1. A method of anatomic classification of aorta anatomy in aortic aneurysms to determine a number of seal segments between the aorta and an endograft implanted within the aorta, the method comprising:
accessing an image of an aorta;
analyzing the image to identify a point of divergence of the aorta and one or more additional points of reference of the aorta, the point of divergence defined as a point along a centerline of the aorta where a contour of the aorta changes from a cylindrical or conical shape to a reverse conical shape, and the one or more additional points of reference including a location of a lowest preserved branch vessel and a location of where a proximal end of an endograft would be upon implantation within the aorta;
measuring one or more longitudinal distances along the centerline of the aorta between the point of divergence of the aorta and at least one of the one or more additional points of reference; and
classifying the aneurysm based upon the measured distances to determine a number of seal segments between the aorta and the endograft upon implantation within the aorta;
wherein, when the location of the proximal end of the endograft is proximal to both the point of divergence and the location of the lowest preserved branch vessel, there are three possible seal segments between the aorta and the endograft upon implantation within the aorta;
wherein, when the location of the proximal end of the endograft is proximal to only one of the point of divergence and the location of the lowest preserved branch vessel, there are two possible seal segments between the aorta and the endograft upon implantation within the aorta; and
wherein, when the location of the proximal end of the endograft is distal to both the point of divergence and the location of the lowest preserved branch vessel, there is one possible seal segment between the aorta and the endograft upon implantation within the aorta.
