Pastern Leukocytoclastic Vasculitis treatment with oral medication - 1 week later

Below is a link to a vet article on Equine Pastern Dermatitis. It includes information about Pastern Leukocytoclastic Vasculitis. My vet supplied me with print outs of these pages. It's interesting to compare some of Archie's recent photos with the image on page 4 (218) in this article.

Here are some photos taken one week after I started Archie on Trental 400 tablets. This area is not sore to touch at all. The inflammation has gone and the hair is growing back. I am covering the area with just the mesh leg wraps now.

And here is a photo of Archie's bottom. I had been applying Potties White Ointment to the area for 4 days. The morning this photo was taken these scabs just wiped off.

Last week the elastic on one of Archie's leg wraps ripped and I had to think of a way to cover his hocks while I repaired the wrap. So I put a nappies on both legs and duct taped them to his rug leg straps (if I had only put one nappy on his rug would have slipped over to one side). When I visited two days later the nappies had not moved.

Nappies used as hock bandages
