Stanford classification of aortic dissection
Updates to Article Attributes
Along with the DeBakey classification, the Stanford classification is used to separate aortic dissections into those that need surgical repair, and those that usually require only medical management. The Stanford classification divides dissections by the most proximal involvement:
-
type A: A affects ascending aorta and arch
- accounts for ~60% of aortic dissections
- surgical management
- may result in:
- coronary artery occlusion
- aortic incompetence
- rupture into pericardial sac with resulting cardiac tamponade
-
type B: B begins beyond brachiocephalic vessels
- accounts for ~40% of aortic dissections
- dissection commences distal to the left subclavian artery
- medical management with blood pressure control
In 2014, a special report was published in Radiology 4 that recognised an uncommon form of aortic dissection. The authors describe dissections that originate from the arch or extends proximally into the arch without involvement of the ascending aorta which are not adequately accounted for in the Stanford nor the de Bakey classification systems. Dissections in this region and without involvement of the ascending aorta proximal to the brachiocephalic trunk are managed medically rather thenthan surgically, provided there is no end organ-organ ischaemia. Hence, the authors proposed any dissection originating from the arch between the brachiocephalic trunk and left subclavian artery and not involving the ascending aorta proximal to the brachiocephalic trunk be classified as a type B dissection.
