Aortic dissection is an emergency and so the patient must be admitted, usually to the ICS.


So-called ''anti-impulse therapy'', involving urgent intravenous antihypertensive treatment to decrease BP and HR (which reduces stress on the aortic wall), is always indicated. This involves [[Beta blocker|beta blockers]] and vasodilators (nitroprusside/nicardipine). The blood pressure should remain < 140/90 for life. Atherosclerotic risk factors should be treated.

Emergency surgery is indicated for Stanford type A dissections, and Stanford type B dissections with complications. Uncomplicated Stanford type B dissections has lower mortality when treated conservatively rather than with surgery.

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.
