Vein of Galen technique for occluding the aneurysmal sac of pulmonary arteriovenous malformations.
In seven of 255 consecutive patients (2.7%) who underwent pulmonary arteriovenous malformation (PAVM) embolization at our center between July 1, 1996, and July 1, 2000, the feeding artery was considered too short for safe occlusion with use of standard stainless-steel coils or detachable balloons. These patients were successfully treated with use of a modified vein of Galen technique similar to the one used for managing intracranial vein of Galen aneurysms. In this article, the authors report their experience with this technique in safely occluding the aneurysmal sacs of PAVMs in patients with short (<2 cm) feeding pulmonary arteries.
