What is amaurosis fugax
Occlusion of the ophthalmic branch of the ICA, shade coming down over the eyes
|
What is Factor V Leiden
The most common congenital hypercoagulable disorder
|
>5.0cm in women, >5.5cm in men, increase >0.5cm/yr
(>6.5cm if open repair needed)
Indications for asymptomatic AAA repair
|
What is hypertension
Most important risk factor for stroke
|
What is smoking
The most common acquired hypercoagulable disorder
|
Ax-bifem bypass, removal of infected aortic prosthesis and oversewing of aortic stump several days later
Standard treatment for pt with infected aortic graft
|
What is symptomatic > 70% stenosis, asymptomatic > 80% stenosis
Indications for CEA
|
aortoenteric fistula
Hematemesis in patient with history of AAA repair
|
|
Hypoglossal
Glossopharyngeal Vagus is most commonly injured -> hoarseness
Cranial nerves at risk during CEA
|
artery of Adamkiewicz, intercostal arteries -> spinal cord ischemia
Covering this artery during descending aortic repair leads to paraplegia

What is
I - Luminal irregularity or a dissection/intramural hematoma with <25% luminal narrowing II - Dissection or intramural hematoma ≥25% luminal narrowing III - pseudoaneurysm IV - occlusion V - transection with extrav
BIFFL grades
|
Type I - proximal or distal graft sites
Type II - collateral flow into aneuryms (i.e. lumbars) Type III - overlap sites Type IV - graft porosity Type V - "endotension" - expansion of aneurysm without evidence of leak
Type of endoleaks
