Management of chronic Stanford type A aortic dissection combined with Neri type C coronary occlusion: a case report and literature review Open

Tiansheng Tang, Ziao Wang, Wei Zhou, Hai Wang, Hanjun Zhang , et al. · 2023

While there are many reports on partial aortic root remodelling, it is rarely performed for chronic aortic dissection of the coronary artery. This case report describes a 71-year-old male patient with chronic aortic dissection who was admi…
