Insights
Pulmonary arteriovenous malformations (PAVMs) can cause cyanosis in children. Endovascular treatment effectively closed multiple PAVMs in a young boy, resolving his symptoms.
Area of Science:
- Vascular Surgery
- Pediatric Cardiology
- Interventional Radiology
Background:
- Pulmonary arteriovenous malformations (PAVMs) are rare vascular anomalies connecting pulmonary arteries and veins.
- PAVMs can lead to severe complications like paradoxical emboli, necessitating timely diagnosis and management in children.
Observation:
- A five-year-old boy presented with persistent cyanosis and clubbing over eight months.
- Imaging and angiography identified multiple, diffuse, bilateral PAVMs.
Findings:
- The patient's PAVMs were successfully treated using an endovascular approach.
- This intervention aimed to eliminate the abnormal vascular connections.
Implications:
- Endovascular treatment is a viable option for complex PAVMs in pediatric patients.
- Prompt management of PAVMs can prevent life-threatening embolic events and improve cyanosis.
Abstract:
Pulmonary arteriovenous malformations (PAVMs) are abnormal vascular connections between the pulmonary arteries and pulmonary veins. Despite their relatively uncommon incidence, PAVMs should be considered in the differential diagnosis of children presenting with cyanosis due to the life-threatening complications posed by paradoxical emboli. The primary management approach involves eliminating the abnormal connections, either through surgical or endovascular methods. We present a case of a five-year-old boy who was seen in the Outpatient Department with cyanosis of the lips and nail beds persisting for eight months. On examination, grade 3 clubbing was noted. Imaging and subsequent angiography revealed multiple bilateral diffuse AVMs, which were treated using an endovascular approach.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
