title: Interest and necessity of combined neuroradiological and neurosurgical treatment in some cases of dural arterio-venous fistulae.
abstract: The authors report 3 observations of dural arterio-venous fistula cured by combined neuroradiological and neurosurgical intervention. In the first case, the shunt affected the left lateral sinus. Repeated embolizations failed whilst intracranial hypertension developed, as a consequence of flux in the opposite lateral sinus and in the sagittal sinus. Surgical intervention, consisting in isolation of the transverse sinus, led to complete cure, after a one month delay. In the second case, the shunt was adjacent to the sagittal sinus, right parietal, and had led to an intracerebral haematoma, by rupture of an arterialized cortical vein. Embolizations alone could not cure the fistula which therefore had to be excised. In the third case, the shunt was located in the falx, at the parieto-occipital junction, and was responsible for arterialization of cerebral veins in the right parieto-occipital region. For this reason, after failure of endovascular treatment, the fistula was coagulated, with subsequent complete cure. These three cases illustrate the different types of drainage of such arterio-venous fistula, and their corresponding neurological symptoms and signs, complications and risks, that required a radical-not only clinical, but also anatomical-cure. This aim was achieved when embolizations were accompanied by direct surgical attack.
