The primary endpoint of the study was clinical success rate, while the secondary endpoints were 6- or 12-month vascular patency rates.ResultsOf the 24 treatment instances enrolled, 20 were primary onset and treated initially with percutaneous transluminal angioplasty under color duplex ultrasound guidance. Of these 20 patients, 17 were treated successfully (85%), while 3 procedures failed, requiring reoperation. Six patients showed recurrence within 1 year, of which four received repeated ultrasound-guided percutaneous transluminal angioplasty. Three of these procedures were successful (75.0%). Therefore, the total success rate was 83.3%. The patency rates were 76.5% at the 6-month follow-up and 64.7% at the 12-month follow-up.

Among these patients, 22 were treated using ligamentum flavum suspension surgery while preserving the ligamentum flavum, combined with the annulus fibrosus suture technique. We analyzed the demographic information, preoperative and postoperative imaging data, and clinical outcomes of these 22 patients.ResultsThese 22 patients were followed for 6-15 months; at the last follow-up, the improvement in postoperative functional evaluations, such as the Oswestry Disability Index, was statistically significant (P < 0.05).

There were no instances of postoperative recurrence, although one patient exhibited postoperative dysesthesia.ConclusionUni-portal non-coaxial spinal endoscopic surgery is straightforward, versatile, and flexible. Preservation of the ligamentum flavum significantly helps prevent epidural fibrosis.

{"title":"Evaluation of the diagnostic performance of ultrasound for clavicle fractures in emergency settings: A meta-analysis and systematic review.","authors":"Bin Lin, Danqin Yuan, Weiting Chen, Ying Liu, Xiaozhen Ji","doi":"10.1177/03000605251351273","DOIUrl":"10.1177/03000605251351273","url":null,"abstract":"<p><p>ObjectiveUltrasound provides real-time, high-resolution imaging and is increasingly recognized as a valuable diagnostic tool for clavicle fractures. Compared with traditional imaging modalities, ultrasound offers advantages such as point-of-care accessibility, absence of radiation exposure, and rapid diagnosis capability, making it particularly useful in emergency settings. However, the diagnostic performance of ultrasound across different clinical studies remains inconsistent. Therefore, this study aimed to systematically assess the diagnostic accuracy of ultrasound for clavicle fractures through a meta-analysis of existing studies.MethodsA systematic review and meta-analysis was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. A comprehensive search of PubMed, Scopus, Embase, Cochrane Library, and Web of Science was performed until 25 February 2025. Studies reporting the sensitivity, specificity, and overall diagnostic performance of ultrasound for clavicle fractures were included. Data extraction and statistical analysis were performed using Stata version 18.0.ResultsA meta-analysis of seven eligible studies showed a pooled sensitivity of 92% (95% confidence interval: 87%-95%) and pooled specificity of 95% (95% confidence interval: 91%-98%), indicating relatively high diagnostic accuracy. Sensitivity showed low-to-moderate heterogeneity, whereas specificity demonstrated significant heterogeneity. Fagan plot and likelihood ratio analysis supported the clinical utility of ultrasound for both confirming and excluding clavicle fractures. The likelihood ratio scattergram indicated that ultrasound shows good performance in ruling in clavicle fractures but only moderately good performance in ruling them out.ConclusionCurrent evidence indicates that ultrasound is a promising, noninvasive diagnostic modality for clavicle fractures, especially in emergency settings. Its diagnostic accuracy, coupled with its safety profile, makes it a potentially valuable tool. Nevertheless, standardization of scanning protocols and further validation in diverse populations are needed. Future studies are warranted to standardize scanning protocols, evaluate operator-dependent factors, and validate findings across broader clinical settings.<b>Trial registration number:</b> PROSPERO CRD: 42025643069.</p>","PeriodicalId":16129,"journal":{"name":"Journal of International Medical Research","volume":"53 6","pages":"3000605251351273"},"PeriodicalIF":1.4,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12198571/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144497331","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are various treatment methods for retinal artery occlusion, but their effect remains unclear. Cilioretinal artery occlusion post-intravitreal drug injection is rare, with no relevant reports published to date. A man in his early 50s was admitted to our department due to a nail injury to the right eye. The patient underwent exploratory and suture surgery for eyeball penetrating injury, intraocular foreign body removal, and intravitreal vancomycin injection. The patient's preoperative visual acuity in the right eye was 0.1, which decreased to FC/5 cm one day after surgery. Wide-angle fundus photography revealed cilioretinal artery occlusion. We highly suspected that the sudden increase in intraocular pressure after intravitreal injection of vancomycin was the cause of cilioretinal artery occlusion in this case. Mouse nerve growth factor (30 μg) and anisodine hydrobromide tablets (3 mg) were used for neurotrophic and microcirculation-improving treatments. Follow-up fundus fluorescein angiography at 31 seconds on postoperative day 18 showed filling of the cilioretinal artery. At 14 months post-surgery, the patient's right eye visual acuity recovered to 0.1.
