Hello animal lovers! I am seeking advice about a shoulder hematoma/seroma in an adult dog, resulting after microchipping.
I recently adopted a wonderful shelter dog. The problem started when she had to be microchipped, she was uncooperative and the technician had to do 2 insertion attempts, over the left shoulder. She bled from the injection sites for a few hours, but seemed ok otherwise.
Two days later, she jumped down out of our tall cargo van, started limping within minutes, wincing in pain, and had obvious swelling on the shoulder where the microchip was placed.
We took her to the vet, where they sedated her and placed a drain for a hematoma. The vet said there was a lot of inflammation, blood and clots. She prescribed an anti-inflammatory, no antibiotics. There was a lot of drainage the first few days, then less and less. The microchip came out, I found it on her bed one morning.
They removed the drain on day 8 with almost no fluid drainage present.
Within 36 hours of drain removal, the drain holes are well scabbed over and I can see and feel a small pocket of fluid (feels like a tiny waterbed) where the hematoma was. It is not growing, even with short walks and normal backyard activity. Her behavior is totally normal, no signs of pain or infection.
After researching, this seems to fit the bill for a seroma. I would prefer to watch and wait as long as she is acting normally instead of return to the vet for diagnosis and more possible interventions…
My questions are:
Does this sound like a seroma?
Could the hematoma have returned?
Should I go to the vet to have fluid drawn to confirm? Does it sound appropriate for me to decline another drain or aspiration as long as she is behaving normally?
Is attempting to place another microchip advisable?
Is it reasonable to assume that these are complications from a poorly done microchipping?
Any insights appreciated, thank you very much!
