N2 - Background: The complex endovascular repair of aortic aneurysms and dissections with fenestrated or branched stent grafts (FB-EVAR) remains challenging for interventional vascular surgery. To date, the evidence regarding treatment patterns and outcome measures consists of single center studies; however, it might be reasonable to validate results with multicenter real-world evidence.Methods: Health insurance claims data from Germany's third largest insurance provider, DAK-Gesundheit, were used to determine outcomes following FB-EVAR of non-ruptured thoracic aorta (TA) or thoracoabdominal including pararenal abdominal (TAA) aorta. The study included patients operated between January 2008 and April 2017.Results: Included were 984 patients (18.1% female) who underwent FB-EVAR. Patients with treatment of the TA were younger (71.7 vs. 73.2 years, p < 0.001) and more often female (38.5% vs. 17.0%, p < 0.001) as compared to patients with treatment of TAA. In the TA group peripheral arterial disease was less frequent compared to the TAA group (67.3% vs. 80.4%, p = 0.036). Mortality was significantly (p < 0.001) higher following repair of the TAA compared to the TA at discharge (17.3% vs. 4.6%), at 30 days (26.9% vs. 8.2%) and at 90 days (34.6% vs. 10.1%). Patients with treatment of the TAA suffered more often from stroke as compared to the TA group (7.7% vs. 1.2%, p = 0.002).Conclusion: In this large-scale German analysis of claims data, multicenter real-world evidence was different from single center studies regarding patient risk-factors and outcome measures. Validated multicenter registry studies could help to further investigate this topic in times of increasing procedures.
