Conclusion
Current literature seems to suggest that Z-0-FET procedures are more
straightforward and associated with lower rates of certain adverse
events, however, the majority of data reviewed is retrospective. This
review therefore recommends prospective research into the comparative
strengths and limitations of Z-0-FET and Z-2-FET to better substantiate
whether proximalisation of arch repair represents a concept, or a true
challenge to advance surgical intervention for arch pathologies.
