Spinal dural arteriovenous fistulas: evaluation with MR angiography.
To show that postgadolinium three-dimensional time-of-flight MR angiography shows abnormal intradural vessels associated with spinal dural arteriovenous fistula better than routine MR imaging and provides screening information useful for subsequent diagnostic conventional angiography and/or posttreatment evaluation. ⋯ Postgadolinium, spinal MR angiography in cases of suspected dural arteriovenous fistula provides information about intradural veins that supplements the diagnostic value of the MR imaging results, facilitates the subsequent digital subtraction angiography study, and, in treated cases, reflects the success of surgery and/or embolization.

Endovascular treatment of fusiform aneurysms with stents and coils: technical feasibility in a swine model.
To assess the biomechanical feasibility of treating experimental fusiform aneurysms endovascularly with a combination of stents and coils. ⋯ Endovascular treatment of experimental fusiforms aneurysms using stents and coils is technically feasible. The stent maintains patency of the parent artery while allowing strategic coil placement in the aneurysm sac away from the origin of side branches. This technique may prove useful in the future treatment of intracranial fusiform aneurysms. However, potential sources of technical difficulties have been identified, and further longterm studies using an appropriate intracranial stent will be necessary before human application.
