Transarterial Embolization for Pulmonary Arteriovenous Malformation: A Systematic Review and Meta-Analysis
π **Clinical Question:**
Does an updated meta-analysis continue to show that transcatheter embolization for treatment of pulmonary arteriovenous malformations (PAVMs) is safe and effective? What additional insights does it offer?
π‘ **Key Insight:**
Transcatheter embolization for pulmonary arteriovenous malformations demonstrated a high technical success rate (>98%), whereas the reported rate of postembolization catastrophic events was low (1.0%). The use of vascular plugs was associated with significantly lower persistence rates than coils only (13.6% vs 32.7%).
Venous sac embolization showed a markedly lower persistence rate than feeding artery embolization (3.8% vs 24.3%).
π **Why it matters:**
PAVM embolization, especially using vascular plugs and encompassing venous sac embolization, has favorable technical and treatment success rates and low risk of severe AEs.
