To describe varicose vein as a cause of obstruction of the teat cistern in dairy cattle and to report therapeutic options and outcome.
Retrospective case series.
Dairy cows (n = 22).
Medical records (1998-2011) of dairy cows admitted for milking difficulties caused by a teat varicose vein were reviewed. Three treatment approaches were used: sclerotherapy, ligation of the vein associated with sclerotherapy, and phlebectomy. Long-term outcome was obtained ≥ 6 months after treatment and defined as a milking improvement. Descriptive statistics were used to determine the population at risk and a chi square test was used to evaluate the relationship between treatments and outcomes.
Twenty-four teats (22 cows) had a varicose vein. Forequarters were more frequently affected than rear quarters (P < .01). Three sclerotherapies, 12 ligations associated with sclerotherapy and 6 phlebectomies were performed. Five veins were not treated. Overall prognosis with treatment was good (84%) at ≥ 6 months and was not significantly different between treatment types (P = .38). Recurrence of the obstruction by the varicose vein occurred in 3 of 19 teats.
Several surgical options are available for treatment of teat varicose veins. The overall prognosis of return to normal milking is good.
描述乳牛乳腺池阻塞的一个病因——静脉曲张，并报告治疗方法及结果。
回顾性病例系列研究。
奶牛（n = 22）。
回顾1998年至2011年因乳头静脉曲张导致挤奶困难而收治的奶牛的病历。采用了三种治疗方法：硬化疗法、与硬化疗法联合的静脉结扎术和静脉切除术。在治疗后≥6个月获得长期结果，并将其定义为挤奶情况改善。使用描述性统计来确定有风险的群体，并使用卡方检验来评估治疗与结果之间的关系。
24个乳头（22头奶牛）出现静脉曲张。前乳房比后乳房更常受到影响（P <.01）。进行了3次硬化疗法、12次与硬化疗法联合的结扎术和6次静脉切除术。5条静脉未治疗。治疗后≥6个月时总体预后良好（84%），且不同治疗类型之间无显著差异（P = 0.38）。19个乳头中有3个出现静脉曲张导致的阻塞复发。
有几种手术方法可用于治疗乳头静脉曲张。恢复正常挤奶的总体预后良好。
