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.

Meta-Analysis
To determine the effect of Trendelenburg position on the diameter or cross-section area of the internal jugular vein (IJV) a systematic review and metanalysis was performed. Studies that evaluated the cross-sectional area (CSA) and anteroposterior (AP) diameter of the right internal jugular vein (RIJV) with ultrasonography in supine and any degree of head-down tilt (Trendelenburg position) were analyzed. A total of 22 articles (613 study subjects) were included. A >5° Trendelenburg position statistically increases RIJV CSA and AP diameter. Further inclination from 10° does not statistically benefit IJV size. This position should be recommended for CVC placement, when patient conditions allow it, and US-guided cannulation is not available.

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
OBJECTIVES
Internal jugular vein phlebectasia (IJVP) is a rare type of vascular abnormality that causes dilatation of internal jugular vein in the neck. There is presently no consensus on the most effective method of treatment for this condition, that is commonly seen in children. We conducted a systematic review of the literature reported till date to comprehend the key features of IJVP and its most effective therapeutic modalities.
METHODS
Five databases were searched until October 10, 2022 for articles of any design (including case reports) reporting IJVP in pediatric subjects. Individual patient data on demographics, clinical features of this entity and the differential diagnosis, methods of imaging, management, and outcome of illness were recorded. The quality assessment was performed using the Joanna Briggs Institute's Critical Appraisal Checklist for studies.
RESULTS
A total of 51 articles including 169 cases were retrieved and included in the analysis. Of the 169 patients, most of them were male children, and in 77% of cases right internal Juglar vein was involved. All patients had some symptoms suggestive of IJVP with most common ones being neck swelling or tenderness, and difficulty in breathing. In 90% of cases, it was observed that the neck swelling typically increases in size with Valsalva maneuver. Once jugular vein phlebectasia was clinically suspected, ultrasonography, CECT, or color Doppler flow imaging were used to confirm the diagnosis. The management of most of the cases was either conservative or surgical, and in surgery mostly ligation was performed. There have not been any cases of serious complications, therefore, according to included studies, a conservative approach is recommended with continuous monitoring. Out of the 51 studies included, most of them had low risk of bias.
CONCLUSION
Internal jugular vein phlebectasia, a rare benign condition, is most commonly found in children, and affects predominantly the right internal jugular vein. Although most patients did well with merely conservative treatment, still management of this vascular anomaly has to be on a case-by-case basis.

Meta-Analysis Review
BACKGROUND
Central venous catheters (CVCs) can help with diagnosis and treatment of the critically ill. The catheter may be placed in a large vein in the neck (internal jugular vein), upper chest (subclavian vein) or groin (femoral vein). Whilst this is beneficial overall, inserting the catheter risks arterial puncture and other complications and should be performed with as few attempts as possible. Traditionally, anatomical 'landmarks' on the body surface were used to find the correct place in which to insert catheters, but ultrasound imaging is now available. A Doppler mode is sometimes used to supplement plain 'two-dimensional' ultrasound.
OBJECTIVES
The primary objective of this review was to evaluate the effectiveness and safety of two-dimensional (imaging ultrasound (US) or ultrasound Doppler (USD)) guided puncture techniques for insertion of central venous catheters via the internal jugular vein in adults and children. We assessed whether there was a difference in complication rates between traditional landmark-guided and any ultrasound-guided central vein puncture.Our secondary objectives were to assess whether the effect differs between US and USD; whether the effect differs between ultrasound used throughout the puncture ('direct') and ultrasound used only to identify and mark the vein before the start of the puncture procedure (indirect'); and whether the effect differs between different groups of patients or between different levels of experience among those inserting the catheters.
SEARCH METHODS
We searched the Central Register of Controlled Trials (CENTRAL) (2013, Issue 1), MEDLINE (1966 to 15 January 2013), EMBASE (1966 to 15 January 2013), the Cumulative Index to Nursing and Allied Health Literature (CINAHL) (1982 to 15 January 2013 ), reference lists of articles, 'grey literature' and dissertations. An additional handsearch focused on intensive care and anaesthesia journals and abstracts and proceedings of scientific meetings. We attempted to identify unpublished or ongoing studies by contacting companies and experts in the field, and we searched trial registers. We reran the search in August 2014. We will deal with identified studies of interest when we update the review.
SELECTION CRITERIA
We included randomized and quasi-randomized controlled trials comparing two-dimensional ultrasound or Doppler ultrasound with an anatomical 'landmark' technique during insertion of internal jugular venous catheters in both adults and children.
DATA COLLECTION AND ANALYSIS
Three review authors independently extracted data on methodological quality, participants, interventions and outcomes of interest using a standardized form. A priori, we aimed to perform subgroup analyses, when possible, for adults and children, and for experienced operators and inexperienced operators.
MAIN RESULTS
Of 735 identified citations, 35 studies enrolling 5108 participants fulfilled the inclusion criteria. The quality of evidence was very low for most of the outcomes and was moderate at best for four of the outcomes. Most trials had an unclear risk of bias across the six domains, and heterogeneity among the studies was significant.Use of two-dimensional ultrasound reduced the rate of total complications overall by 71% (14 trials, 2406 participants, risk ratio (RR) 0.29, 95% confidence interval (CI) 0.17 to 0.52; P value < 0.0001, I² = 57%), and the number of participants with an inadvertent arterial puncture by 72% (22 trials, 4388 participants, RR 0.28, 95% CI 0.18 to 0.44; P value < 0.00001, I² = 35%). Overall success rates were modestly increased in all groups combined at 12% (23 trials, 4340 participants, RR 1.12, 95% CI 1.08 to 1.17; P value < 0.00001, I² = 85%), and similar benefit was noted across all subgroups. The number of attempts needed for successful cannulation was decreased overall (16 trials, 3302 participants, mean difference (MD) -1.19 attempts, 95% CI -1.45 to -0.92; P value < 0.00001, I² = 96%) and in all subgroups. Use of two-dimensional ultrasound increased the chance of success at the first attempt by 57% (18 trials, 2681 participants, RR 1.57, 95% CI 1.36 to 1.82; P value < 0.00001, I² = 82%) and reduced the chance of haematoma formation (overall reduction 73%, 13 trials, 3233 participants, RR 0.27, 95% CI 0.13 to 0.55; P value 0.0004, I² = 54%). Use of two-dimensional ultrasound decreased the time to successful cannulation by 30.52 seconds (MD -30.52 seconds, 95% CI -55.21 to -5.82; P value 0.02, I² = 97%). Additional data are available to support use of ultrasound during, not simply before, line insertion.Use of Doppler ultrasound increased the chance of success at the first attempt by 58% (four trials, 199 participants, RR 1.58, 95% CI 1.02 to 2.43; P value 0.04, I² = 57%). No evidence showed a difference for the total numbers of perioperative and postoperative complications/adverse events (three trials, 93 participants, RR 0.52, 95% CI 0.16 to 1.71; P value 0.28), the overall success rate (seven trials, 289 participants, RR 1.09, 95% CI 0.95 to 1.25; P value 0.20), the total number of attempts until success (two trials, 69 participants, MD -0.63, 95% CI -1.92 to 0.66; P value 0.34), the overall number of participants with an arterial puncture (six trials, 213 participants, RR 0.61, 95% CI 0.21 to 1.73; P value 0.35) and time to successful cannulation (five trials, 214 participants, each using a different definition for this outcome; MD 62.04 seconds, 95% CI -13.47 to 137.55; P value 0.11) when Doppler ultrasound was used. It was not possible to perform analyses for the other outcomes because they were reported in only one trial.
AUTHORS' CONCLUSIONS
Based on available data, we conclude that two-dimensional ultrasound offers gains in safety and quality when compared with an anatomical landmark technique. Because of missing data, we did not compare effects with experienced versus inexperienced operators for all outcomes (arterial puncture, haematoma formation, other complications, success with attempt number one), and so the relative utility of ultrasound in these groups remains unclear and no data are available on use of this technique in patients at high risk of complications. The results for Doppler ultrasound techniques versus anatomical landmark techniques are also uncertain.

INTRODUCTION
Aneurysms of the jugular vein system are rare and high clinical suspicion is needed for diagnosis. External jugular vein aneurysms (EJVA) are considered innocent lesions that need treatment mainly for aesthetic reasons. The aim of this systematic review was to present current literature regarding diagnosis and management of EJVAs.
METHODS
A literature review was conducted through the Pubmed/Medline and Scopus regarding articles referring on EJVA from 2000 to 2020. Using the PRISMA guidelines (Preferred Reporting Items for Systematic reviews and Meta-Analyses), 30 articles were identified, according to inclusion criteria. Demographics, clinical characteristics, etiology, diagnostic imaging, complications, treatment, and histopathological findings were recorded and analyzed.
RESULTS
Twenty-seven case reports and one case series were identified, including 30 patients and 31 EJVAs. One-third of patients (30.3%) were < 18 years old (mean age 32 years, range 1-72 years) and 54% of them were females. In 51% of the cases, the lesion was characterized as a true aneurysm after histological evaluation. The presence of a soft cervical mass was the most common clinical symptom, while Valsalva maneuver pointed out the presence of an EJVA in 66.7% of patients. Diagnosis was achieved using ultrasonography, computed tomography, or magnetic resonance imaging. Forty-three percent of the patients underwent more than one radiological examination. Twenty patients underwent surgical management. The primary indication of surgical treatment was aesthetic reasons (11/20, 55%). Thrombosis was the most common EJVA complication (11/30, 36.3%).
CONCLUSIONS
Differential diagnosis of neck mass should include EJVA. High clinical suspicion and adequate imaging are important for diagnosis. Open surgical approach is the more commonly applied therapeutic strategy.

Meta-Analysis
BACKGROUND
Totally implantable venous access port (TIVAP) is a completely closed intravenous infusion system that stays in the human body for a long time. It is used for the infusion of strong irritating or hyperosmotic drugs, nutritional support treatment, blood transfusion and blood specimen collection, and other purposes. There are two common ways of TIVAP: internal jugular vein implantation and subclavian vein implantation. However, the postoperative complications of the two implantation methods are quite different, and there is no recommended implantation method in the relevant guidelines. Therefore, we conducted a meta-analysis to evaluate the difference in complications of the two implantation methods, and choose the better implantation method.
METHODS
Computer search in PubMed, Embase, Web of Science, and Cochrane Library database was conducted for randomized controlled trials (RCTs) from the establishment of the database to October 2021. Two researchers independently screened the literature according to the inclusion and exclusion criteria, extracted data, and evaluated the risk of bias in the included studies. RevMan5.4 software was used for meta-analysis.
RESULTS
A total of 1086 patients in five studies were finally included. The results of meta-analysis showed that there was no significant difference in the incidence of infection (RR = 0.80, 95% CI: 0.43-1.48, = .47), catheter blockage (RR = 0.72, 95% CI: 0.15-3.46, = .68), port squeeze (RR = 1.07, 95% CI: 0.14-8.02, = .95), catheter-related thrombosis (RR = 0.86, 95% CI: 0.22-3.38, = 0.83), catheter displacement (RR = 0.50, 95% CI: 0.22-1.12, = .09), extravasation (RR = 0.12, 95% CI: 0.01-2.15, = .15), and catheter rupture (RR = 3.77, 95% CI: 0.16-89.76, = .41) between the two implantation paths.
CONCLUSIONS
There is little difference in the complication rate of TIVAP between internal jugular vein insertion and subclavian vein insertion. Due to the small number of included studies, there are certain limitations, and more studies need to be included for analysis in the future.

Meta-Analysis Review
BACKGROUND
Central venous catheters can help with diagnosis and treatment of the critically ill. The catheter may be placed in a large vein in the neck (internal jugular vein), upper chest (subclavian vein) or groin (femoral vein). Whilst this is beneficial overall, inserting the catheter risks arterial puncture and other complications and should be performed in as few attempts as possible.In the past, anatomical 'landmarks' on the body surface were used to find the correct place to insert these catheters, but ultrasound imaging is now available.

OBJECTIVES
The primary objective of this review was to evaluate the effectiveness and safety of two-dimensional ultrasound (US)- or Doppler ultrasound (USD)-guided puncture techniques for subclavian vein, axillary vein and femoral vein puncture during central venous catheter insertion in adults and children. We assessed whether there was a difference in complication rates between traditional landmark-guided and any ultrasound-guided central vein puncture.When possible, we also assessed the following secondary objectives: whether a possible difference could be verified with use of the US technique versus the USD technique; whether there was a difference between using ultrasound throughout the puncture ('direct') and using it only to identify and mark the vein before starting the puncture procedure ('indirect'); and whether these possible differences might be evident in different groups of patients or with different levels of experience among those inserting the catheters.
SEARCH METHODS

SELECTION CRITERIA
Randomized and quasi-randomized controlled trials comparing two-dimensional ultrasound or Doppler ultrasound versus an anatomical 'landmark' technique during insertion of subclavian or femoral venous catheters in both adults and children.
DATA COLLECTION AND ANALYSIS
Three review authors independently extracted data on methodological quality, participants, interventions and outcomes of interest using a standardized form. We performed a priori subgroup analyses.
MAIN RESULTS
Altogether 13 studies enrolling 2341 participants (and involving 2360 procedures) fulfilled the inclusion criteria. The quality of evidence was very low (subclavian vein N = 3) or low (subclavian vein N = 4, femoral vein N = 2) for most outcomes, moderate for one outcome (femoral vein) and high at best for two outcomes (subclavian vein N = 1, femoral vein N = 1). Most of the trials had unclear risk of bias across the six domains, and heterogeneity among the studies was significant.For the subclavian vein (nine studies, 2030 participants, 2049 procedures), two-dimensional ultrasound reduced the risk of inadvertent arterial puncture (three trials, 498 participants, risk ratio (RR) 0.21, 95% confidence interval (CI) 0.06 to 0.82; P value 0.02, I² = 0%) and haematoma formation (three trials, 498 participants, RR 0.26, 95% CI 0.09 to 0.76; P value 0.01, I² = 0%). No evidence was found of a difference in total or other complications (together, US, USD), overall (together, US, USD), number of attempts until success (US) or first-time (US) success rates or time taken to insert the catheter (US).For the femoral vein, fewer data were available for analysis (four studies, 311 participants, 311 procedures). No evidence was found of a difference in inadvertent arterial puncture or other complications. However, success on the first attempt was more likely with ultrasound (three trials, 224 participants, RR 1.73, 95% CI 1.34 to 2.22; P value < 0.0001, I² = 31%), and a small increase in the overall success rate was noted (RR 1.11, 95% CI 1.00 to 1.23; P value 0.06, I² = 50%). No data on mortality or participant-reported outcomes were provided.
AUTHORS' CONCLUSIONS
On the basis of available data, we conclude that two-dimensional ultrasound offers small gains in safety and quality when compared with an anatomical landmark technique for subclavian (arterial puncture, haematoma formation) or femoral vein (success on the first attempt) cannulation for central vein catheterization. Data on insertion by inexperienced or experienced users, or on patients at high risk for complications, are lacking. The results for Doppler ultrasound techniques versus anatomical landmark techniques are uncertain.

Meta-Analysis
The relationship between the spinal accessory nerve and internal jugular vein is important for modified neck dissection surgery. Therefore, the aim of this review was to investigate variations in this relationship. Through a search of the PubMed, Scopus, Web of Science, LILACS, and SciELO databases, the review authors collected anatomical data for inclusion in a meta-analysis, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Four relationship patterns were identified and classified: type 1, the nerve lies superficial to the vein; type 2, the nerve lies deep to the vein; type 3, the nerve crosses the branches of the vein; type 4, the nerve splits and its branches pass around the vein. The last pattern was not included in the meta-analysis. Eighteen studies were included (useful sample of 1491 hemi-necks). Type 1 variation had a prevalence of 79.7% (95% CI 77.6-81.7%), type 2 had a prevalence of 19.6% (95% CI 17.7-21.7%), and the type 3 had a prevalence of 0.7% (95% CI 0.0-1.4%). Significant differences were found among geographical subgroups. Normally, the spinal accessory nerve passes superficial to the internal jugular vein, but anatomical variations are common and there is a geographical influence. These findings are important for the safety of modified radical neck dissections.

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.
