Blood is still shunted from being cleansed by the liver and ammonia is still building up in the blood and still can cause symptoms but since there is no single shunt to close off surgically, it can only be managed medically not surgically.
I agree that the ultrasound reader is of paramount importance and I would make sure the ultrasound is done by a board certified radiologist who is working in tandem with internal medicine. |
Thanks for pointing out my typo... I have a headache today.... but from U of T website:
"Single congenital portosystemic shunts must be differentiated from multiple acquired shunts secondary to portal hypertension, and from hepatic microvascular dysplasia. Hepatic microvascular dysplasia (HMD) signifies a disorganization of the liver's microscopic architecture which is similar to that of dogs with single congenital shunts. HMD has been reported in small breed dogs such as the Yorkshire terrier, Cairn terrier, Maltese, cocker spaniel, and poodle. Dogs with HMD display biochemical, hematologic, and clinical changes consistent with portosystemic shunting but
lack a macroscopic portosystemic shunt. Definitive diagnosis is by ruling out a macroscopic shunt through exploratory laparotomy, nuclear scan, or portography. Signs of HMD are managed by low protein diet; lactulose is added if necessary
."
Note: HMD = MVD
So I guess it depends on who one reads... and , yes, I said the symptoms are the same....
