RESUMO
We treated a 73-year-old female patient with a giant thoracic proximal aortic aneurysm above a previous multibranched thoracoabdominal graft without a distal neck for a standard endovascular approach. A procedure with sandwich technique was performed using the new Valiant Navion Evo Thoracic Endograft® to preserve visceral graft. Postoperative angio-computed tomography scan demonstrated the correct position of the endoprosthesis without any leakage with patency of visceral graft.

We treated an 89-year-old patient affected by a descending thoracic aorta lesion due to a rib fracture with a penetrating costal stump. An urgent combined thoracic and endovascular surgical approach was performed, removing the rib fragment and positioning an aortic endoprosthesis simultaneously. Postoperative angio-computed tomography scan demonstrated the correct position of the endoprosthesis without any leakage or periaortic hemorrhage.

BACKGROUND: Saphenous vein conduits are still used in a large proportion of coronary artery bypass graft (CABG) operations. A recently commercialized nitinol mesh seems to improve venous graft patency. The aim of this study was to control nitinol mesh vein graft patency in a series of isolated CABG patients by computed tomographic (CT) scan. METHODS: In 25 patients (mean age: 61.0 ± 9.65 years), operated for isolated CABG, the eSVS nitinol mesh (Kips Bay Medical Inc., Minneapolis, Minnesota, United States) was used to wrap one vein graft in each patient. Nitinol mesh vein graft was used to revascularize the right coronary (4 patients; 16%), the posterior descending (18 patients; 72%), and the obtuse marginal (3 patients; 12%) arteries. CT scans were performed at 1, 6, and 12 months postoperatively. RESULTS: The procedure was uneventful in all patients. CT controls showed an overall patency rate of 86.9, 42.7, and 34.1% at 1, 6, and 12 months, respectively. The 4 mm mesh had a significantly higher patency rate at 12 months (83.33%) than the 3.5 mm one which showed quite unsatisfactory results (20%) (p = 0.02). Patients with graft occlusion underwent stress testing which was mildly positive in two cases. One of them underwent a percutaneous revascularization. CONCLUSION: Despite promising early results, use of nitinol mesh for saphenous veins was disappointing in our experience. Further refinements are probably needed.
