Clinical Outcomes of Contemporary Frozen Elephant Trunk Prostheses and the Ascyrus Medical Dissection Stent in Aortic Arch Surgery: A Systematic Review and Proportional Meta-Analysis

Introduction

The frozen elephant trunk (FET) technique is an established strategy for complex aortic arch and descending thoracic aortic pathology. Several covered FET prostheses are available, while the Ascyrus Medical Dissection Stent (AMDS) represents a distinct uncovered hybrid arch adjunct used principally during open repair of acute type A dissection. This systematic review evaluated the reported clinical and aortic outcomes of contemporary FET prostheses and the AMDS.
