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

[摘要] References(17)2.3-month-old (Case 1), one-month-old (Case 2) and 6-month-old (Case 3), Japanese Blackcalves presented with mild to severe wheezing. All calves had histories of dystocia atbirth with breech presentation. Physical examination, thoracic radiography, endoscopy orcomputed tomography indicated wheezing associated with tracheal collapse and stenosiscaused by perinatal rib fractures. Partial resection of the fractured first and secondribs was performed on all calves. The respiration in Cases 1 and 2 immediately improvedafter the surgery, while Case 3 required two weeks to improve. Cases 1 and 3 grew uphealthy and were sold at auction, but Case 2 had a recurrence of wheezing at three monthspost-discharge and showed growth retarding. Partial costectomy may be an effectivesolution for control of respiration, however, further cases are required to discuss thecriteria for surgical management and to obtain favorable postoperative prognosis in calveswith tracheal collapse and stenosis caused by perinatal rib fractures.
