Many years ago we had a funny friend who ran high-end horse auctions for a living. He was the pedigree man (similar to the 'color man' in broadcasting) and was all-business when he was working, but
highly irreverent and funny when he wasn't.
I will never forget the time when we showed up at a sale he was working, looking for a nice Paint mare. We had been standing outside one mare's stall for quite some time when he spotted us, and came running over.
"You don't want that one," he said, shaking his head. "She's got her ROM -- in sales."
I thought about that today and silently chuckled as we watched Pookey Bear standing patiently (and a tad drugged-ly) amongst his friends at La Mesa Equine, getting ready to earn his ROM in x-rays. By my count, it was his tenth visit to the radiology room--no question about it, he now 'knows the drill' and could probably depress the plunger with his teeth!
This time, however, in addition to the usual images, he had some special pictures taken.
After a thorough clip, prep, and tourniquet application, he was injected with some contrast media, and imaged specifically to assess blood flow in his problematic right foot. This procedure, called a venogram, is a useful adjunct to laminitis treatment, as it provides information about the degree of tissue perfusion in the compromised feet that helps greatly with future decision making.
If the blood flow is decent, then subsequent treatment has a reasonable chance for success. If the blood flow is severely compromised, that usually has a negative effect on potential outcomes (click here for more info and images from The Horse:

Fortunately, in Pookey's case, his venograms looked good. The images were crystal clear and very artistic looking--someday, when he is well, I might even ask for copies to enlarge and hang on my wall! But right now I am just thankful for evidence of decent circulation, and the generous amount of sole he is growing on his left front, and on the heel of his right.
Of course not all of Pookey's news was good.
Thanks to continuing pain in his right front, we are now debating the merits of the next logical step in his treatment plan: a tenotomy of the deep digital flexor tendon. Cutting the tendon would relieve the pressure that it exerts on the distal phalanx (P3) which, in Pookey's case, would likely relieve some of his pain. Ideally, the surgery enables the laminae to re-grow by removing some of the force that keeps tearing them apart--at least the downward/rearward force that causes continued rotation.
At least I think that's what it does. Much to my dismay, effective treatment of laminitis draws heavily on physics, a subject which I alternately slept through and sweated through, but never really understood.
Pookey Bear is just glad that Dr. Donnell, Dr. Wilcox, and Joe evidently were wide-awake during physics class, and are happy to share their expertise with him!
