Figure 1.

(A–D) Patient with massive epistaxis who has had three embolizations of the internal maxillary artery branches on both sides. The arteriography of the internal carotid artery shows the presence of a thick infraorbital artery that reaches the nostril and depends on the ophthalmic artery. After the catheterization of the ophthalmic artery, a microcatheter is inserted distally to the origin of the retinal branches; 150 to 300 microparticles were used. During the embolization a retrograde opacification of the whole ophthalmic artery was observed. An arteriography was performed from the internal carotid artery, which showed complete occlusion of the ophthalmic artery. The patient lost the vision in his left eye. There were no further episodes of epistaxis.
