Aortic dissection is problematic because it may rupture the aorta, or it may cause downstream ischaemia. If the dissection occurs above where a branching artery originates, the branching artery will no longer be supplied by blood from the true lumen but rather from the false lumen. Circulation in the false lumen is worse than in the true lumen or even completely absent, which may cause ischaemia of supplied tissues. Thrombi may also form in the false lumen, which may embolise. | Aortic dissection is problematic because it may rupture the aorta, or it may cause downstream ischaemia.

Surgery involves the replacement of the affected part of the aorta with a prosthesis, or the insertion of a stent graft, or a combination of the two. An affected aortic valve must be replaced. | Surgery involves the replacement of the affected part of the aorta with a prosthesis, or the insertion of a stent graft, or a combination of the two.
