Aneurysm (Me rn) Flashcards
What is an Aneurysm?
A dilation of the arterial wall
In which arteries can an Aneurysm occur?
Any of them, but the Aortic Aneurysm is the most common
Risk factors of Aneurysm?
Atherosclerosis + male gender + age 65 or older + whites + tobacco use + Peripheral Artery Disease + Hypertension + high cholesterol + Coronary Artery Disease + previous stroke + obesity + trauma
Whenever a dilated arterial wall becomes lined with thrombi, there is a risk of-
Embolization
What meds can be used to treat an Aneurysm?
Simvastatin and/or Doxycycline + Propanol + Captopril
Largest artery in the body =
Aorta
An abdominal aorta would have to be how big in order for it to be considered an Aortic Aneurysm?
Larger than 3 cm
Most important modifiable risk factor for an Aneurysm?
Tobacco
Most common cause for an Aneurysm?
Atherosclerosis
What things make an Aneurysm so deadly?
The sluggish blood flow within the aneurysm may cause a blood clot and they can become Emboli and travel.
They may Rupture with Hemorrhage and Hypovolemic Shock.
Where are most Aneurysm’s located?
Between the Renal Arteries and Aortic Bifurcation
How should you assess for an Aortic Aneurysm (AAA) during a physical assessment?
Auscultate for Bruit, DON’T PALPATE (Can cause a Rupture)
What are the symptoms of AAA?
Often asymptomatic
Deep, diffuse chest pain or angina + Pulsating mass in periumbilical area to left of midline + Bruit over mass + Mid-abdominal or lower back pain (due to aneurysm compression) + Patient states can feel his or her heart beating
How can an Aneurysm be diagnosed?
Physical Exam + X-Ray + MRI + CT Scan
How can an Aneurysm be monitored?
Ultrasound
This is the most accurate way to gauge length, diameter, and presence of an Aneurysm =
CT Scan
The more pain from an aneurysm, the higher the risk for-
Rupture
What’s the main goal of treatment for an AAA?
Prevent Rupture
What diameter of Aneurysm would have conservative treatment?
What diameter of Aneurysm would have aggressive treatment (Surgery)?
Conservative = 5.4 cm or lower
Surgery needed asap = 5.5 or higher
What would Conservative Treatment for a AAA include?
Minimize the Growth of the Aneurysm with meds (Beta blockers, ACE inhibitors, ARBs, Statins, and Antibiotics)
