PY - 2005 T2 - Principles of Critical Care, 3e AB - Acute aortic dissection occurs more commonly than ruptured abdominal aortic aneurysm.The typical pain, poor peripheral perfusion, and evidence of aortic branch occlusion suggest the diagnosis.Early pharmacologic control of systolic blood pressure and the pulse wave (dP/dT) is imperative.Investigations must be undertaken urgently to confirm the diagnosis and direct definitive treatment.Emergency surgical repair is indicated for type A dissections.Control of hypertension is important to minimize complications and maximize survival both in the postoperative period and in the long term.Type B dissections may have a more ominous prognosis than previously thought and require very close long-term follow-up.
