Brief summary
In acute ischemic stroke caused by intracranial large vessel occlusion, rescue intracranial stenting has been recently a treatment option to achieve recanalization in patients with the failure of mechanical thrombectomy. Nevertheless, there are few studies supporting this beneficial treatment in two cerebral circulations. We aimed to analyse whether the use of rescue intracranial stenting would improve prognosis of patients at 3 months.
Detailed description
In Asia population, large intracranial arterial stenosis lesion accounts for more than 30% in common causes of ischemic stroke, compares with about 10% in Caucasian population every year. Normally, in human brain, there are about 130 billion neurons but they are lost equivalent to their losses in approximately 3.6 years of normal aging in case of a large vessel ischemic stroke untreated each hour. Consequently, after the success of 5 randomized controlled trials about the mechanical thrombectomy, which have been done from December 2010 to December 2014, all of guidelines recommended this technique as the first-line treatment in acute ischemic stroke. However, the HERMES meta-analysis showed that revascularisation failure ratio 28.9% in patients older than 80 years. Recently, in case of mechanical thrombectomy failure, many studies suggested the rescue intracranial stenting could be alternative urgently needed treatment to achieve permanent recanalization which is one of the most important factors impacting on clinical outcomes after acute ischemic stroke. Hence, the aims of our study were to assess both the non-poor outcome at 3 months and the symptomatic intracerebral hemorrhage relating to procedure in patients receiving rescue intracranial stenting.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| The non-poor 3-month outcome rate. | 3 months | The non-poor 3-month outcome rate was accessed by modified Rankin Score (mRS), which comprised of included good (mRS 0 - ≤ 2) and fair (mRS 3). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| The symptomatic intracerebral hemorrhage rate. | 24 hours after rescue intracranial stenting. | The symptomatic intracerebral hemorrhage was defined as patient's intracerebral hemorrhage with postprocedural mRS ≥ 5 and there were no other evident causes for the increased mRS. |
