Of course we like it. We use it almost every day. IT has much greater utility than other forms of angiography and doppler studies. At the Ben Taub, we are still using one shot emergency center arteriography for all of the indications cited above. The third indication, proximity, is a judgement call and usually not enough by itself.
Some individuals are more liberal with it's use than others.
We also get formal grams frequently and in special circumstances. Some of have a distinct interest advancing the use non-invasive techniques for the evaluation of trauma, but I can't say that we are particularly good at it, yet. For other patients, a good screening tool is the measurement of pressure distal to the injury. If there is systemic pressure, the likelihood of injury is low, and arteriography in any location ED, OR,or radiology will have a low yield. If the patient has a diminshed pressure in the injured extremity, then angiography can be done.
