OBJECTIVE
Whereas the internal jugular vein is the most common site of thrombosis in patients with deep venous thrombosis (DVT) of the upper extremity, the association between internal jugular vein thrombus and pulmonary embolism (PE) has not been clearly characterized. The objective of this paper was to determine the risk of embolization of an isolated internal jugular vein thrombus causing a clinically overt PE, with the secondary objective of assessing the value of therapeutic anticoagulation in patients with isolated internal jugular vein thrombosis (IJVT) in improving clinical outcomes.
METHODS
The National Center for Biotechnology Information, Cochrane Library, Web of Science, and Cumulative Index to Nursing and Allied Health Literature were searched for articles. The relevant articles included were selected according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Studies were included if they specifically examined incidence of IJVT and incidence of PE and were excluded if they did not report on these rates specifically or failed to specify the exact site of upper extremity DVT.
RESULTS
Of the 274 articles screened, 25 were selected for full review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses inclusion criteria. Seven of those provided adequate data and were included in the review. There were only two studies demonstrating IJVT before PE that could probably establish causality, but this might be confounded by the presence of concomitant upper extremity DVT in one of the cases and radiologic findings compatible with resolving PE in another that might have preceded the presence of internal jugular vein thrombus. In the patients who were found to have PE in the setting of IJVT, the overall observed mortality attributed to PE was low. In specific studies, the use of anticoagulation did not reduce the mortality in those with isolated IJVT or affect the rate of thrombus resolution while carrying the risk of bleeding complications in these patients, who often have severe comorbidities.
CONCLUSIONS
Despite the proximity of the jugular vein to the right side of the heart and the pulmonary vasculature, there is little proof of propagation of the thrombus to cause a clinically overt PE. Whereas current practice is to treat the patients with IJVT in the same way as patients with lower extremity DVTs are treated, the lack of any survival benefit in those with isolated IJVT and the risk of bleeding complications warrant further studies to characterize the need of medical management in this population of patients.

World Journal of Clinical Cases Jul 2021Portal vein thrombosis (PVT) was previously a contraindication for trans-jugular intrahepatic portosystemic shunt (TIPS).
BACKGROUND
Portal vein thrombosis (PVT) was previously a contraindication for trans-jugular intrahepatic portosystemic shunt (TIPS).
AIM
To perform a systematic review and meta-analysis of the current available studies investigating outcomes of TIPS for cirrhotic patient with PVT.
METHODS
Multiple databases were systematically searched to identify studies investigating the outcomes of TIPS for cirrhotic patients with PVT. The quality of studies was assessed by Cochrane Collaboration method and Methodological Index for Non-Randomized Studies. The demographic data, outcomes, combined treatment, and anticoagulation strategy were extracted.
RESULTS
Twelve studies were identified with 460 patients enrolled in the analysis. The technical success rate was 98.9% in patients without portal vein cavernous transformation and 92.3% in patients with portal vein cavernous transformation. One-year portal vein recanalization rate was 77.7%, and TIPS patency rate was 84.2%. The cumulative encephalopathy rate was 16.4%. One-year overall survival was 87.4%.
CONCLUSION
TIPS is indicated for portal hypertension related complications and the restoration of pre-transplantation portal vein patency in cirrhotic patients with PVT. Cavernous transformation is an indicator for technical failure. Post-TIPS anticoagulation seems not mandatory. Simultaneous TIPS and percutaneous mechanical thrombectomy device could achieve accelerated portal vein recanalization and decreased thrombolysis-associated complications, but further investigation is still needed.

Review
Autologous fillet flaps are a common reconstructive option for large defects after forequarter amputation (FQA) due to advanced local malignancy or trauma. The inclusion of osseous structures into these has several advantages. This article therefore systematically reviews reconstructive options after FQA, using osteomusculocutaneous fillet flaps, with emphasis on personalized surgical technique and outcome. Additionally, we report on a case with an alternative surgical technique, which included targeted muscle reinnervation (TMR) of the flap. Our literature search was conducted in the PubMed and Cochrane databases. Studies that were identified were thoroughly scrutinized with regard to relevance, resulting in the inclusion of four studies (10 cases). FQA was predominantly a consequence of local malignancy. For vascular supply, the brachial artery was predominantly anastomosed to the subclavian artery and the brachial or cephalic vein to the subclavian or external jugular vein. Furthermore, we report on a case of a large osteosarcoma of the humerus. Extended FQA required the use of the forearm for defect coverage and shoulder contour reconstruction. Moreover, we performed TMR. Follow-up showed a satisfactory result and no phantom limb pain. In case of the need for free flap reconstruction after FQA, this review demonstrates the safety and advantage of osteomusculocutaneous fillet flaps. If the inclusion of the elbow joint into the flap is not possible, we recommend the use of the forearm, as described. Additionally, we advocate for the additional implementation of TMR, as it can be performed quickly and is likely to reduce phantom limb and neuroma pain.

Introduction Treatment of cranial neurovascular pathology requires a detailed understanding of the brain, head, and neck vasculature. This study aims at a comprehensive overview of the microsurgical anatomy of the anterior cerebral circulation. Methods Five formalin-fixed adult cadaveric heads were used. Common carotid arteries, vertebral arteries, and internal jugular veins were injected with colored latex (red for arteries and blue for veins). The heads were dissected under a surgical microscope with magnifications ranging between 3× to 40× focusing on the anterior circulation. A synoptic approach was used to describe in detail the segments, branches, perforating arteries, veins, and vascular territories of the cerebral arteries and veins. Results The anterior arterial circulation of the brain is provided by the internal carotid artery (ICA), anterior cerebral artery (ACA), middle cerebral artery (MCA), anterior communicating artery (ACoA), and perforating arteries. Perforating arteries of the anterior circulation arise from the ICA, ACA, MCA, ACoA, and posterior communicating artery (PCoA). The distal segments and collateral branches of the ICA, ACA, and MCA give the arterial supply to the largest part of the forebrain, whereas perforating arteries of the anterior circulation are related to the striatum, thalamus, and basal ganglia. The ACoA is the core functional anastomosis between the left and right ICA systems. The external carotid artery provides the vascular supply to the region of the face, head, and neck, and most of the meninges. The internal jugular venous system is composed of the internal and external jugular veins, which constitutes the outflow of the cerebral and facial venous system, respectively. Conclusion Thorough knowledge of the topographic, cisternal, and functional anatomy of the anterior circulation of the brain is critical for surgery of the supratentorial lesions.

Review
NEW FINDINGS
What is the central question of this study? Recently, an internal jugular venous thrombus was identified during spaceflight: does microgravity induce venous and/or coagulation pathophysiology, and thus an increased risk of venous thromboembolism (VTE)? What is the main finding and its importance? Whilst data are limited, this systematic review suggests that microgravity and its analogues may induce an enhanced coagulation state due to venous changes most prominent in the cephalad venous system, as a consequence of changes in venous flow, distension, pressures, endothelial damage and possibly hypercoagulability in microgravity and its analogues. However, whether such changes precipitate an increased VTE risk in spaceflight remains to be determined.
ABSTRACT
Recently, an internal jugular venous thrombus was identified during spaceflight, but whether microgravity induces venous and/or coagulation pathophysiology, and thus, an increased risk of venous thromboembolism (VTE) is unclear. Therefore, a systematic (Cochrane compliant) review was performed of venous system or coagulation parameters in actual spaceflight (microgravity) or ground-based analogues in PubMed, MEDLINE, Ovid EMBASE, Cochrane Library, European Space Agency, National Aeronautics and Space Administration, and Deutsches Zentrum für Luft-und Raumfahrt databases. Seven-hundred and eight articles were retrieved, of which 26 were included for evaluation with 21 evaluating venous, and five coagulation parameters. Nine articles contained spaceflight data, whereas the rest reported ground-based analogue data. There is substantial variability in study design, objectives and outcomes. Yet, data suggested cephalad venous system dilatation, increased venous pressures and decreased/reversed flow in microgravity. Increased fibrinogen levels, presence of thrombin generation markers and endothelial damage were also reported. Limited human venous and coagulation system data exist in spaceflight, or its analogues. Nevertheless, data suggest spaceflight may induce an enhanced coagulation state in the cephalad venous system, as a consequence of changes in venous flow, distension, pressures, endothelial damage and possibly hypercoagulability. Whether such changes precipitate an increased VTE risk in spaceflight remains to be determined.

Diagnostic Accuracy of Ultrasonographic Respiratory Variation in the Inferior Vena Cava, Subclavian Vein, Internal Jugular Vein, and Femoral Vein Diameter to Predict Fluid Responsiveness: A Systematic Review and Meta-Analysis.
This systematic review and meta-analysis aimed to investigate the ultrasonographic variation of the diameter of the inferior vena cava (IVC), internal jugular vein (IJV), subclavian vein (SCV), and femoral vein (FV) to predict fluid responsiveness in critically ill patients. Relevant articles were obtained by searching PubMed, EMBASE, and Cochrane databases (articles up to 21 October 2021). The number of true positives, false positives, false negatives, and true negatives for the index test to predict fluid responsiveness was collected. We used a hierarchical summary receiver operating characteristics model and bivariate model for meta-analysis. Finally, 30 studies comprising 1719 patients were included in this review. The ultrasonographic variation of the IVC showed a pooled sensitivity and specificity of 0.75 and 0.83, respectively. The area under the receiver operating characteristics curve was 0.86. In the subgroup analysis, there was no difference between patients on mechanical ventilation and those breathing spontaneously. In terms of the IJV, SCV, and FV, meta-analysis was not conducted due to the limited number of studies. The ultrasonographic measurement of the variation in diameter of the IVC has a favorable diagnostic accuracy for predicting fluid responsiveness in critically ill patients. However, there was insufficient evidence in terms of the IJV, SCV, and FV.

Meta-Analysis Review
BACKGROUND
Transjugular liver biopsy (TJLB) procedurally samples liver tissue through the internal jugular vein. It is indicated in the presence of coagulopathies and/or ascites.
AIMS
This meta-analysis aimed to assess the safety and efficacy of TJLB in children.
METHODS
A literature search of several databases was conducted from inception to August 2022. Eligible studies reported pediatric patients (< 18 years old) who underwent TJLB. The pooled proportion was analyzed using a random-effects model. This review was registered in PROSPERO (CRD42022354421).
RESULTS
From 921 initial studies screened, eight met the eligibility criteria, with a total of 361 pediatric patients who underwent 374 TJLBs. All eight studies reported pooled rates of technical success at 99.1% (95% CI 0.982, 1.001; I = 0%) and histological adequacy of sampling at 97.5% (95% CI 0.954, 0.995; I = 27.66%). A total of 49 complications were reported across six studies, the most common being bleeding from the entry site (38.78%), fevers for less than 24 h (12.24%), red blood cells transfusion requirement (10.2%), supraventricular tachycardia (8.16%), and pain requiring analgesia (8.16%).
CONCLUSION
Pediatric TJLB demonstrates high rates of technical success and adequate liver core biopsy samples, with a low rate of complications. These results suggest that TJLB is an effective method for diagnostic yield and postprocedural outcomes, especially in patients with preexisting coagulopathies and ascites where percutaneous liver biopsy is contraindicated. Additional studies evaluating larger groups of pediatric patients may provide further support for the use of TJLB in this population.

Review
BACKGROUND
Spontaneous orbital cephaloceles are a rare condition. The purpose of this study is to provide a description of a clinical case and to carry out a systematic literature review.
METHODS
A systematic review of the English literature published on the Pubmed, Scopus, and Web of Science databases was conducted, according to the PRISMA recommendations.
RESULTS
A 6-year-old patient was admitted for right otomastoiditis and thrombosis of the sigmoid and transverse sinuses, as well as the proximal portion of the internal jugular vein. Radiological examinations revealed a left orbital mass (22 × 14 mm) compatible with asymptomatic orbital meningocele (MC) herniated from the superior orbital fissure (SOF). The child underwent a right mastoidectomy. After the development of symptoms and signs of intracranial hypertension (ICH), endovascular thrombectomy and transverse sinus stenting were performed, with improvement of the clinical conditions and reduction of the orbital MC. The systematic literature review encompassed 29 publications on 43 patients with spontaneous orbital MC. In the majority of cases, surgery was the preferred treatment.
CONCLUSIONS
The present case report and systematic review highlight the importance of ICH investigation and a pathophysiological-oriented treatment approach. The experiences described in the literature are limited, making the collection of additional data paramount.

Review
Tuberculous pericarditis (TBP) is an important cause of pericarditis worldwide while being infrequent in childhood, especially in low-TB-incidence countries. We report a case of TBP and provide a systematic review of the literature, conducted by searching PubMed, Scopus, and Cochrane to find cases of TBP in pediatric age published in the English language between the year 1990 and the time of the search. Of the 587 search results obtained, after screening and a backward citation search, 45 studies were selected to be included in this review, accounting for a total of 125 patients. The main signs and symptoms were fever, cough, weight loss, hepatomegaly, dyspnea, and increased jugular venous pressure or jugular vein turgor. A definitive diagnosis of TBP was made in 36 patients, either thanks to microbiological investigations, histological analysis, or both. First-line antitubercular treatment (ATT) was administered in nearly all cases, and 69 children underwent surgical procedures. Only six patients died, and only two died of TBP. TBP in childhood is relatively uncommon, even in high-TB-prevalence countries. Clinical manifestations, often suggestive of right-sided cardiac failure, are subtle, and diagnosis is challenging. TBP has an excellent prognosis in childhood; however, in a significant proportion of cases, invasive surgical procedures are necessary.

INTRODUCTION
Central venous catheterization is a commonly performed procedure, accounting for approximately 8% of hospitalized patients. Based on the current literatures, the most acceptable site for central venous catheterization is inconclusive, considering various complications in hospitalized patients. Herein, we conducted a network meta-analysis to assess the clinically important complications among internal jugular, subclavian, femoral, and peripheral insertion.
MATERIALS AND METHODS
The Cochrane Central Register of Controlled Trials, MEDLINE, Web of Science, Ichushi databases, Clinicaltrials.gov, and International Clinical Trials Registry Platform were searched. Studies including adults aged ≥ 18 years and randomized control trials that compared two different insertion sites (internal jugular, subclavian, femoral, and peripheral vein) were selected. The primary outcomes were clinically important infectious, thrombotic, and mechanical complications.
RESULTS
Among the 5,819 records initially identified, 13 trials (6,201 patients) were included for a network meta-analysis. For clinically important infectious complication, subclavian insertion decreased the complication risk, compared with internal jugular [risk ratio (RR), 0.30; 95% confidence interval (CI), 0.11-0.81; moderate certainty], and femoral insertion increased than subclavian insertion (RR 2.56; 95% CI, 1.02-6.44; moderate certainty). Peripheral insertion was also significantly associated with a lower risk compared with internal jugular (RR 0.06; 95% CI, 0.01-0.32; low certainty); subclavian (RR 0.21; 95% CI, 0.05-0.77; moderate certainty); and femoral insertion (RR 0.08; 95% CI, 0.02-0.40; low certainty). For clinically important thrombotic complication, we did not find significant differences between insertion sites. For clinically important mechanical complication, femoral insertion decreased the complication risk, compared with internal jugular (RR 0.42; 95% CI, 0.21-0.82; moderate certainty) and subclavian insertion (RR 0.33; 95% CI, 0.16-0.66; moderate certainty). Peripheral insertion was also associated with the lower complication risk compared with internal jugular (RR 0.39; 95% CI, 0.18-0.85; low certainty) and subclavian insertion (RR 0.31; 95% CI, 0.13-0.75; moderate certainty).
CONCLUSION
The insertion site of the central venous catheter, which is most likely to cause the fewest complications, should be selected. Our findings can provide the rationale for deciding the insertion site for a central venous catheter.
