Aneurysmal Disease Flashcards
(28 cards)
What are some common areas for aneurysm?
Brain Carotids Thoracoabdominal Aorta Peripheral vessels splanchnic vessel
T or F: aneurysm have all layers intact
T
Which aneurysm looks like a football or balloon?
fusiform shape
What presents with a Popliteal and femoral aneurysms?
Popliteal and femoral aneurysms usually present with emboli or thrombosis rather than ruptured.
Which aneurysm can be a complication of aortic dissection?
Thoracoabdominal Aneurysm
How does aortic dissection occurs?
Shear forces on the arch leads to tears through the intima and into the media.
T or F: false aneurysm are pulsatile and have no true layer
T
What is the most common cause of aneurysm?
Genetic disposition to degenerative forces
What are some infectious causes of aneurysm?
Chronic mycotic aneurysms (eg. Syphyllitic) or acutely supprative (Staph.)
What are some congenital causes of aneurysm?
Marfan’s, Ehlers-Danlos
Where do mechanical aneurysm occur?
subclavian
T or F: Marfan syndrome is autosomal recessive?
F: autosomal dominant
What happens in Marfan syndrome?
Defect in the cross-linking of collagen due to mutations of type I procollagen.
Which type of Ehlers-Danlos Syndrome have increased risk for aneurysm?
E-D Type IV is the “arterial-ecchymotic” type (collagen type III)
What are the majority of aneurysm?
cerebral and infrarenal aortic
What is the classical triad in abdominal aortic aneurysm (AAA)?
1) acute abdominal or back pain
2) hypotension
3) pulsatile abdominal mass
(usually presentation does not have all three)
T or F: AAA affects more so in males
T
Non-ruptured AAA presentation:
Inflammatory
Symptomatic or tender AAA
Contained rupture (false aneurysm)
T or F: most patients have calcium deposit at the wall of their aneurysm
T
What is mural thrombosis?
Very stable mass of debris, dead cells, fibrin, few red cells.
T or F: anticoagulation is needed for mural thrombosis
F:
It does not usually embolize, will occasionally liquefy and shift. You do not anticoagulate.
T or F: angiogram is usually important for imaging aneurysm
F:
CT, Xray, ultrasound
What is the Szilagi Curve?
Describe the 5 year risk of rupture in relation to the diameter of the aneurysm (greater than 4 cm…80% at 6cm)
T or F: the aneurysm grows each year
T: .4 TO .5 CM/YEAR
