Four months after losing Bonnie in 2003, I started to look for another Cavalier puppy.
I contacted many breeders all over the country and told them about my experience with Syringomyelia. I wanted to be as sure as I possibly could that my next Cavalier would be healthy. and at that stage I hadn't understood how widespread Syringomyelia was in the breed.
In the end I took a chance with Rosie, a beautiful ruby girl who became available at the age of ten months.
It was not long before I began to worry. Why was she scratching her ears and rubbing her face back and forth along the carpet? I heaved a sigh of relief when my vet found an ear infection which was easily treated. But the face rubbing continued and my anxiety kicked in again. I was aware that I had an irrational fear of Syringomyelia but I had to know if Rosie, too, had inherited this disease.
My vet agreed to an MRI scan and this was done when Rosie was fourteen months old. The results showed that Rosie did have the chiari-like malformation at the back of her skull. Her hindbrain (cerebellum) was compressed and her brainstem slightly kinked. There was a small herniation of her brain into the spinal area, but no syringomyelia. This was both good and bad ws: no syrinx, but there was the skull malformation which could cause it to develop in the future and this is indeed what happened.
A second MRI scan a year later, carried out by Dr Clare Rusbridge at the Stone Lion Veterinary Centre, Wimbledon, London, UK, showed that a small syrinx had formed in the upper (cervical) spinal cord. We re-scanned a year later and could see that the diameter of the syrinx had widened.
As you can imagine, during all this period I was consumed with worry. By this time I had learned a great deal more about Syringomyelia and I knew what lay ahead. I didn't know how I would cope emotionally with another SM dog. What kept me going was the thought that Rosie was the innocent victim who had inherited this awful disease. I loved her as I had loved Bonnie and it was my responsibility to take care of her and give her the best quality of life I could.
I discussed the treatment options with Dr Rusbridge: to treat medically for pain relief or surgically by foramen magnum decompression. It was an agonising choice, but in the end I opted for the surgery in the hope that the progression of the disease could be halted or slowed down.
Decompression is major, invasive, pioneering and expensive surgery. Recovery can take many weeks or even months. It involves cutting a piece of bone from the back of the skull and top of the spinal column. The outer covering of the brain is also incised in order to remove adhesions which have formed on the surface of the brain. A patch is then placed over the incision site.
