DeGIR Quality Report 2019: Report on the treatment quality of minimally invasive methods - Interventional therapy (EVAR) of abdominal aortic aneurysms

Purpose To analyze the quality of endovascular aortic aneurysm repair using the data of the DeGIR quality management system. Comparison of data between 2011 and 2019. Materials and Methods A retrospective analysis of all data registered in the DeGIR quality management system of the year 2019 was performed regarding the treatment quality for endovascular aortic aneurysm repair. Registration of data was voluntary. As quality parameters indication, treatment process data and quality of results were examined. The latter was judged by treatment success, complication rates and radiation exposure. Results Out of 189590 data sets overall 1639 cases of EVAR were registered; compared to 2011 this was an increase of 472 cases. 5.9% of these cases encompassed emergency treatments. The most frequent indication was an abdominal aneurysm with 72% of cases. In 54% of cases, the aortic diameter ranged 50-70mm. The rates for technical success, over all complications and major complications were 92.8%, 6.7% and 6.0% respectively for all EVAR including emergency indications. In general, EVAR yielded a mortality rate of 1.2% while emergency procedures had a mortality rate of 7.3%. Median dose area product and fluoroscopy time were 10503 cGy × cm2 and 20 minutes respectively at a mean procedure time of 114 minutes. Conclusion Data analysis of the DeGIR quality management system persistently showed a very high technical success rate for endovascular aortic aneurysm repair performed by interventional radiologists accompanied by a low complication rate.
