48. Surveillance of EVAR patients can be performed accurately, safely, and cost- effectively with DU as the sole imaging study. J Vasc Surg. 2009 Nov ; 50 ( 5 ): 1019 - 24 Despite its low positive predictive value, we found DU to be a sensitive test for the detection of clinically significant endoleaks. Given concerns about cumulative radiation exposure and cost, and the surprisingly low sensitivity of CTA for endoleak detection in this series, selective CTA based on DU surveillance may be a more appropriate long-term strategy . J Vasc Surg. 2009 Jan;49(1):60-5 . CDU only surveillance post-EVAR is safe and can be initiated early after treatment in patients with shrinking or stable aneurysms. This policy should result in cost savings advantage and avoid the complications associated with CT. J Vasc Surg. 2009 Apr;49(4):845-9 CDU imaging has a high sensitivity in detecting endoleaks requiring intervention , is better at identifying the type of endoleak , and is an excellent test for graft surveillance after endovascular aneurysm repair. Compared with CT scan, CDU imaging in our experience is the preferred test on which to base an intervention for endoleak. J Vasc Surg. 2009 Nov;50(5):1012-7

50. the recent document on training for cardiology fellows, COCATS-2, has recommended 2 months of dedicated or aggregate instruction in the noninvasive laboratory for Level 1 training in vascular Ultrasound. Beller GA, Bonow RO, Fuster V. ACC revised recommendations for training in adult cardiovascular medicine: core cardiology training II (COCATS 2) (revision of the 1995 COCATS training statement).
