Abstract
BACKGROUND Cerebral sinus venous thrombosis (CSVT) is an uncommon condition in children with potentially serious outcomes. Large epidemiological studies in children with CSVT are few. The objective of this study is to evaluate the epidemiology and in-hospital outcomes of hospitalized children with CSVT in the United States. METHODS We performed a retrospective cross-sectional analysis of the Healthcare Cost and Utilization Project Kids' Inpatient Database for the combined years 2016 and 2019. The database was queried using the diagnoses for intracranial and intraspinal phlebitis and thrombophlebitis, nonpyogenic thrombosis of the intracranial venous system, and cerebral infarction due to cerebral venous thrombosis. Sample weighting was employed to produce national estimates. RESULTS Of 12,165,621 discharges, 3202 had CSVT (in-hospital prevalence 26.3 per 100,000 discharges). Male patients accounted for 57% of CSVT discharges. The median age was 8 years (interquartile range 1-16), with a U-shaped distribution with peaks in patients younger than 4 years and patients aged between 18 and 20 years. A total of 19.3% of children with CSVT had either hemorrhagic or ischemic stroke. Patients with stroke were more likely to require mechanical ventilation (odds ratio [OR] 2.7; 95% confidence interval [CI] 2.1-3.3; p < 0.001) and have higher mortality (OR 2.3; 95% CI 1.6-3.4; p < 0.001). Mechanical ventilation was necessary for 25.2% of patients with CSVT, of whom the majority were neonates and young children. The need for mechanical ventilation was associated with increased mortality (OR 16.6; 95% CI 9.9-27.9; p < 0.001). The overall mortality rate for CSVT was 4.1%, and 16.5% of patients with CSVT were discharged with home health care or to a skilled nursing facility. CONCLUSIONS CSVT, which has a U-shaped age distribution, is an uncommon condition in children. Stroke is common in children with CSVT, and it is associated with an increased need for mechanical ventilation and increased mortality. The need for mechanical ventilation is more common in infants, and it is associated with increased mortality across all age groups.

Abstract
BACKGROUND Thrombosis is a serious condition in children and neonates. However, the risk factors for thrombosis have not been conclusively determined. This study aimed to identify the risk factors for thrombosis in children and neonates in Intensive Care Unit (ICU) through a meta-analysis to better guide clinical treatment. METHODS A systematic search of electronic databases (PubMed, Embase, Cochrane Library, WOS, CNKI, Wanfang, VIP) was conducted to retrieve studies from creation on 23 May 2022. Data on the year of publication, study design, country of origin, number of patients/controls, ethnicity, and type of thrombus were extracted. The publication bias and heterogeneity between studies were assessed, and pooled odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using fixed or random effects models. RESULTS A total of 18 studies met the inclusion criteria. The incidence of thrombosis in children was 2% per year (95% CI 1%-2%, P < 0.01). Infection and sepsis (OR = 1.95, P < 0.01), CVC (OR = 3.66, [95%CL 1.78-7.51], P < 0.01), mechanical ventilation (OR = 2.1, [95%CL1.47-3.01], P < 0.01), surgery (OR = 2.25, [95%CL1.2-4.22], P < 0.01), respiratory distress (OR = 1.39, [95%CL0.42-4.63], P < 0.01), ethnicities (OR = 0.88, [95%CL 0.79-0.98], P = 0.78), gestational age (OR = 1.5, [95%CL1.34-1.68], P = 0.65)were identified as risk factors for thrombosis. CONCLUSIONS This meta-analysis suggests that CVC, Surgery, mechanical ventilation, Infection/sepsis, gestational age, Respiratory distress, and different ethnicities are risk factors for thrombosis in children and neonates in ICU. These findings may help clinicians to identify high-risk patients and develop appropriate prevention strategies. TRIAL REGISTRATION PROSPERO (CRD 42022333449).

Abstract
PURPOSE OF REVIEW Central venous catheter (CVC) placement and ICU admission are the two most important risk factors for pediatric deep vein thrombosis. The optimal prevention and treatment strategies for CVC-associated deep vein thrombosis (CADVT) are unclear, but recently, seminal studies have been published. This review aims to summarize the recent literature on CADVT in critically ill children. RECENT FINDINGS Recent publications focused on three themes: risk factors, prevention, and treatment of CADVT. Newly identified risk factors for CADVT relate to Virchow's triad of hemostasis, blood vessel injury, and hypercoagulability. New risk prediction models have moderately good accuracy in predicting CADVT. Though previous data on pharmacologic CADVT prophylaxis was equivocal, recent studies indicate that low-molecular-weight heparin may be effective in preventing CADVT, particularly in critically ill children. Finally, new studies suggest that direct oral anticoagulants and shorter treatment times are noninferior to traditional agents and treatment durations in the treatment of CADVT. SUMMARY Recent research suggests new ways to accurately identify children at high risk of CADVT, effectively prevent CADVT, and optimize CADVT treatment. Future research should focus on understanding the pathobiology of CADVT formation, prevention, and treatment in critically ill children.

Abstract
BACKGROUND Central venous catheter (CVC) related venous thrombosis (VT) following pediatric cardiac surgery increases the morbidity and mortality. Although VT prevention using low dose anticoagulation has proven ineffective, anticoagulation using high dose enoxaparin to achieve a therapeutic anti-xa level has not been studied. We hypothesized that high dose enoxaparin would reduce VT after pediatric cardiac surgery. METHODS Enoxaparin was administered to infants < 150 days when post-operative CVC duration was anticipated to extend beyond 5 days. The primary outcome was the rate of VT, re-exploration for bleeding, and post-operative red blood cell (RBC) transfusions per 1,000 CVC days. RESULTS From 2012-2019, 157 infants were treated with enoxaparin. Infants were divided into two groups: 1) SubTherapeutic (SubTher) (N = 51) - therapeutic anti-xa level (0.5-1.0 IU/mL) was not achieved, 2) Therapeutic (Ther) (N = 106) - therapeutic anti-xa level was achieved. Baseline demographics demonstrated a lower age at operation within the Ther group. The SubTher group had a higher VT rate/1,000 CVC days (8.2) compared to the Ther group (2.6; p=0.005). Re-exploration for bleeding was similar between groups. The number of post-operative RBC transfusions/1,000 CVC days was significantly greater in the SubTher group (109.4 vs. 81.6; p=0.008). Multivariate analysis demonstrated that higher median anti-xa levels reduced the risk of VT (OR 0.02, CI: 0.001, 0.63; p = 0.02). CONCLUSIONS This data suggests that enoxaparin treatment resulting in a therapeutic anti-xa level reduces post-operative CVC associated VT without increasing bleeding complications.

Risk factors for pediatric cerebral sinovenous thrombosis: A case-control study with case validation. Thromb Res 2020; 194:8-15.

Abstract
INTRODUCTION Cerebral sinovenous thrombosis (CSVT) represents the second most common type of venous thromboembolism (VTE) in children. Current literature includes limited evidence on risk factors for CSVT, particularly in the pediatric population. We sought to determine risk factors for CSVT in pediatric patients through a single-institutional case-control study. In addition, we evaluated thrombophilias, treatments and outcomes in CSVT among cases. METHODS A case-control study was performed at Johns Hopkins All Children's Hospital on patients admitted from March 31, 2006 through April 1, 2018. Cases were identified using diagnostic codes and confirmed based on electronic health record (EHR) and neuroimaging review. Controls were matched in a 2:1 fashion accounting for the month and year of admission. RESULTS A total of 60 CSVT cases and 120 controls were identified. Median (range) age was 4.8 years (0-21.3 years) for cases and 5.6 years (0-20.0 years) for controls. Factors putatively associated with CSVT in unadjusted analyses were: corticosteroid use, presence of a central venous catheter, mechanical ventilation, systemic infection, head/neck infection, head/neck trauma, and chronic inflammatory disease. In the multivariable model, head/neck infection (OR: 13.8, 95% CI: 4.87-38.7; P < 0.01), head/neck trauma (OR: 12.7, 95% CI: 2.88-56.2; P < 0.01), and mechanical ventilation (OR: 9.32, 95% CI: 2.35-36.9; P = 0.01) remained independent, statistically-significant risk factors. 61% of patients were subacutely treated with anticoagulants and of those, only two developed relevant bleeding after initiation of therapy. CONCLUSIONS This single-institutional case-control study reveals that head/neck infection, head/neck trauma, and mechanical ventilation are independent risk factors for pediatric CSVT. These findings will be further investigated via a cooperative registry of pediatric hospital-acquired VTE, by which a risk model for pediatric CSVT will be developed and validated, in order to inform future preventive strategies in at-risk pediatric patients.

Abstract
BACKGROUND Central venous catheter (CVC) use is common in the management of critically ill children, especially those with congenital heart disease. CVCs are known to augment the risk of deep vein thrombosis (DVT), but data on CVC-associated DVTs in the pediatric cardiac intensive care unit (CICU) are limited. In this study, we aim to identify the incidence of and risk factors for CVC-related DVT in this high-risk population, as its complications are highly morbid. MATERIALS AND METHODS The PC4 database and a radiologic imaging database were retrospectively reviewed for the demographics and outcomes of patients admitted to the Texas Children's Hospital CICU requiring CVC placement, as well as the incidence of DVT and its complications. RESULTS Between January 2017 and December 2017, 1215 central lines were placed over 851 admissions. DVT was diagnosed in 8% of admissions with a CVC, 29% of which demonstrated thrombus in the inferior vena cava. The risk factors significantly associated with DVT included the presence of >1 line, higher total line hours, longer intubation times, and extended CICU stay. A diagnosis of low cardiac output syndrome, sepsis, central line-associated bloodstream infection, and cardiac catheterization were also significant risk factors. Interestingly, cardiac surgery with cardiopulmonary bypass appeared to be protective of clot development. DVT was a highly significant risk factor for mortality in these patients. CONCLUSIONS CVC-related DVTs in critically ill children with congenital heart disease are associated with higher risks of morbidity and mortality, highlighting the need for well-designed studies to determine the best preventative and treatment strategies and to establish guidelines for appropriate monitoring and follow-up of these patients.

Abstract
OBJECTIVE To determine the epidemiology of lower extremity deep venous thrombosis (DVT) in critically ill adolescents, which currently is unclear. STUDY DESIGN We performed a multicenter, prospective, cohort study. Adolescents aged 13-17 years who were admitted to 6 pediatric intensive care units and were anticipated to receive cardiopulmonary support for at least 48 hours were eligible, unless they were admitted with DVT or pulmonary embolism or were receiving or anticipated to receive therapeutic anticoagulation. While patients were in the unit, serial sonograms of the lower extremities were performed, then centrally adjudicated. Bayesian statistics were used to leverage the similarities between adults and adolescents. RESULTS A total of 88 adolescents were enrolled, from whom 184 lower extremity sonograms were performed. Of these, 9 adolescents developed DVT, with 1 having bilateral DVT. The frequency of DVT was 12.4% (95% credible interval: 6.1%, 20.1%), which ranged from 6.3% to 19.8% with a variability of 41.0% across units. All cases of DVT occurred in adolescents who received invasive mechanical ventilation (frequency: 16.5%; 95% credible interval 8.1%, 26.6%). DVT was associated with femoral central venous catheterization (OR 15.44; 95% credible interval 1.62, 69.05) and severe illness (OR for every 0.1 increase in risk of mortality 3.11; 95% credible interval 1.19, 6.85). DVT appears to be associated with prolonged days on support. CONCLUSIONS Our findings highlight the similarities and differences in the epidemiology of DVT between adults and adolescents. They support the conduct and inform the design of a trial of pharmacologic prophylaxis in critically ill adolescents.

Abstract
BACKGROUND Venous thromboembolism (VTE) in pediatric surgical patients is a rare event. The risk factors for VTE in pediatric general surgery patients undergoing abdominopelvic procedures are unknown. STUDY DESIGN The American College of Surgeon's National Surgical Quality Improvement Program-Pediatric (NSQIP-P) database (2012-2015) was queried for patients with VTE after abdominopelvic general surgery procedures. Patient and operative variables were assessed to identify risk factors associated with VTE and develop a pediatric risk score. RESULTS From 2012-2015, 68 of 34,813 (0.20%) patients who underwent abdominopelvic general surgery procedures were diagnosed with VTE. On multivariate analysis, there was no increased risk of VTE based on concomitant malignancy, chemotherapy, inflammatory bowel disease, or laparoscopic surgical approach, while a higher rate of VTE was identified among female patients. The odds of experiencing VTE were increased on stepwise regression for patients older than 15 years and those with preexisting renal failure or a diagnosis of septic shock, patients with American Society of Anesthesia (ASA) classification ≥ 2, and for anesthesia time longer than 2 h. The combination of age > 15 years, ASA classification ≥ 2, anesthesia time > 2 h, renal failure, and septic shock was included in a model for predicting risk of VTE (AUC = 0.907, sensitivity 84.4%, specificity 88.2%). CONCLUSION VTE is rare in pediatric patients, but prediction modeling may help identify those patients at heightened risk. Additional studies are needed to validate the factors identified in this study in a risk assessment model as well as to assess the efficacy and cost-effectiveness of prophylaxis methods. LEVEL OF EVIDENCE Level III, retrospective comparative study.

Abstract
Venous thromboembolism, which includes deep venous thrombosis and pulmonary embolism, is a potentially preventable condition in children. In adults, pharmacologic prophylaxis has been shown to significantly reduce the incidence of venous thromboembolism in distinct patient cohorts. However, pediatric randomized controlled trials have failed to demonstrate the efficacy of pharmacologic prophylaxis against thrombosis associated with central venous catheters, the most important risk factor for venous thromboembolism in children. Despite the lack of supporting evidence, hospital-based initiatives are being undertaken to try to prevent venous thromboembolism in children. In this study, we sought to review the published guidelines on the prevention of venous thromboembolism in hospitalized children. We identified five guidelines, all of which were mainly targeted at adolescents and used various risk-stratification approaches. In low-risk children, ambulation was the recommended prevention strategy, while mechanical prophylaxis was recommended for children at moderate risk and pharmacologic and mechanical prophylaxis were recommended for the high-risk group. The effectiveness of these strategies has not been proven. In order to determine whether venous thromboembolism can be prevented in children, innovative clinical trial designs are needed. In the absence of these trials, guidelines can be a source of valuable information to inform our practice.

Abstract
PURPOSE In preparation for a randomized controlled trial of prophylaxis against catheter-associated deep venous thrombosis in critically ill children, we aimed to determine clinical equipoise, defined as willingness to randomize children, among pediatric critical care physicians. MATERIALS AND METHODS We conducted a cross-sectional, self-administered electronic survey of pediatric critical care physicians in the United States. The survey focused on the effect of child's age, presence of a central venous catheter, and risk (ie, presence of coagulopathy or recent surgery) and presence of bleeding on their willingness to randomize children to an anticoagulant or placebo. RESULTS Responses from 239 (33.0%) of 725 physicians were analyzed. Respondents were willing to randomize children 1 month or older in the presence of a catheter but only those older than 13 years in the absence of a catheter. For children with coagulopathy, they would randomize those with international normalized ratio less than or equal to 2.0, partial thromboplastin time less than or equal to 50 seconds, and platelet count greater than or equal to 50000/mm(3). Respondents were willing to randomize children 2 days after most types of surgery and after 1 to 5 days of a bleeding event. CONCLUSIONS Clinical equipoise on prophylaxis against catheter-associated thrombosis exists among pediatric critical care physicians, which ethically justifies conducting a randomized controlled trial.

Abstract
Venous thromboembolic events are rare in pediatric patients. Risk factors associated with the development of venous thromboembolic events in pediatric patients include the use of central venous catheters, hospitalization, cancer, sepsis, trauma, surgery, and congenital prothrombotic disorders.The authors present the case of a 14-year-old man with Crouzon syndrome who required Le Fort III osteotomy with rigid external distraction for significant midface hypoplasia who presented postoperatively with an extensive deep venous thrombosis. This is the first reported case of symptomatic venous thrombosis post-Le Fort III osteotomy and rigid external distraction. Although rare, surgeons should be aware of this potential complication.

Abstract
Prescription of thromboprophylaxis is not a common practice in pediatric intensive care units. Most thrombi are catheter-related and asymptomatic, without causing acute complications. However, chronic complications of these (a)symptomatic catheter-related thrombi, that is, postthrombotic syndrome (PTS) and residual thrombosis have not been studied. To investigate these complications, critically ill children of 1 tertiary center with percutaneous inserted femoral central venous catheters (FCVCs) were prospectively followed. Symptomatic FCVC-thrombosis occurred in 10 of the 134 children (7.5%; 95% confidence interval [CI], 2.4-9.5). Only FCVC-infection appeared to be independently associated (P=0.001) with FCVC-thrombosis. At follow-up 2 of the 5 survivors diagnosed with symptomatic thrombosis developed mild PTS; one of them had an occluded vein on ultrasonography. A survivor without PTS had a partial occluded vein at follow-up. Asymptomatic FCVC-thrombosis occurred in 3 of the 42 children (7.1%; 95% CI, 0.0-16.7) screened by ultrasonography within 72 hours after catheter removal. At follow-up, mild PTS was present in 6 of the 33 (18.2%; 95% CI, 6.1-30.3) screened children. Partial and total vein occlusion was present in 1 (3%) and 4 (12%) children, respectively. In conclusion, children on pediatric intensive care units are at risk for (a)symptomatic FCVC-thrombosis, especially children with FCVC-infection. Chronic complications of FCVC-thrombosis are common. Therefore, thromboprophylaxis guidelines are warranted in pediatric intensive care units to minimize morbidity as a result of FCVC-thrombosis.

Abstract
OBJECTIVE If we can identify critically ill children at high risk for central venous catheter-related thrombosis, then we could target them for pharmacologic thromboprophylaxis. We determined whether factor VIII activity or G value was associated with catheter-related thrombosis in critically ill children. DESIGN Prospective cohort study. SETTING Two tertiary academic centers. PATIENTS We enrolled children younger than 18 years who were admitted to the PICU within 24 hours after insertion of a central venous catheter. We excluded children with a recently diagnosed thrombotic event or those anticipated to receive anticoagulation. Children with thrombosis diagnosed with surveillance ultrasonography on the day of enrollment were classified as having prevalent thrombosis. Those who developed catheter-related thrombosis thereafter were classified as having incident thrombosis. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS We enrolled 85 children in the study. Once enrolled, we measured factor VIII activity with one-stage clotting assay and determined G value with thromboelastography. Of those enrolled, 25 had incident and 12 had prevalent thromboses. The odds ratio for incident thrombosis per SD increase in factor VIII activity was 1.98 (95% CI, 1.10-3.55). The area under the receiver operating characteristic curve was 0.66 (95% CI, 0.52-0.79). At factor VIII activity more than 100 IU/dL, which was the optimal threshold identified using Youden index, sensitivity and specificity were 92.0% and 41.3%, respectively. The association between factor VIII activity and incident thrombosis remained significant after adjusting for important clinical predictors of thrombosis (odds ratio, 1.93; 95% CI, 1.10-3.39). G value was associated with prevalent but not with incident thrombosis. CONCLUSION Factor VIII activity may be used to stratify critically ill children based on their risk for catheter-related thrombosis.

Abstract
OBJECTIVES Although critically ill children are at increased risk for developing deep venous thrombosis, there are few pediatric studies establishing the prevalence of thrombosis or the efficacy of thromboprophylaxis. We tested the hypothesis that thromboprophylaxis is infrequently used in critically ill children even for those in whom it is indicated. DESIGN Prospective multinational cross-sectional study over four study dates in 2012. SETTING Fifty-nine PICUs in Australia, Canada, New Zealand, Portugal, Singapore, Spain, and the United States. PATIENTS All patients less than 18 years old in the PICU during the study dates and times were included in the study, unless the patients were 1) boarding in the unit waiting for a bed outside the PICU or 2) receiving therapeutic anticoagulation. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Of 2,484 children in the study, 2,159 (86.9%) had greater than or equal to 1 risk factor for thrombosis. Only 308 children (12.4%) were receiving pharmacologic thromboprophylaxis (e.g., aspirin, low-molecular-weight heparin, or unfractionated heparin). Of 430 children indicated to receive pharmacologic thromboprophylaxis based on consensus recommendations, only 149 (34.7%) were receiving it. Mechanical thromboprophylaxis was used in 156 of 655 children (23.8%) 8 years old or older, the youngest age for that device. Using nonlinear mixed effects model, presence of cyanotic congenital heart disease (odds ratio, 7.35; p < 0.001) and spinal cord injury (odds ratio, 8.85; p = 0.008) strongly predicted the use of pharmacologic and mechanical thromboprophylaxis, respectively. CONCLUSIONS Thromboprophylaxis is infrequently used in critically ill children. This is true even for children at high risk of thrombosis where consensus guidelines recommend pharmacologic thromboprophylaxis.

Abstract
INTRODUCTION Although critically ill children may be at risk from developing deep venous thrombosis (DVT), data on its incidence and effectiveness of thromboprophylaxis are lacking. OBJECTIVE To describe the use of thromboprophylaxis in critically ill children in Spain and Portugal, and to compare the results with international data. MATERIAL AND METHODS Secondary analysis of the multinational study PROTRACT, carried out in 59 PICUs from 7 developed countries (4 from Portugal and 6 in Spain). Data were collected from patients less than 18 years old, who did not receive therapeutic thromboprophylaxis. RESULTS A total of 308 patients in Spanish and Portuguese (Iberian) PICUS were compared with 2176 admitted to international PICUs. Risk factors such as femoral vein (P=.01), jugular vein central catheter (P<.001), cancer (P=.03), and sepsis (P<.001), were more frequent in Iberian PICUs. The percentage of patients with pharmacological thromboprophylaxis was similar in both groups (15.3% vs. 12.0%). Low molecular weight heparin was used more frequently in Iberian patients (P<.001). In treated children, prior history of thrombosis (P=.02), femoral vein catheter (P<.001), cancer (P=.02) and cranial trauma or craniectomy (P=.006), were more frequent in Iberian PICUs. Mechanical thromboprophylaxis was used in only 6.8% of candidates in Iberian PICUs, compared with 23.8% in the international PICUs (P<.001). CONCLUSIONS Despite the presence of risk factors for DVT in many patients, thromboprophylaxis is rarely prescribed, with low molecular weight heparin being the most used drug. Passive thromboprophylaxis use is anecdotal. There should be a consensus on guidelines of thromboprophylaxis in critically ill children.

Abstract
BACKGROUND The ability to predict the development of venous thromboembolism is highly desirable. OBJECTIVE We aim to determine the association between hyperglycemia and venous thromboembolism in non-diabetic critically ill children. PATIENTS/METHODS We conducted a retrospective cohort study that included children in the pediatric intensive care unit on a vasopressor or mechanical ventilator and without history of diabetes mellitus or prior diagnosis of thrombosis. Based on maximum blood glucose > 150 mg dL(-1) while admitted to the unit, children were categorized as hyperglycemic or non-hyperglycemic. The primary outcome was development of venous thromboembolism while admitted to the unit. We determined the association between hyperglycemia and venous thromboembolism using logistic regression models adjusting for selected subject characteristics. RESULTS Of the 789 subjects analyzed, 34 subjects developed venous thromboembolism (incidence, 4.3%; 95% confidence interval, 3-6%). Venous thromboembolism was more likely to develop in hyperglycemic subjects compared with non-hyperglycemic subjects. A total of 31 subjects (6.2%; 95% confidence interval, 4.2-8.7%) developed venous thromboembolism after becoming hyperglycemic compared with three non-hyperglycemic subjects with venous thromboembolism (1%; 95% confidence interval, 0.2-3%). When adjusted for age, diagnosis, presence of central venous catheter, prophylactic antithrombotic use and severity of illness, the odds ratio of venous thromboembolism with hyperglycemia was 4.1 (95% confidence interval, 1.2-14.1). For every 10 mg dL(-1) increase in maximum blood glucose, the adjusted odds ratio of venous thromboembolism was 1.04 (95% confidence interval, 1.01-1.06). CONCLUSION Hyperglycemia is associated with venous thromboembolism in critically ill non-diabetic children. Maximum blood glucose is a potential predictor of venous thromboembolism in this population.

Abstract
PURPOSE OF REVIEW To review the current literature on venous thromboembolism (VTE) in critically ill children. RECENT FINDINGS There is an increasing concern for VTE and its complications in critically ill children. Critically ill children are at increased risk of thromboembolism because of the treatment that they are receiving and their underlying condition. A complex relationship exists between thrombosis and infection. A thrombus is a nidus for infection, while infection increases the risk of thrombosis. Pediatric-specific guidelines for the prevention and treatment of thromboembolism are lacking. Current guidelines are based on the data from adults. Novel anticoagulants are now available for use in adults. Studies are ongoing to determine their safety in children. Risk assessment tools have recently been developed to determine the risk of thromboembolism in critically ill children. Certain molecules are associated with thromboembolism in adults. SUMMARY Pediatric critical care practitioners should be cognizant of the importance of VTE in critically ill children to allow early identification and treatment. Adequately powered clinical trials are critically needed to generate evidence that will guide the treatment and prevention of thromboembolism in critically ill children. Risk assessment tools that incorporate biomarkers may improve our ability to predict the occurrence of thromboembolism in critically ill children.

Abstract
OBJECTIVE To determined the current incidence and acute complications of asymptomatic central venous catheter (CVC)-related deep venous thrombosis (DVT) in critically ill children. STUDY DESIGN We performed a prospective cohort study in 3 pediatric intensive care units. A total of 101 children with newly inserted untunneled CVC were included. CVC-related DVT was diagnosed using compression ultrasonography with color Doppler. RESULTS Asymptomatic CVC-related DVT was diagnosed in 16 (15.8%) children, which equated to 24.7 cases per 1000 CVC-days. Age was independently associated with DVT. Compared with children aged <1 year, children aged >13 years had significantly higher odds of DVT (aOR, 14.1, 95% CI, 1.9-105.8; P = .01). Other patient demographics, interventions (including anticoagulant use), and CVC characteristics did not differ between children with and without DVT. Mortality-adjusted duration of mechanical ventilation, a surrogate for pulmonary embolism, was statistically similar in the 2 groups (22 ± 9 days in children with DVT vs 23 ± 7 days in children without DVT; P = .34). Mortality-adjusted intensive care unit and hospital lengths of stay also were similar in the 2 groups. CONCLUSION Asymptomatic CVC-related DVT is common in critically ill children. However, the acute complications do not seem to differ between children with and without DVT. Larger studies are needed to confirm these results. Future studies should also investigate the chronic complications of asymptomatic CVC-related DVT.

Abstract
Venous thromboembolism (VTE) is an increasingly common complication encountered in tertiary care pediatric settings. The purpose of this review is to summarize the epidemiology, current and emerging pharmacotherapeutic options, and management of this disease. Over 70% of VTE occur in children with chronic diseases. Although they are seen in children of all ages, adolescents are at greatest risk. Pediatric VTE is associated with an increased risk of in-hospital mortality; recurrent VTE and post-thrombotic syndrome are commonly seen in survivors. In recent years, anticoagulation with low molecular weight heparin has emerged as the mainstay of therapy, but compliance is limited by its onerous subcutaneous administration route. New anticoagulants either already approved for use in adults or in the pipeline offer the possibility of improved dose stability and oral routes of administration. Current recommended anticoagulation course durations are derived from very limited case series and cohort data, or extrapolations from adult literature. However, the pathophysiologic underpinnings of pediatric VTE are dissimilar from those seen in adults and are often variable within groups of pediatric patients. Clinical studies and trials in pediatric VTE are underway which will hopefully improve the quality of evidence from which therapeutic guidelines are derived.
