Shelly, I would encourage you to get involved with their QI process early (MD's and all endovascular personnel) so you can learn with them - it goes much faster that way. I did publish an article about AAA stent graft assessment by duplex in JVT (JVT 22(2):97-104,1998). It was a research protocol and a bit more detailed than I currently do, but will certainly point you in the right direction. Also, this topic has been discussed on flownet previously so you should check the archives to review everyones comments. I will tell you that it is not as easy as one thinks and it does take a great deal of experience and knowledge of aortic branch vessels and flow. Most of this you can learn from attending case conferences with your MD's when they correlate CT's angios ultrasound. The biggest limitation (next to gas!) is equipment. Very few are capable of delivering the level of sensitivity required to see slow flow leaks in the abdominal cavity. If your system has high quality abdominal color Doppler you should be able to routinely see assessory renal artery branches and hypogastric arteries and an occasional lumbar branch. If your system can not do this I would not recommend examining AAA stents. Gotta run! bj Bonnie L.

We just signed to be a sight for endovascular AAA stent grafts. Our vascular surgeon started putting them in the past month or two. I would like to offer him some kind of post-op scan for monitoring. Any suggestions would be helpful. Shelly Burns LPN, RVT Summa Health System Akron, Ohio 44309
