This report presents the case of a nine-month-old bitch with incomplete occlusion of the skin and mucosa between the anus and dorsal commissure of the vulva. This anomaly, known as anovulvar cleft, was associated with a vaginal prolapse-hyperplasia. Anovulvar cleft is a rare condition in bitches and is caused by incomplete closure of the dorsal urogenital folds. Anovulvar cleft can lead to clitoritis, abrasion, dryness and devitalisation of the smooth exposed mucosa. Surgery can correct the condition. In the present study, surgical resection of the hyperplasic vaginal tissue associated with perineoplasty using an inverted V-shaped incision showed excellent results. An ovariohysterectomy was also performed to prevent recurrence of the vaginal prolapse-hyperplasia.
本报告介绍了一只9个月大母犬的病例，该犬肛门与阴门外背侧连合之间的皮肤和黏膜存在不完全闭合。这种异常情况称为肛门外阴裂，与阴道脱垂-增生有关。肛门外阴裂在母犬中是一种罕见病症，由泌尿生殖背褶不完全闭合引起。肛门外阴裂可导致阴蒂炎、擦伤、光滑外露黏膜干燥和坏死。手术可矫正该病症。在本研究中，采用倒V形切口进行会阴成形术并切除增生的阴道组织，效果极佳。还实施了卵巢子宫切除术以防止阴道脱垂-增生复发。
