[Long-term outcome after endovascular treatment of high-risk patients with recurrently symptomatic intracranial stenoses of the posterior circulation].
We present long-term clinical and duplex data from high-risk patients with severe, recurrent symptomatic stenoses of the vertebrobasilar circulation. We hypothesized that despite the greater risk of periprocedural complications in this patient group, interventional treatment would reduce the risk of recurrent strokes relative to the expected natural risk. We also predicted that the long-term treatment outcome would be positively influenced by the use of stents and by the periprocedural technical success rate.
