• Abdominal ultrasound can detect and monitor the progres- sion of AAA. Treatment A dissecting aortic aneurysm is an emergency that requires prompt surgery and stabilizing measures. Treatment includes: • antihypertensives such as nitroprusside

• negative inotropic agents to decrease force of contractility • beta-adrenergic blockers • oxygen for respiratory distress • opioids for pain • I.V. fluids • possibly, whole blood transfusions. Treatment of stable AAA focuses on surveillance and tight BP control to prevent enlargement.
