The frozen elephant trunk procedure: indications, outcomes and future directions.

ABSTRACT: The treatment of complex multi-segment disease concomitantly affecting the aortic arch and descending thoracic aorta is technically challenging. Until the 1990s, such extensive pathology was addressed by median sternotomy for aortic arch replacement followed by a traumatic thoraco-abdominal incision for reconstruction of the descending aorta as a single- or two-stage procedure. The advent of the conventional elephant trunk procedure by Borst in 1983 simplified the second-stage of this procedure by eliminating the need for clamping of the descending thoracic aorta. However, graft-related complications and the considerable inter-stage mortality were significant limitations associated with the conventional elephant trunk procedure. The emergence of endovascular technology and availability of
