"Exploring the boundaries of endovascular aneurysm repair: studying an all-comers population"

An abdominal aortic aneurysm can be treated endovascularly since the early 1990s. In the endovascular technique, a stent is placed through the groin, which is less invasive than the open technique. An important limitation is that ruptured and complex aneurysms are less suitable and more long-term complications are seen. With the help of registration studies, this thesis investigated how stents function at the extremes of the manufacturers' instructions for use. The thesis shows that in the case of ruptured aneurysms, the technical results are good. Additionally, it is shown that in complex aneurysms the short-term number of complications is not unacceptable, despite the challenging anatomy. The long-term results will have to be determined in the future. The above results can contribute to determining the optimal treatment strategy of ruptured and complex aneurysms.
