对5例肝性胸水初步进行了分析。其发病机理主要是由于胸膜淋巴管压力增高或破裂,淋巴液渗入或漏至胸膜腔;腹压的增高造成横膈过度伸展,导致穿孔,腹水直接进入胸腔。诊断主要需与结核性胸膜炎相鉴别。治疗主要控制、减少腹水增长。胸腔留置导管排除胸水的效果有待进一步实践证实。 Five cases of hepatic hydrothorax were initially analyzed. The pathogenesis is mainly due to increased pressure or rupture of the lymphatic capillaries, lymphatic leakage or leakage to the pleural cavity; increased diaphragmatic overdress caused by excessive stretching, leading to perforation, ascites directly into the chest. The main diagnosis should be differentiated from tuberculous pleurisy. The main treatment control, reduce ascites growth. Pleural indwelling catheter to exclude the effect of hydrothorax to be confirmed by further practice.
