Resumen

FARFAN-C, Emilio et al. Anomalous Pulmonary Venous Connection. A Case Report. Int. J. Morphol. [online]. 2018, vol.36, n.4, pp.1197-1201. ISSN 0717-9502.  http://dx.doi.org/10.4067/S0717-95022018000401197.

The anomalous connections of the pulmonary veins were first described in 1739. The drainage anomalies of the pulmonary veins are due to an early alteration (day 27-30 of development), during this period the pulmonary venous plexuses are in connection with the cardinal, umbilical and vitelline vein systems. These venous connections return and drain into the left atrium through the common pulmonary vein. In this work we present a partial anomalous pulmonary venous connection. Knowledge of this connection is relevant because it is associated to 80 % of cardiac defects, mainly interatrial communications. During a routine dissection of an adult male cadaver, a vein originating in the left upper lobe was found. The vein originates at the pulmonary hilum in front of the bronchus, with an ascending path of a 10 cm length from the hilum, concluding its trajectory in the left brachiocephalic vein. The anomalous vein drains the left upper lobe of the lung. This anomalous vein originates within the connections of the pulmonary venous system, particularly those found in the left anterior cardinal vein system. This finding highlights the importance and clinical relevance of dissection in the training of health professionals.
