Endovascular treatment of cerebral arteriovenous malformation (AVM) lies in selective catheterisation through feeder and AVM nidus. Sticking mixture is applied after proper verification of microcatheter location. Malformation embolisation is normal when the vessel net is of small diameter. In the presented case embolisation material penetrated cerebral vein system and then lungs, where numerous emboli developed. X-ray where confirmed pulmonary embolism resulted in severe respiratory insufficiency. Treatment of this rare complication as well as the cause of its occurrence have been presented.
