VTE chemothromboprophylaxis (n=1645), with DVT and PE rates after open surgery ranging between 0-5.17% and 0-1.48%, respectively. Only one study reported thrombotic complications after endovenous interventions in this subgroup of patients, with post-operative EHIT rates of 7.3%, and no information regarding PE or DVT. Bleeding complications were higher in patients undergoing chemothromboprophylaxis (0-10.2%) when compared to those who did not (0-0.18%), and were more frequent after endovenous interventions (0-10.2% versus 0-0.75% after open surgery). CONCLUSIONS VTE is a possible complication after both open and endovascular varicose vein procedures, although overall VTE complications occur less frequently after endovascular interventions. There's a clear heterogeneity regarding peri and postoperative chemoprophylaxis regimens used. Further studies are required to stratify risk factors and indications for chemothromboprophylaxis after varicose vein surgery.
