International guidelines recommend assessing TAA characteristics via computed tomography angiography (CTA).

We included degenerative and mycotic TAAs, and exclusions were the lack of a preoperative CTA and/or incomplete postoperative imaging. A standardized measurement protocol was developed based on expert opinion and validated endovascular aortic repair (EVAR) protocols. Imaging analysis utilized dedicated 3D imaging software.

Volume measurements were similar consistent, with mean differences of 3.45 (intraobserver) and 2.75 (interobserver) cc.

The In-Vivo Optical Spectroscopy (INVOS) system, a non-invasive near-infrared spectroscopy device, measures tissue oxygenation.

To assess the effectiveness of ATH compared with BA alone in patients with femoral-popliteal artery lesions, we conducted a systematic review and meta-analysis of randomized controlled trials (RCTs).</p><p><strong>Methods: </strong>We included RCTs that focused on patients with femoral-popliteal artery lesions and reported data on the use of ATH and BA therapy.

The use of ATH in combination with BA appeared to improve the patency rate at 12 months (odds ratio [OR]=2.04, 95% confidence interval [CI]=1.14-3.62). In addition, ATH with BA was associated with lower major amputation rates (MD=2.01, 95% CI=0.06-0.77, p=0.02) and a decreased likelihood of bailout stenting (OR=0.07, 95% CI=0.02-0.25, p=0.001).

Clinicians should consider these findings when designing future RCTs and developing clinical practice guidelines.Clinical ImpactThis meta-analysis summarises a number of existing studies to advance understanding of the atherectomy devices and to reveal its potential. This new technique, when compared with drug coated balloon, shows the possibility of obtaining better clinical outcomes in femoro-popliteal lesions than drug-coated balloon alone, such as higher 12-month primary patency rates as shown in some studies. Currently, it is important to consider the appropriate technology applicable for individualised treatment. atherectomy devices seem to provide clinicians with additional options in clinical practice and to benefit patients in the future.

Asymptomatic intracranial hemorrhage was defined as any hemorrhage detected after EVT that did not fulfill the definition of symptomatic intracranial hemorrhage in the European Cooperative Acute Stroke Study.

Publication bias was not observed (Egger's p>0.1).</p><p><strong>Conclusions: </strong>This meta-analysis provides estimates for binary restenosis and primary patency following PTA utilizing prospectively collected, predominantly core-lab adjudicated data. Results demonstrate 1-year primary patency rates that are 10% to 20% higher than what has been historically used in power calculations. These new estimates will help facilitate more accurate power analysis for future RCTs.Clinical ImpactRates of primary patency and binary restenosis after percutaneous transluminal angioplasty (PTA) have not been well-described using high-quality data, and investigators have been utilizing estimates of 40% to 50% and 45% to 65%, respectively, when performing power calculations for trials. This meta-analysis demonstrates using high-quality, prospectively collected, and predominantly core-lab adjudicated randomized controlled trial data that actual rates of primary patency are closer to 60% up to 1 year following PTA and provides the first meta-analysis estimate of binary restenosis rates up to 1 year after PTA. These estimates will help facilitate more accurate power calculations for future RCTs in this space.</p>","PeriodicalId":50210,"journal":{"name":"Journal of Endovascular Therapy","volume":" ","pages":"1547-1561"},"PeriodicalIF":1.5,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138441531","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The patients with a target vessel different from the left subclavian artery (LSA) were excluded.</p><p><strong>Results: </strong>A total of 63 patients were treated for a pathological arch in zone 2 with a single-fenestrated PMEG. 73% were male, and the mean age was 65 years old. 25% were treated for a degenerative aneurysm, 19% for a post dissection aneurysm and 24% for an acute type B dissection. 52% of the patients were treated as an emergency and half of those for an aortic rupture. The LSA fenestration was stented in 70%. During 30 days of follow-up, 2 strokes (3%) were reported, 6 patients (10%) died with 4 of those treated for aortic rupture and 1 had a retrograde aortic dissection. During at least 3 years of follow-up (median 49 months), no reintervention was needed for endoleaks, there was no stent fracture or stent migration. No patient died from an aortic cause. Subgroup analysis comparing the endovascular treatment for various aortic pathologies did not find significant differences in death rate or comorbidity including stroke. When comparing emergent and elective aortic repair, operating time was similar (64 vs 65 minutes), and the LSA fenestration was less frequently stented (52%) in the emergency group. There was no difference in stroke frequency. There was a higher rate of death in the emergency group at 30 days of follow-up, but no patient died from aortic cause in the long-term follow-up.</p><p><strong>Conclusions: </strong>Aortic arch repair with single-fenestrated PMEGs for zone 2 pathological arch disease is associated with acceptable early and midterm major morbidity and mortality. It is suitable for emergency situations.Clinical ImpactSingle-fenestrated PMEG for the left subclavian artery is a safe and efficient option in the short and medium term for the treatment of the aortic arch in zone 2 with 98% technical success. It allows for aortic repair and subclavian artery revascularization in a single step for all patients. It is suitable for a range of main pathologies, including degenerative, dissection-related, isthmus rupture, and embolic pathologies. Additionally, it is always available and easily utilized in emergency cases.</p>","PeriodicalId":50210,"journal":{"name":"Journal of Endovascular Therapy","volume":" ","pages":"1614-1622"},"PeriodicalIF":1.5,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138483326","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
