Patent ductus arteriosus coexisting with a left brachiocephalic artery originating from the descending aorta: A case report.

Rational: Patent ductus arteriosus (PDA) and a coexisting left brachiocephalic artery originating from the descending aorta is an extremely rare anomaly of unknown etiology. Patient concerns: Herein we report a 3-year-old female who was found to have this condition during intervention process to close PDA. Diagnosis: The patient was diagnosed with PDA coexisting with left brachiocephalic artery through angiography. Intervention: Intervention involved transcatheter closure of the pulmonary side of PDA with coils. Outcomes: At 6-months follow up, the patient was well, with no symptoms and normal flow through the left carotid artery. Lessons: PDA coexisting with left brachiocephalic artery originating from the descending aorta is a very rare anomaly. When this variety of PDA is closed, it is important to avoid affecting the blood flow in the left brachiocephalic trunk. For this reason, closure on the side of the pulmonary artery may be the best solution
