Scarlett's x-ray

Scarlett’s x-ray shows her stuck egg

As her name suggests, Scarlett is a pet that is red, but not a red setter, a redbone coonhound or a red Abyssinian, she’s an African grey parrot with a red tail. This 25-year-old parrot is also an artist, creating colorful abstract works of art in the bathtub. She was referred to The Animal Medical Center to see Avian and Exotic specialist Dr. Kathy Quesenberry for an egg that wasn’t being laid, an avian condition known as egg binding, putting a damper on her artistic endeavors.

Like many medical problems, egg binding occurs in overweight birds with a sedentary lifestyle or a diet lacking adequate calcium. Medical treatments can be effective in resolving a stuck egg – calcium, fluids, lubrication and keeping the bird warm may cause the egg to pass, if not, then manual or surgical removal of the egg may be necessary. These treatments had been tried in Scarlett, but they were unsuccessful.

IDing an Egg
One of the first steps in treating an egg-bound bird is to pinpoint the egg’s location within the reproductive tract. Because eggshells contain calcium, they can easily be seen using a standard x-ray. In the x-ray image on the right, you can see a thin, egg-shaped structure in Scarlett’s abdomen between her pelvic bones representing Scarlett’s stuck egg.

Avian Endoscopy
The inside of a bird’s vent, called the cloaca, contains multiple openings – one for the intestinal tract, one for the reproductive tract, and two small openings for the urinary tract. Dr. Quesenberry used endoscopy to view inside the vent and was planning to remove the egg at the same time. Endoscopy identified a tear at the end of the oviduct where it entered the cloaca, making surgery urgently necessary.

Bird Spay
During the two and a half hour endoscopy and surgery, Scarlett’s torn oviduct at the cloaca was repaired, and the remainder of her oviduct was removed to prevent another egg binding episode. Unlike mammals, most birds have only a single left oviduct and ovary. Because a bird’s ovary is close to large blood vessels, it cannot be removed safely. A “bird spay,” or salpingectomy, is the procedure of removing most of the oviduct so that an actual shelled egg cannot be formed, even though the ovary still functions normally. Scarlett recovered uneventfully. Two weeks after surgery her sutures were removed and she was given a clean bill of health and she has returned to emulating Jackson Pollack-esque abstract impressionism in her bathtub. The photo seen here shows Scarlett as a component of her own artwork.

Help From an AMC Community Fund
The happy ending to Scarlett’s story would not have been possible without the generosity of those who support The AMC’s Community Funds. Scarlett’s care was covered by the Seniors’ Animal Veterinary Effort (SAVE), which provides free or subsidized general and emergency veterinary services for the pets of the indigent elderly.

Ruptured Air Sac: A Unique Bird Disease

March 28, 2012

Raquel the macaw

In 1984, The Animal Medical Center established one of the first Avian and Exotic Pet Services in a veterinary specialty hospital. At that time, the patients seen by the Avian and Exotic animal veterinarians reflected the most popular exotic pets such as ferrets, iguanas, and exotic cats. Over the years the popularity of various pets has waxed and waned, including the rise and fall of the hedgehog, sugar glider, prairie dog, and an occasional frog.

But the presence of birds in our waiting room has been a constant.

Raquel is a talkative blue and gold macaw that is at least 27 years old. She came to see Dr. Katherine Quesenberry for a dime-sized swelling in her axillary area (equivalent to our armpit) between the base of her wing and flank. Dr. Quesenberry suspected a ruptured air sac and scheduled a CT scan to investigate further.

Evolution made birds lightweight for flying. To lighten their bones, some bones contain air (pneumatic bones) as part of their respiratory system. Like reptiles and mammals, birds also have lungs, but bird lungs function differently than ours. With each breath, our lungs fill and empty with air due to movement of the diaphragm. Birds lack a diaphragm, and air moves through the lungs and into and out of the air sacs in two cycles as their sternum expands and contracts with each breath. While air is in the lungs, exchange of oxygen and carbon dioxide occurs. The air sacs help keep birds “light as a feather” and buoyant for flight.

Even though The AMC’s 64-slice CT scan is lightning fast, general anesthesia is required for the procedure. The bird’s unusual respiratory system makes anesthesia a greater challenge than in dog and cat patients. While birds are under anesthesia, we assist their breathing to prevent a build up of anesthetic gases in their air sacs. The advantage that birds have over mammals is that because their respiratory cycle is so fast, they wake up from anesthesia rapidly once the anesthetic gas is discontinued.

On the right you see a reconstructed image of Raquel from her CT scan. Although you can’t see it, her head is at the top, legs at the bottom. The image clearly shows the abnormal air sac exactly as the examination described it, under the right wing. The image is reversed and the right side is shown on the left.

The cause of ruptured air sacs is unknown; even so, they can be successfully treated. A small stent was sutured into Raquel’s ruptured air sac to remove the accumulated air. A follow-up visit showed resolution of the swelling. Raquel is now doing well and hopefully will stay in good health for at least another 27 years!
