New developements in endovascular infrarenal aortic aneurysm treatment

Clinical/methodical issue. New technical developments in endovascular aortic repair (EVAR) have broadened the range of patients eligible for minimally invasive aneurysm treatment. Optimization of delivery sheaths and catheters by considerable downsizing of diameters, increase of pushability and stability combined with flexibility are important parameters. Performance. Especially patients characterized by small and tortuous iliac access vessels can nowadays be treated by EVAR. Ease and effectiveness of applicability guarantee safety and quality improvement, which results in better treatment of patients. Progress in stent-graft design with integrated options for repositioning, active positioning and aneurysm sealing facilitate treatment of angulated vessel segments or hitherto unsuitable sealing zones. Practical recommendations. Interventionalists have to be familiar with all available stentgraft materials and techniques. Profound knowledge helps to choose the bestmaterial for a patient's individual anatomy, confident application and long-termsatisfactory results.
