Reimplantation of the largest patent intercostal arteries is usually performed during thoracoabdominal aortic aneurysm repair. This may lead to aneurysmal evolution of the intercostal arteries patch. We report the successful percutaneous endovascular repair in 4 Marfan patients of aneurysms of the intercostal arteries patch that developed after thoracoabdominal aortic aneurysm repair (Crawford type II) during a mean delay of 70 months (range, 48 to 91 months). All patients had previously undergone one or several aortic surgical procedures and had patent subclavian and hypogastric arterial networks. No in-hospital deaths or spinal cord ischemic injuries occurred, which emphasizes the importance of the vascular collateral network.
