Patients with bilateral aplasia of the vas deferens have been considered sterile. In 2 such patients a segment of great saphenous vein, anastomosed to the globus major, was used to accept and store spermatozoa. Aspirations of the venous cap of the patient B at 1 and 4 months revealed numerous sperm with normal morphology and poor motility. At re-exploration of patient A, 4 months after the original venoepididymal procedure, the venous cap was found to be obliterated by scar tissue yet the epididymal tubules remained dilated. A 12-inch segment of the epididymal tubule was compressed between glass slides to obtain sperm in this patient. However, attempted insemination with this sperm was unsuccessful. Our results with the venous cap are disappointing.
双侧输精管缺如的患者一直被认为是不育的。在2例此类患者中，一段大隐静脉与附睾头吻合，用于接纳和储存精子。对患者B的静脉帽在1个月和4个月时进行抽吸，发现有大量形态正常但活力差的精子。在对患者A进行初次静脉附睾吻合术后4个月再次探查时，发现静脉帽被瘢痕组织阻塞，但附睾小管仍扩张。在该患者中，将12英寸长的附睾小管段夹在载玻片之间以获取精子。然而，用这种精子进行人工授精未成功。我们在静脉帽方面的结果令人失望。
