Endovascular repair for three-channelled aortic dissection.

Surgical repair of extensive thoracic aortic disease induced by repeated aortic dissection is challenging due to its invasive nature in some cases. We report a rare case of successful endovascular repair of a dissected 3-channelled thoracic aortic aneurysm using the PETTICOAT (provisional extension to induce complete attachment) technique and false-lumen embolization (the candy-plug technique). The PETTICOAT technique improved visceral flow, and the false lumen of the aneurysm was completely thrombosed by the candy-plug technique. This minimally invasive combination technique might be a good option for the treatment of complex dissected thoracic aorta.
