For all abdominal aortic aneurysm endografts, the major challenge is minimizing the risk of a type I endoleak. Percutaneous placement of an abdominal aortic endograft has become a widely-performed procedure. With several devices available on the market, there are many device-specific and experience-based considerations in planning and performing these procedures safely and with good outcomes. Although not always evidence-based, reviewing some case-specific scenarios can introduce techniques or lead to standards of practice that reduce suboptimal outcomes or prevent complications in future procedures. This chapter discusses deployment finesse of the Cook Zenith Flex and Zenith LP stent grafts, but many of the described concepts apply to other abdominal endografts and even thoracic endograft procedures.
