Multiple systemic arteries to pulmonary artery malformations: a case description

[摘要] Connections between the systemic circulation and the pulmonary arterial systems are extremely rare. Multiple systemic artery-to-pulmonary artery (SA-PA) malformations, which can be congenital or non-congenital, are extremely rare in people without congenital heart disease. The non-congenital fistulas can develop in patients with inflammatory or infectious disease of the lung and pleura, cancer, or after trauma (1-3). Congenital SA-PA malformations can be detected in patients without any of the risk factors mentioned above. An SA-PA malformation can occur in single or multiple forms and connect the pulmonary vascular bed with the left internal thoracic and the left gastric arteries, the pericardiacophrenic branch of the left musculophrenic artery, the left bronchial artery, or others.
