Study Notes

Symptoms

Dull, vague pain in abdomen, back, or flank
Can be acute and severe in ruptured AAA
Sensation of pulsatile mass in abdomen
Hypotension, often manifesting as syncope
Occurring in cases of ruptured AAA
Diminished femoral pulses
"Blue Toe" Syndrome
Duodenal obstruction, leading to vomiting and weight loss
Due to microemboli from aortic thrombus
Vertebral body erosion leading to severe back pain
Best place for AAA rupture is often in the posterior (back) to tamponade and hold internal pressure

Associated Complications

Occurring in cases of ruptured AAA

Where is the best place for a AAA to rupture?

Best place for AAA to rupture is in the back or posterior because it can tamponade and hold pressure on itself. If it ruptures anteriorly, the outcome is typically fatal.

Treatment: Medical Management

Control hypertension
Quit smoking
Control other risk factors
Could give a STATIN and/or an ACE inhibitor (beneficial)
Monitoring small aneurysms (4.0 - 5.4) with ultrasound or CT (every 6-12 months)
Monitoring aneurysms smaller than 4.0 (every 3 years)
Open repair is more challenging for patients, with cross-clamping, requiring monitoring of kidney function, urine output, pedal pulses, and extremity movement.
Keeping the patient stable and preventing further issues (blood clot formation or graft rupture)

Additional Notes

Monitor neurologic status, peripheral status, and renal perfusion status.
Grey Turner's sign: flank ecchymosis (bruising)
Severe back pain.
