Objective: To reveal the deep venous lesions in the patients who suffered varicocele.Methods: Since the bilateral varicocele patients who had undergone the varicocele surgery often presented a dissatisfactory outcome.Meanwhile,some patients with unilateral varicocele relapsed after the surgery.So,the two kinds of patients were collected in this research.The method to reveal deep venous lesions is direct computed tomography venography(DCTV).Results: The bilateral varicocele patients had a relatively high rate of discovered deep venous anomaly by DCTV.And the relapsed patients received surgery could be found lack of collateral circulation of internal iliac vein and spermatic cord vein.Conclusions: The deep venous lesions should be considered before any kind of spermatic cord vein ligation.The bilateral varicocele and relapse patients underwent ligation were suggested to do DCTV exam.
