Left subclavian artery rerouting and selective perfusion management in frozen elephant trunk surgery.
The frozen elephant trunk (FET) technique enables combined aortic arch and descending aortic repair. We report our experience with a modified arch replacement technique by rerouting of the left subclavian artery (LSA) and fixation of the FET in Zone 2 or proximally under selective perfusion of all three arch arteries and the downstream aorta. ⋯ LSA rerouting facilitates arch aortic repair by FET surgery. The selective perfusion of all arch arteries and the downstream aorta during open arch repair reduces the ischemic times and may improve organ protection.
