Pulmonary veins carry oxygenated blood from lungs to the left atrium of the heart. The anatomy of the pulmonary veins is variable with some anatomic variants. In clinical practice the difference between the normal anatomy of pulmonary veins with its variants and abnormal anatomy is very important for clinicians. Variants of pulmonary veins may occur in number, diameter and normal venous return. We present a case report and a review of the literature with the pulmonary venous return that deviates from the usual anatomical configuration and ranges from normal variant drainage to anomalous pulmonary-systemic communication. Initially, it was considered as an anatomical variant of the pulmonary venous return associated with the persistence of the left superior vena cava. Upon detailed exploration it was established that it was an anomaly of the pulmonary venous return which led in time to the installation of its complications. Diagnosis can be difficult, sometimes missed, or only made late in adulthood when complications were installed. Knowledge of variant anatomy and anomalous pulmonary venous return play a crucial role in the diagnostically challenging patient.
肺静脉将含氧血液从肺部输送到心脏的左心房。肺静脉的解剖结构存在变异，有一些解剖学变体。在临床实践中，肺静脉正常解剖结构及其变体与异常解剖结构之间的差异对临床医生非常重要。肺静脉的变体可能在数量、直径和正常静脉回流方面出现。我们呈现一例病例报告并对文献进行综述，内容涉及偏离通常解剖结构的肺静脉回流，范围从正常变异引流到异常肺 - 体循环交通。最初，它被认为是与左上腔静脉持续存在相关的肺静脉回流的解剖学变体。经过详细探查，确定它是肺静脉回流异常，最终导致了并发症的出现。诊断可能困难，有时会被漏诊，或者直到成年出现并发症时才得以诊断。了解变异解剖结构和异常肺静脉回流在诊断具有挑战性的患者中起着至关重要的作用。
