Joanna Kee-Sampson MD, Presenter: Nothing to Disclose

Aaron Himchak MD, Abstract Co-Author: Nothing to Disclose

At the conclusion of this exhibit, the viewer will: 1) Be able to detect and differentiate the various types of endoleaks on CT angiography and conventional angiography. 2) Have a basic understanding of the procedural aspects of endoleak repair and be familiarized with post-repair results. 3) Have an understanding of the surveillance of endoleaks.  

This will be presented in a quiz format: 1) Brief background on endovascular aneurysm repair (EVAR). 2) Introduction of endoleaks (clinical significance, natural history, risk factors) 3) Diagnosis and clinical surveillance of endoleaks (CT, CTA, duplex ultrasound) 4) Types I-V endoleaks will each be discussed in terms of: a. Definition b. Specific imaging findings (CTA, antiography) c. Repair of each type of endoleak                    i. Type I and III (balloon dilatation, relayering endograft, extending endograft, endoanchors)                    ii. Type II (embolization)                    iii. Type IV (self-limited)                    iv. Type V (treatment controversial, will present literature review) 5) Follow-up of endoleaks post repair
