Inadvertent Autotransplantation

I believe that if one is removing a damaged, non-neoplastic spleen it is considered acceptable (and possibly advisable) to implant fragments into the omentum.

Certainly many of us will have seen cases where something nasty has ruptured and seeded throughout the abdomen (at least I've always assumed that it was a rupture; I guess it could just be micrometastasis)

I will try and auto transplant parathyroid tissue if I can identify it but was unable to leave it in while doing the thyroidectomy. I am not sure if it works but I feel at least i am trying. we generally do thyroidectomies as two stage ops and I have to admit I have not followed up to try and see what happens. I might try and keep a note in future. Of course if the parathyroid is saved when the other side is done we will never know if it helped!

I have a case at my practice that has just come back confirming presence of ovarian tissue about 8months after OVH.

Our plan is to do an xlap when she is showing signs of heat again. I guess the surgery was not done properly the first time, there is ectopic ovarian tissue or autotransplantation? I will let you know what happens.

I have attempted parathyroid autotransplation in the past. I don't know if it worked if it was during a planned bilateral thyroidectomy I would stop at that stage and close up. Then do the other side 4-6weeks later. I'm not that confident of it?

Cheers,

Stuart.

I guess if we accept that poor technique in lumpectomies can drive neoplastic cells deeper into tissue, then specks of ovary might go the same way. It would have to be a pretty small bit of tissue (a millimetre or less?) at the time of reattachment, for the lack of blood supply to not be a factor. Then there's certainly a lot of potential in those cells for differentiation.

When I was in large animal practice and doing cat spays midline under rompun and ketamine (it was a while ago), we'd get the odd one which would start to come calling again, often months later. I always assumed that I'd left a remnant, but generally the farmers were happy providing they didn't get pregnant. a little different from your situation, though.
