Using serial perfusion lung scans, we have documented the opening up and closure of right-to-left intrapulmonary arteriovenous shunts over a period of several weeks in a patient with chronic alcoholic liver disease. The presence of the shunts correlates well with the severity of hypoxemia and the presence of nodular mottling on chest radiographs. The time course of these changes with clinical status suggests lability and the functional nature of these shunts.
通过连续灌注肺扫描，我们记录了一名慢性酒精性肝病患者在数周时间内右向左肺内动静脉分流的开放和关闭情况。分流的存在与低氧血症的严重程度以及胸部X线片上结节状斑片影的存在密切相关。这些变化随临床状态的时间进程提示了这些分流的不稳定性和功能性本质。
