Tips and techniques for optimal stent graft placement in angulated aneurysm necks

An increasing number of patients with severely angulated abdominal aortic aneurysm (AAA) necks are being treated by endovascular aneurysm repair (EVAR). Optimal preprocedural planning and investigation of the AAA morphology is essential to achieve a successful EVAR in these patients. In this article, we discuss specific problems that can be encountered during preoperative planning in relation to periprocedural stent graft deployment in patients with angulated AAA necks and offer potential solutions for these problems.
