The phenomenon of abnormal pulmonary arteriovenous connections in patients with acquired lung disease rarely has been reported. We report three patients with acquired lung disease and hypoxia that did not respond to the administration of 100 percent oxygen. Contrast-material-enhanced echocardiography demonstrated intrapulmonary right-to-left shunting in all three patients. These cases suggest that patients with hypoxia due to acquired lung disease may be screened by contrast-enhanced echocardiography to identify the presence and the location of anatomic right-to-left shunts.
获得性肺部疾病患者出现异常肺动静脉连接的现象鲜有报道。我们报告了3例获得性肺部疾病且伴有低氧血症的患者，这些患者对给予100%氧气治疗无反应。对比剂增强超声心动图显示所有3例患者均存在肺内右向左分流。这些病例提示，对于因获得性肺部疾病导致低氧血症的患者，可通过对比增强超声心动图进行筛查，以确定解剖学右向左分流的存在及其位置。
