Retrograde blood flow can occur in the testicular veins and in the pampiniformis plexus in the absence of valves or if the valves are incompetent, resulting in tortuosity and dilatation of the veins. These abnormal alterations in the anatomy of the veins, termed varicoceles, are associated with infertility in the male. Most varicoceles occur on the left. We report the case of a rare isolated right-sided varicocele in a male evaluated for infertility in whom extensive work-up revealed venous anomalies and a spontaneous porto-systemic shunt. In such cases, standard approaches to infertility treatment are fruitless.
在没有瓣膜或瓣膜功能不全的情况下，睾丸静脉和蔓状静脉丛可出现逆行血流，导致静脉迂曲和扩张。这些静脉解剖结构的异常改变，称为精索静脉曲张，与男性不育有关。大多数精索静脉曲张发生在左侧。我们报告了一例罕见的孤立性右侧精索静脉曲张病例，该男性因不育接受评估，全面检查发现静脉异常和自发性门体分流。在这种情况下，不育治疗的标准方法是无效的。
