Abstract

心大血管奇形のウシ451例中5例(1.1%)に心臓逸所を認めた。5例中4例は頸部心臓逸所,1例は胸部心臓逸所であった。頸部逸所心のうち3例の心膜は頸部の皮下を前方へ伸び,その前端は後頭骨,下顎骨,第一頸椎,または前頸部の皮筋や骨格筋などに付着していた。これら3例の胸骨は幅広く扁平で,14-16個の胸骨片で形成されていた。胸部心臓逸所の症例では,胸骨の中央とその部の皮膚に径6cmの欠損があった。心膜は胸骨の欠損口縁に付着し,心臓は胸腔外に裸出していた。

Ectopia cordis was found in five of 451 (1.1%) calves with congenital cardiovascular anomalies. Four of these 5 cases showed cervical ectopia cordis, while the remaining one showed the thoracic form. In three cases of cervical ectopia cordis, the pericardial sac extended anteriorly through the subcutaneous layer of the neck and its cranial end was attached to the occipital bone, mandible, atlas or muscles of the anterior neck. The sternums of these three calves were wide and flat, and consisted of 14 to 16 sternebrae. In the case of thoracic ectopia cordis, the middle of the sternum formed a circular defect with 6 cm in diameter and the overlying skin over this region was also defective. The pericardial sac adhered to the rim of the sternal defect and the naked heart protruded from the thoracic cavity.
