N-Butyl cyanoacrylate embolization of an extremely rare variant of sequestration complex - a high-flow left-to-left shunt between systemic artery and pulmonary vein.

Unlabelled: A 19-year-old female presented with hemoptysis. Computed tomography (CT) pulmonary angiography revealed aberrant vessels from descending thoracic aorta, draining into pulmonary veins (left-to-left shunt). She was managed by transcatheter embolization of the aberrant vessels using N-butyl cyanoacrylate (NBCA) with balloon occlusion.
