    A portosystemic shunt is abnormal vasculature connecting the portal vein and the systemic circulation allowing the portal blood to bypass the liver and causing the liver to not develop normally. Shunt patients are often smaller than normal, have vomiting or diarrhea or decreased appetites, neurologic signs like seizures, weakness, disorientation, and may be aggressive or extremely passive, causing owners and veterinarians to be concerned and run blood tests. Liver values may be increased or normal. These blood tests may show a low albumin and blood urea nitrogen (alb and BUN) and glucose (glu) and cholesterol Chol). If these test values are abnormal, with the symptoms described before, a Bile Acids test, resting (fasted) and postprandial (after eating), is often run to confirm a diagnosis. Radiographs can help diagnose a shunt by showing a small liver. An abdominal ultrasound may identify the shunt or it may be identified at surgery. Shunts can be treated surgically or medically or sometimes with a combination of both. Your dog's albumin and BUN were normal. What are his symptoms? If he doesn't have any of the symptoms described above it's very unlikely he has a shunt. Kara, DVM

  • Can Adequan cause bleeding tendencies with my dog

    Can Adequan cause bleeding tendencies, could it be harmful to her spleen mass and/or kidneys? My dog has had three Adequan injections now, over the course of 1 1/2 weeks. She is old and also just started taking a course of Acetaminophen for gum disease. About a year ago, we tried Metacam for her arthritis but it caused problems with her kidney. We also know she has a mass on her spleen about the size of a small grapefruit. As I said, she's had three injections and seems "out of it"; sleepy. One of her rear legs also seems to be "giving out" on her at random moments. Thank you, Cath
