Abstract :
Experimental teat anastomosis for treatment of sever cow’s teat injuries were performed for the first time and evaluated by radiography. Five healthy, non-pregnant milkier Holstein cows were selected and after preoperative considerations, the rear teats were prepared for aseptic surgery. The left teats (1/3 of distal portion) were amputated horizontally, and fullthickness elliptical incisions were induced in 1/3 of proximal of the right teats from the base, in medial aspect. Anastomosis between amputated and neighboring teats was completed with two rows of sutures, simple interrupted in mucosal layer and interrupted horizontal mattress in intermediate and skin layers with polyglactin910(Coated Vicryl),sized 3-0 and 2-0,respectively. Radiographs with meglumine compound (positive contrast media) were prepared under condition of FFD = 80 Cm, 50 Kv, 20 mAs from all anastomised teats with and without positive pressure in 3 day before surgery and 4, 15, 30 and 44 days after the operation. According to radiographic results inner diameter of anastomosis junction were measured 14-20 mm under positive pressure and 11-16 mm without positive pressure in 44th day after the operation. According to the good radiographic findings and simplicity of this surgical technique, Teat anastomosis can be recommend for the treatment of sever teat injuries in dairy cows.
