What is Commentary to Letter about?
I thank Dr. A-Ching Chao and her coworkers for their comments on our study. I agree that the functional and pathophysiological significance of the valve of the left brachiocephalic vein is not sufficiently studied. The cited anatomical study by suggests little significance, as valves are only found in a minority of these veins, are mainly unicuspid and mostly insufficient. However, functional studies on the competency of these structures are lacking. The issue of a potential barrier to retrograde flow in the brachiocephalic vein further underlines that the appearance of contrast agent caudad to the jugular valve has to be taken into consideration as a criterion of valid insufficiency testing. The note on venous collaterals is important. However, as long as air contrast ultrasound venography (ACUV) is performed properly, venous collaterals do not interfere with insufficiency testing.
