Imaging and Surveillance of Chronic Aortic Dissection: A Scientific Statement From the American Heart Association

Abstract: All patients surviving an acute aortic dissection require continued lifelong surveillance of their diseased aorta. Late complications, driven predominantly by chronic false lumen degeneration and aneurysm formation, often require surgical, endovascular, or hybrid interventions to treat or prevent aortic rupture. Imaging plays a central role in the medical decision-making of patients with chronic aortic dissection. Accurate aortic diameter measurements and rigorous, systematic documentation of diameter changes … Show more

“…However, for some patients with type B aortic dissections, the disease presents sufficiently stable for a conservative, non-surgical approach [ 4 ]. In the scientific literature, dissections are referred to as “acute” within 14 days or less after dissection [ 5 ] and as “chronic” if 14 days or more have passed since dissection [ 6 ] with a refined classification distinguishing between a subacute period (15–90 days after dissection) and a chronic phase commencing 90 days after dissection [ 7 ]. Chronic dissections bear an impending risk for worsening and aortic rupture.…”

“…To date there are no published studies focused specifically on small intimal flaps in asymptomatic patients and the natural history and clinical significance of such abnormalities is poorly understood. Given this lack of evidence, clinical management approaches can be highly variable ranging from being ignored to being treated as chronic dissections and surveilled by regular imaging ( 7 ). A recent study of 273 patients with asymptomatic PAUs undergoing imaging surveillance described a very low rate of growth or complications with such lesions ( 8 ), although a study of 315 patients with PAU including those symptomatic lesions described a comparatively higher rate of complications and surgical repair ( 9 ).…”
