Abstract:

Partial anomalous pulmonary venous return (PAPVR) was firstly described by Winslow in 1739 and is a congenital situation. Two conditions are discussed: Pulmonary veins incorrectly drain into the superior vena cava (SVC) or directly into right atrium (RA). Cardiac magnetic resonance imaging (MRI) or CT can be prefered to project the anomalous veins because of giving the more reliable result. Also, CT helps in better identification of the anatomy of the pulmonary vein and its tributaries. In cases requiring surgical intervention and treatment plan or treatment approach, it is important to diagnose this anomaly, to know the accompanying cardiac anomalies and to have the chance for early treatment, as surgeons, radiologists and clinicians should keep in mind the possibility of such anatomical variations. As a result, the awareness of the PAPVR anatomy provide to prevent the vessel damage. Early surgical repair is a choice of the treatment in symptomatic patients. Whereas, in severe patients, early and aggressive pulmonary vasodilator therapy may be suggested.
