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.

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.

Review
BACKGROUND
Multiple Sclerosis (MS) is a complex neurodegenerative condition that is influenced by a combination of genetic and environmental factors. Included in these factors is the venous system, however, the extent to which it influences the etiology of MS has yet to be fully characterised. The aim of this review is to critically summarize the literature available concerning the venous system in MS, primarily concerning specific data on the venous pressure and blood flow in this system.
METHODS
A systematic review was conducted with the application of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria. The advanced search functions of both the Scopus and PubMed databases were used to conduct the literature search, resulting in 136 unique articles initially identified. Applying relevant exclusion criteria, 22 of the studies were chosen for this review.
RESULTS
The selected studies were analysed for venous pressure and blood flow related findings, with 14 studies contributing data on the internal jugular vein (IJV) flow rate, 5 on blood flows of the intracranial venous sinuses, 2 on blood flow pulsatility and 6 supplying information relevant to the venous pressure (3 studies contributed to multiple areas). The general findings of the review included that the IJV flow was not significantly different between MS patients and controls, however, there were variances between stenotic (S) and non-stenotic (NS) MS patients. Due to the limited data in the other two areas defined in this review, further research is required to establish if any variances in MS are present.
CONCLUSION
It remains unclear if there are significant differences in many flow variables between MS patients and controls considered in this review. It would be advantageous if future work in this area focused on understanding the hemodynamics of this system, primarily concerning how the flow rate, venous pressure and vascular resistance are related, and any impact that these factors have on the etiology of MS.

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
BACKGROUND
Few data are available on the use of internal jugular vein (IJV) ultrasound parameters to assess central venous pressure and clinical outcomes among patients with suspected or confirmed heart failure (HF).
METHODS
We performed electronic searches on PubMed, The Cochrane Library, EMBASE, EBSCO, Web of Science, and CINAHL databases from the inception through January 9, 2021, to identify studies evaluating the accuracy and reliability of the IJV ultrasound parameters and exploring its correlation with central venous pressure and clinical outcomes in adult patients with suspected or confirmed acutely decompensated HF. The studies' report quality was assessed by Quality Assessment of Diagnostic Accuracy Studies-2 scale.
RESULTS
A total of 11 studies were eligible for final analysis (n = 1481 patients with HF). The studies were segregated into 3 groups: (1) the evaluation of patients presenting to the emergency department with dyspnea, (2) the evaluation of patients presenting to the HF clinic for follow-up, and (3) the evaluation of hospitalized patients with acutely decompensated HF or undergoing right heart catheterization. US parameters included IJV height, IJV diameter, IJV diameter ratio, IJV cross-sectional area, respiratory compressibility index, and compression compressibility index.
CONCLUSIONS
The findings of this systematic review suggest a significant role for ultrasound interrogation of the IJV in evaluation of patients in the emergency department presenting with dyspnea, in the outpatient clinic for poor clinical outcomes in HF, and in determining the timing of discharge for patients admitted with acutely decompensated HF. Further studies are warranted for testing the reliability of the reported ultrasound indices.

Meta-Analysis
BACKGROUND
Internal jugular vein catheterization (IJVC) and subclavian vein catheterization (SCVC) have been the most preferred central venous catheterizations (CVC) clinically. Individual preference and institutional routine dominate the traditional CVC choice; however, it is lack of high-level evidence. We sought to provide better clinical strategy for CVC site choice based on anatomical landmark technique between IJVC and SCVC.
METHODS
We systematically reviewed eligible studies from PubMed, OVID, Cochrane and ClinicalTrials.Gov till February 2020. The primary outcomes were catheterization time and overall success rate, and the secondary outcomes were the first-attempt success rate and the instant mechanical complications. Ethical problems are not applicable.
RESULTS
A total of 3378 patients from 7 studies were included in the analyses. Neither difference was found on the catheterization time (SMD 95% CI: -0.095-0.124, p = 0.792), nor any difference on the overall success rate (RR = 1.017, 95% CI: 0.927-1.117, p = 0.721, I = 89.6%) between the 2 procedures. However, subgroup analyses showed overall success rate of IJVC was significantly lower than that of SCVC (RR = 0.906, 95% CI: 0.850-0.965, p = 0.002) in adults. The first-attempt success rate of IJVC group was higher in the adults (RR = 1.472, 95% CI: 1.004-2.156, p = 0.047). No significance was detected in arterial injury (RR = 1.137, 95% CI: 0.541-2.387, p = 0.735) and pneumothorax (RR = 0.600, 95% CI: 0.32-1.126, p = 0.112) between the two procedures. Hematoma was significantly more in IJVC group than that in SCVC group (RR = 2.824, 95% CI: 1.181-6.751, p = 0.02).
CONCLUSIONS
Compared with IJVC, SCVC shows a higher overall success rate while a lower first-attempt success rate in adults, and has involved with less hematoma.

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.

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.

Review
Forty years after the first totally implantable venous access device (TIVAD) implant: the pure surgical cut-down technique only avoids immediate complications that can be fatal.
AIM
Even though TIVADs have been implanted for a long time, immediate complications are still occurring. The aim of this work was to review different techniques of placing TIVAD implants to evaluate the aetiology of immediate complications.
METHODS
A systematic literature review was performed using the PubMed, Cochrane and Google Scholar databases in accordance with the PRISMA guidelines. The patient numbers, number of implanted devices, specialists involved, implant techniques, implant sites and immediate complication onsets were studied.
RESULTS
Of the 1256 manuscripts reviewed, 36 were eligible for inclusion in the study, for a total of 17,388 patients with equivalent TIVAD implantation. A total of 2745 patients (15.8%) were treated with a surgical technique and 14,643 patients (84.2%) were treated with a percutaneous technique. Of the 2745 devices (15.8%) implanted by a surgical technique, 1721 devices (62.7%) were placed in the cephalic vein (CFV). Of the 14,643 implants (84.2%) placed with a percutaneous technique, 5784 devices (39.5%) were placed in the internal jugular vein (IJV), and 5321 devices (36.3%) were placed in the subclavian vein (SCV). The number of immediate complications in patients undergoing surgical techniques was 32 (1.2%) HMMs. In patients treated with a percutaneous technique, the number of total complications were 333 (2.8%): 71 PNX (0.5%), 2 HMT (0.01%), 175 accidental artery punctures AAP (1.2%) and 85 HMM (0.6%). No mortality was reported with either technique.
CONCLUSION
The percutaneous approach is currently the most commonly used technique to implant a TIVAD, but despite specialist's best efforts, immediate complications are still occurring. Surgical cut-down, 40 years after the first implant, is still the only technique that can avoid all of the immediate complications that can be fatal.

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.
