To evaluate hemostasis of the ovarian arteriovenous complex (OAVC) in relation to surgical time, practicality and feasibility in three ovariohysterectomy (OH) techniques for queens.
The experiment was performed on 21 female cats aged between six months and seven years, randomly arranged into three groups in a completely randomized design. Group one was spayed using the conventional three-clamp technique, group two using the OAVC knotting technique, and group three using the ovarian pedicle rotation technique. The student's t-test and Tukey's test were used to compare the mean surgical times.
The conventional technique, which uses thread wires, was more laborious and required longer execution time compared to the other two techniques. The OAVC knotting technique was the fastest and had the least blood loss.
The use of techniques that do not use synthetic materials for OAVC hemostasis was proven to be appropriate in castration projects, provided that the surgical team has sufficient training.
评估在三种母猫卵巢子宫切除术（OH）技术中，卵巢动静脉复合体（OAVC）的止血效果与手术时间、实用性和可行性的关系。
本实验在 21 只年龄在 6 个月至 7 岁之间的雌性猫身上进行，采用完全随机设计将其随机分为三组。第 1 组采用传统的三夹技术进行去势，第 2 组采用 OAVC 结扎技术，第 3 组采用卵巢蒂旋转技术。采用学生 t 检验和 Tukey 检验比较平均手术时间。
与其他两种技术相比，使用缝线的传统技术更费力，需要更长的执行时间。OAVC 结扎技术最快，出血量最少。
在绝育项目中，使用不使用合成材料进行 OAVC 止血的技术被证明是合适的，前提是手术团队有足够的培训。
