The cardiopulmonary development of 
and
Puppies may be affected by various diseases. The persistence of arterial catheter is one of them.
canine arterial catheter persistence corresponds to cardiac malformation, which hinders the good blood circulation of canine lung. Of the 10 dogs with heart disease, 6 died before the age of 18 months, if not found and treated.
is a congenital heart malformation.
ductus arteriosus persistence (PCA) is one of the most common congenital heart malformations in dogs. What is this?
arterial catheter is a small blood vessel that allows the fetal heart and then the neonatal heart to deliver blood to the lungs. In a healthy puppy, the arterial catheter automatically closes a few days after birth and the heart begins to irrigate the lungs through its right side. When the vessel is not closed, the arterial catheter is called a persistent catheter. The reason why the vessel is not closed is that the proportion of muscles on the catheter wall is low, so it cannot be completely closed.
This deformity can block oxygen from entering the lungs (blood delivery) and fatigue the heart.
and
statistics show that female dogs are three times more affected than males. In addition, some breeds are susceptible, including poodle, King Charles rider, German shepherd, Yorkshire Terrier or Pyrenees shepherd. The persistence of
PCA symptom
arterial catheter must be detected as soon as possible, Because delaying treatment increases the risk of animal death. In fact, it is estimated that 60% of dogs die 18 months ago without treatment.
due to this additional channel, left ventricular pressure increases. Therefore, the heart must work harder to supply blood to the lungs. However, the early symptoms are not obvious. In fact, fatigue and growth retardation, which are usually associated with it, may be used by masters for the performance of other diseases. There are other symptoms that can make you tinnitus, such as dyspnea, cough and even syncope.
diagnosis of persistent ductus arteriosus in dogs
only veterinarians can confirm the persistence of ductus arteriosus in dogs, Therefore, it is important to check the puppies as soon as possible.
when checking the puppies, the veterinarian can sense the breath that may cause ACP with a stethoscope. In order to ensure this, echocardiography, such as ECG or chest X-ray, is usually performed. If
surgery is confirmed, the only solution
is surgery, because the use of drugs can only be palliative. The operation included double arterial catheter ligation. Although this operation is quite common now, it is still difficult because it requires a lung lobe to reach the heart.
and
can only be performed on puppies. On the contrary, for the elderly, they will seek to take action on the consequences of deformity and improve their life expectancy by prescribing symptomatic drugs because surgery is too dangerous for them
