By using coils, balloons, particles or sclerosing agent, the interentional radiologist blocks the blood flow in the ein, which reduces pressure on the aricocele. 通過(guò)使用線(xiàn)圈，球囊，顆?；蛴不瘎?，介入放射學(xué)家可以阻斷靜脈的血流，從而可以降低精索曲張靜脈的壓力。
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. 本研究利用硬化劑在血管紅色母斑做病灶內注射之后，再合并染料雷射治療，預期能得到比原先用單純的染料雷射治療有更好的療效。
