As owners, your concern for the possible presence, severity, duration and
management of Syringomyelia by itself or associated with Chiari - Like Malformation will likely give rise to questions that we have endeavored to anticipate and answer in a helpful and instructive manner in the appropriate areas on this site.
It is similar to the human condition Chiari malformation (some vets refer to it as Arnold Chiari syndrome which can be confusing as the original description by Arnold was
of syringomyelia associated with spina bifida and this is not the case in the CKCS).
The Report was followed up in April 2008 by a Workshop meeting at the House of Lords to look at how the
problem of Syringomyelia was being tackled and what more could be done.
The most common
symptoms of Syringomyelia are hypersensitivity in the neck area resulting in an uncontrolled urge to scratch at the neck and shoulders giving the appearance of air scratching while walking.
The earliest known case with history and radiographs
suggestive of syringomyelia, was presented to the Royal Veterinary College, UK in 1987.
The first
reports of syringomyelia in Cavalier King Charles Spaniels (CKCS) appeared in 1997 almost simultaneously from the UK, South Africa and Australia.
Many scientific papers looking at groups of 16 or more asymptomatic CKCSs have found a high
incidence of syringomyelia ranging from 26.5 % (Cerda - Gonzalez et al 2009 in 49 dogs), 47 % (Marino et al 2009 in 91 dogs) to 65.4 % (Rusbridge et al 2007 in 55 dogs).
The
resolution of syringomyelia has been only recently reported in veterinary patients, and based on a large scale study, can take many months or even years to completely resolve.
As head of the Department of Surgery, he has pioneered micro-hip replacement surgery in pets, the diagnosis and treatment of elbow dysplasia, and corrective
surgery of Syringomyelia / Chiari like malformation in dogs.
By far the most important sign
of syringomyelia is pain.
The other medicatios can be used to depress the clinical signs
of syringomyelia are; acetozalamide, furosemide, corticosteroids, and phenobarbital.
A newly - recognized and perplexing problem for cavalier breeders around the world is that
of syringomyelia (SM), sometimes called syringohydromyelia, or caudal occipital malformation syndrome (COMS).
