Ann Vasc Surg 2024; 108:266-278. [PMID: 38942376 DOI: 10.1016/j.avsg.2024.04.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2023] [Revised: 03/07/2024] [Accepted: 04/06/2024] [Indexed: 06/30/2024]
Abstract
OBJECTIVE To examine the efficacy of antegrade and retrograde approaches with the AngioJet thrombectomy device for the treatment of acute lower limb deep vein thrombosis (DVT) and to evaluate the necessity of filter placement. METHODS The clinical data of patients with acute lower limb DVT treated with the AngioJet device from January 2021 to June 2023 were retrospectively analyzed. The patients were divided into the antegrade and retrograde treatment groups according to the surgical approach and the direction of valve opening. The thrombosis interception rate of the filter, incidence of pulmonary embolism (PE), thrombectomy effectiveness, venous obstruction rate, and thrombosis recurrence rate of each treatment group were evaluated. In addition, factors affecting patency were analyzed. RESULTS AngioJet was employed for 84 patients with acute lower limb DVT, treating a total of 88 limbs. The thrombosis interception rate of the filter was 35.7% (30 patients). The incidence of new PE or PE exacerbation was 6.0% (5 patients), and a filter retrieval rate of 97.6% (82 patients) was detected. Thrombus removal of grade III occurred in 35 (64.8%) of the 54 limbs (61.4%) in the antegrade treatment group versus 13 (38.2%) of the 34 limbs (38.6%) in the retrograde treatment group (P < 0.05). At 3 months, venous patency and bleeding events involved 52 (96.3%) and 4 (7.4%) limbs in the antegrade treatment group, respectively, versus 29 (85.3%) and 2 (5.9%) in the retrograde treatment group, respectively (P > 0.05). Regression analysis was performed to determine factors that may affect 3-month patency in both groups. Statistically significant linear relationships were found between 3-month patency and thrombus removal rate [odds ratio [OR] = 0.546 (0.326, 0.916)], thrombus formation time [OR = 1.018 (1.002, 1.036)], and preoperative thrombosis score [OR = 1.012 (1.002, 1.022)] in the antegrade treatment group, as well as thrombus removal rate [0.473 (0.229, 0.977)] in the retrograde treatment group. In regression analysis of factors affecting patency in both groups and the venous clinical severity score/Villalta score, a statistically significant linear relationship was found between thrombus formation time and the venous clinical severity score in the antegrade treatment group [0.576 (0.467, 0.710)]. CONCLUSIONS Both antegrade and retrograde approaches are safe and effective for the treatment of acute lower limb DVT. There are no differences in 3-month deep vein patency and post-thrombotic syndrome (PTS) incidence rates. Individuals with acute lower limb DVT are at high risk of thrombus shedding after treatment with AngioJet thrombectomy, and placement of a vena cava filter (VCF) is recommended for effective interception.

Abstract
We compared the risks and benefits of COVID-19 vaccines using a causal pathway analysis to weigh up possible risk factors of thromboembolic events post-vaccination. The self-controlled case series (SCCS) method examined the association between thromboembolic events and vaccination while a case-control study assessed the association between thromboembolic events and COVID-19, addressing under-reported infection data issues. The net vaccine effect was estimated using results from SCCS and case-control studies. We used electronic health record data from Corewell Health (16,640 subjects in SCCS and 106,143 in case-control). We found increased risks of thromboembolic events post-vaccination (incidence rate ratio: 1.19, 95% CI: [1.08, 1.31] after the first dose; 1.22, 95% CI: [1.11, 1.34] after the second dose). Vaccination attenuated infection-associated thromboembolic risks (odds ratio: 4.65, 95% CI: [4.18, 5.17] in unvaccinated vs 2.77, 95% CI: [2.40, 3.24] in vaccinated). After accounting for vaccine efficacy and protection against infection-associated thromboembolic events, vaccination decreases thromboembolic event risk, especially during high infection rate periods.

Abstract
ABSTRACT Background A recent clinical trial suggested aspirin is a viable alternative to enoxaparin for venous thromboembolism (VTE) prophylaxis in patients after orthopedic trauma. The initial impact of these findings on VTE prophylaxis prescribing is unknown. The study aimed to evaluate stated VTE prophylaxis prescribing patterns among clinicians who treat patients after orthopedic trauma. Methods For this clinical vignette survey, we recruited surgeons and advanced practice providers who prescribed VTE prophylaxis to patients with orthopedic trauma across 40 states. Clinicians were shown seven clinical vignettes describing hypothetical patients with orthopedic trauma based on their fracture type, treatment, VTE risk factors, additional injuries and health insurance status. We assessed the stated VTE prophylaxis medications prescribed in-hospital and at discharge, patient factors associated with changes in medication prescribing preferences and practice variation by specialty and provider training. Results Among the 287 respondents, the median age was 43 years (IQR, 38-50), and 154 (weighted average, 63%) were men. For in-hospital VTE prophylaxis, enoxaparin was prescribed in 83% of the presented scenarios, and aspirin was prescribed in 13% (p<0.001). At discharge, aspirin was prescribed more frequently than enoxaparin (50% vs 41%, p<0.001). Healthcare providers with an aspirin discharge preference were 12% more likely to switch to enoxaparin if the patient had additional VTE risk factors, such as obesity (95% CI 4% to 19%, p=0.005). Conclusions Despite new clinical evidence, in-hospital VTE prophylaxis prescribing practices for patients with orthopedic trauma remain consistent with those reported a decade ago. However, compared with historical data, clinicians have significantly increased their preference for aspirin for thromboprophylaxis at discharge-unless the patient has additional thromboembolic risk factors. Level of evidence 5-expert opinion.

Abstract
Background: Current literature demonstrates prophylactic enoxaparin to be efficacious in reducing venous thromboembolism (VTE) rates without significantly increasing risk for bleeding complications. Despite this evidence, prophylactic enoxaparin doses are frequently withheld for surgery or procedures. This exploratory study aims to quantify the risk of a VTE event in trauma patients associated with missed doses of prophylactic enoxaparin. Methods: This retrospective cohort study evaluated trauma patients admitted to our Level 1 trauma center from January 1, 2012 to January 31, 2021. A 1:1 propensity match with ten variables was performed to compare patients receiving prophylactic enoxaparin that had a VTE and those that did not. The primary outcome was a VTE event. Results: 493 patients met inclusion criteria; 1:1 propensity score matching was performed resulting in a cohort of 184 patients. The percentage of patients that missed a prophylactic enoxaparin dose in the VTE group was higher than the no VTE group (34.8% vs 21.7%, P = 0.049). This is consistent when examining total missed doses (P = 0.038) and consecutively missed doses (P = 0.035). The odds of having a VTE for patients that missed at least one dose or more of enoxaparin are nearly two times greater (OR 1.92, 95% CI 0.997, 3.7). Conclusion: Missing enoxaparin doses significantly increases the risk of VTE in matched populations. Most prophylactic enoxaparin doses were held for procedures, and not for bleeding events. Trauma teams should carefully weigh the risk of bleeding complications associated with continuing enoxaparin prophylaxis against the significant thromboembolic risk of withholding it.

Abstract
INTRODUCTION Venous thromboembolism following orthopedic trauma surgery remains prevalent despite prophylaxis being a standard of care. Enoxaparin injection is a commonly utilized prophylaxis regimen among high-risk patients. Patient-reported rates of nonadherence and barriers to enoxaparin use are not described in the literature. A better understanding of these barriers and their impact on adherence to post-discharge prophylaxis regimens may shed light on persistent outcomes gaps. MATERIALS AND METHODS Semi-structured interviews were administered to adult patients prescribed prophylactic enoxaparin and presenting to orthopedic surgery outpatient clinic at an urban level 1 trauma center for a post-operative appointment following traumatic injury from April to July 2023. Patients self-reported their age, gender, race, and mobility. Inductive thematic analysis with three-reviewer consensus identified common barriers among responses. Adherence rates were calculated by dividing patients' estimated number of missed doses over total prescribed doses at the point of inquiry. RESULTS We identified 154 eligible patients through chart review, and 50 enrolled and interviewed. Participants had a mean age of 37 years. Of 50 participants, 20 identified as female; 25 identified as Black or African American, 16 as White, 5 as Hispanic, 2 as Asian, and 2 as multiracial. Twenty-one participants were non-ambulatory at time of interview. Mean and median patient-reported adherence were 64.5 % (SD 35.5) and 70.5 % (IQR 33-100) respectively. Five patients reported complete nonadherence, while 17 patients reported perfect adherence. Every participant reporting complete nonadherence identified as Black or African American, as compared to 8 out of 17 reporting perfect adherence. Despite acknowledging a twice-daily prescription, 17 patients reported once-daily rather than twice-daily use. Inductive thematic analysis revealed the following six barriers to prophylaxis adherence (number of participants reporting): Inconvenience (18 patients), Pain (16), Fear (12), Acquisition (7), Bruising (7), and Mechanism (7). Altogether, 40 patients endorsed at least one barrier to adherence. DISCUSSION & CONCLUSIONS Most patients face barriers to adherence with post-discharge prophylactic enoxaparin, and the resultant rates of adherence are low. This may contribute to persistent outcomes gaps in the orthopedic trauma population despite prophylaxis standards. Changes in prescribing patterns and patient engagement techniques may improve post-operative thromboembolic outcomes.

Abstract
BACKGROUND Combat casualties receiving damage-control laparotomy at forward deployed, resource-constrained US military Role 2 (R2) surgical units require multiple evacuations, but the added risk of venous thromboembolism (VTE) in this population has not been defined. To fill this gap, we retrospectively analyzed 20 years of Department of Defense Trauma Registry data to define the VTE rate in this population. METHODS Department of Defense Trauma Registry from 2002 to 2023 was queried for US military combat casualties requiring damage-control laparotomy at R2. All deaths were excluded in subsequent analysis. Rates of VTE were assessed, and subgroup analysis was performed on patients requiring massive transfusion. RESULTS Department of Defense Trauma Registry (n = 288) patients were young (mean age, 25 years) and predominantly male (98%) with severe (mean Injury Severity Score, 26), mostly penetrating injury (76%) and high mortality. Venous thromboembolism rate was high: 15.8% (DVT, 10.3%; pulmonary embolism, 7.1%). In the massively transfused population, the VTE rate was even higher (26.7% vs. 10.2%, p < 0.001). CONCLUSION This is the first report that combat casualties requiring damage-control laparotomy at R2 have such high VTE rates. Therefore, for military casualties, we propose screening ultrasound upon arrival to each subsequent capable echelon of care and low threshold for initiating thromboprophylaxis.

Abstract
INTRODUCTION Pelvic fractures are associated with a high risk of venous thromboembolism (VTE). Among treatment options, including pelvic angioembolization (PA), preperitoneal pelvic packing (PPP), and pelvic open reduction internal fixation (ORIF), PPP has been postulated as a VTE risk factor. We aimed to characterize the risk of VTE among pelvic fracture patients receiving PPP, PA or ORIF. METHODS We used observational data from a 17-site Consortium of Leaders in the Study of Traumatic Thromboembolism (CLOTT) study group, a US level I trauma center collaborative working to identify factors associated with posttraumatic VTE, deep venous thrombosis, pulmonary embolism, or pulmonary thrombosis. The CLOTT criteria included age 18 to 40 years with at least one independent VTE risk factor. We compared outcomes of PPP, PA, and pelvic ORIF to reference of no pelvic intervention. Our primary outcome was VTE. A competing risk analysis was performed. RESULTS Among 1,387 pelvic fracture patients, VTE incidence was 5.6%. The ORIF patients were most likely to develop VTE (24.7%), while VTE incidence for PPP was 9.0% and 2.6% for PA. After multivariate, risk-competing analysis, none of the three treatment interventions for pelvic fractures were significantly associated with VTE. Initiation of VTE prophylaxis in the first 24 hours of admission independently halved VTE incidence (hazard ratio, 0.55; confidence interval, 0.33-0.91). CONCLUSION Pelvic fracture interventions do not appear to be independent risk factors for VTE in our study. Initiation of VTE pharmacoprophylaxis within the first 24 hours of admission remains critical to significantly decreasing VTE formation in this high-risk population.

Abstract
INTRODUCTION There are no clear recommendations for the perioperative timing and initiation of venous thromboembolism pharmacologic prophylaxis (VTEp) among polytrauma patients undergoing high-risk bleeding orthopedic operative intervention, leading to variations in VTEp administration. Our study examined the association between the timing of VTEp and VTE complications in polytrauma patients undergoing high-risk operative orthopedic interventions nationwide. METHODS We performed a retrospective cohort study of trauma patients 18 years or older who underwent high-risk bleeding operative orthopedic interventions for pelvic, hip, and femur fractures within 24 hours of admission at American College of Surgeons-verified trauma centers using the 2019-2020 American College of Surgeons Trauma Quality Improvement Program databank. We excluded patients with a competing risk of nonorthopedic surgical bleeding. We assessed operative orthopedic polytrauma patients who received VTEp within 12 hours of orthopedic surgical intervention compared with VTEp received beyond 12 hours of intervention. The primary outcome assessed was overall VTE events. Secondary outcomes were orthopedic reinterventions within 72 hours after primary orthopedic surgery, deep venous thromboembolism, and pulmonary embolism rates. RESULTS The study included 2,229 patients who underwent high-risk orthopedic operative intervention. The median time to VTEp initiation was 30 hours (interquartile range, 18-44 hours). After adjustment for baseline patient, injury, and hospital characteristics, VTEp initiated more than 12 hours from primary orthopedic surgery was associated with increased odds of VTE (adjusted odds ratio, 2.02; 95% confidence interval, 1.08-3.77). Earlier initiation of prophylaxis was not associated with an increased risk for surgical reintervention (hazard ratio, 0.90; 95% confidence interval, 0.62-1.34). CONCLUSION Administering VTEp within 24 hours of admission and within 12 hours of major orthopedic surgery involving the femur, pelvis, or hip demonstrated an associated decreased risk of in-hospital VTE without an accompanying elevated risk of bleeding-related orthopedic reintervention. Clinicians should reconsider delays in initiating or withholding perioperative VTEp for stable polytrauma patients needing major orthopedic intervention.

Abstract
BACKGROUND This study aimed to evaluate whether lower extremity (LE) amputation among civilian casualties is a risk factor for venous thromboembolism. METHODS All patients with severe LE injuries (AIS ≥3) derived from the ACS-TQIP (2013-2020) were divided into those who underwent trauma-associated amputation and those with limb salvage. Propensity score matching was used to mitigate selection bias and confounding and compare the rates of pulmonary embolism (PE) and deep vein thrombosis (DVT). RESULTS A total of 145,667 patients with severe LE injuries were included, with 3443 patients requiring LE amputation. After successful matching, patients sustaining LE amputation still experienced significantly higher rates of PE (4.2% vs. 2.5%, p < 0.001) and DVT (6.5% vs. 3.4%, p < 0.001). A sensitivity analysis examining patients with isolated major LE trauma similarly showed a higher rate of thromboembolic complications, including higher incidences of PE (3.2% vs. 2.0%, p = 0.015) and DVT (4.7% vs. 2.6%, p < 0.001). CONCLUSIONS In this nationwide analysis, traumatic lower extremity amputation is associated with a significantly higher risk of VTE events, including PE and DVT.

Abstract
Background and objective Studies assessing the incidence of venous thromboembolic (VTE) events in the setting of massive balanced transfusions and/or tranexamic acid (TXA) infusion have yielded varied outcomes. In light of this, we conducted this study to examine the incidence of VTEs in trauma patients requiring blood products, and to identify the risk factors for VTE and mortality in this population. Methods We performed a retrospective analysis of trauma patients admitted to our level 1 trauma center from January 2013 to September 2023. Clinical characteristics were compared between patients who developed VTE and those who did not. A regression analysis of potential variables associated with the development of VTEs and mortality was performed. Results Among 1305 patients (mean age: 42.4 ± 18.8 years) receiving blood products within the initial 24 hours, 4.3% (56 patients) developed a VTE. Patients with VTE experienced prolonged ICU and hospital stays and ventilation duration (p<0.001). They were also noted to have delayed initiation of VTE prophylaxis (104.2 vs. 50.3 hours, p<.001). Prolonged ventilation >7 days was the sole significant factor associated with VTE in multivariate regression analysis [odds ratio (OR): 6.2, p=0.004]. Early TXA administration (within four hours) showed a higher association with VTE than TXA within 24 hours (OR: 2.1, p=0.07 vs. OR 1.6, p=0.22). Massive transfusion was found to increase VTE risk (OR: 2.65, p<0.001). Severe head and neck (OR: 6.0, p=0.002) and chest (OR: 3.8, p=0.01) injuries were key predictors of mortality, while TXA was not significantly associated with mortality in the multivariate model. Conclusions Our study revealed an elevated risk of VTE in patients requiring massive transfusion protocol (MTP, ≥6 units). Early TXA administration was neither associated with increased VTE risk in MTP patients nor increased mortality risk. Strategies directed at reducing the risk of VTE in massively transfused patients while maintaining the survival benefits of balanced resuscitation and TXA need to be devised.

Abstract
BACKGROUND Current guidelines recommend low-molecular-weight heparin for thromboprophylaxis after orthopaedic trauma. However, recent evidence suggests that aspirin is similar in efficacy and safety. To understand patients' experiences with these medications, we compared patients' satisfaction and out-of-pocket costs after thromboprophylaxis with aspirin versus low-molecular-weight heparin. METHODS This study was a secondary analysis of the PREVENTion of CLots in Orthopaedic Trauma (PREVENT CLOT) trial, conducted at 21 trauma centers in the U.S. and Canada. We included adult patients with an operatively treated extremity fracture or a pelvic or acetabular fracture. Patients were randomly assigned to receive 30 mg of low-molecular-weight heparin (enoxaparin) twice daily or 81 mg of aspirin twice daily for thromboprophylaxis. The duration of the thromboprophylaxis, including post-discharge prescription, was based on hospital protocols. The study outcomes included patient satisfaction with and out-of-pocket costs for their thromboprophylactic medication measured on ordinal scales. RESULTS The trial enrolled 12,211 patients (mean age and standard deviation [SD], 45 ± 18 years; 62% male), 9725 of whom completed the question regarding their satisfaction with the medication and 6723 of whom reported their out-of-pocket costs. The odds of greater satisfaction were 2.6 times higher for patients assigned to aspirin than those assigned to low-molecular-weight heparin (odds ratio [OR]: 2.59; 95% confidence interval [CI]: 2.39 to 2.80; p < 0.001). Overall, the odds of incurring any out-of-pocket costs for thromboprophylaxis medication were 51% higher for patients assigned to aspirin compared with low-molecular-weight heparin (OR: 1.51; 95% CI: 1.37 to 1.66; p < 0.001). However, patients assigned to aspirin had substantially lower odds of out-of-pocket costs of at least $25 (OR: 0.15; 95% CI: 0.12 to 0.18; p < 0.001). CONCLUSIONS Use of aspirin substantially improved patients' satisfaction with their medication after orthopaedic trauma. While aspirin use increased the odds of incurring any out-of-pocket costs, it protected against costs of ≥$25, potentially improving health equity for thromboprophylaxis.

Abstract
Venous thromboembolism (VTE) causes significant morbidity in patients with trauma despite advances in pharmacologic therapy. Prior literature suggests standard enoxaparin dosing may not achieve target prophylactic anti-Xa levels. We hypothesize that a new weight-based enoxaparin protocol with anti-Xa monitoring for dose titration in critically injured patients is safe and easily implemented. Methods This prospective observational study included patients with trauma admitted to the trauma intensive care unit (ICU) from January 2021 to September 2022. Enoxaparin dosing was adjusted based on anti-Xa levels as standard of care via a performance improvement initiative. The primary outcome was the proportion of subtarget anti-Xa levels (<0.2 IU/mL) on 30 mg two times per day dosing of enoxaparin. Secondary outcomes included the dosing modifications to attain goal anti-Xa levels, VTE and bleeding events, and hospital and ICU lengths of stay. Results A total of 282 consecutive patients were included. Baseline demographics revealed a median age of 36 (26-55) years, and 44.7% with penetrating injuries. Of these, 119 (42.7%) achieved a target anti-Xa level on a starting dose of 30 mg two times per day. Dose modifications for subtarget anti-Xa levels were required in 163 patients (57.8%). Of those, 120 underwent at least one dose modification, which resulted in 78 patients (47.8%) who achieved a target level prior to hospital discharge on a higher dose of enoxaparin. Overall, only 69.1% of patients achieved goal anti-Xa level prior to hospital discharge. VTE occurred in 25 patients (8.8%) and major bleeding in 3 (1.1%) patients. Conclusion A majority of critically injured patients do not meet target anti-Xa levels with 30 mg two times per day enoxaparin dosing. This study highlights the need for anti-Xa-based dose modification and efficacy of a pharmacy-driven protocol. Further optimization is warranted to mitigate VTE events.

Abstract
BACKGROUND Risk of venous thromboembolism (VTE) in many trauma patients extends beyond hospitalization, but there is a paucity of evidence to guide the use of post-discharge prophylaxis (PDP). METHODS A retrospective cohort study of trauma patients deemed moderate-to-high risk for VTE (risk assessment profile score [RAP] ≥5) who were prescribed PDP based on an internal clinical guideline assessing injury pattern and mobility status. PDP patients were compared with those that did not receive post-discharge prophylaxis (NPDP). RESULTS 1512 patients were included. PDP group had higher mean RAP score (7.3 vs. 6.4, p < 0.001), more likely to have a complex orthopedic fracture and underwent a longer median hospital (4.7 vs. 2.9 days, p < 0.001). No difference between groups in 90-day VTE (11 [1.5 %] (PDP) vs. 8 [1.0 %] (NPDP), p = 0.50), clinically relevant bleeding (p = 0.58), or readmission (p = 0.46). CONCLUSIONS VTE incidence, clinically relevant bleeding, and readmission 90-days after hospital discharge were low and similar between PDP and NPDP groups. PDP prescribed in a presumably higher VTE risk trauma population may mitigate the long-term risk of VTE.

Abstract
PURPOSE Patients with traumatic brain injury (TBI) are at high risk for venous thromboembolism (VTE). The aim of the present study is to identify factors independently associated with VTE events. Specifically, we hypothesized that the mechanism of penetrating head trauma might be an independent factor associated with increased VTE events when compared with blunt head trauma. METHODS The ACS-TQIP database (2013-2019) was queried for all patients with isolated severe head injuries (AIS 3-5) who received VTE prophylaxis with either unfractionated heparin or low-molecular-weight heparin. Transfers, patients who died within 72 h and those with a hospital length of stay < 48 h were excluded. Multivariable analysis was used as the primary analysis to identify independent risk factors for VTE in isolated severe TBI. RESULTS A total of 75,570 patients were included in the study, 71,593 (94.7%) with blunt and 3977 (5.3%) with penetrating isolated TBI. Penetrating trauma mechanism (OR 1.49, CI 95% 1.26-1.77), increasing age (age 16-45: reference; age > 45-65: OR 1.65, CI 95% 1.48-1.85; age > 65-75: OR 1.71, CI 95% 1.45-2.02; age > 75: OR 1.73, CI 95% 1.44-2.07), male gender (OR 1.53, CI 95% 1.36-1.72), obesity (OR 1.35, CI 95% 1.22-1.51), tachycardia (OR 1.31, CI 95% 1.13-1.51), increasing head AIS (AIS 3: reference; AIS 4: OR 1.52, CI 95% 1.35-1.72; AIS 5: OR 1.76, CI 95% 1.54-2.01), associated moderate injuries (AIS = 2) of the abdomen (OR 1.31, CI 95% 1.04-1.66), spine (OR 1.35, CI 95% 1.19-1.53), upper extremity (OR 1.16, CI 95% 1.02-1.31), lower extremity (OR 1.46, CI 95% 1.26-1.68), craniectomy/craniotomy or ICP monitoring (OR 2.96, CI 95% 2.65-3.31) and pre-existing hypertension (OR 1.18, CI 95% 1.05-1.32) were identified as independent risk factors for VTE complications in isolated severe head injury. Increasing GCS (OR 0.93, CI 95% 0.92-0.94), early VTE prophylaxis (OR 0.48, CI 95% 0.39-0.60) and LMWH compared to heparin (OR 0.74, CI 95% 0.68-0.82) were identified as protective factors for VTE complications. CONCLUSION The identified factors independently associated with VTE events in isolated severe TBI need to be considered in VTE prevention measures. In penetrating TBI, an even more aggressive VTE prophylaxis management may be justified as compared to that in blunt.

Abstract
Background Elevated risk of venous thromboembolism (VTE) in patients with coronavirus disease 2019 (COVID-19) pneumonia has been recognized, while the risk factors associated with VTE in patients with non-COVID-19 pneumonia remain to be defined. This study aimed to conduct a meta-analysis and systematic review following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to identify potential risk factors for VTE in patients with pneumonia from the pre-COVID-19 era. Methods PubMed, EMBASE, and Cochrane Library were searched. Two reviewers performed screening, full-text review, and extraction. Risk factors and odds ratio (OR) were estimated. Results Of 595 articles identified, six studies were included. Pooled analysis suggested that age ≥60 years [OR =2.75, 95% confidence interval (CI): 2.55-2.97, P<0.001], mechanical ventilation (MV) (OR =9.48, 95% CI: 8.24-10.91, P<0.001), hypertension (OR =1.41, 95% CI: 1.09-1.83, P=0.010), diabetes (OR =1.49, 95% CI: 1.36-1.64, P<0.001), heart failure (OR =3.15, 95% CI: 1.05-9.41, P=0.040) and cancer (OR =2.86, 95% CI: 2.07-3.95, P<0.001) were associated with higher risk for deep vein thrombosis in patients with pneumonia. While age ≥60 years (OR =2.46, 95% CI: 2.21-2.73, P<0.001), bacterial pneumonia (OR =3.80, 95% CI: 1.65-8.73, P=0.002), hyperlipidemia (OR =1.55, 95% CI: 1.00-2.41, P=0.049), heart failure (OR =2.70, 95% CI: 2.05-3.56, P<0.001), chronic obstructive pulmonary disease (OR =4.73, 95% CI: 3.11-7.17, P<0.001) and cancer (OR =2.90, 95% CI: 2.39-3.53, P<0.001) were risk factors for pulmonary embolism in patients with pneumonia. Conclusions Patients with non-COVID-19 pneumonia, particularly those with advanced age, MV, cardiovascular comorbidities or cancer, warrant individualized management during hospitalization. Our findings could contribute to refining risk prediction models and further risk stratification for VTE in patients with pneumonia in clinical practice.

Efficacy of the bleeding risk scoring system for optimal prophylactic anticoagulation therapy of venous thromboembolism in trauma patients: a single-center, retrospective, observational cohort study. J Pharm Health Care Sci 2023; 9:48. [PMID: 38111026 PMCID: PMC10729339 DOI: 10.1186/s40780-023-00319-5] [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: 07/25/2023] [Accepted: 11/14/2023] [Indexed: 12/20/2023] Open
Abstract
BACKGROUND We developed a bleeding risk scoring system (BRSS) using prophylactic anticoagulation therapy to comprehensively assess the risk of venous thromboembolism (VTE) in trauma patients. This study evaluated the usefulness of this system in trauma patients, with a focus on minimizing the rate of bleeding events associated with prophylactic anticoagulation therapy. METHODS We retrospectively evaluated the efficacy of BRSS in trauma patients who received prophylactic anticoagulation therapy for VTE at the Kitasato University Hospital Emergency and Critical Care Center between April 1, 2015, and August 31, 2020. To compare the incidence of bleeding events, patients were divided into two groups: one group using the BRSS (BRSS group) and another group not using the BRSS (non-BRSS group). RESULTS A total of 94 patients were enrolled in this study, with 70 and 24 patients assigned to the non-BRSS and BRSS groups, respectively. The major bleeding event rates were not significantly different between the two groups (BRSS group, 4.2%; non-BRSS group, 5.7%; p = 1.000). However, minor bleeding events were significantly reduced in the BRSS group (4.2% vs.27.1%; p = 0.020). Multivariate logistic regression analysis showed that BRSS was not an independent influencing factor of major bleeding events (odds ratio, 0.660; 95% confidence interval: 0.067-6.47; p = 0.721). Multivariate logistic regression analysis showed that BRSS was an independent influencing factor of minor bleeding events (odds ratio, 0.119; 95% confidence interval: 0.015-0.97; p = 0.047). The incidence of VTE did not differ significantly between groups (BRSS group, 4.2%; non-BRSS group, 8.6%; p = 0.674). CONCLUSIONS BRSS may be a useful tool for reducing the incidence of minor bleeding events during the initial prophylactic anticoagulation therapy in trauma patients. There are several limitations of this study that need to be addressed in future research.

Abstract
INTRODUCTION Venous thromboembolism (VTE) remains a significant source of postinjury morbidity and mortality. Beta-hydroxy beta-methylglutaryl-CoA (HMG-CoA) reductase inhibitors (rosuvastatin) significantly reduced pathologic clotting events in healthy populations in a prior trial. Furthermore, acetylsalicylic acid (ASA) has been shown to be noninferior to prophylactic heparinoids for VTE prevention following orthopedic surgery. We hypothesized that a combination of rosuvastatin/ASA, in addition to standard VTE chemoprophylaxis, would reduce VTE in critically ill trauma patients. METHODS This was a double-blind, placebo-controlled, randomized trial, evaluating VTE rates in two groups: ASA + statin (Experimental) and identical placebos (Control). Injured adults, 18-65 years old, admitted to the surgical intensive care unit without contraindications for VTE prophylaxis were eligible. Upon initiation of routine VTE chemoprophylaxis (i.e. heparin/heparin-derivatives), they were randomized to the Experimental or Control group. VTE was the primary outcome. RESULTS Of 112 potentially eligible patients, 33% (n = 37, median new injury severity scale = 27) were successfully randomized, of whom 11% had VTEs. The Experimental group had no VTEs, while the Control group had 6 VTEs (4 PEs and 2 DVTs) in 4 (22%) patients (P = 0.046). The Experimental treatment was not associated with any serious adverse events. Due to the COVID-19 pandemic, the study was interrupted at the second interim analysis at <10% of the planned enrollment, with significance declared at P < 0.012 at that stage. DISCUSSION The combination of ASA and rosuvastatin with standard VTE prophylaxis showed a favorable trend toward reducing VTEs with no serious adverse events. An appropriately powered phase III multicenter trial is needed to further investigate this therapeutic approach. LEVEL OF EVIDENCE Level II, Therapeutic.

Abstract
INTRODUCTION Management of below-knee DVT (BKDVT) in trauma patients is uncertain. We hypothesized that BKDVT can be managed with observation only. METHODS Secondary analysis on trauma inpatients March 2017-September 2019 with risk assessment profile ≥5. Management of BKDVT included observation with ultrasound. BKDVT was compared to above-knee DVT (AKDVT), and BKDVT with progression to AKDVT/PE compared to no progression. RESULTS Of 1988 patients, 136 (6.8%) BKDVT and 23 (1.2%) AKDVT. 7 (6.9%) BKDVT progressed to AKDVT/PE. 6.9% had BKDVT progression, associated with higher ISS (36.7 vs 21.6, p = 0.005), longer prophylaxis delay (121 vs 45 h, p = 0.02) and longer hospital LOS (25.6 vs 7.8, p = 0.01). None experienced post-thrombotic syndrome. CONCLUSION Majority of BKDVT in hospitalized trauma patients did not progress to AKDVT. Observation for progression, rather than treatment, was not associated with increased PE risk or thrombotic sequelae. Observation with serial ultrasound may serve as a practical alternative to anticoagulation in trauma patients with BKDVT.

Abstract
INTRODUCTION Pulmonary embolism (PE) is a recognized cause of death in hospitalized trauma patients, yet less is known about PE after discharge. PATIENTS & METHODS All post-discharge, autopsy-demonstrated, fatal PE resulting from trauma within a large US county over six years were analyzed. Counts, percentages, mean values, SD, and IQR were calculated for all variables. RESULTS 1848 trauma deaths were reviewed, of which 85% had an autopsy. Eighty-five patients died from PE after discharge from their initial injury. 53% were initially treated at non-trauma centers, and 9% did not seek medical assistance. 75% were injured by falling, and most injuries occurred in the lower extremities. 86% had an ISS <16, but 87% needed assistance or were bed-bound after injury, despite 75% having no mobility limitations before the injury. 53% died within one month of injury, and 91% within the first year. Before death, only 11% were prescribed chemical thromboprophylaxis or an antiplatelet agent, and only 8% were diagnosed with venous thromboembolism before death. CONCLUSIONS Fatal PE after discharge typically occurred following activity-limiting lower extremity injuries with an ISS<16.

Abstract
BACKGROUND Race is associated with differences in quality of care process measures and incidence of venous thromboembolism (VTE) in trauma patients. We aimed to investigate if racial disparities exist in the administration of VTE prophylaxis in trauma patients. METHODS We queried the Trauma Quality Improvement Project database from 2017 to 2019. Patients ages ≥16 years old with ISS ≥15 were included. Patients with no signs of life on arrival, any AIS ≥6, hospital length of stay <1 day, anticoagulant use before admission, or without recorded race were excluded. Patients were grouped by race: white, black, Asian, American Indian, and Native Hawaiian or Pacific Islander. The association between VTE prophylaxis administration and race was determined using a Poisson regression model with robust standard errors to adjust for confounders. RESULTS A total of 285,341 patients were included. Black patients had the highest rates of VTE prophylaxis exposure (73.8%), shortest time to administration (1.6 days), and highest use of low molecular weight heparin (56%). Black patients also had the highest incidence of deep vein thrombosis (2.8%) and pulmonary embolism (1.4%). Black patients were 4% more likely to receive VTE prophylaxis than white patients [adj. IRR (95% CI): 1.04 (1.03-1.05), P < .001]. American Indians were 8% less likely to receive VTE prophylaxis [adj. IRR (95% CI): .92 (.88-.97), P < .001] than white patients. No differences between white and Asian or Native Hawaiian or Pacific Islander patients existed. DISCUSSION While black patients had the highest incidence of DVT and PE, they had higher administration rates and earlier initiation of VTE prophylaxis. Further work can elucidate modifiable causes of these differences.

Abstract
BACKGROUND The optimal time to initiate venous thromboembolism prophylaxis (VTEp) for patients with intracranial hemorrhage (ICH) is controversial and must balance the risks of VTE with potential progression of ICH. We sought to evaluate the efficacy and safety of early VTEp initiation after traumatic ICH. METHODS This is a secondary analysis of the prospective multicenter Consortium of Leaders in the Study of Thromboembolism study. Patients with head Abbreviated Injury Scale score of > 2 and with immediate VTEp held because of ICH were included. Patients were divided into VTEp ≤ or >48 hours and compared. Outcome variables included overall VTE, deep vein thrombosis (DVT), pulmonary embolism, progression of intracranial hemorrhage (pICH), or other bleeding events. Univariate and multivariate logistic regressions were performed. RESULTS There were 881 patients in total; 378 (43%) started VTEp ≤48 hours (early). Patients starting VTEp >48 hours (late) had higher VTE (12.4% vs. 7.2%, p = 0.01) and DVT (11.0% vs. 6.1%, p = 0.01) rates than the early group. The incidence of pulmonary embolism (2.1% vs. 2.2%, p = 0.94), pICH (1.9% vs. 1.8%, p = 0.95), or any other bleeding event (1.9% vs. 3.0%, p = 0.28) was equivalent between early and late VTEp groups. On multivariate logistic regression analysis, VTEp >48 hours (odds ratio [OR], 1.86), ventilator days >3 (OR, 2.00), and risk assessment profile score of ≥5 (OR, 6.70) were independent risk factors for VTE (all p < 0.05), while VTEp with enoxaparin was associated with decreased VTE (OR, 0.54, p < 0.05). Importantly, VTEp ≤48 hours was not associated with pICH (OR, 0.75) or risk of other bleeding events (OR, 1.28) (both p = NS). CONCLUSION Early initiation of VTEp (≤48 hours) for patients with ICH was associated with decreased VTE/DVT rates without increased risk of pICH or other significant bleeding events. Enoxaparin is superior to unfractionated heparin as VTE prophylaxis in patients with severe TBI. LEVEL OF EVIDENCE Therapeutic/Care Management; Level IV.

Abstract
INTRODUCTION Patients with traumatic brain injury (TBI) are at risk for developing venous thromboembolic complications. Previous work suggests venous thromboembolism (VTE) prophylaxis with low molecular weight heparin (LMWH) is protective compared to unfractionated heparin (UH) in trauma patients. The purpose of this study was to evaluate the role of body mass index (BMI) and type of pharmacological VTE prophylaxis in patients who develop VTE with severe TBI. METHODS Patients with a severe TBI who received VTE prophylaxis were queried from the 2019 American College of Surgeons Trauma Quality Improvement Program database. Demographics, injury characteristics, timing of VTE prophylaxis, and BMI were collected. Outcome measures include VTE, mortality, and neurosurgical interventions. RESULTS Of the 39,520 patients with severe TBI included in the study, 25,671 received LMWH and 13,849 received UH. Multivariable logistic regression found patients with a BMI 25-29.9 kg/m2 (odds ratio [OR] 1.375; 95% confidence interval [CI] 1.180-1.603; P < 0.0001) and a BMI>30 kg/m2 (OR 1.831; 95% CI 1.570-2.137; P < 0.0001) were independent predictors of VTE. Patients with BMI of 25-29.9 kg/m2 (OR 1.145; 95% CI 1.016-1.289; P = 0.0265) have a higher risk of mortality. For every hour delay in initiation to VTE prophylaxis, patients were 0.2% more likely to develop VTE (OR 1.002; 95% CI 1.002-1.003; P < 0.0001). Patients treated with UH were more likely to develop VTE complications (OR 1.085; 95% CI 1.058-1.112; P < 0.0001) and have increased mortality (OR 1.116; 95% CI 1.094-1.139; P < 0.0001), regardless of BMI and time to initiation of prophylaxis, compared to patients treated with LMWH. CONCLUSIONS In patients with severe TBI, higher BMI was associated with an increased risk of VTE and death. Delay in VTE prophylaxis initiation was associated with an increased risk of VTE. LMWH had a protective association with VTE.

A prospective multicenter analysis across 17 level I trauma centers. Injury 2023; 54:111008.

Abstract
IMPORTANCE The early use of tranexamic acid (TXA) has demonstrated benefit among some trauma patients in hemorrhagic shock. The association between TXA administration and thromboembolic events (including deep vein thrombosis (DVT), pulmonary embolism (PE) and pulmonary thrombosis (PT)) remains unclear. We aimed to characterize the risk of venous thromboembolism (VTE) subtypes among trauma patients receiving TXA and to determine whether TXA is associated with VTE risk and mortality. METHODS We analyzed a prospective, observational, multicenter cohort data from the Consortium of Leaders in the Study of Traumatic Thromboembolism (CLOTT) study group. The study was conducted across 17 US level I trauma centers between January 1, 2018, and December 31,2020. We studied trauma patients ages 18-40 years, admitted for at least 48 h with a minimum of 1 VTE risk factor and followed until hospital discharge or 30 days. We compared TXA recipients to non-recipients for VTE and mortality using inverse probability weighted Cox models. The primary outcome was the presence of documented venous thromboembolism (VTE). The secondary outcome was mortality. VTE was defined as DVT, PE, or PT. RESULTS Among the 7,331 trauma patients analyzed, 466 (6.4%) received TXA. Patients in the TXA group were more severely injured than patients in the non-TXA group (ISS 16+: 69.1% vs. 48.5%, p < 0.001) and a higher percentage underwent a major surgical procedure (85.8% vs. 73.6%, p < 0.001). Among TXA recipients, 12.5% developed VTE (1.3% PT, 2.4% PE, 8.8% DVT) with 5.6% mortality. In the non-TXA group, 4.6% developed VTE (1.1% PT, 0.5% PE, 3.0% DVT) with 1.7% mortality. In analyses adjusting for patient demographic and clinical characteristics, TXA administration was not significantly associated with VTE (aHR 1.00, 95%CI: 0.69-1.46, p = 0.99) but was significantly associated with increased mortality (aHR 2.01, 95%CI: 1.46-2.77, p < 0.001). CONCLUSION TXA was not clearly identified as an independent risk factor for VTE in adjusted analyses, but the risk of VTE among trauma patients receiving TXA remains high (12.5%). This supports the judicious use of TXA in resuscitation, with consideration of early initiation of DVT prophylaxis in this high-risk group.

Abstract
BACKGROUND Patients undergoing lower extremity amputation after trauma are at high risk of venous thromboembolism. Practice variations persist regarding the optimal pharmacologic agent for venous thromboembolism prophylaxis in this patient population. We aimed to compare the efficacy of unfractionated heparin versus low-molecular-weight heparin in preventing venous thromboembolism. METHODS Using the 2013 to 2019 American College of Surgeons Pediatric Trauma Quality Improvement Program database, all trauma patients (≥18) who underwent lower limb amputation and received venous thromboembolism thromboprophylaxis in the form of unfractionated heparin or low-molecular-weight heparin were included. We excluded patients who died within 24 hours of admission or those who received no thromboprophylaxis. The primary outcome was the rate of venous thromboembolism. Multivariable logistic regression was used to evaluate the independent relationship between the type of pharmacologic prophylaxis and the risk of venous thromboembolism. RESULTS A total of 4,103 patients who underwent lower extremity amputation were identified. Patients were primarily young (median age 43 years) with blunt injuries (83%). The overall rate of venous thromboembolism was 8.6%. Most (77%) patients received low-molecular-weight heparin-based prophylaxis. Compared with patients without venous thromboembolism, the venous thromboembolism cohort had a greater injury severity score (19 vs 13, P < .001), had more patients undergoing above-the-knee amputation (48% vs 36%, P < .001), and less frequently received low-molecular-weight heparin (64% vs 78%, P < .001). Multivariable analysis showed that low-molecular-weight heparin was associated with a significantly lower venous thromboembolism rate than unfractionated heparin (odds ratio: 0.65 [0.51-0.83], P < .001). CONCLUSION Thromboprophylaxis with low-molecular-weight heparin was found to be superior to unfractionated heparin in lowering the risk of venous thromboembolism among traumatic amputees and should be the preferred pharmacologic agent in this patient population prone to venous thromboembolism.

Abstract
BACKGROUND To investigate venous thromboembolism (VTE) in patients undergoing distal cholangiocarcinoma (dCCA) surgery, we performed a single-center study to assess its prevalence, risk factors, prognosis. METHOD We studied a total of 177 patients undergoing dCCA surgery from January 2017 to April 2022. Demographic, clinical data, laboratory data (including lower extremity ultrasound findings), and outcome variables were obtained, and compared between VTE and non-VTE groups. RESULTS Of the 177 patients undergoing dCCA surgery (aged 65.2 ± 9.6 years; 108 (61.0%) male), 64 patients developed VTE after surgery. Logistic multivariate analysis showed that, age, operation procedure, TNM stage, ventilator duration and preoperative D-dimer were independent risk factors. Based on these factors, we constructed the nomogram to predict VTE after dCCA for the first time. The areas under the receiver operating curve (ROC) of the nomogram were 0.80 (95% CI: 0.72-0.88) and 0.79 (95% CI: 0.73-0.89) in the training and validation groups, respectively. Patients developed VTE had a worse prognosis by Kaplan-Meier curve analysis (p = 0.001). CONCLUSION The prevalence of VTE is high and is associated with adverse outcomes in patients undergoing dCCA surgery. We developed a nomogram assessing VTE risk, which may help clinicians to screen out people at high risk for VTE and to undertake rational preventive measures.

Abstract
Low molecular weight heparin (LMWH) is often used to prevent perioperative venous thrombosis after surgery, but aspirin is also recommended by academics. Studies were searched in electronic databases until February 24, 2023. We performed a meta-analysis to evaluate the safety and efficacy of aspirin and LMWH for venous thromboembolism (VTE) prophylaxis in patients after orthopedic surgery. The outcomes were death from any causes, deep vein thrombosis (DVT), pulmonary embolism (PE), etc. This study was registered with INPLASY, number 202320117. Six randomized controlled trials enrolled 13,851 patients with postoperative joint surgery. The risk of DVT was comparable between the two groups when aspirin was combined with mechanical devices (RR 0.61 [95% CI 0.27-1.39], I² = 62%, P = 0.24). No significant differences in all cause death, PE, wound infection, and wound complication were found between the aspirin and LMWH groups. In this meta-analysis, the mortality rate was comparable between the aspirin and LMWH groups. However, aspirin alone had a higher risk of DVT than LMWH. Based on the results of this meta-analysis, we suggest aspirin combined with mechanical devices for VTE prophylaxis in patients after orthopedic surgery.

Abstract
PURPOSE Fixed-dose and body mass index (BMI)-based enoxaparin regimens provide inadequate venous thromboembolism (VTE) prophylaxis for many trauma patients. The purpose of this study was to evaluate the effectiveness of a novel blood volume (BV)-based enoxaparin guideline vs a historical BMI-based guideline for VTE prophylaxis in trauma patients. METHODS This was a retrospective pre/post study completed at a large academic level 1 trauma center. All adult trauma patients admitted from October through December 2019 and August through October 2020 who received prophylactic enoxaparin per guideline were included. The BV dosing was as follows: patients with a BV of 3 to 4.9 L received enoxaparin 30 mg every 12 hours, those with a BV of 5 to 6.9 L received 40 mg every 12 hours, and those with a BV of ≥7 L received 60 mg every 12 hours. The primary outcome was the percentage of patients who attained a target anti-factor Xa (anti-Xa) postdosing level at the first steady-state assessment (0.2 to 0.5 IU/mL). RESULTS A total of 241 patients (99 for the BMI group and 142 for the BV group) were included. The study groups had a median age of 38 vs 42 years, a mean BMI of 27.4 vs 27.7 kg/m2, and a mean BV of 5.1 vs 5.1 L, respectively. A total of 63 patients (62.6%) in the BMI group attained target anti-Xa levels compared to 115 patients (81%) in the BV group (P = 0.008). In multivariate regression, the BV-based guideline was the only variable associated with attainment of target anti-Xa levels (adjusted odds ratio, 2.02; P = 0.01). Clinically relevant bleeding and VTE rates were similar between the groups. CONCLUSION Dosing prophylactic enoxaparin using a BV-based dosing guideline significantly increased attainment of target anti-Xa levels.

Abstract
Introduction Venous thromboembolism (VTE), particularly pulmonary embolism (PE), is the third highest cause of death in trauma patients who survive beyond the first day. Musculoskeletal surgery is associated with several complications, some of which may be life-threatening, including deep vein thrombosis (DVT) and PE. Objective This research aims to describe risk variables for VTE after upper extremity (UE) fracture at a single institution and estimate the incidence of PE following UE fracture. Methods The writers accessed the database via their respective universities using the International Standard Classification (ICD) codes. The medical files of patients aged 18 and older who sought treatment at our emergency department for an injury to their UE and also sought treatment at the orthopedics and traumatology clinic between the years 2013 and 2021 were manually scanned. The patients who applied to the Chest Diseases Clinic within 30 days after the trauma and were diagnosed with PE in the ICD code scan were included in the study. Results UE trauma was the cause of admission to the emergency department for 3,265 patients, and 21 of those patients (0.64%) were found to have PE. Fifteen of the patients were male, and six were female. The median age was 59 years (IQR 17). There were no deaths associated with PE. One of the patients had a scaphoid fracture, seven patients had a humerus fracture, five patients had a distal radius fracture, two patients had an acromioclavicular joint injury, one patient had a shoulder dislocation, one patient had a finger fracture, four patients had wrist crush injury. Three patients had diabetes mellitus. Five patients were active smokers. JAK-2 gene V617F mutation was detected in one patient. One patient was diagnosed with prostate cancer, and one had gastric cancer. One patient had a central venous catheter. Two patients were being treated for hypothyroidism. Two patients had hypertension. Conclusion According to the findings of our research, the probability of developing PE in the days following of an injury to the UE was found to be 0.64%. Patients with UE injuries who are active smokers and who also have diabetes, hypertension, hypothyroidism, cancer, coagulation disorder (JAK2 gene V617F mutation), or a central venous catheter may benefit from anticoagulant prophylaxis. This is because these patients are at a higher risk of developing dangerous blood clots.

Abstract
PURPOSE Trauma patients are at high risk of venous thromboembolism (VTE). We summarize the comparative efficacy and safety of anti-Xa-guided versus fixed dosing for low molecular weight heparin (LMWH) for the prevention of VTE in adult trauma patients. METHODS We searched Medline and Embase from inception through June 1, 2022. We included randomized controlled trials or observational studies comparing anti-Xa-guided versus fixed dosing of LMWH for thromboprophylaxis in adult trauma patients. We incorporated primary data from 2 large observational cohorts. We pooled effect estimates using a random-effects model. We assessed risk of bias using the ROBINS-I tool for observational studies and assessed certainty of findings using GRADE methodology. RESULTS We included 15 observational studies involving 10,348 patients. No randomized controlled trials were identified. determined that, compared to fixed LMWH dosing, anti-Xa-guided dosing may reduce deep vein thrombosis [adjusted odds ratio (aOR); 0.52, 95% CI: 0.40-0.69], pulmonary embolism (aOR: 0.48, 95% CI: 0.30-0.78) or any VTE (aOR: 0.54, 95% CI: 0.42-0.69), though all estimates are based on low certainty evidence. There was an uncertain effect on mortality (aOR: 1.06, 95% CI: 0.85-1.32) and bleeding events (aOR: 0.84, 95% CI: 0.50-1.39), limited by serious imprecision. We used several sensitivity and subgroup analyses to confirm the validity of our assumptions. CONCLUSION Anti-Xa-guided dosing may be more effective than fixed dosing for prevention of deep vein thrombosis, pulmonary embolism, and VTE for adult trauma patients. These promising findings justify the need for a high-quality randomized study with the potential to deliver practice changing results.

Abstract
Background: Trauma is an independent risk factor for venous thromboembolism (VTE). Due to contraindications or delay in starting pharmacological prophylaxis among trauma patients with a high risk of bleeding, the inferior vena cava (IVC) filter has been utilized as alternative prevention for pulmonary embolism (PE). Albeit, its clinical efficacy has remained uncertain. Therefore, we performed an updated systematic review and meta-analysis on the effectiveness and safety of prophylactic IVC filters in severely injured patients. Methods: Three databases (MEDLINE, EMBASE, and Cochrane) were searched from August 1, 2012, to October 27, 2021. Independent reviewers performed data extraction and quality assessment. Relative risk (RR) at 95% confidence interval (CI) pooled in a randomized meta-analysis. A parallel clinical practice guideline committee assessed the certainty of evidence using the GRADE approach. The outcomes of interest included VTE, PE, deep venous thrombosis, mortality, and IVC filter complications. Results: We included 10 controlled studies (47 140 patients), of which 3 studies (310 patients) were randomized controlled trials (RCTs) and 7 were observational studies (46 830 patients). IVC filters demonstrated no significant reduction in PE and fatal PE (RR, 0.27; 95% CI, 0.06-1.28 and RR, 0.32; 95% CI, 0.01-7.84, respectively) by pooling RCTs with low certainty. However, it demonstrated a significant reduction in the risk of PE and fatal PE (RR, 0.25; 95% CI, 0.12-0.55 and RR, 0.09; 95% CI, 0.011-0.81, respectively) by pooling observational studies with very low certainty. IVC filter did not improve mortality in both RCTs and observational studies (RR, 1.44; 95% CI, 0.86-2.43 and RR, 0.63; 95% CI, 0.3-1.31, respectively). Conclusion: In trauma patients, moderate risk reduction of PE and fatal PE was demonstrated among observational data but not RCTs. The desirable effect is not robust to outweigh the undesirable effects associated with IVC filter complications. Current evidence suggests against routinely using prophylactic IVC filters.

Abstract
INTRODUCTION Management of hemorrhage from pelvic fractures is complex and requires multidisciplinary attention. Pelvic angioembolization (AE) has become a key intervention to aid in obtaining definitive hemorrhage control. We hypothesized that pelvic AE would be associated with an increased risk of venous thromboembolism (VTE). METHODS All adults (age >16) with a severe pelvic fracture (Abbreviated Injury Scale ≥ 4) secondary to a blunt traumatic mechanism in the 2017-2019 American College of Surgeons Trauma Quality Improvement Program database were included. Patients who did not receive VTE prophylaxis during their admission were excluded. Patients who underwent pelvic AE during the first 24 h of admission were compared to those who did not using propensity score matching. Matching was performed based on patient demographics, admission physiology, comorbidities, injury severity, associated injuries, other hemorrhage control procedures, and VTE prophylaxis type, and time to initiation of VTE prophylaxis. The rates of VTE (deep vein thrombosis and pulmonary embolism) were compared between the matched groups. RESULTS Of 72,985 patients with a severe blunt pelvic fracture, 1887 (2.6%) underwent pelvic AE during the first 24 h of admission versus 71,098 (97.4%) who did not. Pelvic AE patients had a higher median Injury Severity Score and more often required other hemorrhage control procedures, with laparotomy being most common (24.7%). The median time to initiation of VTE prophylaxis in pelvic AE versus no pelvic AE patients was 60.1 h (interquartile range = 36.6-98.6) versus 27.7 h (interquartile range = 13.9-52.4), respectively. After propensity score matching, pelvic AE patients were more likely to develop VTE compared to no pelvic AE patients (11.8% versus 9.5%, P = 0.03). CONCLUSIONS Pelvic AE for control of hemorrhage from severe pelvic fractures is associated with an increased risk of in-hospital VTE. Patients who undergo pelvic AE are especially high risk for VTE and should be started as early as safely possible on VTE prophylaxis.

Abstract
PURPOSE Studies in non-trauma populations have shown that Black patients have a higher risk of venous thromboembolism (VTE) compared to other races. We sought to determine whether this association exists in trauma patients. The incidence of VTE is particularly high following severe pelvic fractures. To limit confounding factors associated with additional injuries, we examined patients with isolated blunt severe pelvic fractures. METHODS The TQIP database (2013-2017) was queried for all patients who sustained isolated blunt severe pelvic fractures (AIS ≥ 3) and received VTE prophylaxis (VTEp) with either unfractionated heparin or low molecular weight heparin. The study groups were Asian, Black, and White race as defined by TQIP. The primary outcome was differences in the rate of thromboembolic events. RESULTS A total of 9491 patients were included in the study. Of these, 232 (2.4%) were Asian, 1238 (13.0%) Black, and 8021 (84.5%) White. There was no significant difference in the distribution of pelvis AIS 3,4,5 between the groups. Black patients had a significantly higher incidence of VTE, DVT and PE compared to Asians and Whites. After adjusting for differences between the groups, Black patients had higher odds of developing pulmonary embolism (OR 1.887, 95% CI 1.101-3.232, p = 0.021) compared to White patients. CONCLUSIONS In this nationwide study of trauma patients with severe pelvic fractures, Black patients were more likely to develop pulmonary embolism compared to White patients. Further research to identify the determinants of racial disparities in trauma-related VTE is warranted, to target interventions that can improve VTE outcomes for all patients.

Abstract
BACKGROUND Clinical guidelines recommend low-molecular-weight heparin for thromboprophylaxis in patients with fractures, but trials of its effectiveness as compared with aspirin are lacking. METHODS In this pragmatic, multicenter, randomized, noninferiority trial, we enrolled patients 18 years of age or older who had a fracture of an extremity (anywhere from hip to midfoot or shoulder to wrist) that had been treated operatively or who had any pelvic or acetabular fracture. Patients were randomly assigned to receive low-molecular-weight heparin (enoxaparin) at a dose of 30 mg twice daily or aspirin at a dose of 81 mg twice daily while they were in the hospital. After hospital discharge, the patients continued to receive thromboprophylaxis according to the clinical protocols of each hospital. The primary outcome was death from any cause at 90 days. Secondary outcomes were nonfatal pulmonary embolism, deep-vein thrombosis, and bleeding complications. RESULTS A total of 12,211 patients were randomly assigned to receive aspirin (6101 patients) or low-molecular-weight heparin (6110 patients). Patients had a mean (±SD) age of 44.6±17.8 years, 0.7% had a history of venous thromboembolism, and 2.5% had a history of cancer. Patients received a mean of 8.8±10.6 in-hospital thromboprophylaxis doses and were prescribed a median 21-day supply of thromboprophylaxis at discharge. Death occurred in 47 patients (0.78%) in the aspirin group and in 45 patients (0.73%) in the low-molecular-weight-heparin group (difference, 0.05 percentage points; 96.2% confidence interval, -0.27 to 0.38; P<0.001 for a noninferiority margin of 0.75 percentage points). Deep-vein thrombosis occurred in 2.51% of patients in the aspirin group and 1.71% in the low-molecular-weight-heparin group (difference, 0.80 percentage points; 95% CI, 0.28 to 1.31). The incidence of pulmonary embolism (1.49% in each group), bleeding complications, and other serious adverse events were similar in the two groups. CONCLUSIONS In patients with extremity fractures that had been treated operatively or with any pelvic or acetabular fracture, thromboprophylaxis with aspirin was noninferior to low-molecular-weight heparin in preventing death and was associated with low incidences of deep-vein thrombosis and pulmonary embolism and low 90-day mortality.

Abstract
BACKGROUND The optimal enoxaparin dosing strategy to achieve venous thromboembolism (VTE) prophylaxis in trauma patients remains unclear. Current dosing guidelines often include weight, age, and renal function but still fail to achieve appropriate prophylactic anti-Xa levels in many patients. We hypothesized that additional patient factors influence anti-Xa response to enoxaparin in trauma patients. METHODS This is a retrospective review of patients admitted to a Level 1 trauma center for ≥4 days from July 2015 to September 2020, who received enoxaparin VTE prophylaxis per protocol (50-59 kg, 30 mg/dose; 60-99 kg, 40 mg/dose; ≥100 kg, 50 mg/dose; all doses every 12 hours) and had an appropriately timed peak anti-Xa level. Multivariate regression was performed to identify independent predictors of prophylactic anti-Xa levels (0.2-0.4 IU/mL) upon first measurement. RESULTS The cohort (N = 1,435) was 76.4% male, with a mean ± SD age of 49.9 ± 20.0 years and a mean ± SD weight of 82.5 ± 20.2 kg (males, 85.2 kg; females, 73.7 kg; p <0.001). Overall, 68.6% of patients (n = 984) had a prophylactic anti-Xa level on first assessment (69.6% of males, 65.1% of females). Males were more likely to have a subprophylactic level than females (22.1% vs. 8.0%, p <0.001), whereas females were more likely to have supraprophylactic levels than males (26.9% vs. 8.3%, p < 0.001). When controlling for creatinine clearance, anti-Xa level was independently associated with dose-to-weight ratio (odds ratio, 0.191 for 0.5 mg/kg; p < 0.001; confidence interval, 0.151-0.230) and female sex (odds ratio, 0.060; p < 0.001; confidence interval, 0.047-0.072). Weight and age were not significant when controlling for the other factors. CONCLUSION Male patients have a decreased anti-Xa response to enoxaparin when compared with female patients, leading to a greater incidence of subprophylactic anti-Xa levels in male patients at all dose-to-weight ratios. To improve the accuracy of VTE chemoprophylaxis, sex should be considered as a variable in enoxaparin dosing models. LEVEL OF EVIDENCE Therapeutic/Care Management; Level III.

Abstract
Background The permanent placement of inferior vena cava (IVC) filters may lead to numerous complications and their removal is recommended once the risk of pulmonary embolism is reduced. Removal of IVC filters by endovenous means is preferred. But failure of endovenous removal happens when recycling hooks penetrate the vein wall and filters are left in place for too long time. In these scenarios, open surgery may be effective for removal of IVC filters. We aimed to describe the surgical approach, outcomes, and 6-month follow-up of the removal of IVC filter by open surgery, after the failure of removal via the endovenous method. Methods A total of 1,285 patients with retrievable IVC filters were admitted from July 2019 to June 2021, including 1,176 (91.5%) endovenous filter removals, and 24 (1.9%) open surgical IVC filter removals after the failure by endovenous method, of whom 21 (1.6%) were followed-up and eligible for analysis of the study. Patient characteristics, filter type, filter removal rate, IVC patency rate, and complications were retrospectively analyzed. Results Twenty-one patients were left with IVC filters for 26 (10, 37) months, of which 17 (81.0%) patients had non-conical filters and 4 (19.0%) had conical filters; all 21 filters were successfully removed, with a 100% removal rate, no deaths, no serious complications, and no symptomatic pulmonary embolism. At the 3rd month follow-up after surgery and 3rd month follow-up after discontinuation of anticoagulation therapy, only 1 case (4.8%) had IVC occlusion, but without any occurrence of new lower limb deep venous thrombosis and silent pulmonary embolism. Conclusion Open surgery can be used for the removal of IVC filters after failure of removal by endovenous method or when accompanied by complications without symptoms of pulmonary embolism. Open surgical approach can be used as an adjunctive clinical intervention for the removal of such filters.

Abstract
The management of proximal tibial fractures has evolved significantly in recent years. While the main goals of treatment - stability, restoration of the mechanical axis, and smooth articular surfaces - remain the same, methods have advanced substantially. In diagnostics, technical progress in CT and MR imaging has led to a better three-dimensional understanding of the injury. Newly developed classification systems such as the three-column concept of Luo et al. and the 10-segment concept of Krause et al. take this into account. Accordingly, there is a trend towards tailored approaches for particular fracture localizations. Parallel to this development, there is increasing evidence of the advantages of arthroscopically assisted surgical procedures. This Current Concepts article reviews classifications, diagnostics, treatment options as well as complications in fractures of the proximal tibia.

Abstract
BACKGROUND The purpose of this study was to evaluate the safety and efficacy of early venous thromboembolism (VTE) chemoprophylaxis following blunt solid organ injury. METHODS A retrospective review of patients was performed for patients with blunt solid organ injury between 2009-2019. Enoxaparin was initiated when patients had <1g/dl Hemoglobin decline over a 24 h period. These patients were then categorized by initiation: ≤48 h and >48 h. RESULTS There were 653 patients: 328 (50.2%) <48 h and 325 (49.8%) ≥48 h. Twenty-nine (4.4%) developed VTE. Patients in ≥48 h group suffered more frequent VTE events (6.5% vs 2.4%, p = 0.021). Non-operative failure occurred in 6 patients (1.9%) in ≥48 h group, and 5 patients (1.5%) < 48 h group. Blood transfusion following chemophrophylaxis initiation was required in 69 (21.3%) in ≥48 h group, and 46 (14.0%) in < 48 h group, occurring similarly between groups (p=0.021). CONCLUSION Stable hemoglobin in the first 24 h is an efficacious, objective measure that allows early initiation of VTE chemoprophylaxis in solid organ injury. This practice is associated with earlier initiation of and fewer VTE events.

Abstract
BACKGROUND Posttraumatic venous thromboembolism (VTE) remains prevalent in severely injured patients despite chemoprophylaxis. Importantly, although platelets are central to thrombosis, they are not routinely targeted in prevention of posttraumatic VTE. Furthermore, platelets from injured patients show ex vivo evidence of increased activation yet impaired aggregation, consistent with functional exhaustion. However, the relationship of this platelet functional phenotype with development of posttraumatic VTE is unknown. We hypothesized that, following injury, impaired ex vivo platelet aggregation (PA) is associated with the development of posttraumatic VTE. METHODS We performed a secondary analysis of 133 severely injured patients from a prospective observational study investigating coagulation and inflammation (2011-2019). Platelet aggregation in response to stimulation with adenosine diphosphate (ADP), collagen, and thrombin was measured at presentation (preresuscitation) and 24 hours (postresuscitation). Viscoelastic clot strength and lysis were measured in parallel by thromboelastography. Multivariable regression examined relationships between PA at presentation, 24 hours, and the change (δ) in PA between presentation and 24 hours with development of VTE. RESULTS The 133 patients were severely injured (median Injury Severity Score, 25), and 14% developed VTE (all >48 hours after admission). At presentation, platelet count and PA were not significantly different between those with and without incident VTE. However, at 24 hours, those who subsequently developed VTE had significantly lower platelet counts (126 × 10 9 /L vs. 164 × 10 9 /L, p = 0.01) and lower PA in response to ADP ( p < 0.05), collagen ( p < 0.05), and thrombin ( p = 0.06). Importantly, the magnitude of decrease in PA (δ) from presentation to 24 hours was independently associated with development of VTE (adjusted odds ratios per 10 aggregation unit decrease: δ-ADP, 1.31 [ p = 0.03]; δ-collagen, 1.36 [ p = 0.01]; δ-thrombin, 1.41 [ p < 0.01]). CONCLUSION Severely injured patients with decreasing ex vivo measures of PA despite resuscitation have an increased risk of developing VTE. This may have implications for predicting development of VTE and for studying platelet targeted chemoprophylaxis regimens. LEVEL OF EVIDENCE Prognostic/Epidemiological; Level III.

Clinical Characteristics and Risk Factors for Early versus Late Pulmonary Embolism in Trauma Patients: A Retrospective, Observational Study. Int J Gen Med 2022; 15:7867-7878.

Abstract
Background We sought to evaluate the clinical characteristics and risk factors for early versus late pulmonary embolism (PE) in trauma patients. Methods This was a retrospective analysis of injured patients who presented with a confirmed PE between 2013 and 2019. Data were analysed and compared for patients with early PE (≤4 days) versus late PE (>4 days post-trauma). Results The study included 82 consecutive trauma patients with confirmed diagnosis of PE. The mean age of patients was 42.3 ± 16.2 years. The majority were males (79.3%) and the median time from injury to PE was 10 days. Of the PE cases, 24 (29.3%) had early PE, while 58 (70.7%) had late PE. The early PE group had higher rates of surgical intervention within 24 hours of admission than the late PE group (p = 0.001). Also, the rate of sub-segmental thrombi was significantly higher in the early PE group (p = 0.01). The late PE group sustained more moderate-to-severe injuries ie, GCS ED <13 (p = 0.03) and the median time from injury to PE diagnosis was 15 days (p = 0.001). After adjusting for the potential covariates, surgery within 24 hours of admission [adjusted odds ratio 37.58 (95% confidence interval 3.393-416.20), p = 0.003] was found to be significant independent predictor of early PE in trauma patients. Conclusion One-third of post-trauma PEs occurs early after trauma and the surgical intervention within the first 24 hours of admission is a major risk factor. A prospective study is needed to develop an objective risk assessment for the prevention and detection of early and late PE post-trauma.

Abstract
Background In 2017, the World Society of Emergency Surgery published its guidelines for the management of adult and pediatric patients with splenic trauma. Several issues regarding the follow-up of patients with splenic injuries treated with NOM remained unsolved.
Methods Using a modified Delphi method, we sought to explore ongoing areas of controversy in the NOM of splenic trauma and reach a consensus among a group of 48 international experts from five continents (Africa, Europe, Asia, Oceania, America) concerning optimal follow-up strategies in patients with splenic injuries treated with NOM.
Results Consensus was reached on eleven clinical research questions and 28 recommendations with an agreement rate ≥ 80%. Mobilization after 24 h in low-grade splenic trauma patients (WSES Class I, AAST Grades I–II) was suggested, while in patients with high-grade splenic injuries (WSES Classes II–III, AAST Grades III–V), if no other contraindications to early mobilization exist, safe mobilization of the patient when three successive hemoglobins 8 h apart after the first are within 10% of each other was considered safe according to the panel. The panel suggests adult patients to be admitted to hospital for 1 day (for low-grade splenic injuries—WSES Class I, AAST Grades I–II) to 3 days (for high-grade splenic injuries—WSES Classes II–III, AAST Grades III–V), with those with high-grade injuries requiring admission to a monitored setting. In the absence of specific complications, the panel suggests DVT and VTE prophylaxis with LMWH to be started within 48–72 h from hospital admission. The panel suggests splenic artery embolization (SAE) as the first-line intervention in patients with hemodynamic stability and arterial blush on CT scan, irrespective of injury grade. Regarding patients with WSES Class II blunt splenic injuries (AAST Grade III) without contrast extravasation, a low threshold for SAE has been suggested in the presence of risk factors for NOM failure. The panel also suggested angiography and eventual SAE in all hemodynamically stable adult patients with WSES Class III injuries (AAST Grades IV–V), even in the absence of CT blush, especially when concomitant surgery that requires change of position is needed. Follow-up imaging with contrast-enhanced ultrasound/CT scan in 48–72 h post-admission of trauma in splenic injuries WSES Class II (AAST Grade III) or higher treated with NOM was considered the best strategy for timely detection of vascular complications. Conclusion This consensus document could help guide future prospective studies aiming at validating the suggested strategies through the implementation of prospective trauma databases and the subsequent production of internationally endorsed guidelines on the issue.

Abstract
Purpose: The aim of this study was to investigate the epidemiology of trauma inpatients with venous thromboembolism (VTE) symptoms diagnosed using computed tomographic angiography (CTA) in KoreaMethods: In total, 7,634 patients admitted to the emergency department of Gachon University Gil Medical Center, a tertiary hospital, and hospitalized between July 1, 2018 and December 31, 2020 were registered for this study. Of these patients, 278 patients who underwent CTA were enrolled in our study. Results: VTE was found in 120 of the 7,634 patients (1.57%), and the positive diagnosis rate of the 278 patients who underwent CTA was 43.2% (120 of 278). The incidence of VTE was statistically significantly higher among those with severe head and neck injuries (Abbreviated Injury Scale, 3–5) than among those with nonsevere head and neck injuries (Abbreviated Injury Scale, 0–2; P=0.038). In a subgroup analysis, the severe and nonsevere head and neck injury groups showed statistically significant differences in known independent risk factors for VTE. In logistic regression analysis, the adjusted odds ratio of severe head and neck injury (Abbreviated Injury Scale, 3–5) for VTE was 1.891 (95% confidence interval, 1.043–3.430). Conclusions: Trauma patients with severe head and neck injuries are more susceptible to VTE than those with nonsevere head and neck injuries. Thus, physicians must consider CTA as a priority for the diagnosis of VTE in trauma patients with severe head and neck injuries who show VTE-associated symptoms.

Abstract
INTRODUCTION Recent studies have demonstrated a hypercoagulable thromboelastrogram (TEG) in female trauma patients compared with males, conferring a possible survival advantage. We hypothesized that TEG profiles would reveal a relative hypercoagulable state in female compared with male trauma patients. METHODS A prospective review was conducted on all adult trauma patients admitted to the trauma service at an American College of Surgeons-verified level I trauma center from December 2019 to June 2021 who, per our institutional protocol, received a thrombelastotgraphy on their initial arrival to the trauma center if classified as a level I or II trauma activation. The thromboelastography values of male and female trauma patients were compared as the primary outcome variables of interest. The secondary outcomes investigated were hospital length of stay, surgical interventions, and ventilatory requirement. RESULTS A total of 1369 patients met inclusion criteria, with 878 (64.1%) male and 491 (35.9%) female. Female patients had a higher median alpha angle (74.8 versus 72.6°, P < 0.001), maximum amplitude (69.3 versus 66.2 mm, P < 0.001), and shorter median K time (1.0 versus 1.2 s, P < 0.001). Female patients had a shorter hospital length of stay (4 versus 5 d, P < 0.001), had a lower rate of surgical intervention (14.6% versus 25.5%, P < 0.001), and had lower rates of mechanical ventilation (19.3% versus 39.5%, P < 0.001). CONCLUSIONS Female trauma patients were found to have hypercoagulable indices on TEG at the time of initial trauma evaluation compared with males. Intrinsic differences in sex coagulation profiles should be further investigated to optimize modern resuscitation strategies.

Abstract
BACKGROUND Venous thromboembolism (VTE) in severely injured patients with severe traumatic brain injury (TBI) is a risk during the clinical course. Data on the safety of an early initiation of pharmacological VTE prophylaxis in severely injured patients with concomitant severe TBI is sparse. METHODS Admissions to our level-1-trauma center between January 2015 and December 2018 were screened. Patients suffering from severe TBI (Abbreviated Injury Scale (AIS) of the head ≥3) and at least one further AIS ≥ 3 in any other body region were included. Demographic data, thromboembolic events, and progression of the intracranial hemorrhage were extracted from the patient's charts. According to the first application of pharmacological thromboprophylaxis (VTEp), patients were categorized either to the early, the late (later than 24 h) or the no therapy group. RESULTS In 79 patients (early: n = 35, late: n = 29, no therapy: n = 15) the Injury Severity Score (ISS) was 36.7 ± 12.7 points (AIShead 4.1 ± 0.8). No differences were found regarding the progression of the intracranial hemorrhage after initiation of the VTE prophylaxis (adj. p = 0.8). The VTE rate was low (n = 1, 1.6%). CONCLUSION In severely injured patients with severe TBI, the early administration of pharmacological thromboprophylaxis did not result in a higher rate of intracranial hematoma progression.

Abstract
BACKGROUND Isolated distal deep vein thromboses (IDDVT) are common complications of trauma inpatient admission, however their management is controversial. We aimed to analyse outcomes in patients admitted to a level three tertiary referral centre who received therapeutic anticoagulation compared to those that did not. We hypothesised that therapeutic anticoagulation would be safe and effective in trauma inpatients who develop IDDVT. METHODS We performed a review of the electronic case notes of all patients with venous thromboembolism listed as a complication whilst admitted as an inpatient under the trauma unit at a tertiary institution over a 4-year period, from October 2014 to October 2018. Demographic data was collected, as well as data regarding management, major bleeding and progression of thrombosis to proximal DVT or PE. RESULTS 91 IDDVT in trauma inpatients were identified. 33 patients received therapeutic anticoagulation within seven days of their diagnosis. No major bleeding was observed in this group, while one episode of thrombus progression was observed. 58 patients were not given therapeutic anticoagulation within seven days of IDDVT diagnosis. There were seven episodes of thrombus progression in this group on median day 5 post diagnosis, while no major bleeding was observed. CONCLUSION Only approximately 1/3rd of patients with IDDVT after trauma received therapeutic anticoagulation, and in these selected cases it appears safe. Those who did not receive therapeutic anticoagulation had a significant rate of thrombosis extension into the proximal system and pulmonary embolus. Further studies on correctly identifying who can be safely anticoagulated are required and for those who cannot be, these data show more aggressive surveillance and prophylaxis needs to be considered.

Trauma Surg Acute Care Open 2022; 7:e000923. [PMID: 35813557 PMCID: PMC9214426 DOI: 10.1136/tsaco-2022-000923] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2022] [Accepted: 05/20/2022] [Indexed: 11/07/2022] Open
Abstract
Background Venous thromboembolism (VTE) after an inferior vena cava (IVC) injury is a devastating complication. Current practice involves variable use of anticoagulation and antiplatelet (AC/AP) agents. We hypothesized that AC/AP can reduce the incidence of VTE and that delayed institution of AC/AP is associated with increased VTE events. Methods We retrospectively reviewed IVC injuries cared for at a large urban adult academic level 1 trauma center between January 1, 2008 and December 31, 2020, surviving 72 hours. Patient demographics, injury mechanism, surgical repair, type and timing of AC, and type and timing of VTE events were characterized. Postoperative AC status during hospital course before an acute VTE event was delineated by grouping patients into four categories: full, prophylactic, prophylactic with concomitant AP, and none. The primary outcome was the incidence of an acute VTE event. IVC ligation was excluded from analysis. Results Of the 76 patients sustaining an IVC injury, 26 were included. The incidence of a new deep vein thrombosis distal to the IVC injury and a new pulmonary embolism was 31% and 15%, respectively. The median onset of VTE was 5 days (IQR 1–11). Four received full AC, 10 received prophylactic AC with concomitant AP, 8 received prophylactic AC, and 4 received no AC/AP. New VTE events occurred in 0.0% of full, in 30.0% of prophylactic with concomitant AP, in 50.0% of prophylactic, and in 50.0% without AC/AP. There was no difference in baseline demographics, injury mechanisms, surgical interventions, and bleeding complications. Discussion This is the first study to suggest that delay and degree of antithrombotic initiation in an IVC-injured patient may be associated with an increase in VTE events. Consideration of therapy initiation should be performed on hemostatic stabilization. Future studies are necessary to characterize the optimal dosing and temporal timing of these therapies. Level of evidence Therapeutic, level 3.

World Neurosurg 2022; 164:e1251-e1261. [PMID: 35691523 DOI: 10.1016/j.wneu.2022.06.008] [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: 03/26/2022] [Revised: 06/01/2022] [Accepted: 06/02/2022] [Indexed: 10/18/2022]
Abstract
BACKGROUND Both unfractionated heparin (UH) and low-molecular-weight heparin (LMWH) are routinely used prophylactically after traumatic brain injury (TBI) to prevent deep vein thrombosis (DVT). Their comparative risk for development or worsening of intracranial hemorrhage necessitating cranial decompression is unclear. Furthermore, the absence of a specific antidote for LMWH may lead to UH being used more often for high-risk patients. This study aims to compare the incidence of delayed cranial decompression occurring after initiation of prophylactic UH versus LMWH using the National Trauma Data Bank. METHODS Cranial decompression procedures included craniotomy and craniectomy. Multiple imputation was used for missing data. Propensity score matching was used to account for selection bias between UH and LMWH. The 1:1 matched groups were compared using logistic regression for the primary outcome of postprophylaxis cranial decompression. RESULTS A total of 218,594 patients with TBI were included, with 61,998 (28.3%) receiving UH and 156,596 (71.7%) receiving LMWH as DVT prophylaxis. The UH group had higher patient age, body mass index, comorbidity rates, Injury Severity Score, and worse motor Glasgow Coma Scale score. After the UH and LMWH groups were matched for these factors, logistic regression showed lower rates of postprophylaxis cranial decompression for the LMWH group (odds ratio, 0.13; 95% confidence interval, 0.11-0.16; P < 0.001). CONCLUSIONS Despite the absence of a specific antidote, LMWH was associated with lower rates of need for post-DVT-prophylaxis in craniotomy/craniectomy. This finding questions the notion of UH being safer for patients with TBI because it can be readily reversed. Randomized studies are needed to elucidate causality.
