Beschreibungen/Notizen

• Endovascular aneurysm repair (EVAR) has transformed aortic surgery since its first description in the early 1990s. With advancements in endovascular techniques, most of the complications associated with EVAR are successfully managed with catheter-based means, but certain circumstances may arise that mandate explantation and conversion to open abdominal aortic aneurysm (AAA) repair. According to a meta-analysis, an average of 1.5% and 1.9% of patients undergoing EVAR require early or late conversion, respectively. The most frequent reasons for early conversion are problems with access, technical failure of graft deployment, vessel rupture, inappropriate endograft placement, and graft kinking or thrombosis. One of the most vital components for the safe removal of an endograft is control of the proximal aorta. Endograft removal is the most challenging part of the procedure. Although complete removal of the endograft is sometimes necessary, preservation of functional graft components is frequently possible.
