Treatment of Pulmonary Arteriovenous Malformation in Pregnancy
Clinical Scenario
High-Risk Pregnancy
Pulmonary arteriovenous malformation (PAVM) in a pregnant patient represents a high-stakes clinical situation. Anglo-French guidelines classify these pregnancies as high-risk, requiring a coordinated multiprofessional approach throughout the antenatal and peripartum period.
There is a 1% risk of maternal death in pregnancy among patients with PAVM, underscoring the importance of proactive, structured management rather than expectant observation.
Management Approach
The recommended strategy centres on intervention prior to conception — specifically a form of procedural treatment targeting the malformation itself — alongside a protective measure at the time of delivery.full protocol ›

- However, there is a 1% risk of maternal death in pregnancy, and Anglo-French recommendations are therefore to manage these as 'high-risk' pregnancies involving a multiprofessional approach.
- It is recommended that PAVMs are treated prior to conception.
- Patients with PAVM and their clinicians should be aware that any haemoptysis is potentially life threatening prompting immediate hospital admission and that antibiotic prophylaxis at delivery is required.
