The operation posed a significant challenge due to the large mammal’s unique anatomy making anaesthesia unpredictable, the zoo said.
Lying down for extended periods of time can also compromise the animal’s blood circulation and cause life-threatening complications.
To minimise risk during the surgery, the veterinary team prepared a deep hay bed and supported Sahara’s neck with a wooden board.
They also used blindfolds and earplugs to reduce stress, while keepers massaged her neck throughout the procedure to maintain circulation.
The specialist team included vets, an equine surgeon and an anaesthetist.
