“…If treatment with particles was to be performed, they have to be very diluted and injected slowly until venous stagnation occurs. In five cases reported by Théron et al [47], this led to a stable occlusion, likewise, in our practice, we saw several patients with a complete and stable occlusion over time using this approach. Liquid embolic agents have the major advantage of being stable, however, their reported complication rates are higher (in the large series approximately 10%), and only rarely a complete obliteration is possible.…”

Spinal vascular malformations are rare diseases with a wide variety of neurologic presentations. Their classification depends on the differentiation of shunting versus nonshunting lesions, the latter being the spinal cord cavernomas. In the shunting lesions, the next step in the proposed classification scheme is related to the feeding artery which can subdivide the dural vascular shunts from the pial vascular malformations: while those shunts that are fed by radiculomeningeal arteries (i.e., the counterparts of meningeal arteries in the brain) constitute the dural arteriovenous fistulas, the shunts that are fed by arteries that would normally supply the spinal cord (i.e., the radiculomedullary and radiculopial arteries) are the pial cord arteriovenous malformations (AVMs; whose cranial counterparts are the brain AVMs). Depending on the type of transition between artery and vein, the latter pial AVMs can be further subdivided into glomerular (plexiform or nidus-type) AVMs with a network of intervening vessels in between the artery and vein and the fistulous pial AVMs. The last step in the classification then describes whether the type of fistula has a high or a low shunting volume which will differentiate the "macro-" from the "micro"fistulas. The proposed classification is therefore based on a stepwise analysis of the shunt including its arterial anatomy, its nidus architecture and its flow-volume evaluation. The major advantage of this approach is that it leads to a subclassification with direct implications on the choice of treatment, thereby constituting a simple and practical approach to evaluate these rare diseases.

“…In the other cases, not included in this series, embolization was recommended, if possible. Thus according to the literature many cases have been treated successfully.25, 42) In contrast to cerebral AVMs and aneurysms, spinal AVMs behave differently after incomplete exclusion either by sugery or embolization.…”

“…But in our experience of endovascular treatments with liquid materials this is an exception. One might presume, that glue embolization can lead to a higher rate of potential complications 17 , such as can be caused by the occlusion of normal vessels and the induced inflammatory reaction.…”
