Standard and Fenestrated Endograft Sizing in EVAR Planning: Description and Validation of a Semi-automated 3D Software

An abdominal aortic aneurysm (AAA) is a pathological condition consisting of an abnormal dilation of the abdominal aorta, exceeding more than 50% its normal diameter [8]. Aneurysms tend to grow, and eventually may rupture, with a high mortality rate. Elective surgery is usually performed when the diameter exceeds 5.5cm [16]. The traditional surgical approach based on an open repair, has been steadily substituted by the endovascular aneurysm repair (EVAR), a minimally invasive technique involving the deployment and fixation of a stent graft that excludes the damaged wall from circulation.
