Keeping values throughout conversion from raster to polygon

Hi all,
What I need to do is calculate the catchment size of about 300 pourpoints and join the tables afterwards, so that each pourpoint can be related to its catchment. What I have done so far is creating the catchments as rasters and converting them to polygons to get the size of the area. Doing so, I lost the values in the attribute table that would have determined the relationship between pourpoints and catchments.
Renaming all 300 catchments manually doesn't seem like an adequate option. Is there a way to keep the significant values throughout the conversion to polygons or an even simpler solution?
Your help is much appreciated.
