CME TEST QUESTIONS: JULY 2012

Examination available at http://learn.sirweb.org/. To take the online JVIR CME tests, please log into the SIRLearning Center with your SIR user name and password. Nonmembers: If you do not already have an SIR username andpassword, please click on “Create an Account” to gain access to the SIR Learning Center. Once in the Learning Center,click on the “Publication” activity type for a listing of all available JVIR CME Tests. Each test will be available onlinefor three years from the month/date of publication.

The CME questions in the July issue are derived from the article “Evaluation and Treatment of Suspected Type IIEndoleaks in Patients with Enlarging Abdominal Aortic Aneurysms” by Funaki et al.

1. For this study, the authors define sac enlarge-ment as:a) More than a 5-mm increase in the largest axial

sac diameter compared to that on the most recentprior CT.

b) More than a 5-mm increase in the largest axial sacdiameter compared to that on the immediate post-procedure CT.

c) More than a 5% increase in the largest sac diameteralong the aortic centerline compared to that on themost recent prior CT.

d) More than a 5% increase in the largest sac diameteralong the aortic centerline compared to that on theimmediate postprocedure CT.

2. With regard to technical successes:a) Transarterial embolization had better success than

direct aneurysm puncture.b) Direct aneurysm puncture had better success than

transarterial embolization.c) Some technical successes were clinical failures.d) Some technical failures were clinical successes.

3. An encouraging, but unexpected finding noted by theauthors was:a) Pre-procedural CT well predicted treatment success.b) The endoleak feeding artery was usually easily

identified on the planning CT.c) Type III endoleaks, which were detected after

treatment of suspected type II endoleaks, were alsoincidentally successfully treated.

d) Unsuspected type I endoleaks were easily treatedconcomitantly during transarterial embolization oftype II leaks.

4. Reasons why endoleaks may have been misclassifiedinclude all of the following EXCEPT:a) Findings of different types of endoleaks may have

similar findings on CT.b) Type II endoleaks are much more common than

other types.c) Even with angiography, type II and type III en-

doleaks may be indistinguishable.d) Focal type I endoleaks may mask concurrent type

II endoleaks.
