Current knowledge on E-vita abdominal endograft.

ABSTRACT

The field of endovascular abdominal aortic repair has changed remarkably compared to what it was prior to 1993, the year of the first commercial endograft deployment in the United States. Over the years of endovascular aneurysm repair experience, various companies have attempted to construct an ideal stent-graft for exclusion of an abdominal aortic aneurysm (AAA). However, it has become evident that not all abdominal aortic anatomies are amenable to endovascular treatment and that the rationale "one device fits all AAAs" can lead to disastrous results. Different endografts have dissimilar properties and characteristics. Type of graft material, configuration and type of stent structural support, modularity, type of transrenal fixation, are potentially influential factors of endograft behavior. The self-expanding E-vita abdominal stent-graft (JOTEC, Hechingen, Germany) is a relatively new infrarenal, modular stent-graft with suprarenal fixation designed for AAA reconstruction. The present paper analyzes the technical characteristics and properties of this device. We also analyze our experience with the endoprosthesis and review the current literature.
