Pulmonary arteriovenous fistula (PAVF) is an abnormal connection between pulmonary arteries and veins. Patients with PAVF may have the Rendu-Osler-Weber syndrome, a disease transmitted by autosomal dominant mechanisms. Here we describe a case of PAVF in a 56-year-old woman, who was admitted to our department because of dyspnea, hemoptysis, and a mass in the left lower lung found on chest X-ray. The diagnosis of PAVF was suspected according to clinical and physiological criteria and confirmed by magnetic resonance imaging of the chest. The PAVF was removed by left lower lobectomy. Anamnestic and clinical investigations of the patient's relatives led to the diagnosis of the Rendu-Osler-Weber syndrome.

Pulmonary arteriovenous fistula (PAVF) is a rare vascular malformation of the lung that may lead to cyanosis, epistaxis, hemoptysis, and neurological deficits or cerebral abscess. The purpose of this study is to assess the effectiveness of percutaneous transcatheter embolization of PAVF in pediatric patients. Transcatheter embolization of PAVF using spring coils was performed in three patients (two males and one female) who presented between 1989 and 1999. The age at presentation ranged from 8 months to 3 years (mean 19.6 months). All patients had cyanosis and clubbing. Neurological, dermatological, or other cardiac manifestations were absent. The arterial oxygen saturations at presentation ranged from 60 to 72% (mean 64%). During eight procedures, multiple coils (total of 41 coils, average 14 coils per patient) were delivered to occlude the fistulas successfully. There was complete occlusion of the fistulas in all patients after the multiple interventions. The aortic saturations increased from a mean of 66% to a mean of 95%. Chest radiographs demonstrated dramatic regression of the pulmonary shadows in all three patients. There were no complications encountered during the procedures or during follow-up. Transcatheter coil embolization of PAVF is a safe and effective method of treatment in the pediatric age group. Patients may require multiple procedures to completely occlude the fistulas. Long-term follow-up is essential to ensure absence of recurrence due to recanalization.

Pulmonary arteriovenous fistula (PAVF) are rare malformations that may cause serious complications such as paradoxical embolism, stroke, pulmonary hemorrhage and hemoptysis. Accompanying cardiac malformations such as aortic coarctation were not reported previously. Here we present a case of complex PAVF associated with aortic coarctation. The patient was treated successfully by transcatheter embolization of PAVF with amplatzer vascular plug I and II and implantation of a covered CP stent for coarctation at the same session.

Pulmonary arteriovenous fistula (PAVF) is a rare anomaly in the lung, and hemothorax or massive hemoptysis due to spontaneous rupture of the fistula sac is even rarer. The patient described here was a 47-year-old woman who presented with massive hemoptysis resulting from the rupture of her PAVF just after laparoscopic operation. To our knowledge, this may be the first case ever reported that the rupture of PAVF may be correlated with a laparoscopic operation. The patient survived without adverse events after emergency pulmonary lobectomy.
