[Chimney technique--stent implantation to the left common carotid artery in patient treated with thoracic aortic stentgraft].

Proximal fixation is often limiting for endovascular thoracic aortic aneu. rysm repair and the stentgraft may need to cover the origin of the arch branch vessels. Chimney technique have been proposed to preserve flow into over stented branches during or after stent graft implantation. The aim of this report is to share our initial experience of this technique.
