These sounds may be normal, innocent findings (i.e., a venous hum in a child) or may point to underlying pathology (i.e., a carotid artery bruit caused by atherosclerotic stenosis in an adult). Head and neck bruits loom especially important today because physicians encounter arterial occlusive disease more frequently as a greater proportion of our population lives longer.]

Well clearly the Dr here is putting the MRA finding of a compressed subclavian artery together with the thrill and bam...not an innocent finding.
I've read that determining the severity of the situation by pressing on the thrill is art more than science. It's easy to misinterpret. Thus, the additional tests.
If anyone else had / has a bruit I'd be interested to here how this finding was linked to other TOS symptoms.
