Clinical

In this episode, Anne Chauvet, DVM, DACVIM, CHT-VT, shares insights with our host Adam Christman, DVM, MBA, and listeners from her extensive career treating neurological conditions. 

Chauvet also explores the importance of distinguishing clinical symptoms from radiographic findings in disc disease, especially in prone breeds, the complexities of brain tumors in aging dogs, highlights MRI as a key tool for precise diagnosis, and more throughout the episode. 

: The big thing I tell veterinarian, just remember, when you're thinking about brain tumors, they don't usually happen unless you have a certain age. Now, I'm going to have a caveat in that that the youngest one I've had was 3 1/2 year old with a little Jack Russell, but usually it's 4 years and older. So if you have a 2 1/2 and a half year old little dog that begins seizuring, so therefore has a cortical lesion in the brain, the odds of that being a brain tumor are pretty darn low to none. If you have a 9-year-old pit bull, you have a much greater chance of having a brain tumor over idiopathic epilepsy. So you're going to make your decisions on whether you work up or not, or how far you can push your client for that. So the signs you're going to see are dependent entirely on the anatomy. So if I section out the brain, the front is going to be usually seizures. 

The cortex is very prone to seizure, particularly in what we call the Piriform lobe, which is the part of the brain that on each side of the brain will turn around, curl towards the midbrain that's very prone to seizure, and it's a lovely place for gliomas to launch themselves in all those pit bulls, Bulldogs, they tend to have a lot of gliomas. Boxers famous for it as well. So that's an area that often gets seizures. Then you look at things like midbrain, we see a lot of midbrain problems with pituitary tumors. Those are more of the dog that's very dull, aimless walking is going to kind of start running into things that often people label it for senility. Be careful with that senility label, because if you overlook it. It might be too late for us to be able to help the patient.

Gaemia Tracy, DVM, DACVIM, (Neurology), joins The Vet Blast Podcast to talk about intervertebral disc disease (IVDD) in canine patients. He explains percutaneous laser disc ablation and more. 

Below is a partial transcript. Listen to the full podcast for more.

: Yeah, so the procedure is called percutaneous laser disc ablation (PLDA) and what it is it's a purely preventative prophylactic procedure that's minimally invasive to prevent disc herniations... This procedure is minimally invasive [and] use a spinal needles to approach each disk space in the middle of the back, where  these herniated discs tend to occur. And then, using fluoroscopy, I pass laser fibers through those spinal needles right into the middle of each disk space. And the goal is to deliver a laser impulse into each disk space that takes the degenerative disc that's now dried up and desiccated and breaks it up into much smaller pieces, takes it back towards a liquid state and decreases the pressure at each disk space.

Ane Uriarte, DECVN, MRCVS, DVM, EBVS, RCVS, joined Dr Christman and discussed how the speed of onset of symptoms can affect the urgency with which a pet parent should seek care.

Uriarte said: "For example, you have a 10-year-old dog that has been slowing down for 6 months. He's just limping a little bit, and then, in 2 [or] 3 days, he is unable to walk. You may not need to rush that Friday night to see your neurologist, because it's likely to be something that is slow progressing."

She added that in the inverse is also true. Quicker onset of more severe symptoms should be greater cause for alarm. Uriate explained: "On the other hand, you have a 2-year old, super-bouncey, nice and healthy French bulldog or dachsund, that was running 10 miles with you and that night is unable to get up. That is definitely an emergency."

According to Uriarte, it comes down to a few factors in context. "So it would be a combination of how severe it is—if he's not able to walk and requires further assistance—and how fast it happened," she said.

In this episode of The Vet Blast Podcast, Dr Adam Christman interviews Ane Uriarte, a specialist in veterinary neurology, about the different approaches to spinal injuries. 

Episode 75: Not all spinal injuries require surgery

According to Antonio L. Bowens, DVM, owner of Bowen’s Locum Veterinary Neurology & Neurosurgery Services, when examining a patient for a neurologic condition, it's crucial that you perform a physical exam prior to a specialty exam. 

“Just keep it simple. Neurology is already complicated enough. The first question you need to ask yourself is, 'Is this patient normal, orthopedic, or is it neurologic?'" Once you think the patient has a neurologic problem, the next step is ‘is it brain or spinal cord.’ Then, you take it from there," he tells Adam Christman, DVM, MBA, in this episode of The Vet Blast Podcast. 

Bowens also distinguishes the clinical signs of various neurologic diseases and offers insight into diagnosing these conditions and how to localize the lesion.

“With central vestibular disease, the hallmark clinical signs can either be a vertical nystagmus or conscious proprioception deficits," says Bowens. 

“Those with the peripheral vestibular problem may have a facial palsy, and usually that facial palsy is on the same side as the lesion," he adds.

Episode 58: Neurology simplified

Dachshunds are the human equivalent to dwarfism, says neurologist and neurosurgeon Fred Wininger, VMD, MS, DACVIM (Neurology). “When we artificially bred dachshunds to have short little legs and a long back, we essentially artificially created a condition known as chondrodystrophy, which is Greek for ‘faulty cartilage.’” Where a Labrador retriever may have disk degeneration at age 8, 9, or 10, he explains, dachshunds have complete degeneration of their disks by the time they are 3 years old.

“It’s like they need another pair of legs in the middle of T12 and T13,” Christman joked. “Right,” Wininger agreed, “or more ribs.”

In this episode of the podcast, Dr. Wininger, who practices at Charlotte Animal Referral & Emergency Care in Charlotte, North Carolina, shares his knowledge about IVDD, including the differences between type 1 (degeneration of the inside of this disk predominantly) and type 2 (more of a slow protrusion or disk shifting that causes compression of the spinal cord). “Most dogs are probably somewhere on the spectrum of having a little bit of both,” he says.

Wininger also talks about type 3 herniation, also known as a missile disk or torpedo disk, which is now being seen due to the use of magnetic resonance imaging (MRI). In these dogs, he says, rather than a primary herniation or protrusion, a normal disk that is not that desiccated will rupture through, and actually not only bang the spinal cord but penetrate the spinal cord or hit it and then dissipate away. The new term is acute noncompressive disk herniation. “Those are dogs that get spinal cord injury in the absence of needing surgery.”

Regarding diagnostics, “The gold standard is always going to be an MRI,” Wininger says. “MRI is going to enable you to see not only the disk herniation and the rest of the spinal column, but it’s going to let you see the degree of the spinal cord compression.” Although computed tomography (CT) is not the first option, Wininger says there are some benefits to using this modality. CT is cost-effective, quick, and does not require the patient to be anesthetized like MRIs do.

They also discuss what types of herniation are considered a surgical emergency versus what can be treated with medical management, how the use of advanced imaging techniques has altered the typical treatment course, newer prevention options, and factors affecting patient recovery time.

Episode 16: The latest on disk herniation in dachshunds

After taking a graduate course in neuroscience during his undergraduate studies at Tuskegee University, Antonio Bowens, DVM, was hooked. Well, he was hooked on human neuroscience, anyway, with a plan to go to medical school to become a neurosurgeon. Fortunately for dogs and cats, he was waitlisted at both medical schools he applied to but was accepted to Tuskegee’s College of Veterinary Medicine. Bowens decided to commit to Tuskegee with the plan to go to medical school after veterinary school—until he learned that he could specialize in veterinary neuroscience.

For the past decade, Dr. Bowens has been practicing veterinary neurology and neurosurgery, first in a solo practice and then as a co-owner. When the partnership did not work out, Dr. Bowens decided to become a locum veterinary neurologist and neurosurgeon. He is now owner and head of neurology and neurosurgery at Veterinary Referral & Emergency Hospital in Arlington, Texas.

“Basically, he tells Dr. Christman, “the way things work now I usually provide services on a mobile basis to general practitioners in the area. I also travel out of state to provide services for referral/specialty hospitals that are trying to establish a neurology/neurosurgery service or just filling in for a colleague [who] needs to take some time off.”

Dr. Bowens also shares his clinical experience with disk disease and other neurologic conditions, as well as advanced and alternative therapies.
