UI:712 - Aortic dissection, cystic medial degeneration
The histologic reaction in the adventitia to aortic dissections may be relevant to dating the onset of symptoms and to providing insight into pathogenesis.
Adventitial inflammation is prominent soon after intimal injury in aortic dissections before rupture of the false lumen. The pattern of inflammation is distinct from aortitis and can be used to date early aortic dissections.
