You can build a pattern from array 1 and find all matches in array 2: 
#!/usr/bin/perl
use warnings;
use strict;
use Data::Dumper;

my @array1 = qw(234 453 111 239);
my @array2 = qw(v204_txt v234_txt v450_txt v453_txt);

my $pat = join '|', map quotemeta, @array1;

my @array3 = grep /$pat/, @array2;
print Dumper(\@array3);

__END__
$VAR1 = [
          'v234_txt',
          'v453_txt'
        ];
