Trachael Collapse in Three Calves; Surgical Approach and Pathological Observation.

Partial costectomy for tracheal collapse and stenosis associated with perinatal rib fracture in three Japanese Black calves

“…Extra- or intra-luminal stent therapies for tracheal collapse have been well known in canine patients [ 10 ]. In farm animals with the condition, hand-made extra-luminal prosthesis, open-ended coil spring or made from polypropylene syringe, has been also applied for surgical correction [ 3 , 7 , 11 , 13 ]. Calves with the disease caused by rib fractures have also received the surgery [ 4 , 5 , 12 ], but prognosis has been relatively poor [ 4 , 5 , 12 , 17 ].…”
