Aortic Root and Distal Arch Management During Type A Aortic Dissection Repair: Expanding Horizons

The management of Type A aortic dissection has evolved over a period of a decade or so, and contemporary reports are suggesting a paradigm shift from a conservative approach to complete excision of the diseased aorta including root and distal arch. Improved cardiopulmonary bypass perfusion techniques, better understanding of the cerebral perfusion, and wide-ranging obtainability of prosthetic conduits gave surgical teams numerous choices. With improving outcomes and maturing surgical techniques, surgeons are performing extensive resections of the diseased aorta, but there is no standard protocol as far as the extent of the proximal and distal diseased aortic tissue resection is concerned. Aortic root replacement is associated with good early-and long-term outcomes and proffered solution in young and stable patients, for that reason many busy centres are endorsing total arch replacement in complex distal aortic dissections. This systemic review is discussing contemporary literature and associated pros and cons during surgical decision-making for these high-risk cases.

Automated summary

With advancements in technology, the management of Type A aortic dissection is shifting towards more aggressive surgical interventions, although there is still no standardized protocol for the extent of resection of diseased aortic tissue.
