Thoracic endovascular aneurysm repair in Japan: Experience with fenestrated stent grafts in the treatment of distal arch aneurysms

Custom-designed stent grafts for thoracic endovascular aneurysm repair. Endoprostheses for treating distal arch aneurysms should have fenestrations to preserve blood flow into the arch vessels.

Angiograms show placement of two stent grafts away from the ascending aorta, with preservation of blood flow into the arch vessels through the fenestrations in the device. A, Predeployment image. B, Image obtained after deployment of the first stent graft. C, Image obtained after deployment of the second stent graft.

Computerized tomography scan shows total exclusion of a distal arch aneurysm, with no endoleaks. A customized fenestrated stent graft was used.
