Can a shunt be diagnosed with a liver biopsy?
In animals with shunts, the liver is smaller than normal because it is atrophied from poor blood flow. On a liver biopsy, the tissues appear shrunken. Some of the vessels are very tiny, while others multiply in an attempt to improve the blood supply and drainage. These changes are called hepatic microvascular dysplasia. Hepatic microvascular dysplasia (HMD or MVD) can also occur in dogs without liver shunts; therefore, other tests are needed to be determine if a shunt is also present.
