Isovist间接淋巴造影诊断淋巴水肿(附20例分析)

Indirect Lymphography with Isovist-300 in Various Forms of Lymphedema

为探讨Isovist间接淋巴造影效果,笔者对20例淋巴水肿患者进行间接淋巴造影。此法操作简便,节省时间,反应少,可反复应用,可显示非常细小的初级淋巴管。

Twenty patients with various forms of lymphedema were studied by indirect lymphography. Isovist, a new non-ionic, water-soluble, dimeric contrast media, was used for intradermal infusion, Simultaneous indirect lymphography showed characteristic patterns of lymphatics. The initial lymphatics were visualized by intradermal infusion of the newly, developed isovist. However, they were not opaeified with direct lymphography unless in the presence of valvular insufficiency. No systemic side-effects were observed except for a feeling of discomfort at the injection site. The results showed that indirect lymphography with intradermal infusion of Isovist is useful for demonstrating dermal lymph vessels and for the diagnosis of lymphedema.
