Summary
Pulmonary arteriovenous malformations (PAVMs), often linked to hereditary haemorrhagic telangiectasia, typically cause shortness of breath. Transcatheter embolisation is a safe and effective treatment, largely replacing surgery for PAVMs.
Area of Science:
- Vascular Medicine
- Interventional Radiology
Background:
- Pulmonary arteriovenous malformations (PAVMs) are uncommon vascular anomalies.
- Hereditary haemorrhagic telangiectasia (HHT) is frequently associated with PAVMs.
Observation:
- Exertional dyspnoea and hypoxaemia are common clinical symptoms.
- Screening for PAVMs often involves the 100% oxygen method.
Findings:
- Pulmonary angiography is crucial for anatomical definition and guiding transcatheter embolisation (TCE).
- TCE is a highly effective and safe procedure for PAVMs with a low recanalisation rate.
- TCE has become the preferred treatment, largely supplanting surgical interventions.
Implications:
- TCE offers a minimally invasive and successful therapeutic option for PAVMs.
- Computed tomography (CT) of the chest aids in monitoring asymptomatic PAVMs and post-TCE patients.
