Type I
Dissection originating in the ascending aorta and propagating distally through the aortic arch into the descending aorta (and often beyond) — i.e. it involves all three thoracic segments: ascending, arch and descending. Corresponds to Stanford type A.
CondutaSurgical emergency: open repair with excision of the intimal tear and ascending-aortic (and as needed arch) replacement using a synthetic graft. Medical management alone is inadequate because of the ascending-aorta involvement.
RiscoHigh-risk because of ascending-aortic involvement; in-hospital mortality for type A dissections is about 15-30%, with risk of tamponade, aortic rupture, coronary or cerebral malperfusion and aortic regurgitation.
Dissection originating in and confined to the ascending aorta, not extending into the arch or descending aorta. Corresponds to Stanford type A.
CondutaSurgical emergency, same approach as type 1: excision of the intimal tear and ascending-aortic replacement with a synthetic graft. Ascending involvement mandates operative repair rather than medical therapy alone.
RiscoType A physiology with high early mortality (about 15-30% in-hospital); principal threats are aortic rupture, pericardial tamponade, aortic regurgitation and proximal malperfusion.
Dissection beginning in the descending aorta (distal to the left subclavian artery) and extending distally but remaining above the diaphragm, confined to the thoracic descending aorta. Corresponds to Stanford type B.
CondutaUncomplicated cases: medical therapy first-line, with aggressive blood-pressure and heart-rate control (anti-impulse therapy). Complicated cases (malperfusion, rupture, refractory pain/hypertension): TEVAR stent-graft to seal the entry tear.
RiscoLower early mortality than type A; in-hospital mortality for medically managed type B dissections is about 10-15%. Risk rises with complications such as malperfusion or rupture.

Type IIIb
Dissection beginning in the descending aorta (distal to the left subclavian artery) and extending below the diaphragm into the abdominal aorta. Corresponds to Stanford type B.
CondutaAs for type 3a: medical anti-impulse therapy (blood-pressure and heart-rate control) for uncomplicated disease; TEVAR (or open/branched repair) when complicated by malperfusion, rupture or refractory symptoms. Abdominal extension can complicate stent-graft coverage.
RiscoStanford type B prognosis with about 10-15% in-hospital mortality when medically managed; abdominal/visceral extension adds risk of renal or mesenteric malperfusion.
