Pulmonary Arteriovenous Malformations in a 18-months-old Child: A Case Report.

Pulmonary Arteriovenous Malformation (PAVM) is a cardiovascular anomaly in which an anatomic communication between the pulmonary artery and pulmonary vein is formed, resulting in an additional cardiac shunt from right to left side. PAVM is a rare disease, reported more in females, but in newborns comparatively higher in males. Cases can vary from asymptomatic to symptomatic such as having dyspnoea, hypoxia, cyanosis, neurological symptoms. They are mostly congenital having association with Hereditary Haemorrhagic Telangiectasia (HHT). Herby, author present a case of 18-months-old female admitted with peripheral cyanosis in the Paediatric Department. Her saturation level was 76%, after admission she received three doses of salbutamol nebulisation and was kept on 3 litre oxygen until her saturation increased to around 95%. On auscultation, a murmur of grade 2/6 heard in the left axilla with clear lung fields. Chest X-ray detected a prominent lobulated opacity in the left sided lung adjacent to the heart border. An echocardiogram was done which turned out normal. Thoracic Computed Tomography (CT) scan with contrast showed a vascular malformation in the apical region of the left lower lobe. Pulmonary angiography showed multiple vascular lesions in the peripheries which was consistent with arteriovenous malformation. The child was diagnosed with PAVM. A transcatheter embolisation and coil closure of AVM was performed and postprocedure the child was stable. [ABSTRACT FROM AUTHOR]
