The MVP device was selected because it can be used as a single occlusion device, resulting in faster procedural times and minimal CT artifact.
The MVP devices were deployed and demonstrated immediate occlusion of each PAVM. Multiple PAVMs could be treated during the same procedure with limited radiation exposure for the patient and the operator.
34-year-old female presented for evaluation of a suspected pulmonary arteriovenous shunt, discovered on contrast-enhanced echocardiography during workup of a right posterior circulation stroke six months prior.
She reported daily epistaxis and recurrent headaches and migraines but no breathlessness or previous history of hemoptysis.
Four MVP devices were used to treat one small and three large PAVMs.
