Now I'm confused as to what you're actually attempting to do... The wording above makes it sound as though you're trying to extract a variable name from a declaration with one pattern, then find its usage later in the file with another pattern. The patterns themselves, however, aren't consistent with this interpretation, as both match the variable type. Perhaps it would help if you clarified exactly how you're using the 2 patterns above...
