Abstract
BACKGROUND High-risk pulmonary embolism (PE) is a complex, life-threatening condition, and emergency clinicians must be ready to resuscitate and rapidly pursue primary reperfusion therapy. The first-line reperfusion therapy for patients with high-risk PE is systemic thrombolytics (ST). Despite consensus guidelines, only a fraction of eligible patients receive ST for high-risk PE. OBJECTIVE This review provides emergency clinicians with a comprehensive overview of the current evidence regarding the management of high-risk PE with an emphasis on ST and other reperfusion therapies to address the gap between practice and guideline recommendations. DISCUSSION High-risk PE is defined as PE that causes hemodynamic instability. The high mortality rate and dynamic pathophysiology of high-risk PE make it challenging to manage. Initial stabilization of the decompensating patient includes vasopressor administration and supplemental oxygen or high-flow nasal cannula. Primary reperfusion therapy should be pursued for those with high-risk PE, and consensus guidelines recommend the use of ST for high-risk PE based on studies demonstrating benefit. Other options for reperfusion include surgical embolectomy and catheter directed interventions. CONCLUSIONS Emergency clinicians must possess an understanding of high-risk PE including the clinical assessment, pathophysiology, management of hemodynamic instability and respiratory failure, and primary reperfusion therapies.

Barros PAL, Castro DJ, Goldman RE, Kwong M. Incidental deep venous thrombosis diagnosed on lower extremity computed tomography is a rare but clinically impactful finding. J Vasc Surg Venous Lymphat Disord 2024; 12:101858. [PMID: 38452896 DOI: 10.1016/j.jvsv.2024.101858] [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: 11/14/2023] [Revised: 01/18/2024] [Accepted: 01/29/2024] [Indexed: 03/09/2024]
Abstract
BACKGROUND In the setting of a known thrombotic event, computed tomography (CT) studies provide reasonable sensitivity for the diagnosis of deep venous thrombosis (DVT). However, the incidence and accuracy of a DVT diagnosis on CT studies not targeted for the detection of DVT are not well described. In addition, the clinical impact of DVTs incidentally identified on CT is unknown. METHODS In this single-institution retrospective study, we queried all contrasted CT studies of the lower extremities performed over a 10-year period. Regular expressions applied to the radiology reports associated with the CT studies identified studies with positive findings associated with DVT. These selected reports were then manually reviewed to confirm the presence of a DVT. Patient demographics and relevant medical and surgical history were obtained through a chart review. Follow-up information was obtained for 1 year after the incident CT and included treatment course, additional imaging, and adverse events. An incidental DVT was one identified in a patient in whom the DVT was not noted in a prior study and for whom the study indication did not include concern for DVT or pulmonary embolism. RESULTS Of 16,637 lower extremity contrasted CT studies queried, 37 study reports identified a DVT. However, only 13 patients had a finding of an incidental DVT (10-year incidence of 0.08%). Among these 13 patients, 11 underwent additional imaging, including 9 who had a subsequent venous duplex and 2 who had subsequent CT studies. Among those with a subsequent duplex, DVT was not identified in eight cases, whereas in one case, DVT was confirmed. Among those with subsequent CT studies, DVT was not identified in one case and was confirmed in one case. Of the 13 patients with incidental DVTs, 3 were initiated on anticoagulation based on their initial CT findings alone. Among these, two did not experience any complications from their DVT or anticoagulation regimen. One did experience major bleeding complications, requiring additional procedures. CONCLUSIONS Incidental DVTs are a rare finding in lower extremity CT studies, noted to occur in only 0.08% of studies. Most patients with incidental DVTs receive additional imaging, with negative findings in 80% of cases. This study identified that 23% of patients were initiated on anticoagulation due to the CT findings, with a 33% rate of significant complications. Currently, a CT venogram is not recommended as a first-line modality for the diagnosis of DVT. However, there is no guidance regarding the need for repeat imaging in patients with incidentally diagnosed lower extremity DVTs identified on CT. Additional study is needed to provide evidence for guideline development.

Abstract
Despite the end of the pandemic, coronavirus disease 2019 (COVID-19) remains a major public health concern. The first waves of the virus led to a better understanding of its pathogenesis, highlighting the fact that there is a specific pulmonary vascular disorder. Indeed, COVID-19 may predispose patients to thrombotic disease in both venous and arterial circulation, and many cases of severe acute pulmonary embolism have been reported. The demonstrated presence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) within the endothelial cells suggests that direct viral effects, in addition to indirect effects of perivascular inflammation and coagulopathy, may contribute to pulmonary vasculopathy in COVID-19. In this review, we discuss the pathological mechanisms leading to pulmonary vascular damage during acute infection, which appear to be mainly related to thromboembolic events, an impaired coagulation cascade, micro- and macrovascular thrombosis, endotheliitis and hypoxic pulmonary vasoconstriction. As many patients develop post-COVID symptoms, including dyspnea, we also discuss the hypothesis of pulmonary vascular damage and pulmonary hypertension as a sequela of the infection, which may be involved in the pathophysiology of long COVID.

Abstract
We analyzed chemoport insertion procedures to evaluate infectious morbidity and factors causing infection. This single-center retrospective study included 1690 cases of chemoport implantation between January 2017 and December 2020. Overall, chemoports were inserted in 1582 patients. The average duration of chemoport use was 481 days (range 1-1794, median 309). Infections occurred in 80 cases (4.7%), with 0.098 per 1000 catheter-days. Among the 80 cases in which chemoports were removed because of suspected infection, bacteria were identified in 48 (60%). Significantly more cases of left internal jugular vein punctures were noted in the infected group (15 [18.8%] vs. 147 [9.1%]; p = 0.004). Pulmonary embolism was significantly different between the infection groups (3 [3.8%] vs. 19 (1.2%), p = 0.048). The hazard ratio was 2.259 (95% confidence interval [CI] 1.288-3.962) for the left internal jugular vein, 3.393 (95% CI 1.069-10.765) for pulmonary embolism, and 0.488 (95% CI 0.244-0.977) for chronic obstructive pulmonary disease. Using the right internal jugular vein rather than the left internal jugular vein when performing chemoport insertion might reduce subsequent infections.

Lan X, Dong FY, Duan JJ. Successful Treatment Strategy for Duplicate Inferior Vena Cava and Deep Venous Thrombosis: Filter Placement and Thrombolysis Approach. AMERICAN JOURNAL OF CASE REPORTS 2024; 25:e942578. [PMID: 38630648 PMCID: PMC11034388 DOI: 10.12659/ajcr.942578] [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: 09/16/2023] [Revised: 03/05/2024] [Accepted: 02/26/2024] [Indexed: 04/19/2024]
Abstract
BACKGROUND Duplicate inferior vena cava (IVC) accompanied by deep venous thrombosis is rare. The optimal treatment plan is determined according to the results of imaging, including venography. In this report, we present a case of successful treatment of a patient with duplicate IVC and deep venous thrombosis (DVT). CASE REPORT An 84-year-old man with history of hypertension was admitted to the hospital because of 4 days of moderate left lower-limb edema. A thorough examination led to the diagnosis of the DVT. The duplicate IVC was discovered during venography. As the blood from the left common iliac vein mainly flowed to the left IVC, and there were no other communicating branches before the convergence of the left and right IVCs, which was located above the 1st lumbar vertebrae body near the junction of the hepatic vein and the IVC, the strategy of placing only 1 filter in the left inferior vena cava were chosen, rather than placing 1 filter above the confluence of bilateral IVC, or placing a filter in each IVC below the level of renal veins on each side. Following that, the DVT was safely treated with thrombolysis and aspiration without the risk of pulmonary embolism. CONCLUSIONS This case report presented the complete evaluation and management of a patient with lower-limb DVT accompanied by the malformation of duplicate IVC. The filter placement strategy with duplicate IVC in the literature was summarized. We concluded that even in emergency situations, with comprehensive consideration, it is possible to perform endovascular intervention successfully and achieve satisfactory treatment results.

Predictive factors of clot propagation in patients with superficial venous thrombosis towards deep venous thrombosis and pulmonary embolism: a systematic review and meta-analysis. BMJ Open 2024; 14:e074818.

Abstract
OBJECTIVE A subset of patients with superficial venous thrombosis (SVT) experiences clot propagation towards deep venous thrombosis (DVT) and/or pulmonary embolism (PE). The aim of this systematic review is to identify all clinically relevant cross-sectional and prognostic factors for predicting thrombotic complications in patients with SVT. DESIGN Systematic review. DATA SOURCES PubMed/MEDLINE and Embase were systematically searched until 3 March 2023. ELIGIBILITY CRITERIA Original research studies with patients with SVT, DVT and/or PE as the outcome and presenting cross-sectional or prognostic predictive factors. DATA EXTRACTION AND SYNTHESIS OF RESULTS The CHecklist for critical Appraisal and data extraction for systematic Reviews of prediction Modelling (CHARMS) checklist for prognostic factor studies was used for systematic extraction of study characteristics. Per identified predictive factor, relevant estimates of univariable and multivariable predictor-outcome associations were extracted, such as ORs and HRs. Estimates of association for the most frequently reported predictors were summarised in forest plots, and meta-analyses with heterogeneity were presented. The Quality in Prognosis Studies (QUIPS) tool was used for risk of bias assessment and Grading of Recommendations, Assessment, Development and Evaluations (GRADE) for assessing the certainty of evidence. RESULTS Twenty-two studies were included (n=10 111 patients). The most reported predictive factors were high age, male sex, history of venous thromboembolism (VTE), absence of varicose veins and cancer. Pooled effect estimates were heterogenous and ranged from OR 3.12 (95% CI 1.75 to 5.59) for the cross-sectional predictor cancer to OR 0.92 (95% CI 0.56 to 1.53) for the prognostic predictor high age. The level of evidence was rated very low to low. Most studies were scored high or moderate risk of bias. CONCLUSIONS Although the pooled estimates of the predictors high age, male sex, history of VTE, cancer and absence of varicose veins showed predictive potential in isolation, variability in study designs, lack of multivariable adjustment and high risk of bias prevent firm conclusions. High-quality, multivariable studies are necessary to be able to identify individual SVT risk profiles. PROSPERO REGISTRATION NUMBER CRD42021262819.

Abstract
BACKGROUND Venous thrombosis (VT) after esophagectomy for esophageal cancer is an important complication, potentially leading to pulmonary embolism. However, there are few available information about the risk for the postsurgical VT. METHODS This study included 271 patients who underwent esophagectomy for esophageal cancer between 2006 and 2019. Contrast-enhanced computed tomography (CT) was performed for all patients on the seventh postoperative day to survey complications, including VT. RESULTS VT was radiologically visualized in 48 patients (17.7%), 8 of whom (16.7%) had pulmonary embolism. The thrombus disappeared in 42 patients, the thrombus size was unchanged in 5 patients, and 1 patient died. Multivariate analysis was performed on factors clinically considered to have a significant influence on thrombus formation. The analysis showed that CVC insertion via the femoral vein (odds ratio, 7.67; 95% CI, 2.64-22.27; P < 0.001), retrosternal reconstruction route (odds ratio, 3.94; 95% CI, 1.90-8.17; P < 0.001) and intraoperative fluid balance < 5 ml/kg/hr (odds ratio, 0.38; 95% CI, 0.17-0.85; P = 0.019) were independently related to VT. CONCLUSIONS Intraoperative fluid balance < 5 ml/kg/hr, along with CVC insertion via the femoral vein and retrosternal reconstruction may be potential risk factors for VT after esophagectomy.

Abstract
Patients with chronic kidney disease are already at an increased risk for pulmonary embolism, since loss of renal function rendered a procoagulant state. Further, malignant tumor is a well-established risk factor for pulmonary thromboembolism. Alternatively, occlusion of the pulmonary vasculature by tumor cells per se and associated thrombi may mimic thromboembolic disease. By comparison, however, report of pulmonary tumor embolism (PTE) in patients on maintenance hemodialysis (MHD) is exceedingly rare. A less vigilant clinician may have otherwise treated this situation as fluid overload or thromboembolic disorder. We herein described in an MHD patient such an unusual case of PTE, which was diagnosed by contrast-enhanced CT and PET/CT. As such, our work may expand the knowledge reserve of dialysis staffs about this rare complication of malignancy.

Dust particulate matter increases pulmonary embolism onset: A nationwide time-stratified case-crossover study in China. ENVIRONMENT INTERNATIONAL 2024; 186:108586.

Abstract
BACKGROUND Particulate matter (PM) has been found to elevate the risk of pulmonary embolism (PE) onset. Among the contributors to PM, dust PM stands as the second natural source, and its emissions are escalating due to climate change. Despite this, information on the effect of dust PM on PE onset is scarce. Hence, this study aims to investigate the impacts of dust PM10, dust PM2.5-10, and dust PM2.5 on PE onset. METHODS A nationwide time-stratified case-crossover study was conducted between 2015 and 2020, using data from 18,616 PE onset cases across 1,921 hospitals in China. The analysis employed a conditional logistic regression model to quantify the associations between dust PM10, dust PM2.5-10, and dust PM2.5 and PE onset. Furthermore, the study explored the time-distributed lag pattern of the effect of dust PM on PE development. Stratified analyses were performed based on sex, age, region, and season. RESULTS Dust PM10, dust PM2.5-10, and dust PM2.5 exhibited significant health effects on PE onset, particularly concerning exposure on the same day. The peak estimates were observed at lag 01 day, with the odds ratio being 1.011 [95 % confidence interval (CI): 1.003, 1.019], 1.014 (95 % CI: 1.003, 1.026), and 1.039 (95 % CI: 1.011, 1.068), for a 10 μg/m3 increase in the concentration of dust PM10, dust PM2.5-10, and dust PM2.5, respectively. In addition, the study identified a higher risk of PE onset associated with dust PM exposure during the warm season than that in cool season, particularly for dust PM2.5. CONCLUSIONS The findings from this study suggest that short-term exposure to dust PM, particularly dust PM2.5, may trigger PE onset, posing a significant health threat. Implementing measures to mitigate dust PM emissions and protect patients with PE from dust PM exposure is imperative.

Abstract
INTRODUCTION Inferior vena cava (IVC) filters act in preventing pulmonary embolisms (PE). Various complications have been reported with their use. However, a credible urological complication rate, filter characteristics, and clinical presentation has yet to be summarized. Thus, we reported these complications in the form of a systematic review. EVIDENCE ACQUISITION A search strategy was designed using PubMed, MEDLINE, and EMBASE on February 10th, 2022. The design of this search strategy did not include any language restrictions. The key words (and wildcard terms) used in the search strategy were urolog*, ureter*, bladder, kidney coupled with filter, inferior vena cava, and cava*. Inclusion criteria were: patients older than 18, with previous IVC filter placement, and urologic complication reported. Exclusion criteria were: patients younger than 18, no IVC filter placement, and no urologic complication reported. Other case series and reviews were excluded to avoid patient duplication. EVIDENCE SYNTHESIS Thirty-five articles were selected for full-text screening. Thirty-seven patient cases were reviewed, and the median age was 53 (range: 21-92 years old). Abdominal and or flank pain was reported in 16 (43%) patients, hematuria was seen in eight (22%) and two (5%) patients died due to acute renal failure resulting from the urologic complications of the IVC filter. Indications for IVC filter placement were recurrent pulmonary embolism (PE), contraindication to or noncompliance with anticoagulant therapy. The IVC filters were infrarenal in 29 (78.4%) patients, suprarenal in five (13.5%) patients, not reported in two patients, and misplaced into the right ovarian vein in one patient. Three or more imaging modalities were obtained in 19 patients (51%) for planning. IVC filter removal was not performed in 17 (45.9%) patients, endovascular retrieval occurred in nine (24.3%) patients, and open removal was performed in seven (18.9%) patients, and tissue interposition was performed in two (5.4%) patients. One patient did not have the management reported. CONCLUSIONS Urological complications caused by IVC filters although rare, are likely underreported, require extensive workup, and pose surgical challenges. Due to their complex management, filter retrieval should be planned for as soon as feasible, and plans should be made as early as during the IVC filter implant. For those that do develop complications, clinical judgement must be exercised in management, and open surgical, endovascular or even conservative management strategies can be viable options and should be discussed in a multidisciplinary setting.

Abstract
BACKGROUND While accepted indications for the use of inferior vena cava filter (IVCF) in patients with a venous thromboembolism (VTE) have remained stable, their use continues to be frequent. Retrieval rates are still low, being particularly notable in the population with cancer. This study aims to review the rate of adherence to guidelines recommendation and to compare retrieval rates and complications in both cancer and non-cancer patients. METHODS A retrospective study was performed including 185 patients in whom an IVCF was placed in Hospital Clinic of Barcelona. Baseline characteristics, clinical outcomes, and IVCF-related outcomes were analyzed. A strongly recommended indication (SRI) was considered if it was included in all the revised clinical guidelines and non-strongly if it was included in only some. RESULTS Overall, 47 % of the patients had a SRI, without differences between groups. IVCF placement after 29 days from the VTE event was more frequent in the cancer group (46.1 vs. 17.7 %). Patients with cancer (48.1 % of the cohort) were older, with higher co-morbidity and bleeding risk. Anticoagulation resumption (75.3 % vs. 92.7 %) and IVCF retrieval (50.6 % vs. 66.7 %) were significantly less frequent in cancer patients. No significant differences were found regarding IVCF-related complications, hemorrhagic events and VTE recurrence. CONCLUSIONS SRI of IVCF placement was found in less than half of the patients. Cancer patients had higher rates of IVCF placement without indication and lower anticoagulation resumption and IVCF retrieval ratios, despite complications were similar in both groups.

Abstract
Hereditary protein C deficiency is a chromosomal genetic disease caused by mutations in the protein C gene,which can lead to venous thrombosis and is mostly related to mutations in exons 4-9 and intron 8.Fatal pulmonary embolism caused by mutations in the protein C gene is rare,and the treatment faces great challenges.This article reports a case of fatal pulmonary embolism caused by a frameshift mutation in exon 8 of the protein C gene and summarizes the treatment experience of combining extracorporeal membrane oxygenation (for respiratory and circulatory support) with interventional thrombectomy,providing a basis for the diagnosis and treatment of this disease.

Abstract
BACKGROUND Pulmonary embolism (PE) in critically ill patients with acute respiratory distress syndrome (ARDS) caused by COVID-19 is a major complication which might impact survival. We aimed to determine the prevalence of PE and assess its impact of PE on clinical outcomes in intubated patients with ARDS due to COVID-19. METHODS All intubated patients with ARDS due to COVID-19 admitted to the intensive care unit (ICU) of Geneva University Hospitals between March 9, 2020, and May 31, 2022, were included. A retrospective analysis was conducted on the occurrence of PE and its association with clinical outcomes. The primary outcome was ventilator-free days during the first 28 days after ICU admission. Linear regressions were performed to investigate the association between PE and outcomes. RESULTS Among the 370 intubated patients with ARDS related to COVID-19, 58 (15.7%) presented with PE. Patients with PE had significantly fewer ventilator-free days than patients without PE (median (IQR) of 3 (0-11) days versus 12 (0-19) days; p < 0.001). Mortality did not differ significantly between groups (12/58 [20.7%] of patients with PE versus 71/312 [22.8%] of patients without PE; p = 0.72). Duration of IMV, and ICU and hospital LOS were significantly longer among patients with PE. The need for ECMO support was similar among both groups. CONCLUSIONS The occurrence of PE in patients with ARDS due to COVID-19 had a significant impact on clinical outcomes. They had fewer ventilator-free days, longer duration of IMV, and longer ICU and hospital lengths of stay. However, pulmonary embolism was not associated with higher mortality. ETHICS APPROVAL Ethical committee of Geneva (BASEC #: 2020-00917).

Abstract
BACKGROUND Our study aimed to describe the clinical, paraclinical, therapeutic and outcomes of patients with venous thromboembolic event (VTE) associated with cancer in the context of limited resources. MATERIALS AND METHODS This was a descriptive cross-sectional study over a period of six years from March 1, 2016 to March 31, 2022, in the cardiology department and the oncology unit of the Sylvanus Olympio Teaching Hospital of Lome. Our study examined medical records of patients who were at least 18 years old and had venous thromboembolic disease and cancer that was histologically confirmed. This study did not include records that were incomplete or records from patients with coronavirus disease. RESULTS Our study included 87 patients with average age of 56.36±15.26 years. The discovery of VTE occurred incidentally in 28.74%. Venous thrombosis was isolated in 68.96% and proximal in 95%. Pulmonary embolism was bilateral in 77.77%. Gynaecological and urological cancers were found in 33.33% and 32.19% respectively. Adenocarcinoma was the histological type of cancer found in 47.13%. Cancers were at a very advanced stage in 74.71%. Treatment with antivitamin K was prescribed in 12.65%. In our study, there were 58 patients who passed away with a mortality rate of 66.66%. The cause of death was a complication of VTE in 22.42% and related to the course of cancer in 63.79% of cases. CONCLUSION VTE during cancer is particular with a fatal evolution due to the severity of VTE and the very advanced stage of cancer.

Abstract
BACKGROUND Esophagogastroduodenoscopy (EGD) is vital for the diagnosis and treatment of various gastrointestinal conditions but carries a low risk of venous air embolism (VAE). We report a case of VAE during EGD, confirmed by computed tomographic pulmonary angiography (CTPA). CASE A 56-year-old male with a history of hypopharyngeal cancer underwent EGD for dysphagia-related esophageal dilation. Signs of VAE were noted, prompting swift interventions, including oxygen therapy, positional changes, and CTPA. CTPA revealed the Mercedes-Benz sign, pneumomediastinum, and a minimal pneumothorax. The patient's oxygen saturation improved within 30 min before undergoing CTPA, and he was discharged on postoperative day 4. CONCLUSIONS Timely recognition of VAE, resulting in appropriate interventions supported by CTPA, resulted in favorable patient outcomes.

Abstract
PURPOSE To evaluate effectiveness and safety of large-bore mechanical thrombectomy of intermediate- or high-risk pulmonary embolism (PE) and factors associated with effectiveness. MATERIALS AND METHODS A retrospective review of 257 patients with intermediate- or high-risk PE who underwent mechanical thrombectomy using the Flowtriever system (Inari Medical, Irvine, California) between July 2019 and November 2021 was conducted. Data were analyzed using the linear regression and Kaplan-Meier methods with a Type 1 error set at 0.05. RESULTS Patients' mean age was 62 years, and 51% were male. PE risk was classified as high, intermediate-high, and intermediate-low in 37 (14%), 201 (78%), and 18 (7%) of the patients, respectively. Procedural technical success was 100%. The mean pulmonary artery pressure (MPAP) decreased from a mean of 32 mmHg (SD ± 9) before to 24 mmHg (SD ± 9) after thrombectomy (mean decrease, 8 mmHg [SD ± 6]; P < .0001). Immediate complications occurred in 2% of the patients. Postprocedural 30-day and all-time PE-attributable mortality in a mean of 1.3-year follow-up was 2% and 6%, respectively. In multivariate analysis, the presence of lower extremity DVT at presentation (β ± SE, -7.60 ± 3.22; P = .019) and a higher prethrombectomy MPAP (β ± SE, -0.19 ± 0.04; P < .001) were associated with lower degrees of decrease in MPAP in the intermediate-high-risk PE group. Among 14 patients with postthrombectomy PE-attributable mortality, 13 had postthrombectomy MPAPs of >20 mmHg. CONCLUSIONS Large-bore aspiration thrombectomy is a safe and effective treatment for reducing PAP in patients with intermediate- or high-risk PE. Postthrombectomy MPAPs of >20 mmHg might indicate postthrombectomy PE-attributable mortality in high-risk patients.

Abstract
INTRODUCTION AND OBJECTIVE Venous thromboembolism (VTE) is one of the most important and life-threatening complications in orthopaedic surgery. According to current scientific reports, there are several variables that can affect the severity of CVD, including the site of the pathology or the type of treatment implemented. The aim of the study was to analyze the risk of VTE depending on the location of the pathology, as well as to evaluate the impact of surgical treatment compared to conservative management. MATERIAL AND METHODS Analysis of laboratory results and clinical picture of 276 patients hospitalized for orthopaedic reasons, admitted between January 2008 - December 2019, with suspected pulmonary embolism (PE). RESULTS Among patients diagnosed with PE, the most common location of the disease was in the lower limb 59/116 (50.9%), followed by the pelvis location - 22/116 (19.0%), the spine - 19/116 (16.4%), disseminated lesions in oncological patients - 12/116 (10.3%), and a group of pathologies in the upper limb - 4/116 (3.5%). Significant statistical differences were found between the incidence of PE and the diagnosis of pathology in the lower limb and the pelvis. In the group of patients, there was no statistically significant relationship between the incidence of PE associated with surgical treatment, compared to conservative management. CONCLUSIONS The group with the highest risk of VTE were lower limb and pelvic pathologies. The results are largely consistent with numerous reports treating the risk of CVD among orthopaedic patient populations.

Abstract
Inferior vena cava (IVC) filters are engineered medical devices deployed in the IVC primarily to prevent a pulmonary embolism from occurring. In this article, we present a case of an IVC filter that was successfully retrieved from a patient after being in place for 34 years. The patient presented to hospital for trauma in which subsequent imaging showed tines of an IVC filter protruding outside of the vessel with one of the tines penetrating the duodenal wall. The filter was successfully removed with no complications. This report adds to the existing literature by yielding an example of an adverse risk that can be associated with the placement of IVC filters. In addition, to the authors' best knowledge, this is the longest reported length of time that an IVC filter has stayed in a patient before being removed, thus adding another intriguing detail to the case.

Abstract
BACKGROUND The global trend toward increased life expectancy because of remarkable improvements in health care quality has drawn increased attention to osteoporotic fractures and degenerative spine diseases. Cement-augmented pedicle screw fixation has been established as the mainstay treatment for patients with poor bone quality. This study aimed to determine the number of patients with cement leakage and pulmonary cement embolism (PCE) as detected on thoracic computed tomography (CT), and to assess the potential risk factors for PCE. METHODS Patients undergoing cement-augmented pedicle screw placement in our institution between May 2008 and December 2020 were included. Data regarding baseline characteristics, complications, and cement leakage rates were collected. Indications for the performance of a postoperative thoracic CT due to the suspicion of PCE were intra- or postoperative complications, or postoperative oxygen supplementation. Moreover, PCE was accidently diagnosed because the thoracic CT was performed for medical reasons other than the suspicion of PCE (tumor staging, severe pneumonia, or exacerbated chronic pulmonary obstructive disease). RESULTS A total of 104 patients with a mean age of 72.8 years (standard deviation of 6.7) were included. Of 802 screws, 573 were cement augmented. Of the 104 patients, 44 (42.3%) underwent thoracic CT scans to diagnose PCE; additionally, 67 (64.4%) demonstrated cement leakage, of whom 27 developed PCE and 4 were symptomatic. Cement-augmented thoracic screws were a risk factor for PCE (odds ratio: 1.5; 95% confidence interval: 1.2-2.1; p = 0.004). CONCLUSIONS This study showed a high prevalence of cement leakage after cement-augmented pedicle screw insertion, with a relatively frequent incidence of PCE, as tracked by thoracic CT scans. Cement-augmented thoracic screw placement was a unique risk factor for PCE.

Abstract
Pulmonary embolism (PE) is a leading preventable cause of death in surgical patients, and rates of fatal PE are increasing. Individual assessment, to balance the risks of thrombosis and bleeding, is the key to providing appropriate prophylaxis. The risk assessment process includes use of evidence-based guidelines, literature published since the latest guidelines, large registries, and risk scoring systems together with clinical experience and judgment. Risk assessment is a dynamic process and needs to be updated both during the hospital stay and just prior to discharge since clinical events may change the level of risk. The final assessment may identify patients who require ongoing anticoagulant prophylaxis after discharge. The Caprini risk score is widely used in surgical patients and is a composite of the number of risk factors and their relative weights. The Caprini risk score set point for risk levels requiring anticoagulant prophylaxis varies depending on the type of surgical procedure, surgical population, and number of risk factors. Mandatory implementation of evidence-based care pathways is helpful in lowering PE-related mortality. This review presents several challenging cases, emphasizing the importance of employing all available assessment tools, including dynamic assessment of risk during hospitalization. Finally, the limitations of evidence-based guidelines in complex scenarios and the need to employ all available tools to properly protect very high-risk patients are emphasized.

Abstract
BACKGROUND Pulmonary artery sarcomas (PAS) are rare tumours causing an insidiously progressive obstruction of the pulmonary circulation. The clinical presentation is often indistinguishable from chronic thromboembolic pulmonary hypertension (CTEPH). However, the atypical appearance of a heterogeneous filling defect in CT pulmonary angiography (CTPA) should prompt further investigation. CASE PRESENTATION A previously healthy young man presented with massive haemoptysis, acute respiratory distress, and progressive exertional dyspnea since the year before. Echocardiography demonstrated severe right ventricular dysfunction and highly probable pulmonary hypertension. CTPA revealed an extensive filling defect with an appearance concerning PAS. Due to syncopal episodes at rest, the patient underwent urgent pulmonary artery endarterectomy (PEA). A massive tree-like tumour was excised as a result. Post-operatively, reperfusion injury and refractory pulmonary oedema mandated extracorporeal membrane oxygenation (ECMO). Unfortunately, ECMO was complicated with massive haemolysis and acute kidney injury. The patient succumbed to multi-organ failure. Through tissue analysis established a diagnosis of embryonal rhabdomyosarcoma. DISCUSSION Unfortunately, the patient had not reached out for his worsening dyspnea. PASs should not be mistaken for a thrombus and anticoagulation should be avoided. The urgent condition precluded biopsy and tissue diagnosis. Similarly, neoadjuvant chemotherapy was not feasible. Post-operatively, reperfusion injury and pulmonary oedema ensued, which mandated ECMO. This complication should be anticipated preoperatively. There is a need for more data on PASs to establish a consensus for management.

Abstract
BACKGROUND The COVID-19 pandemic introduced a new set of challenges for the arthroplasty community, including the management of patients diagnosed with COVID-19 following revision total knee arthroplasty (rTKA) and its potential impact on postoperative recovery. This study sought to characterize the risks of postoperative COVID-19 infection among rTKA patients. METHODS A large national database was utilized to query 8,022 total patients who underwent rTKA between 2018 and 2021, of which 60 had a COVID diagnosis within 90 days after surgery (rTKA/COVID positive). These patients were 1:10 propensity-score matched to 600 rTKA patients who did not have a 90-day postoperative COVID diagnosis (rTKA/COVID negative) and 600 COVID positive patients who did not undergo rTKA. Controlling for potential confounders, multivariate logistic regressions were utilized to compare 90-day postoperative complications between groups. RESULTS Compared to rTKA/COVID negativepatients, the rTKA/COVID positive cohort had significantly higher rates of pneumonia (odds ratio [OR] = 6.1, P < .001), pulmonary embolism (PE) (OR = 32.4, P < .001), deep venous thrombosis (DVT) (OR = 32.4, P < .001), and 90-day readmissions (OR = 2.1, P = .02). Similarly, the rTKA/COVID positive cohort had significantly higher rates of pneumonia (OR = 4.3, P = .001), PE (OR = 36.8, P < .001), and DVT (OR = 36.8, P < .001) compared to COVID positive patients who did not undergo rTKA. CONCLUSIONS Revision total knee arthroplasty patients diagnosed with COVID-19 postoperatively had increased rates of thromboembolic events, pneumoniae, and 90-day readmissions. Risk mitigation efforts would suggest extending the prophylactic anticoagulation period for rTKA patients diagnosed with postoperative COVID-19.
