New Ultrasound Test For
Congenital Portosystemic Shunts
PARTICIPATION NEEDED
For healthy Yorkies that are 6-12 months of age in and around the Madison, WI area
Dr. Robert T. O'Brien and colleagues at the University of Wisconsin School of Veterinary Medicine are
evaluating a new ultrasound test for congenital portosystemic shunts. These veterinarians hope that
the new test will be able to replace radioactive scintigraphy and the more invasive portogram
("blood vessel dye study"). Dr. O'Brien, a board certified radiologist, is particularly interested
in evaluating healthy Yorkies that are 6-12 months of age to serve as a control population ("normals").
The test will require placement of an intravenous catheter and a 15-25 minute ultrasound.
There is no risk to the procedure and the dogs are able to go home immediately after the test. The
investigators will pay for the ultrasound and bile acids (if these are needed); there should be no
cost to participants for the test.
If you are interested in becoming involved with this study, please
contact Dr. O'Brien at obrienr@svm.vetmed.wisc.edu
Please pass this information along to other Yorkie
breeders and owners in and around the Madison, WI area that might be able to help.
