Patent ductus arteriosus (PDA) is a heart defect that occurs when the ductus arteriosus (an opening between the aorta and the pulmonary artery) fails to close at birth. A PDA is usually diagnosed when your veterinarian hears a continuous heart murmur during a routine physical examination of your puppy. This article explains PDA and discusses signs, treatment, and prognosis for this condition.

Pericardial effusion refers to the abnormal accumulation of fluid in the sac surrounding the heart. Pericardial effusion can have a number of underlying causes, including inflammation, infection, cancer, and hereditary defects. Mild cases of pericardial effusion may be asymptomatic, but more significant fluid accumulations can interfere with the heart’s function and lead to severe effects such as sudden death. Treatment and prognosis is dependent upon the underlying cause of the condition.

Our culture is experiencing an ongoing evolution of the human-animal bond: the family-pet relationship. We live in increasingly intimate contact with the animals who share our lives, and veterinary care has progressed to a level that supports longer life expectancy in pets than ever before. Pets are now living longer and better because we are able to feed them better and protect them from infectious diseases and parasites. This means we are witnessing a surge in the segment of the pet population that is senior and geriatric. In fact, it is not so rare to see cats 20 years of age and older.

Pituitary macroadenomas are large tumors of the pituitary gland that are either functional (secrete hormones) or non-functional (do not secrete hormones). The clinical signs depend on the type of macroadenoma, though become severe over time in either case. Diagnosis requires specialized CT or MRI imaging. This handout explains the effects of macroadenomas in cats and the treatment options available.

Pleural effusion refers to the abnormal accumulation of fluid within the chest cavity. The fluid is not found within the lungs, but instead within the pleural sac, essentially meaning the lungs are floating in a chest that is full of fluid. Several conditions can cause pleural effusion, including chylothorax, heart failure, and tumors in the lungs or chest wall. Immediate treatment often requires oxygen support and the removal of the excess fluid by thoracocentesis, which can also then be tested to diagnose the cause of the pleural effusion. Treatment and prognosis vary depending on the underlying cause of the pleural effusion.

Pneumothorax is an accumulation of air outside the lungs, but inside the chest wall. The air outside the lung prevents the lungs from inflating normally, and can lead to lung collapse. There are several variations of pneumothorax.

Polycystic Kidney Disease (PKD) is an inherited condition that causes multiple cysts (fluid pockets) in the kidneys. Persian cats and breeds with Persian bloodlines are most commonly affected. The clinical signs, diagnosis, genetic testing, and treatment options are explained in this handout.

Polycythemia vera, or “true” polycythemia, is a rare disease of cats in which too many red blood cells (RBCs) are produced by the bone marrow. This is the opposite of anemia, in which there are too few red blood cells.

This handout explains post-vaccination sarcomas (also called injection-site sarcomas) in cats. They are a rare consequence of vaccine injections (and other drugs or materials) that can cause a very aggressive form of cancer at the site of the injection. The incidence of this condition, as well as precautions you and your veterinarian can take, are highlighted.

Telemedicine is the act of practicing medicine from a distance and your appointment will be conducted by a licensed veterinarian. Before your appointment, gather information on your pet’s history and your current concern. Look at a calendar and write down a timeline of your pet’s problems. Be prepared to answer questions that you would normally be asked at an in-person appointment. Write notes to help you remember everything. Most telemedicine appointments involve the use of some type of video chat. Conduct your visit in a quiet area with good lighting and have your pet with you before the call starts. Not all concerns can be addressed through telemedicine. If your veterinarian is unable to arrive at a diagnosis via telemedicine, he or she can help you determine the next step for your pet to ensure that he or she receives optimal care.
