RNA from tiny amounts of tissue?

I find myself in the position of having to make RNA from tiny amounts of 
mouse vascular tissue for some RT-PCR.  Normally, for rat vessles, we 
pulverize the frozen tissue, and follow with homogenization in TriZol 
(they cannot be homogenized directly -- they are too tough).  However, I 
am concerned about these sub-milligram mouse tissues (anterior cerebral 
arteries and tail arteries).  Does anyone have any idea how far the 
TriZol type preps can be scaled down?  Or does anyone have any other 
good ideas for working with very small amounts of tissue?

Thanks in advance,
