Thoracic aortic lesions treated with the Zenith TX1 and TX2 thoracic devices: Intermediate- and long-term outcomes

Overall mortality (thick line) and aneurysm-related morality (thin line) were assessed using a Kaplan-Meier analysis, and the error bars denote the 95% confidence intervals (CI).

Freedom from secondary intervention is shown in 160 patients with >72 months of follow-up.

A, Kaplan-Meier life-table analysis shows of freedom from primary endoleak and (B) secondary endoleaks.

A, A three-dimensional (3D) reconstruction of a computed tomography (CT) scan demonstrates an endovascular completion of an elephant trunk graft. The pacer wire attached near the distal end of the elephant trunk graft is indicated by the small arrow. Distally, the device was deployed into an aneurysmal segment that had been wrapped with a polyester strip to create a landing zone in a patient deemed unable to tolerate an open thoracoabdominal repair (large arrow). B, Same patient, 3D reconstruction CT scan at the 6-month follow-up demonstrates a stable proximal dense position (arrow) enlargement of the wrapped segment, distal endoleak, and proximal migration (circle) of the distal stent through the wrap and into the aneurysm. Note, no barbs were used on the distal fixation system for fear of injury to the abnormal aorta below the level of the stent graft. C, Magnified view of previous image demonstrates scratches on the external aortic wall (arrows) caused by migration of the device.

A and B, Radiographs in different projections demonstrate a single barb fracture (circle and arrow) first noticed at 2 years follow up.
