Causes of diaphragmatic hernia in cats

Can diaphragmatic hernia occur in cats?

Yes. The most common cause of diaphragmatic hernia is an obstruction in the abdominal portion of the stomach. Cats with esophageal obstructions or other esophageal malformations, abdominal tumors, and trauma to the esophagus are at risk for developing a diaphragmatic hernia. Some breeds have a higher risk, for example, Pekingese and Mne Coon cats.

What are the symptoms of diaphragmatic hernia in cats?

Your cat may appear lethargic, may not eat, or may have difficulty breathing, if he has a diaphragmatic hernia. As hernia enlarges and becomes more significant, it may impr your cat’s ability to swallow.

How is diaphragmatic hernia diagnosed in cats?

Diagnosis of diaphragmatic hernia in cats can be done by a CT scan or ultrasound. If a hernia has developed in an adult cat, it may be identified on a radiographic exam as an r-filled sac on the cranial aspect of the diaphragm. In a cat with an esophageal hernia, r can be seen in the stomach or intestine, but is usually only visible in the stomach.

Can diaphragmatic hernia occur in older cats?

Yes. The risk for diaphragmatic hernia increases with age in cats. However, cats with congenital hernias are more likely to have them when they are young.

What are the treatment options for diaphragmatic hernia in cats?

A hernia that occurs in an adult cat can be repred surgically. If a young cat has an esophageal hernia and severe clinical signs, surgical repr should be performed as soon as possible. If a large diaphragmatic hernia has developed, it may be repred surgically. However, if a large hernia is left untreated, it can result in severe respiratory problems in the cat.

What is an azygos continuation?

An azygos continuation is a variation in which the azygos vein (which carries blood from the lower body and abdominal organs to the heart) bypasses the diaphragm and carries blood directly to the heart. This variation is believed to have a genetic basis, with dogs being more likely to have an azygos continuation than cats. It is also much more likely to occur when the dog is a large breed. The azygos vein is very similar to the inferior vena cava, but the diameter is much smaller. An azygos continuation is a congenital defect in which the azygos vein runs between the diaphragm and the esophagus.

An azygos continuation is a form of congenital cardiac abnormality. The defect results in blood being shunted from the lower body to the heart, bypassing the diaphragm. The cat will suffer from respiratory difficulties and heart flure.

This is not a fatal disorder and, if detected early, the cat can be treated successfully by surgery.

What is a caudal vena cava?

A caudal vena cava is a congenital blood vessel disorder in which the vena cava is completely or partially absent. A caudal vena cava is extremely rare in cats. In fact, the only case in which a cat has been diagnosed with a caudal vena cava has been a large domestic shorthr cat that was examined and treated at the Center for Veterinary Clinical Sciences at Texas A&,M University. This is another condition that may be associated with the caudal fossa (lateral abdominal wall at the base of the rib cage in the lumbar region).

What is a “chocolate ear”?

The term “chocolate ear” refers to a rare condition in which a feline’s ear canal is completely filled with chocolate. This chocolate “ear” develops when chocolate (or a related substance) dries in the ear canal. It does not come out of the ear on its own, nor is it harmful to the cat. If chocolate is not removed and it continues to harden in the ear canal, it can cause severe ear damage. There is no known cause of this condition. It appears to be more common in young cats and may occur once in a lifetime. However, most cats with chocolate ears seem to be happy and healthy and there is no reason for a veterinarian to suggest that they be subjected to surgery to “clean” their ears.
