By using coils, balloons, particles or sclerosing agent, the interentional radiologist blocks the blood flow in the ein, which reduces pressure on the aricocele. 通过使用线圈，球囊，颗粒或硬化剂，介入放射学家可以阻断静脉的血流，从而可以降低精索曲张静脉的压力。
In this study, we treat the PWS lesions with sclerosing agent injection first for several times, and then combine with dye laser treatment to get better results. 本研究利用硬化剂在血管红色母斑做病灶内注射之后，再合并染料雷射治疗，预期能得到比原先用单纯的染料雷射治疗有更好的疗效。
