Obliteration of varicoceles in men with infertility has been shown to improve semen quality and increase fertility rates. Many current techniques involve complex procedures and specialized equipment and may be associated with adverse effects. Transcatheter thermal vessel occlusion was utilized for spermatic vein obliteration in dogs. Diatrizoate (76%) contrast medium at a temperature of 100 degrees C was injected into canine spermatic veins. Follow-up venography and histologic examination revealed thrombosis of the injected veins without damage to the surrounding tissues in all cases. Clinical and laboratory examination of the animals revealed no adverse systemic effects. It is concluded that transcatheter thermal venous occlusion is an effective technique for spermatic vein occlusion in a canine model.
已证明，对患有不孕症的男性进行精索静脉曲张闭塞术可改善精液质量并提高受孕率。目前的许多技术涉及复杂的操作和专用设备，并且可能伴有不良反应。经导管热血管闭塞术被用于犬类的精索静脉闭塞。将温度为100摄氏度的泛影葡胺（76%）造影剂注入犬类精索静脉。随访静脉造影和组织学检查显示，所有病例中注入的静脉均发生血栓形成，而周围组织未受损伤。对动物的临床和实验室检查未发现不良全身影响。结论是，经导管热静脉闭塞术是犬类模型中精索静脉闭塞的一种有效技术。
