Arteriofemoral_bypass

A 67 year-old female with rest pain and calf claudication at 20 feet with a past medical history significant for peripheral vascular disease (ankle brachial index 0.50 bilaterally), chronic obstructive pulmonary disease, nicotine abuse, and cerebral vascular occlusive disease (60% carotid stenosis) was studied. Noninvasive imaging was consistent with atherosclerotic occlusive disease of the iliac and femoral arteries bilaterally. Imaging data was acquired preoperatively to obtain geometric information (using MRA) of the aorto- iliac-femoral system. Approximately two weeks after the acquisition of the preoperative data the patient underwent an end-to-side aorto-femoral reconstruction. A Dacron bypass graft with nominal dimensions of 14 mm x 7 mm was used. Postoperative image data was acquired approximately 6 months after the operation.

Palmaz-stent

The geometry of this stent is built using standard dimensions available in literature. The geometry is similar to a five-ring Palmaz-Schatz stent. The expanded geometry is taken from a pressure-driven expansion using a large-displacement, large-strain, elasto-plastic analysis using ABAQUS.

Virtual Aorta 1

This model is constructed using two different datasets from two different subjects; one dataset of the thoracic aorta and one dataset of the the abdominal aorta including some parts of the iliacs. The solid models from the two datasets are scaled and modified to obtain a reasonably accurate solid model of the full aorta.
