Today I saw a puppy with a short circuit in the portal vein. She was thin, drooled and had poor appetite and was sent to see the doctor. The pet owner initially thought it was a gastrointestinal problem, but unexpectedly there was a liver problem. The name of this disease is portal short circuit. So what exactly is portal short circuit?
Today, people will talk about [what happens when dog portal vein short circuit]. The theme includes:
1. What is portal vein short circuit?
The hepatic portal vein short circuit is an abnormality between the portal vein circulatory system and the systemic circulation. Pathological characteristics: The liver becomes significantly smaller and has dark spots. With arterial vascular growth and small or missing portal veins, there is typical liver contraction. Other features include sinusoidal gland blockage, common bile duct growth, human fat granuloma, increased periphery of the portal vein and vacuolization around the portal vein.
This disease generally has congenital vascular malformations and non-hereditary vascular short circuits: 1. Congenital vascular malformations
Congenital portal short circuit is a common abnormal disease in dogs. Cats are a little rarer, but with the improvement of the diagnosis level, the confirmed cat cases in recent years have also gradually increased. This disease is highly prevalent in Spanish wolfhounds, dachshunds, Yorkshire beagles, Maltese, small and medium-sized German and Canadian dogs. Moreover, most of them are single-vessel short circuits. Intrahepatic short circuits are common in large dogs, and patent venous catheters are a common type of intrahepatic vascular short circuits. Small and medium-sized dogs and cats have common extrahepatic vascular short circuits. The keys are:
Portal vein singularization
Portal vein abdominal artery short circuit
The left gastric artery short circuit and abdominal artery short circuit. This type of extrahepatic vascular short circuit is common. Portal vein locking is common. This type of extrahepatic vascular short circuit is often several short circuits
Acquired portal vein short circuit
Acquired portal vein short circuit, and there are two key reasons:
Enlarged blood friction resistance of portal vein system software will cause the occurrence of cost diseases, which is a chronic diffuse fibrosis process secondary to the liver. Cats rarely develop this disease.
Chronic hepatitis B in puppies
2. Do the small pet have these symptoms if it suffers from a portal short circuit?
Typical symptoms of sick pet dogs, the symptoms often appear before one year old. The key symptoms include:
Twitching, mental silence, especially after meals, small body shape, slow growth and development, significantly lower than dogs and cats of the same age. They often drool, which is particularly obvious in cats. Puppies will also experience too heavy urine smell. Gastrointestinal symptoms. I often hear the owner complaining about intermittent diarrhea when seeking medical treatment. III. After the dog has a portal short circuit, what will happen to the basic test?
Routine blood test: mild anemia, mostly small-cell anemia
Biochemistry: Liver index values are slightly increased, urea nitrogen and albumin are low
Urine test: Microscopic examination will see urate crystals
Elevated blood ammonia and bile acids (about 80% of short-circuit cases will appear)
X-ray: There will be a decrease in liver volume
Abdominal ultrasound: There will be an enlarged kidney function volume and a lot of bladder light to the crystallization urine
4. How to treat the portal short circuit of the dog?
Because the liver is different from other human organs, the portal vein bears 80% of the blood supply, and the short-circuit condition indicates a decrease in blood supply in the liver, delayed language development, and serious damage to the effect. So how should we treat the short circuit of the portal vein of the Dog?
Surgical treatment: After the short-circuit of the external hepatic portal vein is identified, the closure ring ligation surgery or chemical fiber paper can be placed according to the surgical treatment.
Drug treatment method: improve ingredients, reduce protein components in the ingredients, choose high-quality and easy-to-digest protein, and have productized liver prescriptions and grains. Lactulose: Oral administration of lactulose can improve the pH of the intestines and reduce the digestion and absorption of ammonia and other endotoxins. Antibiotics: beneficial bacteria that reduce ammonia production in the gastrointestinal intestines, avoid excessive breeding of beneficial bacteria, and reduce the cause of ammonia.
The puppy can only live once, and the general symptoms must be cautious!
Many cat slaves usually neglect due to some common symptoms of dogs, which feels not a big deal, but the objective facts are not like this. Taking a puppy for a healthy physical examination on time is one of the necessary standards for the owner. Except for the initial discovery of all physical discomforts in pet dogs, many diseases cannot be seen by human eyes in the early stages. If you discover them early, you can treat them as soon as possible, so that the dog can wait for themselves healthily and happily for a longer period of time. It can also make cat slaves more comfortable. After all, the physical and mental health of pet dogs is the most important thing for dog owners.
