Through progress in medical imaging, image analysis and finite element (FE) meshing tools it is now possible to extract patient-specific geometries from medical images of, e.g., abdominal aortic aneurysms (AAAs), and thus to study clinically relevant problems via FE simulations. Medical imaging is most often performed in vivo, and hence the reconstructed model geometry in the problem of interest will represent the in vivo state, e.g., the AAA at physiological blood pressure. However, classical continuum mechanics and FE methods assume that constitutive models and the corresponding simulations start from an unloaded, stress-free reference condition.

Abstract OBJECTIVES Our objective was to report the outcomes of fenestrated/branched endovascular aneurysm repair of thoraco-abdominal aortic aneurysms (TAAAs) with endografts. METHODS Between January 2010 and April 2018, patients with TAAAs, considered at high surgical risk for open surgery and treated by Cook-Zenith fenestrated/branched endovascular aneurysm repair, were prospectively enrolled and retrospectively analysed. The early end points were 30-day/hospital mortality rate, spinal cord ischaemia and 30-day cardiopulmonary and nephrological morbidity. Follow-up end points were survival, patency of target visceral vessels and freedom from reinterventions. RESULTS Eighty-eight patients (male: 77%; mean age: 73 ± 7 years; American Society of Anesthesiologists 3/4: 58/42%) were enrolled. Using Crawford’s classification, 43 (49%) were types I–III and 45 (51%) were type IV TAAAs. The mean aneurysm diameter was 65 ± 15 mm. Custom-made and off-the-shelf endografts were used in 60 (68%) and 28 (32%) cases, respectively. Five (6%) patients had a contained ruptured TAAA. The procedure was performed in multiple steps in 42 (48%) cases. There was 1 (1%) intraoperative death. Five (6%) patients suffered spinal cord ischaemia with permanent paraplegia in 3 (3%) cases. Postoperative cardiac and pulmonary complications occurred in 7 (8%) and 12 (14%) patients, respectively. Worsening of renal function (≥30% of baseline level) was detected in 11 (13%) cases, and 2 (2%) patients required haemodialysis. The 30-day and hospital mortality rates were 5% and 8%, respectively. The mean follow-up was 36 ± 22 months. Survival at 12, 24 and 36 months was 89%, 75% and 70%, respectively. The patency of target visceral vessels at 12, 24 and 36 months was 92%, 92% and 92%, respectively. Freedom from reinterventions at 12, 24 and 36 months was 85%, 85% and 83%, respectively. CONCLUSIONS The endovascular repair of TAAAs with fenestrated/branched endovascular aneurysm repair is feasible and effective with acceptable technical/clinical outcomes at early/midterm follow-up.
