🚨 What are we looking at on this ultrasound?
This ultrasound image was taken today from a horse presented for colic.
Ultrasounding horses with colic can provide incredibly valuable information.
➡️ In this image, we identified a large blood vessel running lateral to the right dorsal colon. This is not a normal finding and raised our suspicion that the large colon had rotated.
Whilst the horse in question had a normal heart rate and was only mildly painful, the ultrasound confirmed that surgery was indicated.
The horse was then taken to surgery, where a 360° large colon volvulus was confirmed. If left for too long (even just a few hours) a volvulus can result in the blood supply being cut off and the intestine being severely and sometimes irreparably damaged. Thankfully we got in quickly in this case and the large colon was still healthy so fingers crossed for a good recovery.
While ultrasound cannot diagnose every type of colic, certain findings can significantly increase our suspicion of surgical disease and help us make faster decisions.
⏰ Time is one of the most important factors in severe colic cases. The sooner a horse requiring surgery is identified and referred, the better the chance of a successful outcome.
If your horse develops signs of colic, don’t wait to “see if it settles.” Early veterinary assessment can make all the difference.
