Meta-Analysis Review
INTRODUCTION
A brachiobasilic arteriovenous fistula (BB-AVF) can provide access for haemodialysis in patients who are not eligible for a more superficial fistula. However, it is unclear whether one- or two-stage BB-AVF is the best option for patients.
AIM
To systematically assess the difference between both procedures in terms of access maturation, patency and postoperative complications.
METHODS
Online search for randomised controlled trials (RCTs) and observational studies that compared the one-stage versus the two-stage technique for creating a BB-AVF.
RESULTS
Eight studies were included (849 patients with 859 fistulas), 366 created using a one-stage technique, while 493 in a two-stage approach. There was no statistically significant difference between the two groups in the rate of successful maturation (Pooled risk ratio = 0.95 [0.82, 1.11], P = 0.53). Similarly, the incidence of postoperative haematoma (Pooled risk ratio = 0.73 [0.34, 1.58], P = 0.43), wound infection (Pooled risk ratio = 0.77 [0.35, 1.68], P = 0.51) and steal syndrome (Pooled risk ratio = 0.65 [0.27, 1.53], P = 0.32) were statistically comparable.
CONCLUSION
Although more studies seem to favour the two-stage BVT approach, evidence in the literature is not sufficient to draw a final conclusion as the difference between the one-stage and the two-stage approaches for creation of a BB-AVF is not statistically significant in terms of the overall maturation rate and postoperative complications. Patency rates (primary, assisted primary and secondary) were comparable in the majority of studies. Large randomised properly conducted trials with superior methodology and adequate sub-group analysis are needed before making a final recommendation.

Comparative efficacy and safety of four common balloon angioplasty techniques for an arteriovenous fistula or graft stenosis: a systematic review and network meta-analysis of randomized controlled trials.
BACKGROUND
Balloon angioplasty could decrease restenosis of hemodialysis vascular access. The present study investigated the comparative effects and safety of commonly available balloon angioplasty techniques for treating patients with failing autogenous arteriovenous fistulas (AVFs) and grafts (AVGs) stenosis.
METHODS
A comprehensive literature search, including an updated search of PubMed and Embase (via Ovid) and screening of published meta-analyses, was conducted. Primary patency at 6 and 12 months was the primary outcome, and the incidence of complications was the secondary outcome. The random-effects model was used to conduct all statistical analyses, which were performed using RevMan 5.3 and ADDIS 1.16.8.
RESULTS
A total of 20 eligible studies involving four balloon angioplasty techniques were entered into the final analysis. Although the direct meta-analysis indicated that cutting balloon angioplasty (CtBA) significantly improved primary patency at 6 [odds ratio (OR), 1.91; 95% confidence interval (CI): 1.27 to 2.86] and 12 (OR, 1.56; 95% CI: 1.13 to 2.15) months compared with conventional balloon angioplasty (CBA), this was not supported by network meta-analysis, which suggested that CtBA was associated with a higher risk of complications compared with drug-coated balloon angioplasty (DcBA) [OR, 0.05; 95% credible interval (CrI): 0.00 to 0.83], high-pressure balloon angioplasty (HBA) (OR, 0.04; 95% CrI: 0.00 to 0.69), and CBA (OR, 0.11; 95% CrI: 0.02 to 0.59). Subgroup analysis of AVFs did not detect any significant differences.
CONCLUSIONS
In failing AVF and AVG stenosis, HBA might be a preferential option as it is related to a lower risk of complications and has numerically higher primary patency than DcBA and CBA. Further studies are needed to confirm these findings.

Review
BACKGROUND/PURPOSE
The purpose of this systematic review is to update the available data for complications following orthognathic surgery in cleft lip and/or palate patients.
METHODS
Three electronic databases (Medline, Embase, and Cochrane) were searched for publications from 1990 to 2014.
RESULTS
A total of 26 articles were selected including 1003 patients (male: 391, female: 353, 259: not mentioned) who underwent maxillary osteotomies for cleft lip/palate. Mean age at surgery was 19.3 years (range: 8.5-60 years). Overall perioperative complications were reported in 126 cases (12.76%). The most common complication was closure failure of pre-existing palatal fistula (28.57%), followed by velopharyngeal impairment (16.79%), closure failure of pre-existing alveolar fistula (10.74%), gingival recession (4.55%), and failure of premaxilla stabilization in bilateral cases (4.55%). Severe vascular complications included one arteriovenous fistula (0.10%), one maxillary aneurysm (0.10%), and one cavernous sinus thrombosis (0.10%). Mean horizontal relapse rate was 17.9% (range: -20.0% to 37.2%), and mean vertical relapse rate was 35.4% (range: -25.9% to 162.5%). Reoperation rate was 12.2% (range: 0.0-64.0%). Prospective studies or randomized trials were rare.
CONCLUSION
To obtain a dataset with higher evidence, a prospective multicenter study should be conducted with clearly defined criteria for each complication.

Dialysis Access-Associated Steal Syndrome in High-Risk Patients Undergoing Surgery for Hemodialysis Access: A Systematic Review and Meta-Analysis of Preventive Operative Techniques.
This systematic review and meta-analysis examine preventive operative techniques in high-risk patients undergoing surgery for hemodialysis access to mitigate the risk of Dialysis Access-Associated Steal Syndrome (DASS). Chronic kidney disease often leads to end-stage renal disease (ESRD), necessitating dialysis. Successful vascular access is crucial for efficient dialysis, but complications, such as DASS, pose significant challenges. DASS redirects arterial blood flow, affecting populations undergoing arteriovenous access surgery. This study aims to assess preventive strategies, including distal revascularization with interval ligation (DRIL) and extension techniques. A systematic search of PubMed, Cochrane Library, EMBASE, and Web of Science until 2022 identified 11 relevant studies. The inclusion criteria comprised non-pediatric hemodialysis patients reporting outcomes related to patency and complications. The data were analyzed using Review Manager 5.3.5 (The Nordic Cochrane Centre, The Cochrane Collaboration, Copenhagen). Meta-analysis indicated a significant association between DASS and arteriovenous fistula (AVF) or arteriovenous graft (AVG) procedures. Radiocephalic AVF (RC-AVF) and distal endovascular AVF procedures were favored. Various interventions addressed venous narrowing, including simple plication and loop interposition. The Modified by Inserted Latex Link for Endovascular Repair (MILLER) technique, DRIL, Extension Technique, and Proximalization of Arterial Inflow (PAI) were assessed for arterial bypass graft and blood supply preservation. This study underscores the importance of individualized strategies in preventing DASS during hemodialysis access surgery. Prophylactic measures, such as the extension technique, show promise, while DRIL remains effective in treatment. Ongoing research is imperative for optimizing outcomes in this complex patient population.

BACKGROUND
Proximal femoral fracture (PFF), such as intertrochanteric femoral fracture or femur neck fracture, and its management are crucial issues to surgeons. PFF has been dramatically is becoming exponentially prevalent, and it is at high risk of complication and mortality because it is frequently associated with serious trauma and advanced age, especially in patients treated with anticoagulants or antiplatelet agents. Surgical management is essential for the treatment of PFF. Unfortunately, current surgical procedures have been related to accompanied by vascular complications, including laceration, hemorrhage, thrombosis, embolism, intimal flap tear and pseudoaneurysm. Furthermore, these vascular injuries following surgical management of PFF are potentially limb- and life-threatening. Of the complications after operation of PFF, femoral arteriovenous fistula (AVF) is rare, but remains a challenging problem because it is frequently associated with significantly high mortality and morbidity and is very difficult to treat.
METHODS
A systematic literature review was conducted using the PRISMA guidelines with no language restriction. We searched scientific publications via PubMed, Embase, Cochrane central register of controlled trial, Google Scholar, the KoreaMed and the Research Information Sharing Service database. The goal of this study was to report on the incidence, clinical presentation, diagnosis, treatment, associated complications, morbidity and mortality of femoral AVF caused by PFF and to draw special attention to its prevention and management.
RESULTS
A total of 7 case reports on femoral AVF associated with operation of PFF were identified, and one our case was added to the systematic analysis. Of the 8 cases, 4 were male and 4 were female under the age of 67.87±18.44; 6 (75.0%) survived without any events, 1 (12.5%) survived with a sequela of peroneal nerve impairment, and 1 (12.5%) died of multi-organ failure and hypovolemia.
CONCLUSIONS
The incidence of femoral AVF associated with PFF is extremely low, though it appears to increase with the rising frequency of PFF. With a very few exceptions, complications following internal fixation are potentially limb- and life-threatening. There is still no definite consensus on the standardized diagnostic or therapeutic modalities. Therefore, surgeons should keep in mind that this serious complication requires early diagnosis and prompt treatment, which should not be underestimated. Femoral AVF following operation of PFF should be meticulously managed, because untreated fistulae result in serious unexpected complications including renin-mediated hypertension, high-output heart failure and venous and/or arterial insufficiency. Surgical treatment is still the gold standard for such cases, but in limited cases endovascular procedures using embolization and closure device can be a good treatment option.

BACKGROUND
Despite the recent increase in the number of publications on diagnostic cerebral angiograms using transradial access (TRA), there have been relatively few regarding TRA for neurointerventional cases. Questions of feasibility and safety may still exist among physicians considering TRA for neurointerventional procedures.
METHODS
A systematic literature review was performed following PRISMA guidelines. Three online databases (MedLine via PubMed, Scopus and Embase) were searched for articles published between January 2000 and December 2019. Search terms included "Transradial access", "Radial Access", "Radial artery" AND "Neurointerventions". The reference lists of selected articles and pertinent available non-systematic analysis were reviewed for other potential citations. Primary outcomes measured were access site complications and crossover rates.
RESULTS
Twenty-one studies (n=1342 patients) were included in this review. Two of the studies were prospective while the remaining 19 were retrospective. Six studies (n=616 patients) included TRA carotid stenting only. The rest of the studies included treatment for cerebral aneurysms (n=423), mechanical thrombectomy (n=127), tumor embolization (n=22), and other indications (n=154) such as angioplasty and stenting for vertebrobasilar stenosis, balloon test occlusion, embolization of dural arteriovenous fistula and arteriovenous malformation, chemotherapeutic drug delivery, intra-arterial thrombolysis, and arterial access during a venous stenting procedure. Two (0.15%) major complications and 37 (2.75%) minor complications were reported. Sixty-four (4.77%) patients crossed over to transfemoral access for completion of the procedure. Seven (0.52%) patients crossed over due to access failure and 57 (4.24%) patients crossed over to TFA due to inability to cannulate the target vessel.
CONCLUSION
This systematic review demonstrates that TRA has a relatively low rate of access site complications and crossovers. With increasing familiarity, development of TRA-specific neuroendovascular devices, and the continued reports of its success in the literature, TRA is expected to become more widely used by neurointerventionalists.

Meta-Analysis Review
OBJECTIVE/BACKGROUND
Existing guidelines suggest routine use of pre-operative color Doppler ultrasound (DUS) vessel mapping before the creation of arteriovenous fistulae (AVF); however, there is controversy about its benefit over traditional clinical examination or selective ultrasound use.
METHODS
This was a systematic review and meta-analysis of randomized controlled trials (RCTs) comparing routine DUS mapping before the creation of AVF with patients for whom the decision for AVF placement was based on clinical examination and selective ultrasound use. A search of MEDLINE/PubMed, SCOPUS, and the Cochrane Library was carried out in June 2014. The analyzed outcome measures were the immediate failure rate and the early/midterm adequacy of the fistula for hemodialysis. Additionally, assessment of the methodological quality of the included studies was carried out.
RESULTS
Five studies (574 patients) were analyzed. A random effects model was used to pool the data. The pooled odds ratio (OR) for the immediate failure rate was 0.32 (95% confidence interval [CI] 0.17-0.60; p < .01), which was significantly in favor of the DUS mapping group. The pooled OR for the early/midterm adequacy for hemodialysis was 0.66 (95% CI 0.42-1.03; p = .06), with a trend in favor of the DUS mapping group; however, subgroup analysis revealed that routine DUS mapping was more beneficial than selective DUS (p < .05).
CONCLUSION
The available evidence, based mainly on moderate quality RCTs, suggests that the pre-operative clinical examination should always be supplemented with routine DUS mapping before AVF creation. This policy avoids negative surgical explorations and significantly reduces the immediate AVF failure rate.

Comparative Study Meta-Analysis
Paclitaxel coated balloon versus conventional balloon angioplasty in dysfunctional dialysis arteriovenous fistula: a systematic review and meta-analysis of randomized controlled trials.
PURPOSE
To compare the efficacy and safety between paclitaxel coated balloon (PCB) angioplasty and conventional balloon (CB) angioplasty in the treatment of dysfunctional arteriovenous fistula (AVF).
METHODS
We searched four major electronic databases (PubMed, EMBASE, Web of Science and the Cochrane Library) for randomized controlled trials (RCTs) published from inception through November 28, 2021. Outcomes of interest included target lesion primary patency (TLPP), technical success and all-cause mortality. The STATA package version 15.1 was utilized to undertake meta-analyses.
RESULTS
Fourteen RCTs totaling 1535 patients were analyzed. The available data showed that there were no significant differences of TLPP rates at 3, 6, 9 and 12 months between the PCB group and the CB group (risk ratio (RR) 1.00, 95% confidence interval (CI) 0.93-1.07, = 1.000, = 33.5%, Cochrane test = 0.185, fixed-effect model; RR 1.17, 95% CI 0.99-1.39, = 0.065, = 75.4%, Cochrane test = 0.000, random-effect model; RR 0.81, 95% CI 0.35-1.89, = 0.625, = 62.8%, Cochrane test = 0.045, random-effect model; RR 1.19, 95% CI 0.97-1.47, = 0.096, = 40.5%, Cochrane test = 0.071, random-effect model). In addition, two groups had similar technical success rates (RR 1.00, 95% CI 0.97-1.03, = 1.000, = 0.0%, Cochrane test = 0.596, fixed-effect model) and all-cause mortality rates (RR 1.00, 95% CI 0.54-1.84, = 1.000, = 0.0%, Cochrane test = 0.599, fixed-effect model).
CONCLUSIONS
PCB angioplasty did not appear to convey any obvious advantage over CB angioplasty in the treatment of dysfunctional AVF. However, further multi-center, large-scale and well-designed RCTs are needed to prove outcomes.

Meta-Analysis Review
BACKGROUND
Guidelines recommend routine arteriovenous (AV) graft and fistula surveillance (technology-based screening) in addition to clinical monitoring (physical examination) for early identification and pre-emptive correction of a stenosis before the access becomes dysfunctional. However, consequences on patient-relevant outcomes of pre-emptive correction of a stenosis in a functioning access as opposed to deferred correction, i.e. correction postponed to when the access becomes dysfunctional, are uncertain.
OBJECTIVES
We aimed to evaluate 1) whether pre-emptive correction of an AV access stenosis improves clinically relevant outcomes; 2) whether the effects of pre-emptive correction of an AV access stenosis differ by access type (fistula versus graft), aim (primary and secondary prophylaxis), and surveillance method for primary prophylaxis (Doppler ultrasound for the screening of functional and anatomical changes versus measurement of the flow in the access); and 3) whether other factors (dialysis duration, access location, configuration or materials, algorithm for referral for intervention, intervention strategies (surgical versus radiological or other), or study design) explain the heterogeneity that might exist in the effect estimates.
SEARCH METHODS
We searched the Cochrane Kidney and Transplant Specialised Register to 30 November 2015 using search terms relevant to this review.
SELECTION CRITERIA
We included all studies of any access surveillance method for early identification and pre-emptive treatment of an AV access stenosis.
DATA COLLECTION AND ANALYSIS
We extracted data on potentially remediable and irremediable failure of the access (i.e. thrombosis and access loss respectively); infection and mortality; and resource use (hospitalisation, diagnostic and intervention procedures). Analysis was by a random effects model and results expressed as risk ratio (RR), hazard ratio (HR) or incidence rate ratio (IRR) with 95% confidence intervals (CI).
MAIN RESULTS
We identified 14 studies (1390 participants), nine enrolled adults without a known access stenosis (primary prophylaxis; three studies including people using fistulas) and five enrolled adults with a documented stenosis in a non-dysfunctional access (secondary prophylaxis; three studies in people using fistulas). Study follow-up ranged from 6 to 38 months, and study size ranged from 58 to 189 participants. In low- to moderate-quality evidence (based on GRADE criteria) in adults treated with haemodialysis, relative to no surveillance and deferred correction, surveillance with pre-emptive correction of an AV stenosis reduced the risk of thrombosis (RR 0.79, 95% CI 0.65 to 0.97; I² = 30%; 18 study comparisons, 1212 participants), but had imprecise effect on the risk of access loss (RR 0.81, 95% CI 0.65 to 1.02; I² = 0%; 11 study comparisons, 972 participants). In analyses subgrouped by access type, pre-emptive stenosis correction did not reduce the risk of thrombosis (RR 0.95, 95% CI 0.8 to 1.12; I² = 0%; 11 study comparisons, 697 participants) or access loss in grafts (RR 0.9, 95% CI 0.71 to 1.15; I² = 0%; 7 study comparisons; 662 participants), but did reduce the risk of thrombosis (RR 0.5, 95% CI 0.35 to 0.71; I² = 0%; 7 study comparisons, 515 participants) and the risk of access loss in fistulas (RR 0.5, 95% CI 0.29 to 0.86; I² = 0%; 4 studies; 310 participants). Three of the four studies reporting access loss data in fistulas (199 participants) were conducted in the same centre. Insufficient data were available to assess whether benefits vary by prophylaxis aim in fistulas (i.e. primary and secondary prophylaxis). Although the magnitude of the effects of pre-emptive stenosis correction was considerable for patient-centred outcomes, results were either heterogeneous or imprecise. While pre-emptive stenosis correction may reduce the rates of hospitalisation (IRR 0.54, 95% CI 0.31 to 0.93; I² = 67%; 4 study comparisons, 219 participants) and use of catheters (IRR 0.58, 95% CI 0.35 to 0.98; I² = 53%; 6 study comparisons, 394 participants), it may also increase the rates of diagnostic procedures (IRR 1.78, 95% CI 1.18 to 2.67; I² = 62%; 7 study comparisons, 539 participants), infection (IRR 1.74, 95% CI 0.78 to 3.91; I² = 0%; 3 studies, 248 participants) and mortality (RR 1.38, 95% CI 0.91 to 2.11; I² = 0%; 5 studies, 386 participants).In general, risk of bias was high or unclear in most studies for many domains we assessed. Four studies were published after 2005 and only one had evidence of registration within a trial registry. No study reported information on authorship and/or involvement of the study sponsor in data collection, analysis, and interpretation.
AUTHORS' CONCLUSIONS
Pre-emptive correction of a newly identified or known stenosis in a functional AV access does not improve access longevity. Although pre-emptive stenosis correction may be promising in fistulas existing evidence is insufficient to guide clinical practice and health policy. While pre-emptive stenosis correction may reduce the risk of hospitalisation, this benefit is uncertain whereas there may be a substantial increase (i.e. 80%) in the use of access-related procedures and procedure-related adverse events (e.g. infection, mortality). The net effects of pre-emptive correction on harms and resource use are thus unclear.

Primary Balloon Angioplasty Versus Hydrostatic Dilation for Arteriovenous Fistula Creation in Patients with Small-Caliber Cephalic Veins: A Systematic Review and Meta-Analysis.
BACKGROUND
For arteriovenous fistula (AVF) presence of a venous segment with adequate diameter is essential which is lacking in many patients. To find the optimal augmentation technique in patients with small-caliber cephalic vein (i.e., cephalic vein diameter <3 mm), studies compared primary balloon angioplasty (PBA) versus hydrostatic dilation (HD); however, it remained debatable. This systematic review seeks to determine which technique is preferable.
METHODS
We searched MEDLINE, PubMed, Embase, and Google Scholar. Primary outcomes were 6-month primary patency, reintervention, and working AVF. Secondary outcomes were immediate success, the AVF's maturation time (day), and surgical site infection.
RESULTS
Three randomized controlled trials yielding 180 patients were included, of which 89 patients were in the PBA group. The odds ratio (OR) of primary patency was significantly higher in the PBA group (OR 6.09, 95% confidence interval [CI], 2.36-15.76, P = 0.0002), the OR of reintervention was significantly lower in the PBA group (OR 0.16, 95% CI, 0.06-0.42, P = 0.0002), and the OR of working AVF was greater in PBA group (OR 4.22, 95% CI, 1.31-13.59, P = 0.02). The OR of immediate success was significantly greater in the PBA group (OR 11.42, 95% CI, 2.54-51.42, P = 0.002), and the AVF maturation time was significantly shorter in patients who underwent PBA (mean difference -20.32 days, 95% CI, -30.12 to -10.52, P = 0.0001). The certainty of the evidence was high.
CONCLUSIONS
PBA of small cephalic veins with diameter ≤2.5 cm is a safe, feasible, and efficacious augmentation method for AVF creation. This technique achieves favorable maturation outcomes, and PBA is superior to the standard hydrostatic dilatation technique.
