Figure 1: Pre- and post-device closure angiographic still frames of pulmonary arteriovenous malformations in the right lower lobe. Top frame shows preintervention angiography of the feeding arterial and draining venous vessels in the medial basal (a and c) and posterior basal (b) pulmonary artery segments. Bottom frame shows post-AVP-IV device closure of the medial basal branches (d and f) and posterior basal (e) pulmonary artery segment images with no residual shunting
