A pregnant heifer with a congenital incompletely developed vulva

A 2 year old Friesland heifer was presented in an advanced stage of pregnancy with a vulva showing only 2 small openings of 1,5 and 0,5 cm in diameter in the dorsal and ventral vulvar commissures, respectively. Normal vulvar skin covered a thick band of fibrous tissue between the two openings. From the vestibulum forward, the rest of the genital tract was normal. At calving, the fibrous tissue was resected under epidural anaesthesia, and the calf delivered with ease. The vulva was reconstructed by stitching the vestibular mucosa to the vulvar skin using simple interrupted sutures.
