Abstract
A 50-year-old female was refered to our hospital because of cough and fever. Chest X-ray and CT scans revealed localized bronchiectasis and pneumonia of the left basal segments. She was treated with antibiotics, but the symptoms continued. Angiography revealed dilated inferior phrenic artery-to-pulmonary artery shunt. Preoperative transcatheter embolization with steel coils was performed. Adhesion between the left lower lobe and the diaphragm was remarkable but ablated smoothly with a small amount of hemorrage, then left basal segmentectomy was performed. In this case, preoperative transcatheter embolization was effective in decreasing intraoperative bleeding.
