ABSTRACT
Various techniques for the endovascular treatment of dural arteriovenous fistulas (dAVFs) of the transverse and sigmoid sinus have recently evolved. Transvenous coil occlusion of the involved segment and transarterial embolization of the feeding arteries with liquid agents are the commonest treatments utilized. However, with respect to venous hypertension as the probable pathogenic cause of this disorder, a nonocclusive or remodeling technique might be preferable. We will present a series involving four patients, treated with transvenous angioplasty and stent deployment as a definitive treatment of dAVFs of the transverse and sigmoid sinus. This method was used as a primary treatment or as an adjunct to previous noncurative transarterial n-butyl cyanoacrylate and particle embolization. In three of the four cases, complete occlusion of the fistula was achieved with confirmation of occlusion seen on follow-up angiographical studies. In one case a negligible and nonsymptomatic remnant of the fistula fed by the tentorial artery was left untreated. From our experience, we conclude that transvenous stent deployment is an alternative to traditional concepts. Additionally, the pathological theory of dAVFs in this region located in venous pouches of the sinus wall is supported by the fact that they can be occluded by mechanical compression during angioplasty and subsequently maintained by a stent.
