Endovascular venous approach in the treatment of ruptured intra-cerebral arterio-venous malformation

Trans-venous approach has been described for endovascular treatment of many vascular lesions namely the intracranial dural, cavernous and intra-orbital malformations. A patient with a ruptured left deep parietal arteriovenous malformation (AVM) treated with primary transvenous Onyx 18 embolization is reported. Trans-arterial approaches were unsuccessful because of the tiny tortuous feeding arteries and hence a transvenous approach was used for embolization. Follow-up angiography at 3 month revealed persistent angiographic cure of the AVM. Our case illustrates that in patients with ruptured small AVM having a single draining vein, transvenous treatment can be utilized to achieve occlusion resulting in AVM cure.
