Interventional treatment of pulmonary arteriovenous malformations

Figure 1 Simple pulmonary arteriovenous malformations with one afferent (feeding) artery and one efferent (draining) vein. PAVM: Pulmonary arteriovenous malformations.

Figure 2 Complex pulmonary arteriovenous malformations. A: Two afferent (feeding) arteries (arrows); B: After embolization with balloon in one feeding artery (arrows) and coils in the other.

Figure 3 Multiple pulmonary arteriovenous malformations. A: In both lungs; B: Multiple pulmonary arteriovenous malformations (PAVM) after embolization. One small PAVM on the right side has been left untreated because of small sized feeding artery (arrow).

Figure 4 Pulmonary arteriovenous malformations in both lungs, visible on the chest X-ray.

Figure 6 Simple pulmonary arteriovenous malformations. A, B: Before embolization; C: After selective catheterization of the feeding artery; D: After embolization with coils (arrow).
