Stenting for systematic Intracranial artery stenosis is challenged recently, especially for safety. This registry is aimed to explore the safety profile during peri-operation period in Stenting procedures for systematic Intracranial artery stenosis in Chinese population in real world.

Systematic Intracranial Artery Stenosis

Study Type: Observational [Patient Registry]
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Target Follow-Up Duration: 12 Months
Official Title: Stenting for Symtomatic Intracranial Artery Stenosis Registry in China

Further study details as provided by Beijing Tiantan Hospital:

Primary Outcome Measures:
  • Safety during peri-operation period [ Time Frame: 30 days after operation ]
    Stroke in target cerebral vessel or death within 30 days after stenting procedure for systematic Intracranial artery stenosis

Secondary Outcome Measures:
  • Recurrent stroke in 30days to 1 year after stenting in target vessel area. [ Time Frame: 30days to 1 year after stenting ]
    Recurrent stroke in 30days to 1 year after stenting in target vessel area.

  • Successful recanalization rate right after stenting [ Time Frame: right after stenting ]
  • Stent restenosis rate [ Time Frame: Within 1 year after stenting ]
  • Ischemic stroke outside target vessel area [ Time Frame: 30 days - 1 year after stenting ]
  • Cerebral haemorrhage [ Time Frame: 30 days - 1year after ]
  • Myocardial infarction [ Time Frame: within 1 year ]
  • non-stroke haemorrhage [ Time Frame: within 1year ]
  • Death in 30 days- 1 year after stenting [ Time Frame: 30 days- 1 year after stenting ]
  • disabled stroke [ Time Frame: within 1year ]
  • Any stroke or death [ Time Frame: within 1 year ]
  • Serious adverse event [ Time Frame: within 1year ]
  • National Institutes of Health Stroke Scale score(NIHSS score) [ Time Frame: at 30 days and 1 year after stenting ]
  • Modified Rankin score(mRS) [ Time Frame: at 30 days and 1 year after stenting ]
  • MoCA scale score [ Time Frame: at 30 days and 1 year after stenting ]
  • Life quality scale score [ Time Frame: at 1 year after stenting ]

Study Population
patients with systematic Intracranial artery stenosis for stenting procedure

Inclusion Criteria:

  • medical failure patient with systematic Intracranial artery stenosis
  • More than 3 weeks after most recent ischemic stroke
  • Digital Subtraction Angiography(DSA) showed ≥70% stenosis in target intracranial artery

  • Intracranial tumor, arterial aneurysm or intracranial arteriovenous malformation

    •>50% stenosis in extracranial carotid artery or vertebral artery in operation side; Known contradiction to heparin, aspirin, clopidogrel, anesthesia or contrast; hemoglobin <10g/dl,platelet count <100000

  • Modified Rankin score ≥3 related to target vessel;
  • INR(International Normalized Ratio)>1.5(irreversible),persist hemorrhage risk; life expectancy < 1year
  • Pregnant or beast-feeding
  • Not suitable for endovascular stenting judged by Indication Judgement Committee
