Anomalous pulmonary venous return: Pictorial review

Purpose or Case Report: The purpose of this exhibit is to review imagings findings of anomalous pulmonary venous return on angiotomography and describe anomalies associated.

Magnetic resonance (MR) imaging and computed tomography (CT) are used in diagnostic and follow – up the congenital vein anomalies. CT provides superior spatial resolution and short time but there is exposure to ionizing radiation. However in many hospital there are only the possibility of obtain CT imaging in neonates and infant.
The total anomalous pulmonary venous return (TAPVR) is the result of failure of the common pulmonary vein to connect to the left atrium with persistence of the primitive splanchnic connections of the pulmonary veins. There are four categories: supracardiac, cardiac, infracardiac and mixed.
The partial anomalous pulmonary venous return (PAPVR) occurs when some but not all segments of the developing lung failed to establish connections with the common pulmonary vein.
Methods & Materials: A retrospective review of CT scan of patients with the diagnosis of anomalous pulmonary venous return was performed in a pediatric reference institute from January 2014 though October 2015.
Results: We found 29 patients with the diagnosis of anomalous pulmonary venous return, 6 were excluded for having postoperative changes. The average age was 17,8 months (11days – 7 years). We found slight predominance of females patients (52%). TAPVR was found in 78%, and the majority of the patients had supracardiac TAPVR ( 56% of TAPVR) as describe literature. We also found infracardiac TAPVR, intracardiac TAPVR, mixed TAPVR, intracardiac PAPVR and scimitar syndrome. CT findings of these entities will be collected and widely described.

The more anomalies associated were atrial septal defect (52%), ductus venosus(30%) and heterotaxy (23%). Other anomalies found are ventricular septal defect, double outlet RV/LV, atrioventricular canal, estenosis / atresia of the pulmonary artery , aberrant subclavian artery. Also we found transposition of the great arteries, aortic coartation, and others.
Conclusions: There are a variety of anomalous pulmonary venous return and abnormalities associated. Knowledge of these entities can help the radiologists to differentiate between these venous congenital anomalies for timely and accurate diagnosis.
