Flashcards in Chap 139 LE aneursyms Deck (28):
How often is FA aneurysm bilat?
Other associated aneurysm?
25% if true aneurysm (most False)
What diseases are associated with FA aneurysm?
degenerative, Behcet, parkes weber, wegners
How often to pseudoaneuryms of FA occur with diagnostic and therapeutic interventions?
When to intervene?
What does false aneurysm look like on US?
to and fro (ying-yang)
What are therapeutic options for false aneurysm?
US guided compression
10-20 minutes, bedrest 6 hours
can be as good as US guided
US guided thrombin injection
success reaching close to 100%
open surgical repair
What is normal diameter of popliteal? what is aneurysmal?
1.5 times the normal segment diameter (>1.5-2)
How common are popliteal aneurysm? how many bilat? how many have AAA
most common peripheral aneurysm but still rare
How do they present?
Which is most common presentation?
chronic ischemia (claudication)
compressive (vein, nerve)
lower limb ischemia
How do you treat endovascular?
LZ 2 cm
How to treat open?
What is the difference between open and endo?
similar but reintervention rate higher in endo
5yr patency 70%, 80% if add plavix
What are advantages/disadvantages of medial/posterior approach?
What is a persistent sciatic artery aneurysm?
what % anerysmal
what artery hypo plastic?
What do you pay attention to when operating?
rare anomaly prone to aneurysm
40% become aneurysm
large buttock mass,
local compressive symptoms, distal ischemia
avoid sciatic nerve (so don't expose the artery surgically)
What is the most common peripheral aneurysm?
How many PA have coexisting AAA?
What are CSVS recommendations for screening in PA?
screen for AAA
screen for contra PA
How many PA are bilateral?
What structures pass through the adductor hiatus?
superficial femoral artery
superficial femoral vein
saphenous branch of descending genicular artery
Name 6 non-atheromatous causes of IC?
Pop entrapment syndrome
Adventitial cystic disease
Chronic compartment syndrome
Kinking/endofibrosis of iliacs
Thrombosis of persistent sciatic artery
What are indications for treatment of PA?
presence of aneurysm (low risk procedure)
>3.0 (if asympto)
Between what two muscles is the popliteal vessels found in the infrageniculate medial approach?
In posterior approach, which side is the upper portion of the S incision directed?
What are three nerves encountered in the posterior exposure
medial sural nerve
Which patients to consider for thrombolysis with PA thrombosis?
patients without motor loss
patients with no distal runoff
How do you mix cathflo?
10mg in 1L of NS
What is risk of ICH with thrombolysis?
