Embolotherapy is the primary treatment for pulmonary arterio-venous malformations
(PAVMs). Approximately, 2-25% of PAVMs demonstrate persistence following embolization.
Early identification and treatment of persistent PAVMs are critical to mitigating
life threatening complications. The presence of prior embolic devices and complex
angioarchitecture of persistent PAVMs pose technical challenges during repeat embolotherapy.
In this article, we review patterns of persistence, factors affecting the persistence,
endovascular treatment techniques, and outcomes.
