Patients' recruitment lasted from 2013 to 2017, and postoperative follow-up was up to 5 years. A computed tomography angiography (CTA) was performed at the first month and then at 1, 2, and 5 years.

Both the suprarenal aorta and the PAN significantly dilated overtime, with PAN dilating more progressively. Mean neck dilatation at the juxtarenal level was 0.8±0.4 mm at 1 year, 1.8±0.8 mm at 2 years, and 3.9±1.7 mm at 5 years, with a mean neck dilatation rate of 0.07 mm/month overall. The incidence of AND ≥2.5 mm was 37.2% at 2 years and 58.1% at 5 years after EVAR and was considered important (≥5 mm) in 11.5% of patients at 2 years and 30.6% of patients at 5 years. A multivariate analysis performed showed that the endograft oversizing, the preoperative neck diameter, and the preoperative abdominal aortic aneurysm sac diameter served as independent predictors of AND at 5 years. At the 5-year follow-up, 8 late type Ia endoleaks (6.5%) and 7 caudal migrations (5.6%) were identified, while no late ruptures were reported.

Satisfactory early and long-term results in the TBAD and thoracic arch aneurysm (TAA) groups were obtained with zones 1 and 2 landing TEVAR. The TBAD cases had the same good results as the TAA cases. Using our strategy, we especially might reduce complications and be an effective treatment for acute complicated TBAD.</p>","PeriodicalId":50210,"journal":{"name":"Journal of Endovascular Therapy","volume":" ","pages":"170-184"},"PeriodicalIF":1.7,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9512774","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}

Short-term data were promising, but long-term data are still lacking. The objective was to report the long-term outcomes of CERAB for extensive aorto-iliac occlusive disease and to identify predictors for loss of primary patency.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;Consecutive electively treated patients with CERAB for aorto-iliac occlusive disease in a single hospital were identified and analyzed. Baseline and procedural data and follow-up were collected at 6-weeks, 6 months, 12 months, and annually thereafter. Technical success, procedural, and 30-day complications were evaluated, as well as overall survival. Patency and freedom from target lesion revascularization rates were analyzed using Kaplan Meier curves. Uni- and multivariate analysis were performed to identify possible predictors of failure.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;One hundred and sixty patients were included (79 male). Indication for treatment was intermittent claudication for 121 patients (75.6%) and 133 patients (83.1%) had a TASC-II D lesion. Technical success was obtained in 95.6% of patients and the 30-day mortality rate was 1.3%. The 5-year primary, primary-assisted, and secondary patency rates were 77.5%, 88.1%, and 95.0%, respectively, with a freedom-from clinically driven target lesion revascularization (CD-TLR) rate of 84.4%. The strongest predictor of loss of primary patency of CERAB was a previous aorto-iliac intervention (odds ratio [OR]=5.36 (95% confidence interval [CI]: 1.30; 22.07), p=0.020). In patients not previously treated in the aorto-iliac tract, 5-year primary, primary assisted, and secondary patency rates were 85.1%, 94.4%, and 96.9%, respectively. At 5-year follow-up, an improved Rutherford was found in 97.9% of patients and the freedom from major amputation rate was 100%.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusion: &lt;/strong&gt;The CERAB technique is related to good long-term outcomes, particularly in primary cases. In patients that had prior treatment for aorto-iliac occlusive disease, there were more reinterventions and therefore surveillance should likely be more intense.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Clinical impact: &lt;/strong&gt;The Covered Endovascular Reconstruction of the Aortic Bifurcation (CERAB) reconstruction was designed to improve outcomes of endovascular treatment of extensive aorto-iliac occlusive disease. At 5-year follow-up clinical improvement was found in 97.9% of patients without major amputations. The 5-year overall primary, primary-assisted, and secondary patency rates were 77.5%, 88.1%, and 95.0%, respectively, with a freedom-from clinically driven target lesion revascularization rate of 84.4%. Significantly better patency rates were observed for patients that were never treated before in the target area.
