[Surgical treatment of mega aorta syndrome: a single-center experience].

One-stage total aortic replacement via thoracophrenolumbotomy is safe surgical treatment for mega aorta syndrome, especially in young patients with low surgical risk. Favorable outcomes may be expected in specialized centers with extensive experience in aortic surgery. Compared to staged approach, total aortic replacement eliminates the risks of between-stage aortic rupture. Therefore, it is a worthy alternative to other methods.
