This ultrasound shows an obstructive thrombophlebitis of the jugular vein, where inflammation and thrombus (blood clot) formation result in partial or complete obstruction of blood flow.

Common causes include repeated intravenous injections, indwelling catheter placement, perivascular injection of irritant substances, or local infection.

Early diagnosis with ultrasonography is essential to guide treatment, which may include anti-inflammatory medication, antimicrobials where indicated, anticoagulant therapy in selected cases, and careful monitoring of clot resolution to preserve venous function and minimise complications.

Scroll to the second pic for an explanation of what you are looking at!



I mean that’s pretty self explanatory, the vein (in pink) is blocked as there is no lumen so no blood flow!

Carotid artery (in green) is normal. All is surrounded by neck muscles.

As result this horse can’t be injected anymore on the left side but only on the right jugular vein, which you really want to keep open or the horse is in big trouble!

🦴🦴Did you know fractured ribs in foals are often silent emergencies?🦴🦴

- Cause: These injuries typically happen during a difficult birth (dystocia) as the foal passes through the birth canal. They can also occur if a mare accidentally steps on her newborn

- Diagnosis: carefully feel for any crunching or swelling during a newborn exam, an equine thoracic ultrasound is the gold standard, as shown on the picture here. It allows vets to instantly see the break and check for dangerous internal bleeding or punctured lungs

- Treatment: Simple, non-displaced fractures usually just require box rest and pain management for 3 to 4 weeks. Severely displaced fractures require urgent surgical stabilisation using specialized plates, screws, or believe it or not simple nylon cable ties! If left untreated they can then cause lethal punctures to the heart or lungs.

- Outcome: The prognosis is excellent for simple breaks, and foals that undergo advanced surgical repair have a high survival rate and go on to live completely normal, athletic lives.

Another complex injury, in this case of a stifle in a 3yo thoroughbred, which wasn’t far off sound but positive to flex and weak looking in his hind quarters.

Can you find all the lesions here? They are highlighted in the second picture.



Here they are.
In my experience, they tend to do ok after a medial collateral ligament + caudal cruciate injury however here there is an odd intermediate tibial eminence fragment which might complicate outcome. Time will tell but let’s think positive!

A complex fracture of a navicular bone of a racehorse which sadly had a hopeless prognosis.

These injuries are very uncommon and unfortunately there is no treatment

Scroll to 2nd picture to see location of all fracture lines.

💉 💊 🌡️ Fun times… keep your eyes peeled for snotty horses with a cough, especially if recently introduced to the yard and even more so if from Ireland. If any of these symptoms arise and/or temp gets above 38.5c give us a shout 💉 💊 🌡️

- ignoring medical advice
- waiting until the last minute to bring the horse-dog-cat to the vets
- aggressive and rude clients

What a lovely trip to where it all started 20 years ago, allegedly over for an ISELP conference but really just an excuse to visit these two legends!

Can you believe these two heroes trained me when I started and are responsible, or guilty, of the vet I am today?! All that I learnt stems from my internship year in Hagyard’s many many years ago. Even got a chance to say hello to Fiona Robertson!

Hopefully we don’t have to wait another 20 years before we cross paths again!

Well done everyone 🍾🎉🏇
