Background. The complex endovascular repair of aortic aneurysms and dissections with fenestrated or branched stent grafts (FBEVAR) 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 withmulticenter 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 thoracic-abdominal 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
