Aortic dissection (arịgo) emee Ọtụtụ na ndabere nke ọbara mgbali. Mbelata n'etiti shei (cystic medial necrosis) pụtara na banyere 20% nke ọrịa. Ọ nwere ike so Marfan syndrome.

Ihe ka ọtụtụ ná ndị ọrịa na Marfan syndrome -adịghị ebi ndụ ruo iri afọ anọ.

Aortic dissection (downlink) na-ewe ebe ugboro ugboro esonyere oké atherosclerosis na ọbara mgbali. Na obere okwu, ndị ọnọdụ na-esonyere cystic necrosis (medial).
