Spinal epidural arteriovenous fistulas: arterial and venous approaches to embolization.
نویسندگان
چکیده
The authors describe two patients with multiple spinal arteriovenous fistulas and exclusive epidural venous drainage. Both presented with a myelopathy caused by compression by large epidural veins. Both had arterial embolizations, but one required a venous approach to achieve a stable clinical result.

Spinal osseous epidural arteriovenous fistula with multiple small arterial feeders converging to a round fistular nidus as a target of venous approach.
We present two patients with spinal epidural arteriovenous fistulas involving the vertebral body recruiting dural and osseous branches as feeders. The fistulas, forming a round venous sac into which the multiple arterial feeders converge, were located near the round bony defect of the vertebral body, suggesting the osseous component of this vascular lesion. Transvenous coil embolization of the ...
متن کاملDirect percutaneous venous puncture and embolization of giant perimedullary arteriovenous fistulas.
PMAVFs are rare entities that are formed by a direct communication between an artery that feeds the spinal cord and a vein. The goal of treatment is to occlude the shunt; this is done endovascularly either from an arterial or a venous approach. When these approaches are not possible, direct percutaneous puncture of the draining veins may be attempted to embolize the arteriovenous shunt directly.
متن کاملTransvenous embolization as the primary therapy for arteriovenous fistulas of the lateral and sigmoid sinuses.
PURPOSE We report on the evolution in one institution from transarterial embolization for the treatment of dural arteriovenous fistulas of the lateral and sigmoid sinuses to the safer and more durable technique of transvenous endovascular therapy for the majority of these lesions. METHODS Arterial, venous, and combined embolizations were performed for 24 fistulas of the lateral and sigmoid si...
متن کاملCASE REPORT Double Spinal Dural Arteriovenous Fistulas
A. El-Serwi A. Maubon J. Vidal R. Chapot SUMMARY: We present a patient with double spinal dural arteriovenous fistulas revealed by progressive myelopathy. Numerous dilated veins extending along the entire length of the spinal cord were found on MR imaging. Angiography showed a first spinal dural fistula at the level of T7 with descending venous drainage and a second spinal dural fistula at the ...
متن کاملOnyx transarterial embolization of dural arteriovenous fistula for failed N-butyl cyanoacrylate treatment: case report
Total occlusion of dural arteriovenous fistulas (DAVFs) via transarterial embolization is difficult due to the rich anastomotic network of the dural/falcine plethora of feeding arteries, blood supply to cranial nerves, and extracranial to intracranial anastomoses. Incomplete occlusion of the fistulas will result in recanalization of the DAVF from the multiple collateral arteries constituting th...
