[Echo-flowmetric control 6 years after percutaneous treatment of varicocele].

Several Authors have discussed the long term efficacy of sclerotherapy; somebody supposes that percutaneous angiographic treatment of spermatic vein is not sure at all because the occlusion due to the sclerosing agents is not retained as long lasting. Studies have been done by other Authors about comparison of recurrent varicocele anatomy following surgery and percutaneous balloon occlusion: it is concluded that venous collaterals are identified easily by renal venography, and knowledge of these collaterals is helpful in planning further radiological treatment. Since 1980 we have always treated left varicocele by means of percutaneous sclerotherapy of the spermatic veins following renal phlebography: the treatment is done on an outpatient basis, in local anaesthesia. Sclerosing agents we usually adopt are: sodium-tetradecyl sulphate and alcohol. At our knowledge long-term results of this treatment have never been published; this is the reason for which long-term follow-up of 27 patients that 6 years ago underwent percutaneous sclerotherapy was done. Only 16 of them have accepted to repeat: a) physical examination; b) Doppler flowmetry; c) scrotal ultrasound. The presence of a varicocele was demonstrated in 2 out of 16 patients (12.5% of the case). These data confirms that percutaneous treatment performed following the procedures we adopted in 1986 has a long term efficacy in 87.5% of the cases.(ABSTRACT TRUNCATED AT 250 WORDS)
