[Thoracic Endovascular Aortic Repair (TEVAR) Combined with Embolization Technique for Saccular Aortic Arch Aneurysm].

Many of saccular aortic arch aneurysms exist near left subclabian artery(LSA). The thoracic endovascular aneurysm repair( TEVAR) landing on zone 2 is a less invasive and suitable procedure for this type of aneurysm. However, there are several cases with the aneurysm located close to LSA necessitate landing TEVAR on zone 1 or zone 0, otherwise the aneurysm could not be sealed completely. And this procedure seems to increase the invasiveness. In order to complete the sealing of the aneurysm and also keep the less invasiveness, we performed TEVAR using an axillo-axillary bypass or simple occlusion of LSA followed by an embolization using metal coil and NBCA through the catheter which detained in the saccular aneurysm beforehand. We report our experience of seven cases have been successfully treated by this procedure with good results.
