Type A (ascending involved)
Any aortic dissection that involves the ascending aorta, irrespective of where the primary intimal entry tear is located. By definition these are dissections sitting proximal to the brachiocephalic (innominate) artery; the process may also extend into the arch and descending aorta, but ascending-aorta involvement is what defines type A.
CondutaGenerally treated as a surgical emergency, with urgent open repair (excision of the intimal tear, graft replacement of the ascending aorta, with aortic valve repair/replacement as needed) the usual first-line approach.
RiscoHigh early mortality if untreated — rising roughly 1-2% per hour in the first 24-48 hours and approaching ~50% by the end of the first week. With surgery, reported in-hospital mortality is ~15-30%, with ~70-80% 5-year survival.

Type B (descending only)
Aortic dissection that does NOT involve the ascending aorta. The entry tear and dissection originate distal to the origin of the left subclavian artery and involve only the descending aorta (and beyond), with the ascending aorta spared.
CondutaInitial medical management for uncomplicated cases (anti-impulse therapy: blood-pressure and heart-rate control), with endovascular stent-grafting (TEVAR) or surgery reserved for complications such as malperfusion or rupture.
RiscoUncomplicated type B with medical therapy has ~10-15% in-hospital mortality and ~75-85% 5-year survival; complicated type B (malperfusion or rupture) can exceed ~30-40% in-hospital mortality if not promptly treated.
