Mid-to-long-term outcomes of the frozen elephant trunk procedure in aortic pathology: a systematic review and meta-analysis.

ABSTRACT:

Background

The frozen elephant trunk (FET) provides single-stage repair of complex, concomitant aortic arch and descending aortic disease, integrating both conventional and endovascular approaches. While multiple meta-analyses affirm short-term safety, long-term outcomes remain largely unknown, especially regarding overall survival and freedom from re-intervention. This current systematic review and meta-analysis aims to summarize the short- and long-term outcomes following the use of FET in aortic pathology.

Methods

Studies with at least two years of follow-up data on FETs were identified in five electronic databases, which were searched from inception of records until July 2025. The primary outcome of interest was mortality, with short-term data presented as either 30-day
