Abstract
As the number of pacemaker insertions increases to manage numerous cardiac arrhythmias, the number of complications is also increasing as a result. More common complications such as infection and lead displacement are routinely discussed with patients before they undergo the procedure. However rare complications such as superior vena cava syndrome are not discussed during the consenting period. But they do occur, as seen in this case of a 69-year-old male. This fit and active man had a right-sided dual-chamber pacemaker inserted due to sinus node disease and presented 5 years later with symptoms suggestive of superior vena cava obstruction (SVCO). Despite anticoagulation and before surgical intervention could be performed, the patient developed a right-sided chylothorax which was drained. An autologous pericardial patch repair of the SVC and a thrombectomy of SVC clots was subsequently performed. This was only partially successful and the SVCO recurred. A low fatty chain diet was initiated to manage the chylothorax, which remains stable. This rare complication has left the patient with a small pleural effusion and chronic pleural thickening. They can still exercise with mild breathlessness. The management of such a complication, which requires the input of many specialists, is challenging and often does not completely resolve all symptoms. For this reason, superior vena cava obstruction should be considered as a risk during the consenting procedure for a pacemaker insertion.

Abstract
Background Unusual site deep vein thrombosis (DVT) was defined as venous thromboembolism (VTE) occurring outside the conventional deep veins of the lower extremity or pulmonary arteries. However, the optimal anticoagulation therapy for unusual site DVT remained unclear. This study aims to evaluate the efficacy and safety of rivaroxaban in unusual site DVT. Methods This retrospective cohort study enrolled consecutive patients at Nanjing Drum Tower Hospital between January 2011 and December 2021 who were diagnosed with unusual site DVT. Patients were divided into two groups based on their ultimate medication choice: the warfarin group and the rivaroxaban group. The demographic characteristics were recorded for all enrolled patients. Clinical outcomes included recurrent VTE, bleeding complications and major bleeding. Results A total of 1,088 patients were divided into warfarin (n = 514) and rivaroxaban (n = 574) groups. After the stabilized inverse probability of treatment weighting, Hazard Ratios for warfarin vs. rivaroxaban of recurrent VTE, bleeding complications and major bleeding were 0.52(95% CI: 0.25-1.08), 0.30(95% CI: 0.14-0.60), and 0.33 (95% CI, 0.13-0.74), respectively. Risk of clinical outcomes in specified subgroups for age, gender, renal function, thrombosis sites and diagnosis were assessed. The interaction of gender and treatment on major bleeding was significant (P for interaction = 0.062). Otherwise, there was no significant interaction between the other subgroups and the treatment group in terms of clinical outcomes. Conclusion Compared with warfarin, rivaroxaban exhibited comparable efficacy for the anticoagulant treatment of unusual site DVT, associated with a lower risk of bleeding complications and major bleeding.

Abstract
Septic pelvic thrombophlebitis (SPT) is a rare condition that forms thrombosis in the pelvic veins, typically the ovarian veins, with subsequent infection and inflammation. We present a case of right ovarian vein thrombosis (ROVT), methicillin-resistant Staphylococcus aureus (MRSA) bacteremia, and delayed onset of SPT symptoms, requiring tissue-plasminogen activator. A 40-year-old woman, G3P2, at 38 weeks' gestation, was admitted with a fever of 39°C. She had cervical insufficiency and had been often on bed rest. Blood culture revealed MRSA and computed tomography revealed a large ROVT. She received vancomycin and direct oral anticoagulant, and her fever resolved by day 3. On day 16, fever recurred with severe pain over the ROVT. Second computed tomography showed thickening of venous wall with enhancement around ROVT, consistent with SPT. Since pain and fever gradually exacerbated despite treatment with DOAC and antimicrobials, she was started on heparin and tissue plasminogen activator on days 23 and 25, respectively. Along with recanalization on the thrombosis by day 29, fever and abdominal pain resolved. We experienced a case of delayed onset SPT associated with MRSA bacteremia and a large ROVT. MRSA bacteremia might cause the originally existing ROVT to become an infection source, resulting in SPT with recurrent symptoms and long-term treatment. Early and strict anticoagulation is crucial in cases with a large thrombosis and bacteremia, due to the high risk of progression to SPT. This case highlights the importance of recanalization for the treatment of SPT and usefulness of administration of tissue-plasminogen activator for the massive thrombosis.

Abstract
Splanchnic vein thrombosis (SVT), a thrombosis which involves the portal, mesenteric, and splenic veins, and the Budd-Chiari syndrome, represents an uncommon type of venous thromboembolism (VTE). Like with deep vein thrombosis of the lower extremities and pulmonary embolism, ample evidence suggests a significant association between SVT and cancer, particularly intra-abdominal solid malignancies (e.g. hepatobiliary and pancreatic cancers) and myeloproliferative neoplasms (MPN). Clinical symptoms of SVT in cancer patients can be ambiguous, and frequently attributed to the primary cancer itself. Alternatively, SVT may be asymptomatic and detected incidentally during cancer staging or follow-up evaluations. SVT can also precede the diagnosis of cancer and has been associated with poorer outcomes in patients with liver or pancreatic cancers. Therefore, an unprovoked SVT warrants a thorough evaluation for an underlying malignancy or MPN. Cancer-associated SVT carries a high risk of VTE extension, recurrence and bleeding. Extended anticoagulant treatment is often required in the absence of a high bleeding risk. Guidelines suggest treatment with either low molecular weight heparin (LMWH) or direct oral anticoagulants (DOACs), although available data on the safety and effectiveness of DOACs in these patients is limited. This comprehensive review outlines the epidemiology, pathogenesis, risk factors, and diagnosis of cancer-associated SVT and underscores the importance of comprehensive patient evaluation and evidence-based management.

Abstract
BACKGROUND The clinical characteristics of splanchnic vein thrombosis (SVT) in pediatric patients and its optimal treatment strategies are unknown. OBJECTIVES This study aimed to assess the effectiveness and safety of anticoagulant therapy for pediatric SVT. METHODS MEDLINE and EMBASE databases were searched up to December 2021. We included observational and interventional studies that enrolled pediatric patients with SVT and reported anticoagulant treatment and outcomes, including rates of vessel recanalization, SVT extension, venous thromboembolism (VTE) recurrence, major bleeding, and mortality. Pooled proportions of vessel recanalization were calculated with their 95% CI. RESULTS A total of 506 pediatric patients (aged 0-18 years) across 17 observational studies were included. The majority of patients had portal vein thrombosis (n = 308, 60.8%) or Budd-Chiari syndrome (n = 175, 34.6%). Most events were triggered by transient provoking factors. Anticoagulation (heparins and vitamin K antagonists) was prescribed in 217 (42.9%) patients, and 148 (29.2%) patients underwent vascular interventions. The overall pooled proportions of vessel recanalization were 55.3% (95% CI, 34.1%-74.7%; I2 = 74.0%) among anticoagulated patients and 29.4% (95% CI, 2.6%-86.6%; I2 = 49.0%) among non-anticoagulated patients. SVT extension, major bleeding, VTE recurrence, and mortality rates were 8.9%, 3.8%, 3.5%, and 10.0%, respectively, in anticoagulated patients and 2.8%, 1.4%, 0%, and 50.3%, respectively, in non-anticoagulated patients. CONCLUSION In pediatric SVT, anticoagulation appears to be associated with moderate recanalization rates and a low risk of major bleeding. VTE recurrence is low and comparable to that reported in pediatric patients with other types of provoked VTE.

Abstract
Patients with inflammatory bowel disease (IBD), both Crohn's disease and ulcerative colitis, frequently experience venous thromboembolism (VTE), a potentially fatal consequence. The pathophysiological mechanisms contributing to VTE include inflammation, modifications in coagulation factors, endothelial dysfunction, and platelet activation. Numerous pro-inflammatory cytokines and markers, such as tumor necrosis factor-alpha and interleukin-6, have a significant impact on the thrombotic cascade. Patients with IBD are more likely to suffer VTE for a variety of causes. Exacerbations of preexisting conditions, admission to the hospital, surgical intervention, immobilization, corticosteroid usage, central venous catheterization, and hereditary susceptibility all fit into this category. The mainstay of therapy for VTE in IBD patients includes anticoagulation that is individualized for each patient depending on the thrombosis site, severity, bleeding risk, and interaction with other drugs. In some high-risk IBD patients, such as those having major surgery or hospitalized with severe flare, preventive anticoagulation may play a role. However, the acceptance rate for this recommendation is low. Additionally, there is a subset of patients who would require extended thromboprophylaxis. The majority of the studies that looked into this question consisted of patients in the surgical setting. Emerging data suggest that risk factors other than surgery can also dictate the duration of anticoagulation. While extending anticoagulation in all patients may help reduce VTE-related mortality, identifying these risk factors is important. Hence, the decision to initiate prophylaxis should be individualized, considering the overall thrombotic and bleeding risks. This review explores the relationship between IBD and VTE, including risk factors, epidemiology, and prevention. A multifactorial approach involving aggressive management of underlying inflammation, identification of modifiable risk factors, and judicious use of anticoagulant therapy is essential for reducing the burden of VTE in this vulnerable population.

Abstract
A rare case of a 35 years old woman presented with renal arcuate vein thrombosis (RAVT) and acute kidney injury (AKI) following upper respiratory tract symptoms and toxic substance ingestion. Histopathological evaluation of the patient's kidney tissue indicated a rare venous thrombosis in the renal arcuate veins. Anticoagulation with Apixaban, a direct oral anticoagulant (DOAC), was commenced, and the patient's symptoms resolved during the hospital stay. Hitherto, a limited number of studies have shown the concurrent presentation of RAVT and overt AKI in patients following ingestion of nephrotoxic agents. Further studies are necessary to elucidate the etiology, clinical presentation, and treatment of RAVT. We suggest that Apixaban be studied as a suitable alternative to conventionally used anti-coagulants such as Warfarin in patients who lack access to optimal health care facilities.

Abstract
Renal vein thrombosis (RVT) is a rare condition characterized by the formation of a blood clot in one or both of the renal veins. Bilateral involvement is more common, but when the condition affects only one side, it usually occurs on the left due to more extensive venous vasculature compared to the right side. RVT can be caused by various factors such as trauma, dehydration, malignancy, and a hypercoagulable state. Acute RVT is typically more severe than chronic, and it can cause symptoms such as renal infarction, acute kidney injury, renal failure, severe flank pain, and hematuria. Some cases of RVT have also been linked to coronavirus disease 2019 (COVID-19), which is widely recognized to induce a hypercoagulable state. The standard treatment for RVT is warfarin but in this case report, we describe a COVID-19 patient with RVT whose thrombus was successfully treated with direct-acting oral anticoagulant (DOAC) apixaban for six months.

Abstract
SVT is a potentially life-threatening disease associated with a substantial risk of recurrence and bleeding. Rivaroxaban appears to be a reasonable alternative to standard anticoagulation for the treatment of SVT in patients without cirrhosis.
Heparins and vitamin K antagonists are the mainstay of treatment of splanchnic vein thrombosis (SVT). Rivaroxaban is a potential alternative, but data to support its use are limited. We aimed to evaluate the safety and efficacy of rivaroxaban for the treatment of acute SVT. In an international, single-arm clinical trial, adult patients with a first episode of noncirrhotic, symptomatic, objectively diagnosed SVT received rivaroxaban 15 mg twice daily for 3 weeks, followed by 20 mg daily for an intended duration of 3 months. Patients with Budd-Chiari syndrome and those receiving full-dose anticoagulation for >7 days prior to enrollment were excluded. Primary outcome was major bleeding; secondary outcomes included death, recurrent SVT, and complete vein recanalization within 3 months. Patients were followed for a total of 6 months. A total of 103 patients were enrolled; 100 were eligible for the analysis. Mean age was 54.4 years; 64% were men. SVT risk factors included abdominal inflammation/infection (28%), solid cancer (9%), myeloproliferative neoplasms (9%), and hormonal therapy (9%); 43% of cases were unprovoked. JAK2 V617F mutation was detected in 26% of 50 tested patients. At 3 months, 2 patients (2.1%; 95% confidence interval, 0.6-7.2) had major bleeding events (both gastrointestinal). One (1.0%) patient died due to a non–SVT-related cause, 2 had recurrent SVT (2.1%). Complete recanalization was documented in 47.3% of patients. One additional major bleeding event and 1 recurrent SVT occurred at 6 months. Rivaroxaban appears as a potential alternative to standard anticoagulation for the treatment of SVT in non-cirrhotic patients. This trial was registered at www.clinicaltrials.gov as #NCT02627053 and at eudract.ema.europa.eu as #2014-005162-29-36.

Abstract
The term unusual site thrombosis refers to the occurrence of venous thromboembolism outside of the lower limbs and the pulmonary arteries. Unusual site thrombosis can virtually affect any venous segment, with the most common and/or clinically relevant sites including the upper limbs veins, the retinal veins, the splanchnic veins and the cerebral veins. Clinical features are obviously heterogeneous, while many predisposing factors are common, though with different prevalence among the various disorders. Antithrombotic therapy is prescribed to most patients, but the type, intensity, and duration of treatment vary both within and among patient groups. Increasing evidence is supporting the use of the direct oral anticoagulants in patients with upper limb deep vein thrombosis, cerebral vein thrombosis, and with splanchnic vein thrombosis. This article will review available evidence on the treatment of venous thrombosis occurring in unusual sites.

Abstract
Case 1: A 23-year-old female third-year medical student who has no medical history seeks treatment for abdominal distention. She takes an estrogen-containing birth control pill and does not smoke or consume alcohol. Family history is unremarkable. Physical examination is significant for abdominal distention, and an abdominal fluid wave is detected. Complete blood count is normal. Imaging confirms occlusive thrombosis of the main portal vein. On endoscopy, grade 1 to 2 esophageal varices are noted and banded. Unfractionated heparin is begun. Subsequent workup reveals a homozygous factor V Leiden mutation. Long-term anticoagulation is planned, and she asks if warfarin can be avoided given her hectic ward rotations, erratic diet, and need for monitoring. Case 2: A 35-year-old woman who has no medical history seeks treatment for progressively worsening posterior headaches for 1 week. Magnetic resonance imaging of the brain shows dural sinus thrombosis with associated small areas of petechial cerebral hemorrhage. She is started on a continuous unfractionated heparin infusion and admitted to the hospital for further observation. Her grandmother is on warfarin for atrial fibrillation, and the patient would prefer to avoid warfarin because she does not think she can comply with the frequent monitoring that will be required. She inquires about other oral anticoagulant options for her condition.

Diagnostic and treatment recommendations from the FACME ad-hoc expert working group on the management of cerebral venous sinus thrombosis associated with COVID-19 vaccination. NEUROLOGÍA (ENGLISH EDITION) 2021; 36:451-461. [PMID: 34112621 PMCID: PMC8164341 DOI: 10.1016/j.nrleng.2021.05.001] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2021] [Accepted: 05/04/2021] [Indexed: 12/12/2022] Open
Abstract
INTRODUCTION Cases of cerebral venous sinus thrombosis have been reported in individuals vaccinated against COVID-19 with non-replicating adenoviral vector vaccines. We issue our recommendations on the diagnosis and management of patients presenting this complication. METHODS The multidisciplinary working group, led by the Spanish Federation of Medical and Scientific Associations (FACME) and including representatives of several scientific societies, reviewed the available evidence from the literature and reports of the European Medicines Agency. We establish a definition for suspected cases and issue diagnostic and treatment recommendations regarding vaccine-induced immune thrombotic thrombocytopaenia. RESULTS We define suspected cases as those cases of cerebral venous sinus thrombosis occurring between 3 and 21 days after the administration of non-replicating adenoviral vector vaccines, in patients with a platelet count below 150 000/μL or presenting a decrease of 50% with respect to the previous value. Findings suggestive of vaccine-induced immune thrombotic thrombocytopaenia include the presence of antibodies to platelet factor 4, D-dimer levels 4 times greater than the upper limit of normal, and unexplained thrombosis. The recommended treatment includes intravenous administration of non-specific human immunoglobulin or alternatively plasmapheresis, avoiding the use of heparin, instead employing argatroban, bivalirudin, fondaparinux, rivaroxaban, or apixaban for anticoagulation, and avoiding platelet transfusion. CONCLUSIONS Non-replicating adenoviral vector vaccines may be associated with cerebral venous sinus thrombosis with thrombocytopaenia; it is important to treat the dysimmune phenomenon and the cerebral venous sinus thrombosis.

Abstract
Introducción Se han reportado casos de trombosis venosas cerebrales en personas vacunadas frente a COVID-19 con vacunas vectorizadas con adenovirus no replicantes. Aportamos recomendaciones sobre el diagnóstico y manejo de pacientes con esta complicación. Método El grupo de trabajo multidisciplinar, liderado por la Federación de Asociaciones Científico Médicas Españolas y representado por distintas sociedades científicas, revisó la evidencia disponible publicada en la literatura y en los informes de la Agencia Europea de Medicamentos. Se estableció una definición de caso sospechoso y recomendaciones diagnóstico-terapéuticas de la trombocitopenia trombótica inducida por la vacunación. Resultados Se considera caso sospechoso aquella trombosis venosa cerebral ocurrida entre 3 y 21 días tras la administración de vacunas no replicantes de adenovirus que presenten un valor de plaquetas inferior a 150.000 plaquetas por μL o un descenso del 50% respecto de la cifra previa. Los datos indicativos de trombocitopenia trombótica inducida por la vacunación incluyen la presencia de anticuerpos antifactor plaquetario tipo 4, la elevación de dímero-D 4 veces por encima del límite superior de la normalidad o la ausencia de justificación de la trombosis. En su tratamiento, se recomienda administrar inmunoglobulina humana inespecífica intravenosa o realizar plasmaféresis en su defecto, evitar el uso de heparina, empleando como anticoagulantes argatroban, bivalirudina, fondaparinux, rivaroxabán o apixabán, y evitar la transfusión de plaquetas. Conclusiones Las vacunas de vectores no replicantes de adenovirus pueden asociarse a trombosis venosas cerebrales con trombocitopenia, en cuyo manejo es importante el tratamiento del fenómeno disinmune y de la trombosis venosa cerebral.

Abstract
Portal vein thrombosis (PVT) is the most frequent among the splanchnic vein thrombosis, accounting for 90% of cases. More than half of PVT are provoked by liver cirrhosis, solid cancer or myeloproliferative neoplasms. The remaining cases are non-malignant non-cirrhotic PVT and include either unprovoked events or thrombosis secondary to other less common risk factors (e.g. abdominal surgery, intrabdominal inflammations/infections, or hormonal stimuli). Anticoagulant therapy in patients with acute symptomatic PVT should be started early after diagnosis, if no active bleeding, to obtain greater vessel recanalization and reduce the occurrence of portal-hypertension related complications. Gastroesophageal varices do not represent a contraindication to anticoagulant treatment, as long as adequate measures have been undertaken for the prophylaxis of gastroesophageal bleeding. Different treatment options (unfractionated or low molecular weight heparin, vitamin K antagonists and direct oral anticoagulants [DOACs]) can be considered. In this narrative review we will discuss the treatment of PVT in the three most common scenarios (cirrhosis-associated, cancer-associated and non-malignant non-cirrhotic PVT). We will also discuss the role of the DOACs and summarise recent guidelines on this topic.
