A 5.5-month-old female domestic longhair cat was examined because of dorsal deviation of the caudal aspect of the sternum and progressively worsening dyspnea during play activities.
A diagnosis of pectus excavatum was made clinically and confirmed radiographically. The cardiac silhouette was shifted into the right hemithorax. The vertebral index (VI) and frontosagittal index (FSI), which are radiographic indices used to grade the extent of the deformity, were 5.2 and 3.0, respectively. Minimum thoracic height was 13 mm at this time.
The sternal malposition was corrected during surgery; for stabilization, an internal splint was provided by use of a plate that was applied to the ventral side of the sternum. Radiographic indices improved until day 85; at that time, an increase in the distance between plate and sternum was detected, and plate removal was advised. The radiographic indices improved again after plate removal. At 310 days after surgery, VI was 9.6, FSI was 1.6, and minimum thoracic height was 34 mm. No dyspnea was evident during physical examination.
Results of treatment suggest that this technique may be useful as an alternative surgical option for cats with pectus excavatum that have a noncompliant sternum.
一只5.5个月大的雌性家养长毛猫因胸骨尾端背侧偏移以及在玩耍活动中呼吸困难逐渐加重而接受检查。
临床诊断为漏斗胸，并经X线摄影证实。心脏轮廓移向右侧胸腔。用于评估畸形程度的X线摄影指标椎体指数（VI）和额矢状指数（FSI）分别为5.2和3.0。此时胸廓最小高度为13毫米。
手术中矫正了胸骨位置异常；为稳定起见，使用一块钢板固定在胸骨腹侧作为内夹板。直到第85天X线摄影指标有所改善；此时，检测到钢板与胸骨之间的距离增加，建议取出钢板。取出钢板后X线摄影指标再次改善。术后310天，VI为9.6，FSI为1.6，胸廓最小高度为34毫米。体格检查时未发现明显呼吸困难。
治疗结果表明该技术可作为漏斗胸且胸骨不顺应的猫的一种替代性手术选择。
