Der Chimney-Graft als Alternative zur aortalen Custom-made-Prothese

The chimney graft (CG) in the aorta and the aortic arch is a stent or a stent graft which is deployed in a side branch of the aorta and runs parallel to the aortic stent graft in the aortic lumen or ends protruding over the main aortic graft like a chimney. This technique allows antegrade flow to be maintained in aortic pathologies without sufficient proximal landing zones. This technique can also be used in cases of unintentional coverage of side branches during endovascular treatment.
