  • Post Test Questions


    1.  Which of the following requires emergent endovascular treatment?
    1.   Asymptomatic celiac artery dissection
    2.   Gastroduodenal artery pseudoaneurysm measuring 1 cm in setting of pancreatitis
    3.   Incidental 1.5 cm splenic artery aneurysm
    4.   Acute renal vein thrombosis

    2.  A patient who presents with an acute renal infarct and distal SMA embolism most likely has which of the following?
    1.   Right ventricular thrombus
    2.   Renal cell carcinoma with tumor thrombus
    3.   Left ventricular thrombus
    4.   Concomitant primary occlusion of both the renal artery and SMA

    3.  Which of the following indicates rapid enlargement of an atherosclerotic abdominal aortic aneurysm?
    1.   2 mm increase in 6 months
    2.   5 mm increase in 6 months
    3.   5 mm increase in 12 months
    4.   7 mm increase in 12 months

    4.  A penetrating aortic ulcer is distinguished from a non-penetrating ulcer by
    1.   Presence of associated intramural hematoma
    2.   Size > 5 mm
    3.   Extension into the internal elastic lamina
    4.   A and C

    5.  Type II endoleaks following abdominal aortic endovascular stent repair
    1.   Are always interventional emergencies
    2.   Most commonly arise from the superior mesenteric artery
    3.   Occur at the proximal or distal end of the stent
    4.   May resolve without intervention

    6.  With respect to surgical grafts, which of the following is false?
    1.   More likely to be complicated by aortic rupture than endovascular stents
    2.   May dilate up to 30% as a normal finding
    3.   Will experience 100% polyester degradation by 40 years
    4.   May be complicated by anastomotic pseudoaneurysm
