Pulmonary arteriovenous malformations in children
Insights
Pulmonary arteriovenous malformations (PAVMs) are a treatable cause of persistent cyanosis in children. Surgical resection of PAVMs in pediatric patients, particularly those with Rendu-Osler-Weber syndrome, offers a curative outcome.
Area of Science:
- Cardiology
- Pediatric Surgery
- Genetics
Background:
- Pulmonary arteriovenous malformations (PAVMs) are abnormal vascular connections in the lungs.
- PAVMs can lead to life-threatening hypoxemia, presenting as persistent cyanosis in children.
- These malformations are often associated with hereditary hemorrhagic telangiectasia, also known as Rendu-Osler-Weber syndrome.
Observation:
- Three pediatric patients, all female and aged 2-4 years, presented with symptoms suggestive of PAVMs.
- All patients had a family history of Rendu-Osler-Weber syndrome.
- Pulmonary angiography confirmed the diagnosis of PAVMs in all three cases.
Findings:
- The PAVMs were located in various lobes, including the left lower lobe, right upper lobe, and right middle and lower lobes.
- All three patients underwent successful and uneventful surgical resection of the affected lung segments.
- Post-operative recovery was uncomplicated for all patients.
Implications:
- Surgical resection is an effective treatment for pediatric pulmonary arteriovenous malformations.
- Early diagnosis and intervention can prevent severe complications associated with PAVMs.
- Genetic counseling and screening for Rendu-Osler-Weber syndrome are important in affected families.
Abstract:
Pulmonary arteriovenous malformations are a life-threatening, but curable, cause of persistent cyanosis in children. Abnormal communications may be single or multiple and are usually in the lower lobes. Three patients with pulmonary arteriovenous malformations have recently been managed at this hospital. Ranging in age from 2 to 4 yr, all were female, all were from families with Rendu-Osler-Weber syndrome, and all underwent pulmonary angiography with confirmation of diagnosis. All have had uneventful resection, one of the left lower lobe, one the right upper lobe, and the other the right middle and lower lobes.

Overview of Pulmonary Circulation
The process begins with the right ventricle of the heart pumping deoxygenated blood into the pulmonary trunk. This large vessel extends about 5 centimeters before splitting into the left and right pulmonary arteries. These arteries...
