A ten-year-old non-descriptive male dog was presented to Small Animal Surgery Unit of Veterinary Clinical Complex,VCRI, Orathanadu with a history of perineal swelling for past two months.On general clinical examination the dog had normal temperature, congested conjunctival mucous membranes, tachycardia, tachypnoea and enlarged lymph nodes. Per-vaginal examination revealed hard mass in the roof of the vaginal passage and on ultrasonographic examination, a mass measuring around 32.8 x 37.6mm was noticed inside the vagina. The case was tentatively diagnosed as “vaginal tumor” and surgical removal of the tumour was decided. The animal was sedated with inj.dexmedetomidine at the dose rate of 2µg/kg b.wt i.v. and inj. butorphanol at the dose rate of 0.1mg/kg b.wt i.m. Anaesthetic induction was done with inj.ketamine at the dose rate of 5mg/kg b.wt i.v. and inj.diazepam at the dose rate of 0.5mg/kg b.wt i.v. and maintained with isoflurane with variable vaporizer setting and the fresh gas flow at the rate of 20 ml per kg body weight per minute. The cardiopulmonary parameters such as heart rate, respiratory rate, ECG, systolic blood pressure, diastolic blood pressure, mean arterial pressure, saturation of peripheral oxygenation and end-tidal carbon dioxide were monitored and recorded throughout the anaesthetic maintenance. Upon examination of the perineal region, a large mass was observed on the dorsal aspect of the vaginal roof. En-bloc resection of vaginal tumour was performed through dorsal episiotomy. The resected mass was weighing 375gms. Postoperatively the animal was treated with antibiotics, anti-inflammatory drugs along with fluid therapy. The animal made an uneventful recovery.
