Case Rehearsal in 3D Aortic Models Using Prototypes of the Fenestrated AnacondaTM Custom AAA Stent Graft System

T he Fenestrated AnacondaTM Custom AAA Stent Graft System (Vascutek Ltd.) is intended for the treatment of abdominal aortic aneurysms with an insufficient infrarenal landing zone. The endografts are custom made based on high-resolution, 1 mm slice CTA images. The planning and construction of a fenestrated endograft for complex aortic anatomy is critical when exact positioning of the graft is paramount to guarantee cannulation of the aortic branches. For every case, a non sterile prototype, as well as a 3D model, are constructed to allow the engineers, as well as the physician, to “test implant” the device and review the anatomic fit of the graft. Modifications to the initial graft design based on the results of prototype testing help maintain high technical success of fenestrated endovascular repair of pararenal aortic aneurysms.
