Percutaneous microwave coagulation therapy (PMCT) has been widely used as an effective minimal invasive therapy for small liver tumors. The occurrence of a sonographic masked space due to the presence of the lung, however, has become a major obstacle to visualizing the whole tumor in the hepatic dome. To facilitate the use of PMCT for liver tumors in the hepatic dome, we developed PMCT in combination with the artificial hydrothorax method (percutaneous transdiaphragmatic MCT: PTD-MCT). Our new approach for PMCT to the hepatic tumors located in Couinaud's segments VIII or VII just under the diaphragm resulted in a successful treatment. The separation of the lung from the diaphragm by the infusion of saline into the pleural cavity enabled us not only to visualize the whole tumor in the hepatic dome to accurately target the tumor, but also helped us to avoid injuring the lung. PTD-MCT is therefore strongly recommended for the treatment of liver tumors in the hepatic dome.
经皮微波凝固疗法（PMCT）作为一种治疗小肝癌的有效微创治疗方法已被广泛应用。然而，由于肺部的存在导致超声显示出现盲区，这已成为可视化肝顶部整个肿瘤的主要障碍。为便于将PMCT用于肝顶部的肝肿瘤，我们开发了结合人工胸腔法的PMCT（经皮经膈肌微波凝固疗法：PTD-MCT）。我们采用的新方法将PMCT应用于位于膈肌下方的Couinaud肝段VIII或VII的肝肿瘤，取得了成功的治疗效果。通过向胸腔内注入生理盐水使肺与膈肌分离，不仅能使我们可视化肝顶部的整个肿瘤以精确靶向肿瘤，还能帮助我们避免损伤肺。因此，强烈推荐PTD-MCT用于治疗肝顶部的肝肿瘤。
