Uma Causa Rara de Angina Após Revascularização do Miocárdio: Fístula da Artéria Mamária Interna Esquerda para Artéria Pulmonar e Tratamento Bem-Sucedido com Embolização Transcateter com Molas

A 21-year-old, otherwise healthy, female patient was admitted with haemoptysis. Chest X-ray and CT found a consolidated right middle pulmonary lobe. Catheter angiography of ascending aorta visualised two hypertrophic and tortuous branches of the right internal mammary artery with a fistula to the right superior pulmonary vein. The inflow was embolised with coils. Catheter angiography of descending aorta found hypertrophic right bronchial arteries and right phrenic artery supplying a web-like network of vessels, which drained to the right superior pulmonary vein with discrete filling of an accessory right middle pulmonary vein. CT angiography with a catheter for contrast administration in the ascending aorta was performed for characterisation. After two additional episodes of haemoptysis, right middle lobe lobectomy was performed. Perioperatively pulmonary artery blood supply to the right middle pulmonary lobe was absent and an atretic accessory middle pulmonary vein was seen. The patient was discharged 7 days afterwards without sequelae.
