ABSTRACT
BACKGROUND:
The safety and effectiveness of stent retriever use for patients with acute large vessel occlusion (LVO) due to intracranial atherosclerotic disease (ICAD) is not well established. We investigated the differences in clinical outcomes in patients with and without ICAD.METHODS:
We analyzed the Japan Trevo Registry, a nationwide registry which enrolled patients with acute LVO who underwent endovascular therapy (EVT) using the Trevo retriever alone or in combination with an aspiration catheter. We compared the technical and clinical outcomes of EVT between the ICAD and No-ICAD groups. The primary outcome was effective reperfusion and the secondary outcome was modified Rankin scale (mRS) score 0-2 at 90 days. Safety outcomes were worsening of neurologic symptoms within 24 hours, any intracranial hemorrhage within 24 hours, vessel dissection/vessel perforation related to using the Trevo retriever and mortality at 90 days.RESULTS:
A total of 835 patients (45 in the ICAD group and 790 in the No-ICAD group) were analyzed. In the ICAD group, more men (68.9% vs 50.8%, P=0.02) and a lower median National Institutes of Health Stroke Scale score at admission (11 vs 18, P<0.0001) were observed. The primary outcome was significantly more common in the No-ICAD group (92.5%) than in the ICAD group (80.0%) (adjusted odds ratio (aOR) 0.21, 95% CI 0.09 to 0.50). The proportion of patients with mRS score 0-2 at 90 days was significantly lower in the ICAD group (44.4% vs 42.4%, aOR 0.49, 95% CI 0.23 to 1.00, P=0.0496). Other secondary and safety outcomes were not significantly different between the two groups.CONCLUSIONS:
Patients with LVO with ICAD had a lower rate of effective reperfusion than those with No-ICAD.
