A case of sinus venosus atrial septal defect repair of the inferior vena caval type with an unintentional diversion of the inferior vena caval blood to the left atrium is reported. Long-standing, anatomical, right-to-left shunting with cyanosis and hypoxia are associated with systemic and cerebrovascular complications. Cardiac risks depend on the presence or absence of pulmonary hypertension, the associated hematological abnormalities and the degree of anatomical, right-to-left shunting. Cardiac magnetic resonance imaging clarified the etiology of the unexplained cyanosis and delineated the surgical anatomy.
报道了一例下腔静脉型静脉窦房间隔缺损修复病例,术中意外出现下腔静脉血向左心房分流。长期存在的解剖学上的右向左分流伴发绀和缺氧与全身及脑血管并发症相关。心脏风险取决于是否存在肺动脉高压、相关血液学异常以及解剖学上右向左分流的程度。心脏磁共振成像明确了不明原因发绀的病因并描绘了手术解剖结构。
