Flashcards in PVD: Aortic. PAD Deck (34):
What diameter Ao is considered a AAA?
>3cm or 50% inc in size c/w prox segment
Most common site for thoracic Ao aneurysm?
Desc thoracic Ao
Timing of Ascending TAA repair
>5.5cm for most patients
>4.5cm for bicuspid AV, Marfans or Ehlers-Danlos
Timing of descending TAA repair
Can you do endovascular repair for an ascending Ao aneurysm?
Surgical morbidity for descending TAA repair
Is open surgery or endovascular preferred for AAA repair?
What is difference in mortality b/w endovascular or open AAA repair? Morbidity?
Lower morbidity with endovascular
Timing of repair of AAA
What to do with pt with AAA 4-5.4cm?
U/S or CT every 6-12 months
What to do for pt with AAA <4cm?
U/S every 2-3 yrs
When do you repair a AAA regardless of diameter?
Guidelines for management of AAA
4cm- U/S every 2-3 yrs
4-5.4cm- U/S or CT every 6-12months
Any sxs = repair
USPSTF recs for AAA screening
Screen any man age 65-75 who ever smoked
No routine screening for women (even with family hx)
When can you screen a person for AAA if they have a first degree relative with AAA?
When it is a MAN 60 yrs old or older (not women)
When do you intervene on a lower ext aneurysm?
Where are lower ext aneurysms most commonly found?
50% rule for lower ext. aneurysms
50% assoc. w/ AAA (should screen)
What to do if a pt has lower ext aneurysm?
Imaging of contralateral ext and AAA screen
If lesion >2cm, repair
If lesion <2cm, annual imaging
Which medication increases functional capacity in claudication?
How to calculate ABI
Take ipsilateral Highest ankle pressure. Divide it by HIGHEST brachial pressure on EITHER side.
What is a normal ABI?
What is an abnormal ABI?
ADA rec for screening diabetics for PAD
Do ABI in diabetics > 50 y/o, if normal, repeat in 5yr
What med can you use for an asymptomatic pt with PAD?
Class I recs for patients with PAD
Antihypertensives, DM, smoking cessation
High dose statins
Do you use DAPT for PAD?
No. Single therapy.
When do you use Plavix in PAD?
As alternate to ASA

What is the blackboard warning for cilostazol
Do not give in CHF
What is the class of recommendation for prophylactic endovascular intervention on an asymptomatic pt with lower ext PAD?
When can you do intervention on PAD?
Sxs are LIFESTYLE limiting AND inadequate response to exercise and meds and favorable risk of procedure.
