Have read 4 of Lisa's links and am shaking like a leaf. Have looked up endless illustrations to try to get a visual, too, of each of these formations, etc. Can't really find a good illustration of a cross-section of the liver with polysystemic shunts yet though. Going to rest my eyes and hold my Tibbe.
