TYPES OF AORTIC ANEURYSMS
•
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.
