Advanced sclerotherapy of varicose veins is described in this article using duplex ultrasonographic guidance in three phases of the process. In the presclerotherapeutic stage, patency and competency of the deep venous system are evaluated, location and morphology of the highest point of reflux are determined, luminal and parietal diameters of the target vein, venous compressibility, leaflets of the incompetent valve, and the degree, extent, and velocity of reflux are assessed. In the sclerotherapeutic stage, ultrasonographic guidance is helpful when the anatomy is intricate and points of reflux would otherwise be inaccessible. In the postsclerotherapeutic stage, duplex ultrasonography is indispensable for determination of the extent of the sclerosing reaction, measurement of luminal and parietal diameters, and to elucidate luminal content and its degree of adherence to the venous wall. Duplex ultrasonography provides a sound basis for clinical decision making and thereby enhances the precision and safety of advanced sclerotherapy.
本文介绍了在三个过程阶段使用双功超声引导的静脉曲张高级硬化疗法。在硬化治疗前阶段，评估深静脉系统的通畅性和功能，确定反流最高点的位置和形态，评估目标静脉的管腔和壁直径、静脉可压缩性、功能不全瓣膜的瓣叶以及反流的程度、范围和速度。在硬化治疗阶段，当解剖结构复杂且反流点难以到达时，超声引导很有帮助。在硬化治疗后阶段，双功超声对于确定硬化反应的程度、测量管腔和壁直径以及阐明管腔内容物及其与静脉壁的粘附程度是必不可少的。双功超声为临床决策提供了可靠依据，从而提高了高级硬化疗法的精确性和安全性。
