The case of a female patient with Rendu-Osler-Weber disease associated with pulmonary arterio-venous fistula localized at the apical segment of the left inferior pulmonary lobe is described. A decrease in the oxygen arterial saturation (SaO2) at adopting the left lateral decubitus position (left-lateral-decubitodeoxia) was found, as well as an increase in the anatomical venoarterial short-circuit (Qs/Qt) in the same position. The resonsible factors of such changes in SaO2 and Qs/Qt related with the body position are analyzed, and the, exceptional in these patients, finding of alteration of pulmonary mechanics is commented.
本文描述了一例患有遗传性出血性毛细血管扩张症(Rendu-Osler-Weber病)并伴有位于左下肺叶尖段的肺动静脉瘘的女性患者。发现患者在采取左侧卧位时动脉血氧饱和度(SaO2)下降(左侧卧位低氧血症),且在同一位置解剖性静脉-动脉短路(Qs/Qt)增加。分析了与体位相关的SaO2和Qs/Qt发生此类变化的相关因素,并对这些患者中罕见的肺力学改变这一发现进行了评论。
