Review
OBJECTIVE
Preoperative embolization has proven beneficial in the surgical treatment of juvenile nasopharyngeal angiofibromas (JNA). However, the consensus for the best embolization practices remains unclear. This systematic review seeks to characterize the reporting of embolization protocols throughout the literature and to compare differences in surgical outcomes.
DATA SOURCES
PubMed, Embase, and Scopus.
REVIEW METHODS
Studies investigating embolization in the treatment of JNA from 2002 to 2021 were selected from defined inclusion criteria. All studies underwent a 2-stage blinded screening, extraction, and appraisal process. Embolization material, time to surgery, and embolization route were compared. Embolization complications, surgical complications, and rate of recurrence were pooled.
RESULTS
Of 854 studies, 14 retrospective studies with 415 patients met the criteria for inclusion. A total of 354 patients underwent preoperative embolization. A total of 330 patients (93.2%) underwent transarterial embolization (TAE) and 24 patients had a combination of direct puncture embolization and TAE. Polyvinyl alcohol particles were the most used embolization material (n = 264, 80.0%). The most common reported time to surgery was 24 to 48 hours (n = 8, 57.1%). Pooled results showed an embolization complication proportion of 3.16% (95% confidence interval [CI]: 0.96-6.60) (n = 354), a surgical complication proportion of 4.96% (95% CI: 1.90-9.37) (n = 415), and a recurrence proportion of 6.30% (95% CI: 3.01-10.69) (n = 415).
CONCLUSION
The current data on JNA embolization parameters and their effect on surgical outcomes remains too heterogenous to provide expert recommendations. Future studies should use uniform reporting to allow for more robust comparisons of embolization parameters, which, in turn, may lead to optimized patient outcomes.

Meta-Analysis
A systematic review and meta-analysis comparing intrawound vancomycin powder and povidone iodine lavage in the prevention of periprosthetic joint infection of hip and knee arthroplasties.
BACKGROUND
Focus on reviewing a vigorous research effort to improve the safety profile of vancomycin powder (VP) and its optimal dose in reducing periprosthetic joint infection (PJI) is the need of the hour. This systematic review and meta-analysis attempt to explore the ongoing use of VP and VP + povidone iodine (PI) lavage to prevent PJI of hip/knee arthroplasties and highlights its challenges among the orthopedic community about the existence of the major organism and its frequency in total joint arthroplasty (TJA) patients.
METHODS
We searched PubMed/MEDLINE, EMBASE databases regarding the outcomes of vancomycin powder (VP) and VP + povidone iodine (PI) combination in preventing periprosthetic joint infection of hip and knee arthroplasties.
RESULTS
In 5 of 7 studies, the combination of vancomycin powder (VP) and povidone iodine (PI) lavage have shown a lower risk of periprosthetic joint infection (PJI) in acute and high-risk hip and knee arthroplasties patients, with less or without serious adverse events and readmissions; while four of seven studies using VP-only found increasing rates of PJI in primary total knee arthroplasty and partial hip replacement in elderly patients with comorbidities, and significantly causes aseptic wound complications compared to the control group.
CONCLUSIONS
Intra-articular vancomycin powder (VP) and povidone iodine (PI) lavage showed a significant reduction of periprosthetic joint infection in primary and revision total joint arthroplasty. Before its widespread use in clinical settings, prospective randomized studies and, most importantly, its long-term efficacy and safety are recommended.

Meta-Analysis
BACKGROUND
There is little evidence in scientific literature assessing the safety and efficacy of dual-lumen balloon catheters (DLBCs) and their performance compared to single-lumen catheters (SLCs).
METHODS
In this PROSPERO-registered, PRISMA-compliant systematic review, we identified all MEDLINE and EMBASE single-arm (DLBCs) and double-arm (DLBCs vs SLCs) cohorts where DLBCs were used for the treatment of cerebral arteriovenous malformations (AVMs) or dural arteriovenous fistulas (dAVFs). Immediate angiographic outcome, vascular complications, technical failures, reflux episodes and entrapment were the primary outcomes. A meta-analysis of the double-arm studies summarized the primary outcomes of total procedural time and immediate angiographic outcome.
RESULTS
The authors identified 18 studies encompassing 209 treated lesions with reported outcomes. Complete occlusion was achieved in 108/132 treated dAVFs (81.8%, 95% CI: [74-87.8%]) and in 45/77 treated AVMs (58.4%, [46.7-69.4%]). The proportion of completely occluded dAVFs was statistically significantly higher than that of AVMs, < .001. There were eight reported vascular complications (3.8%, [1.8-7.7%]), five technical failures (2.4%, [0.9-5.8%]), 14 reflux events (6.7%, [3.9-11.2%]), two entrapment events (1%, [0.2-3.8%]) and 0 deaths (mortality rate 0%, [0-2.3%]). In a meta-analysis for the treatment of dAVFs, the total procedural time was significantly less for DLBCs compared to SLCs (64.9 vs 125.7 min, < .0001). The odds of complete immediate occlusion were significantly higher with DLBCs compared to SLCs (odds ratio (OR) 4.6, [1.5-14.3], = .008).
CONCLUSION
Dual-lumen balloon catheters are safe and effective for the embolization of cerebral AVMs and dAVFs and can achieve faster and potentially superior results compared to SLCs.
