I was at Stone Lion Veterinary hospital this week and Clare Rusbridge told me that Daffy's syrinx has collapsed from 4 mm to less than 1 mm over 6 months, following his ventriculoperitoneal shunt operation in March this year. Daffy has severe hydrocephalus and moderate syringomyelia when first diagnosed in 2009. It was decided that because of his severe dilated ventricles, a shunt would be preferred surgery over decompression. Apart from occasional scratching and a slightly weaker front right paw, (he trots well though,) he has no other symptoms and is on pregabalin.
I am thrilled!
