Embolization of pulmonary arteriovenous malformation causing hypoxemia in a 7-year-old child
Pulmonary arteriovenous fistulas are abnormal vessels joining the right pulmonary artery to the pulmonary veins. They lead to an extracardiac right-to-left shunt with refractory hypoxemia. We report the case of a 7-year-old girl with a large pulmonary arteriovenous fistula discovered with refractory hypoxemia diagnosed during general anesthesia for adenoidectomy. Radio-opacity was observed on the upper lobe of the right lung. The diagnosis was made using thoracic angiotomography. The proximal arterial vessel arose from the lobar pulmonary artery. The fistula had developed in the entire right upper lobe and drained into two veins flowing into the right superior pulmonary artery. Given the marked hypoxemia, the potential risks of pulmonary hemorrhage and pulmonary infection, an occlusion of the fistula was indicated. After discussion between surgeons and interventional cardiologists, catheterization was indicated. The occlusion of the fistula was successful at the second attempt after release of a vascular plug in the main proximal vessel. This case illustrates the clinical circumstances of diagnosis of arteriovenous fistula, the diagnostic algorithm for refractory hypoxemia and the therapeutic options, with discussion of the benefits and drawbacks of a catheterization procedure..
