Ok, now let us make a few comments based upon your responses.
1.  To go directly from an abnormal ABI to angiography would be justifiably criticized.  Much like proceeding directly to mastectomy after feeling a lump in the breast.  Now, if there are no pulses, a cold foot , and a necrotic toe, . . . then that is something else.
2.  The other responders are quite right, . . . it is a long running debate about duplex testing vs physiologic testing and which is better under what circumstances.  I personally like segmental pressures with PVR's before and after exercise.  Other people hate that and prefer other testing.  Hopefully your physician is exercising good clinical judgment and is not just ordering testing indiscriminately and wasting your resources.  Whether your testing is unnecessary or not should be addressed with follow-up and comparisons with angiography, etc.  The stuff we all do for continuing quality improvement.

Subject: Lower Extremity Duplex

Can the Flownet members please let me know when and where it is appropriate to duplex lower ext. native arteries? I am working with a physician who is ordering them on every patient with any abnormal ABI result's. It seems like I am doing unnessecary procedure's and I can not find any protocols listing appropriate testing parameters.

                Thank you for your help!
