Reconstruction of the left subclavian artery in arch repair: An end-to-side anastomosis technique

In total arch replacement, using frozen elephant trunk (FET) or elephant trunk techniques ensures proximalization of the distal anastomosis. However, in some cases, the left subclavian artery (LSCA) is deeply located and difficult to visualize. Therefore, surgeons face technical challenges during the LSCA reconstruction. We report an end-to-side anastomosis technique that enables safer and easier anatomical reconstruction of the LSCA.
