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

AbstractA 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. A systemic artery to pulmonary vein fistula is one of the least common congenital anomalies. Most of the reported cases have been managed by surgery. Only a few patients have been treated by transcatheter embolization, using coils or vascular plugs as the embolizing agents. To our knowledge, this is the first case of its kind that was managed by glue embolization. Favorable post-procedure results have led us to believe that glue embolization can be considered a suitable alternative to thoracotomy in such patients.
