According to the article, high BATS and liver enzymes can be expected following liver shunt surgery. The important thing is to maintain close contact with your vet and follow their instructions to the letter. Here is a quote from the article:
Quote:
Animals that undergo PSS ligation require supportive therapy and close monitoring for signs of portal hypertension (hypovolemic shock, progressive hypothermia, severe abdominal pain); if these signs occur, the animal should be taken back to surgery for ligature removal. A second partial ligation can be performed after the animal has recovered completely from the surgeries and portal hypertension. Mild portal hypertension may be seen in some animals 2-4 weeks after surgery and is usually evidenced by abdominal distension from fluid accumulation.No treatment is required unless the animal is having trouble breathing; in that case, the animal is treated with diuretics (e. g. furosemide) and, if albumin is low, hetastarch. Lactulose is continued for a minimum of 2-4 weeks, based on clinical signs and severity of the disease. Yogurt with active cultures or probiotics (live bacterial cultures) may be as beneficial as lactulose in some dogs. Protein restricted diets are fed until the animal shows signs of improved hepatic function (i.e. normal albumin or normal scintigraphy).
Serum bile acids often continue to be abnormal after shunt ligation; in one study, 75% of dogs had abnormal values a median time of 18.6 months after ligation. If bile acids are abnormal at 3 months, protein restricted diet is continued and the animal is started Marin or Denamarin (milk thistle or silymarin). If blood work is still abnormal 6 months after the surgery, the dog should be rechecked for shunting (portogram, scintigraphy, ultrasound) and undergo a liver biopsy to determine if the problem is caused by incomplete closure of the original constricting device, presence of a second congenital shunt or multiple acquired shunts, or hepatic microvascular dysplasia or another liver disease. |
