Direct-Acting Oral Anticoagulants in the Management of Cerebral Venous Sinus Thrombosis-Where Do We Stand? Biomedicines 2025; 13:189. [PMID: 39857772 PMCID: PMC11759824 DOI: 10.3390/biomedicines13010189] [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: 11/26/2024] [Revised: 12/16/2024] [Accepted: 12/26/2024] [Indexed: 01/27/2025] Open
Abstract
BACKGROUND Cerebral venous sinus thrombosis (CVT) is a rare cause of stroke, constituting 0.5-3% of all strokes with an extremely varied spectrum of presentation, predisposing factors, neuroimaging findings, and eventual outcomes. A high index of suspicion is needed because timely diagnosis can significantly alter the natural course of the disease, reduce acute complications, and improve long-term outcomes. Due to its myriad causative factors, protean presentation, and association with several systemic diseases, CVT is encountered not only by neurologists but also by emergency care practitioners, internists, hematologists, obstetricians, and pediatricians. DISCUSSION Anticoagulation remains the mainstay of treatment for CVT. Heparin and warfarin previously had been the anticoagulation of choice. Recently there has been an increased interest in utilizing direct-acting oral anticoagulants in the treatment of CVT given comparable safety and efficacy with ease of utilization. However recent clinical guidelines given by multiple societies including the American Stroke guidelines and European guidelines do not include these agents so far in their treatment recommendations. Ongoing multicentric clinical trials are currently reviewing the role of these agents in both short-term as well as long-term. Our review of the literature supports the safety and reinforces the efficacy of DOAC in the treatment of CVT. Additionally, patient satisfaction has been shown to be better with the use of DOAC. In conclusion, DOAC continues to have a valid role in the management of CVT.

Comprehensive Analysis of Risk Factors and Prognostic Outcomes in Cases of Cerebral Venous and Sinus Thrombosis in a Tertiary Care Setting. Cureus 2024; 16:e68574. [PMID: 39371830 PMCID: PMC11449630 DOI: 10.7759/cureus.68574] [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: 07/23/2024] [Accepted: 09/03/2024] [Indexed: 10/08/2024] Open
Abstract
Background Cerebral venous and sinus thrombosis (CVT) is one of the most common causes of stroke in young people. With timely diagnosis and the right medical attention, this relatively rare neurologic condition may be curable. Finding the risk variables and outcome determinants is the aim of this study. Methodology A two-year prospective observational research was carried out in a tertiary care facility. Notable were the patient's demographics, symptomatology, and risk factor history. The Modified Rankin Scale (mRS) was employed to assess the patient's outcome and prognosis both at admission and after six weeks. The mRS scores at admission and follow-up were compared concerning outcome factors using the chi-square test. Results In all, there were 75 people with CVT. More men (42 patients, 56%) than women (33 patients, 44%), particularly in their third decade, were impacted. Polycythemia (22 patients, 29.3%) was the most prevalent risk factor, followed by the use of oral contraceptives (14 patients, 18.7%). Based on their mRS scores upon entry, 38 individuals (50.7%) were classified as functionally independent (mRS < 2), whereas 37 individuals (49.3%) were deemed functionally dependent (mRS > 2). At the six-week follow-up, 54 patients (72%) were functionally independent. Decompressive craniotomies were performed on 15 patients (20%), of which 10 (13.33%) had improvement, two (2.67%) had deterioration, and one patient passed away. The percentage of deaths was 1.33%. Two patients (2.67%) were not followed up with. Conclusion The present findings highlight that CVT predominantly affects younger individuals with a slight male predominance. The leading risk factors were polycythemia and the use of oral contraceptive pills (OCPs). Despite generally favorable prognoses with appropriate management, poorer outcomes were linked to altered consciousness, neurological deficits, and intracerebral hemorrhage (ICH) at presentation.

Abstract
OBJECTIVE We aimed to describe clinical and laboratory characteristics and determine the predictors of outcome in patients with cerebral venous sinus thrombosis. METHODS This prospective study was conducted over 2 years among hospitalized patients with cerebral venous sinus thrombosis. Patient outcome was assessed using the Modified Rankin Scale (mRS) score at 3 months. Outcome predictors were identified using logistic regression analysis. RESULTS Eighty-one patients were included in this study. The median mRS outcome at 3 months was 1 (interquartile range 1-3). Poor outcomes were observed in 27.2% of patients, and the mortality rate was 9.8%. Factors associated with poor outcomes were age >60 years (relative risk [RR] 5.1), hemiparesis (RR 5.4), altered level of consciousness (RR 7.1), and transverse sinus involvement (RR 1.1). In general, mRS scores were not associated with D-dimer levels (RR 2.4). However, older patients with elevated D-dimer levels showed a significant association with poor outcomes (1.6) according to mRS scores. CONCLUSION Older age, hemiparesis, and altered consciousness levels were independent predictors of poor outcomes in patients with cerebral venous sinus thrombosis. High D-dimer level showed no association with functional disability, except in older patients.

Abstract
BACKGROUND To analyze the clinical and neuroimaging features, risk factors, treatment choices, and long-term clinical outcomes in children with cerebral sinus venous thrombosis (CSVT). METHODS This is a retrospective cohort study of children diagnosed with CSVT between 2002 and 2018 at Texas Children's Hospital. RESULTS A total of 183 children (male: 62.3%) with CSVT were included. The average presenting age was 7.7 years (S.D.: 5.6). The mean follow-up duration was 33.7 months (S.D.: 38.6). The most common presenting clinical feature was headache (36.6%). Head and neck infections other than meningitis (36.6%) were the most common risk factors. Prevalent neurological examination findings included motor deficit (21.3%) and altered mental status (AMS, 20.2%). Neuroimaging features included hemorrhagic infarction (19.6%), ischemic infarction (8.2%), and intracranial hemorrhage without infarction (5.5%). The most common site of thrombosis was the superior sagittal sinus (37.2%), with 78.2% of patients demonstrating involvement of multiple sinuses. Treatment of choice was low-molecular-weight heparin in 69.4% of patients. Factors associated with worse clinical outcomes included head and neck infections, malignancy (other than hematologic), cardiac disease, and recent surgery; seizure and dehydration on initial presentation; motor abnormalities and AMS on initial examination; ischemic infarct only; and involvement of vein of Trolard on neuroimaging. Thrombus condition on repeat imaging, receiving any anticoagulant/antithrombotic treatment, treatment duration, or follow-up duration was not associated with severity of long-term outcome. CONCLUSIONS CSVT may lead to unfavorable long-term outcomes in a remarkable portion of pediatric patients. Thus, a high index of suspicion and early and appropriate management of pediatric CSVT is imperative.

Abstract
Introduction Cerebral venous sinus thrombosis (CVST) is a cerebral vascular disorder that currently occurs quite often and has very varied clinical symptoms. Headache is the main symptom most commonly found in patients with CVST and multiple sinus involvement often have a more severe prognosis and poor clinical outcome. This study aimed to learn the relationship between D-dimer level, numeric rating scale (NRS), and amount of sinus involvement in CVST patients. Methods This study was a retrospective observational analytic study with a cross-sectional approach using medical records and supporting data (D-dimer level and imaging finding) on patients diagnosed with CVST at Dr Hasan Sadikin Hospital Bandung. Results Sixty-five CVST patients met the study criteria with mean age of 47 years and mostly female (76.9%). Patients with single sinus involvement had a median initial NRS of 4 (range 2-6) and multiple sinus involvement was higher at 8 (range 5-9). Statistical test results showed a significant difference between D-dimer level, NRS and amount of sinus involvement (P<0.001). Conclusion D-dimer level, NRS, and amount of sinus involvement are associated with amount of sinus involvement in CVST patients. Involvement of multiple sinus will cause higher NRS with higher D-dimer level.

Abstract
Cerebral venous sinus thrombosis (CVST) is a cerebrovascular condition due to the thrombosis of cerebral venous sinuses, leading to intracranial hemorrhage, increased intracranial pressure, focal deficit, seizure, toxic edema, encephalopathy, and death. The diagnosis and therapeutic approach of CVST remain challenging because of its highly nonspecific clinical presentation including headaches, seizures, focal neurologic deficits, and altered mental status, etc. Anticoagulation is the mainstay of CVST treatment and should be started as soon as the diagnosis is confirmed. Here, we present the case of a 34-year-old male construction worker who presented to the emergency department with a complaint of right chest wall pain and swelling. He was admitted to the hospital following a diagnosis of anterior chest wall abscess and mediastinitis. During hospitalization, his complete blood count revealed pancytopenia with blast cells, and bone marrow biopsy revealed 78.5% lymphoid blasts by aspirate differential count and hypercellular marrow (100%) with decreased hematopoiesis. He developed concurrent CVST and intracranial hemorrhage while receiving CALGB10403 (vincristine, daunorubicin, pegaspargase, prednisone) with intrathecal cytarabine induction chemotherapy for acute lymphoblastic leukemia (ALL). The patient failed two standard chemotherapy for ALL and achieved remission while on third-line chemotherapy with an anti-CD19 monoclonal antibody, blinatumomab. Although this patient had an MRI scan of the brain with multiple follow-up non-contrast CT scans, it was CT angiography that revealed CVST. This showed the diagnostic challenge in CVST, with CT and MRI venography having excellent sensitivity in diagnosing CVST. Risk factors for CVST in our patient were ALL and its intensive induction chemotherapy with pegaspargase.

Abstract
Long-term anticoagulation in the treatment of Cerebral Venous Sinus Thrombosis (CVST) has revolved around the use of warfarin. The relatively recent introduction of Direct Oral Anticoagulants (DOACs), such as Factor Xa inhibitors, in treating CVSTs promises to offer numerous patient benefits. We aimed to examine the efficacy of Factor Xa inhibitors in comparison to warfarin in the long-term treatment of CVSTs. A single-center retrospective analysis was conducted in which 49 eligible patients having presented with a first-time CVST were identified. Long-term anticoagulation was achieved with Warfarin (n = 23) or Factor Xa Inhibitors (n = 26; Apixaban or Rivaroxaban). Outcomes of interest were improvements in patient functional status, modified Ranking Scores (mRS), and radiographic improvement/resolution in sinus thromboses. Secondary comparisons included complication rates, particularly recurring venous thrombotic events. Patient mRS scores by 7-to-18-month follow-up all fell within the extremely favorable range of 0-1 regardless of the long-term anticoagulant (P-value = 0.3591). Proportion of patients with radiographic improvement/resolution of thrombosed sinuses trended towards being higher in the Factor Xa Inhibitor group at the <12-month period, 69.2%, compared to 33.3% with Warfarin (P-value = 0.0548). By the >12-month follow-up period, Warfarin and Factor Xa inhibitor groups had similar rates of radiographic sinus improvement - 76.9% versus 71.4%, respectively (P-value = 0.6298). No statistically significant differences were documented between groups regarding complications. Factor Xa inhibitors are equally as effective as Warfarin in the long-term treatment of CVSTs, whether it be restoring patient functional status, sinus thrombus burden reduction, or minimizing bleeding complications whilst preventing recurrent venous thrombosis.

Abstract
The sellar, suprasellar, and parasellar space contain a vast array of pathologies, including neoplastic, congenital, vascular, inflammatory, and infectious etiologies. Symptoms, if present, include a combination of headache, eye pain, ophthalmoplegia, visual field deficits, cranial neuropathy, and endocrine manifestations. A special focus is paid to key features on CT and MRI that can help in differentiating different pathologies. While most lesions ultimately require histopathologic evaluation, expert knowledge of skull base anatomy in combination with awareness of key imaging features can be useful in limiting the differential diagnosis and guiding management. Surgical techniques, including endoscopic endonasal and transcranial neurosurgical approaches are described in detail.

Abstract
Objectives There is a higher prevalence of cerebral venous sinus thrombosis (CVST) in more recent times, owing to increased awareness, clinical diagnostic skills, and advancements in neuroimaging modalities. This study aimed to identify and characterize the geographical, clinical, and etiological profiles of patients with CVST that may be relevant to planning appropriate diagnostic and therapeutic strategies to improve functional recovery. Methods and Results A retrospective observational study was carried out at a tertiary care hospital between March 2014 and October 2018. The demographics and clinical profile of the hospitalized patients were extracted from the Medical Record Division. Choropleth maps were created to present the geographic distribution of the patients with CVST admitted to our hospital. A total of 145 patients with CVST were included in the study. Etiological factors revealed striking abnormalities in red blood cells counts and serum homocysteine. Analyzing the geographical distribution of the patients with CVST showed most of the patients hailed from Central Karnataka Plateau 106 (73%). Polycythemia was most commonly seen in patients residing in the Central Karnataka Plateau 21 (62%). Conclusion It is inferred that large scale community-based studies to identify a genetic abnormality like a mutant erythropoietin gene should be undertaken to plan effective diagnostic, therapeutic, and preventive measures.

Abstract
This case of recurrent cerebral venous thrombosis (CVT) highlights hyperhomocysteinemia in pernicious anemia due to vitamin B12 deficiency. No other risk factors such as trauma, infections, coagulation disorders or autoimmune diseases were present. The patient was cured with vitamin B12 and anticoagulation therapy. So, it is worthwhile and important to investigate levels of vitamin B12 and homocysteine in CVT.

Abstract
Approximately 7%-12% of all intracranial meningiomas are located in the posterior fossa (PF), a region which contains-among many other critical neurovascular structures-numerous major veins and sinuses draining blood away from the PF structures. There is a growing body of evidence indicating that venous sacrifice or injury during surgery are linked to serious postoperative complications-which may lead to significant morbidity and mortality. Thus, it is of paramount importance that clinicians charged with the preoperative, surgical, and postoperative care of patients undergoing treatment for meningioma are familiar with the general anatomy of the PF veins, as well as their structural nuances and drainage variations. The present chapter surveys the relevant anatomy in a manner that aims to be useful for an interdisciplinary team of clinicians and concludes with a discussion of emerging imaging technologies that may assist them in their clinical decision-making.

Abstract
Cerebral venous sinus thrombosis (CVT) is notoriously known for its varied presentations and extremely high risk of mortality, if remains undetected and untreated. On the other hand, life can be saved with full functional recovery if CVT can be identified with high index of clinical suspicion with supportive imaging and treatment with appropriate anticoagulation. It is important for clinicians to be meticulous to screen for both the potential reversible and heritable causes of CVT so that appropriate measures can be taken to prevent such catastrophe. Here we report a case of CVT involving right sigmoid and transverse sinuses presenting with acute onset left sided hemiplegic without antecedent headache or seizures. Patient was successfully treated with anticoagulants with nearly full functional recovery. Multiple predisposing factors were identified. As per our knowledge, this is the first case of CVT with underlying conglomeration of multiple acquired (lactation, folate deficiency, hyperhomocysteinemia, depot medroxyprogesterone acetate injection) and hereditary risk factors (deficiency of protein C, protein S and antithrombin-III) in a single patient.

Abstract
Cerebral venous sinus thrombosis (CVST) is a relatively rare condition. We present a case of an acute aseptic thrombosis of the sagittal, transverse and sigmoid sinus in a puerperium patient with protein S deficiency. The specifics of the case include high intracranial pressure (ICP) caused by sinus thrombosis with typical symptomatology and bilateral papilloedema, which also manifested in transient bilateral abducens nerve palsy and, consequently, bilateral horizontal diplopia. The recovery of the cranial nerve function occurred 3 to 4 weeks after it was initially reported. Prompt and adequate anticoagulant therapy contributed to the almost complete recanalization of the dural venous sinus thrombosis and a positive outcome of the disease.

Abstract
Introduction Cerebral venous thrombosis is relatively rare and characterized by a wide spectrum of clinical features. It is more common in young adults with women affected more than men. The diagnosis of cerebral venous thrombosis is easier nowadays due to easy access to advanced neuroimaging techniques. Abnormalities in thrombophilic profile are associated with enhanced risk of cerebral venous thrombosis. It has varied etiologies such as hypercoagulable states, infection, dehydration, pregnancy, and substance abuse. Hyperhomocysteinemia is found to be closely associated with an enhanced risk of cerebral venous thrombosis. Case presentation Here we report a case of cerebral venous thrombosis secondary to hyperhomocysteinemia caused by vitamin B12 deficiency in a 32-year-old Indo-Aryan man. A detailed coagulation workup led us to find the etiology of cerebral venous thrombosis in this patient who followed a strict vegetarian diet and had vitamin B12 deficiency leading to hyperhomocysteinemia. Conclusion There are conflicting reports in the literature about the association of hyperhomocysteinemia, B12 deficiency, and cerebral venous thrombosis but some reports point to a significant association. We conclude that further studies with a large sample size are required to analyze the effect of hyperhomocysteinemia and low vitamin B12 on the risk of cerebral venous thrombosis.

Abstract
Many conflicting issues exist about seizure in the setting of cerebral venous and sinus thrombosis (CVST). In this article we aimed to address the existing data regarding incidence, characteristics, predictors, treatment, and prognosis of acute and late seizures in patients with CVST and to prepare more practical information for clinicians. PubMed, Embase, Web of science and Cochrane databases were searched within 1966–2016 using relevant keywords. A total of 63 papers met the inclusion criteria. Seizures are classified as acute symptomatic seizures (ASS; first 14 days) and post‐CVST epilepsy (PCE; after 14 days). The incidence had been reported in a wide range of 6.9–76% for ASS and 4–16% for PCE. Focal and generalized seizures were observed with different predominance. ASS commonly occurred in patients with loss of consciousness, focal neurological deficits, supratentorial lesions and thrombosis in superior sagittal sinus, straight sinus, and cortical veins. PCE had been predisposed by occurrence of ASS, motor deficit, and supratentorial lesions, particularly hemorrhage. Most experts believe that primary prophylaxis with antiepileptic drugs in the acute phase is not indicated. However, the initiation of prophylaxis after the first seizure in patients with supratentorial lesions or focal neurological deficit should be recommended. The quality of current evidence is low and most conclusions are based on expert opinions. More accurate reports of seizure semiology, detailed antiepileptic treatment plans, and outcomes are necessary to answer the existing questions.

Abstract
BACKGROUND Cortical venous thrombosis (CVT) is a rare condition, compared to arterial stroke and often occurs in young individuals presenting with varying clinical features. AIM The aim is to study clinical profile and assess the outcome and prognostic factors of CVT patients. METHODOLOGY A case series study was done for 2 years. CVT cases confirmed by magnetic resonance imaging were included in this study. Clinical presentation and risk factors were noted then patients were assessed at the time of discharge for their physical and mental status. Modified Rankin scale was used to group patients, accordingly scores 0-2 were considered as good and 3-6 as poor outcome, respectively. Data were analyzed using Chi-square test to know the association between prognostic factors and outcome. RESULTS Out of 81 patients, more than half of the patients were in the age group of <35 years (55.6%), and majority of patients were females (79%). Most common symptom was headache (82.7%) and least was fever (14.8%). Superior sagittal sinus was most commonly involved (74.1%). Nearly half of the patients were in puerperal period (44.1%). Patients aged more than 35 years (odds ratio [OR]: 9.1, confidence interval [CI]: 4.463-19.750) presenting with symptoms such as fever (OR: 3.442, CI: 1.088-12.140), impaired consciousness (OR: 5.467, CI: 2.064-15.330) and having clinical signs such as coma (OR: 23.99, CI, 3.844-544.1), papilledema (OR: 25.15, CI: 7.565-101.5), and with focal neurological deficit (OR: 9.366, CI: 2.693-3.41) had statistically significant poor outcome. CONCLUSION Females formed a major bulk of patients. Higher number patients showed poor outcome. Study showed association between age, headache, impaired consciousness, coma, papilledema, and neurological deficit to poor outcome.

Abstract
Objective Cerebral venous sinus thrombosis (CVST) is a rare cerebrovascular disease affecting young adults. The majority of the patients are female. The aim of this study is to assess the clinical associations, risk factors and outcomes of the patients with CVST. Methods The data of 75 patients with CVST admitted to our hospital between 2006 and 2016 were reviewed. Demographic and clinical features and the thrombophilic risk factors of the patients were recorded. The localizations of the thrombi were determined and modified Rankin score at the time of onset and discharge were calculated. Results The majority of our patients (78.7%) were female. Median age was 35 years (16-76). The most common symptom was headache (86.7%). In 82.6% of our patients, inherited or acquired risk factors for thrombosis were detected. Transverse sinus was the most common site of thrombosis followed by sigmoid and superior sagittal sinuses. Two thirds of the patients had involvement of multiple sinuses. The patients with the involvement of sagittal sinus had better disability at the time of admittance ( p = 0.013) while the number of involved sinuses was correlated worse disability ( p = 0.015). The neurologic states in the majority of the patients were improved by the end of the hospitalization period ( p = 0.001). There was no significant difference in disability score at discharge between men and women ( p = 0.080). No patient with CVST died in the hospitalization period. Conclusions This study is one of the largest cohort studies on CVST in our region. The results of the study disclosed that CVST had wide range of clinical manifestations and non-specific symptoms at the beginning. For that reason, in especially high risk groups for thrombosis, the diagnosis of CVST should be kept in mind.

Abstract
Objective Cerebral venous thrombosis (CVT) is a rare condition for which few clinical reviews have been conducted in Korea. Our aim was to investigate, risk factors, clinical presentations/courses, and outcomes of 22 patients treated for CVT at two centers. Materials and Methods A retrospective analysis was conducted, selecting 22 patients diagnosed with and treated for CVT at two patient care centers over a 10-year period (January 1, 2004 to August 31, 2015). Patient data, pathogenetic concerns (laboratory findings), risk factors, locations, symptoms, treatments, and clinical outcomes were reviewed. Results Mean patient age at diagnosis was 54.41 ± 16.19. Patients most often presented with headache (40%), followed by seizure (27%) and altered mental status (18%). Focal motor deficits (5%), visual symptoms (5%), and dysarthria (5%) were less common. Important predisposing factors in CVT included prothrombotic conditions (35%), infections (14%), hyperthyroidism (18%), trauma (14%), and malignancy (4%). By location, 9 patients (40%) experienced thrombosis of superior sagittal sinus predominantly, with involvement of transverse sinus in 20 (90%), sigmoid sinus in 12 (40%), and the deep venous system in 5 (23%). Treatment generally consisted of anticoagulants (63%) or antiplatelet (23%) drugs, but surgical decompression was considered if warranted (14%). Medical therapy in CVT yields good functional outcomes. Conclusion Mean age of patients with CVT in our study exceeded that reported in Europe or in America and had difference in risk factors. Functional outcomes are good with use of antithrombotic medication, whether or not hemorrhagic infarction is evident.

Abstract
BACKGROUND Cerebral venous thrombosis (CVT) is a very uncommon disorder with a wide variety of clinical manifestations. There are few studies describing the clinical and epidemiological profile of CVT in peripheral or rural areas. Over the last decades, the frequency in which this disease is diagnosed has increased due to greater awareness and availability of noninvasive diagnostic techniques. MATERIALS AND METHODS A hospital-based retrospective case review of adult (≥15 years) patients with CVT between 2001 and 2012 is described. 31 patients with confirmed imagiological diagnosis of CVT were included. STATISTICAL ANALYSIS USED Statistical analysis was performed using R version 2.15.2. Incidence rate was computed as number of new cases by time. Confidence interval (CI) was set at 95% and P < 0.05 was considered significant. RESULTS The average annual incidence was 0.84 (CI: 0.58-1.18) to 0.73 (CI: 0.5-1.02) per 100 000 cases for adult population. There were 23 (74%) women and 8 (26%) men. Predominant initial manifestations were headache, followed by altered mental status and seizures. Median diagnostic delay from onset of illness was 8 days. All patients were treated with unfractionated heparin or low-molecular heparin followed by warfarin. Complete recovery occurred in the majority of cases 22 (78.6%) but two patients died during hospitalization. CONCLUSIONS Albeit with some particularities, the epidemiology and clinical manifestations we found are comparable to what has been reported in western studies.

Abstract
PURPOSE OF REVIEW Pediatric venous thromboembolism (VTE) can affect children of all ages, requiring considerable pharmacologic intervention and is often associated with significant morbidity. Current research efforts are directed toward the development of risk-stratified VTE prevention strategies employing pharmacologic thromboprophylaxis, the optimization of conventional anticoagulation, and the investigation of the safety and efficacy of target-specific oral anticoagulants (TSOACs) in children. RECENT FINDINGS Recent research has considerably improved the understanding of risk factors of hospital-acquired VTE and how these factors may be employed in risk-stratified paradigms for VTE prevention in children. Additional insight has been gained in the optimization of conventional anticoagulants in special populations such as neonates and children with inflammatory conditions, and in improving the overall safety and compliance with periprocedural anticoagulation and the use of home International Normalized Ratio monitoring. Furthermore, the use of TSOACs has been described in children and is the focus of numerous ongoing clinical trials that are evaluating the safety and efficacy of these agents in children with VTE. SUMMARY Identification of hospital-acquired VTE risk factors may inform pediatric VTE prevention strategies. Although initial use of TSOACs may be promising, investigation of safety and efficacy in children is still underway.
