Partial Left Pulmonary Artery Sling

caused by a vascular ring (Figure 1). Angiographic reconstructions were carried out in anterior (Figure 2) and lateral (Figure 3) views. The main pulmonary artery (MPA) divided to form the right pulmonary artery (RPA) and a left pulmonary artery (LPA) that mainly irrigated the upper lobe. Another left pulmonary artery that originated in the right pulmonary artery (LPA-R) ran behind the trachea and preferentially irrigated the inferior lobe. At the time of writing, the patient is pending surgery. The proposed technique is to disinsert the artery from its anomalous origin, uncross it from the bronchus, and reinsert it in the LPA.
