Flashcards in Arterial Disease and Aneurysms Deck (12):
1

What is the 5 year survival rate of a patient with a >5cm diameter aneurysms and no surgery?

20%

2

What happens to plaque space after rupture of the fibrous cap?

Fill with blood that can occlude the vessel

3

Why do you get pain in claudication?

Anaerobic respiration due to hypoxia from stenosis

3

What pathological process occurs that allows aneurysms to form?

Weakening of elastin

And eventual failure of collagen

4

What lines the inside of aneurysms?

Thrombus

6

Reduced femoral pulse indicates occlusion where?

Aortic - iliac region

6

At what size is it advisible to surgically intervene with aneurysms?

>  5-5.5cm

7

Why might you not get claudication in tibial/crural disease?

Disease is below branching point for supplying arteries

8

When do you get ischaemic rest pain?

When perfusion is so poor that anaerobic respiration occurs at rest

10

What is the ankle pressure required to occlude pulses in patient with rest pain?

>50mmHg at ankle

11

How are AAA surgically repaired?

Open the dilated aneurysm

Stitch in a dacron tube along the dilated area

Envelope the dacron with aneurysm sack to prevent dacron damaging surrounding tissue 

12

What are the Sx intervention option for claudication?

Angioplasty

Endarterectomy

Bypass
