A dairy cow was examined because of extensive obstruction of a teat cistern. The teat was treated by surgical resection of scar tissue, transplantation of an oral-mucosal autograft, and temporary implantation of a silastic tube. The silastic tube became dislodged from the teat, and was surgically removed 30 days after the initial surgery. The cow subsequently had 2 normal lactations. Prior to the third postoperative lactation, the cow developed severe udder edema. During lactation, the surgically treated teat became hard and was difficult to milk. The cow was then culled.
一头奶牛因乳头乳池广泛阻塞而接受检查。通过手术切除瘢痕组织、移植口腔黏膜自体移植物并临时植入硅橡胶管对乳头进行治疗。硅橡胶管从乳头脱出，并在初次手术后30天通过手术取出。这头奶牛随后经历了2次正常泌乳。在术后第三次泌乳前，这头奶牛出现了严重的乳房水肿。在泌乳期间，接受手术治疗的乳头变硬，难以挤奶。随后这头奶牛被淘汰。
