The Impact

IntroductionThe safety outcomes of endovascular therapy for intracranial artery stenosis in a real-world stetting are largely unknown. The Clinical Registration Trial of Intracranial Stenting for Patients with Symptomatic Intracranial Artery Stenosis (CRTICAS) was a prospective, multicentre, real-world registry designed to assess these outcomes and the impact of centre experience.Methods1140 severe, symptomatic intracranial arterial stenosis (ICAS) patients treated with endovascular therapy were included from 26 centres, further divided into three groups according to the annual centre volume of intracranial angioplasty and stent placement procedures over 2 years: (1) high volume for ≥25 cases/year; (2) moderate volume for 10–25 cases/year and (3) low volume for <10 cases/year.ResultsThe rate of 30-day stroke, transient ischaemic attack or death was 9.7% (111), with 5.4%, 21.1% and 9.7% in high-volume, moderate-volume and low-volume centres, respectively (p<0.05). Multivariable logistic regression confirmed high-volume centres had a significantly lower primary endpoint compared with moderate-volume centres (OR=0.187, 95% CI: 0.056 to 0.627; p≤0.0001), while moderate-volume and low-volume centres showed no significant difference (p=0.8456).ConclusionCompared with the preceding randomised controlled trials, this real-world, prospective, multicentre registry shows a lower complication rate of endovascular treatment for symptomatic ICAS. Non-uniform utilisation in endovascular technology, institutional experience and patient selection in different volumes of centres may have an impact on overall safety of this treatment.

Surgical revascularization may be beneficial in patients with ischemic stroke caused by intracranial stenosis or occlusion who are ineligible for thrombolysis. Objective To evaluate the outcome of superficial temporal artery to middle cerebral artery (STA-MCA) bypass in ischemic stroke caused by intracranial artery stenosis or occlusion. Methods We retrospectively studied successive case series of 19 patients who underwent surgical treatment between 2013–2017 of STA-MCA bypass. Surgical procedure was performed for the patients with acute ischemic stroke who were ineligible for thrombolysis. Results Of the 19 patients enrolled, symptom aggravation occurred during medical treatment, the patients were ineligible for thrombolysis despite being within 8 hours of symptom onset. Bypass significantly improved National Institutes of Health Stroke Scale scores, mean patient age was 78.05 years (range, 39–78 y). However, male 11 (57.95%) out of nineteen patients were presented with left-sided-lesions while female 8 (42%) had right-sided lesions with significant infarction growth by diffusion weighted imaging achieved, after surgical maneuver. No major complications occurred intraoperatively, in contrast to 2 (10.5%) minor manifestation were suffering minor complications probably they included the remote infarction (posterior cerebral artery territory). Pooled analysis with our patients showed a significant neurological improvement and a good outcome in 13 (68.4%) patients without hemorrhage or any other complication, 6 (31.6%) patients with unfavorable outcome (severe disability 2; vegetative state 4, non of them are died 0;). Conclusion STA-MCA bypass may be beneficial to patients with acute stroke or stenosis in progress who are ineligible for medical therapy. Furthermore, it appears safe when the infarction is small. These findings indicate that STA-MCA bypass could be considered as a treatment option in selected patients with ischemic stroke caused by intracranial stenosis or occlusion.
