Sounds like phylloxera galls, although they are usually on the underside of the leaves. The leaf galls are usually not a problem on Catawba, which is only mildly susceptible.
Did they look like this? http://www.ppdl.purdue.edu/PPDL/images/grape_phyllox-leaf_abax.jpeg

Subject: [NAFEX] Grape vine attachments
My Catawba grape vine appears to be healthy but new leaves have 1/2cm long vertical soft budlike attachments on the upper surface. Looking through a loupe they appear green with red streaks. I cut one open to find that it is hollow inside. No insect activity is apparent. I have looked through some books including "The Grape Grower" and cannot find any such description. I am located in SW Tennessee. Does anyone have any thoughts on what they might be and any suggestions of what if anything I should do? If they are harmful I would like to control them with the least toxic means. If they are beneficial I would like to encourage them.
