“…1 It follows an anomalous route through the lungs and drains normally into the left atrium. [1][2][3][4] Therefore, the meandering pulmonary vein belongs to category 2. Anomalous unilateral single pulmonary vein (AUSPV), pseudo-scimitar syndrome, and pulmonary varices also belong to the same category.…”

“…1,3,4,6,[8][9][10][11][12][14][15][16][17] Normally, during the 2 months in utero the lung buds develop from the foregut and drain the systemic veins of the embryo, including the cardinal and umbilicovitelline veins. At the same time, an outpouching from the primitive left atrium forms a common pulmonary vein and extends toward the lung venous plexus.…”

Meandering pulmonary veins with a common inferior trunk: an anomalous left inferior pulmonary vein entering an anomalous right inferior pulmonary vein

We report an unusual case of an asymptomatic 56-year-old woman in whom an anomalous left inferior pulmonary vein was noted to drain into the meandering right inferior pulmonary vein and the common inferior vein normally entered the left atrium. These findings were confirmed by three-dimensional computed tomography. To the best of our knowledge, this is the first reported case of meandering pulmonary veins with a common inferior trunk.

“…The classic type is characterized by the presence of a single vein from the right lung that descends inferiorly and posteriorly to drain into the inferior vena cava (IVC). In less common variants, the anomalous venous channel has dual drainage into the left atrium (LA) and the IVC [1][2][3] or a "meandering" anomalous right pulmonary vein draining into the LA [4,5]. We present a case in which the scimitar vein had dual drainage to the IVC and LA.…”

In the young adult, the symptomatology of partial abnormal infradiaphragmatic pulmonary venous return is often very nonspecific. However, this condition may sometimes be diagnosed when the classic scimitar image is found.' Occasionally, this abnormal type of venous return can be a component of a larger malformation syndrome: the scimitar which includes dextroposition of the heart, hypoplasia of the right lung (associated with various degrees of bronchial and vascular anomalies), and diaphragmatic malformation. Angiography remains the method of choice for confirmation of the diagnosis and for preoperative assessment, especially for the associated cardiac anomalies. We report a case of a young adult with infradiaphragmatic venous return diagnosed by ultrasonography. Real-time ultrasonography can easily and precisely demonstrate the transdiaphragmatic trajectory of the aberrant pulmonary vein and its confluence with the inferior vena cava. CASE REPORTA 16-year-old male presented with a history of cardiac murmur since birth and slight dyspnea on exertion. Auscultation revealed a systolic murmur (2/6) at the second left intercostal space with persistent splitting of the second heart sound. The electrocardiogram showed signs of right ventricular hypertrophy. The chest X-ray ( Fig. 1) revealed discrete dilatation of the right side of the heart and, at fluoroscopy, bulging and pulsatile shadows of the hilum. A curvilinear scimitar image could be suspected behind the right heart cavities. M-mode sonography revealed moderate dilatation of the right ventricle, normal movement of the interventricular septum, and normal dimensions of the left atrium. There was no echofree space behind the left atrium. Heart catheterization showed abnormal oxygen saturation in the blood found in the lower part of the right atrium (pulmonaryhystemic output ratio: 1.5). An angiogram confirmed partial abnormal pulmonary venous return; all the veins of the right lung coalesced into a "collecting vein" that drained into the inferior vena cava at the level of the diaphragm (Fig. 2).To better evaluate the site of the opening of the collecting vein into the inferior vena cava in relation to the diaphragm, a n abdominal ultrasound investigation was carried out (mechanical 3.5 MHz sector scan). This procedure readily demonstrated the lower thoracic and abdominal trajectory of the anomalous pulmonary vein; the opening of this vessel into the inferior vena cava was located just below the diaphragm and behind the ostia of the hepatic veins [Figs. 3 and 4(A)1. No diaphragmatic malformation was found nor was a systemic artery with a transdiaphragmatic trajectory visualized.At surgery, confirmation was made of the position of the collecting vein's entry into the inferior vena cava (just below the diaphragm); the collecting vein was reimplanted in the left atrium by means of a prosthetic enlargement of this cavity. 425
