Branched devices for thoracoabdominal aneurysm repair: Early experience

A, Branched stent graft with one free-flow stent, one internal sealing stent, followed by reducing stents, from which emerge the proximal side branch. B, Detail of the emergence of the side branches from the main stent graft module. C, Iliac side branch device.

Distribution of the side branches (SB) in the first 21 stent grafts planned, relative to their clock position.

A three-dimensional computed tomography angiography reconstruction shows a thoracoabdominal stent graft with four branches, in adjunct to left internal iliac artery revascularization with iliac side branch device and contralateral embolization of internal iliac artery.
