| Summary: | INTRODUCTION: Large vessel occlusion can present with minor stroke in 30% of cases. Although the efficacy of mechanical thrombectomy in minor stroke National Institute of Health Stroke Scale (NIHSS<6) has been shown in subgroups of clinical trials, there is no randomized clinical trial focusing on this patient group.
METHODS: 8 patients (3 female, 5 male) presenting with minor stroke (NIHSS<6) with large vessel occlusion on CT angiography were included. Thrombolytic treatment was administered in 5 patients presenting in 4.5 hours. Mechanical thrombectomy was performed within 6 hours in 5 patients and in 3 patients presenting beyond 6 hours. Modified treatment in cerebral ischemia (mTICI) 2b-3 was considered as successful recanalzation, functional outcome was evaluated at 90 day.
RESULTS: 8 patients with ages between 40 and 81 years were included in the study. Successful recanalization (mTICI 2b-3) was achieved in all cases. 3 patients were not eligible for intravenous thrombolysis due to late arrival time. In these cases, after clinical deterioration occured mechanical thrombectomy was performed. 90 day mRS were 2, 4 and 5 in these 3 cases. 90 day modified Rankin Scale (mRS) were between 0-2 in all 5 patients treated within 6 hours.
DISCUSSION AND CONCLUSION: Although there are few cases, our study demonstrated that mechanical thrombectomy is more efficaceous in minor stroke patients when performed earl, as demonstrated in other studies.
