Özet

Introduction Endovascular treatment (ET) is a beneficial treatment for M1-2 occlusions of the middle cerebral artery. Mortality and disability rates are high if large vessel occlusions are not treated. While these rates are lower in M3 occlusions, important branch blockages can lead to disability. Endovascular treatment of small vessel occlusions is difficult, and there are no studies on the effectiveness of endovascular treatment for M3 occlusions. Accordingly, in this study, our aim was to assess the feasibility, safety, and preliminary efficacy of endovascular therapy for M3 occlusions. Methods This study involved a retrospective analysis of a prospectively collected from two centres for acute ischemic stroke of the anterior system between July 2015 and April 2020. Demographic, radiologic, procedural and outcome variables were collected for patients who underwent endovascular therapy for acute ischemic stroke of the anterior system. Results Complete or near complete reperfusion (mTICI 2b-3) of the M3 occlusion was achieved in 15 cases (38.5%). Complete (mTICI 3) reperfusion was achieved in 24 cases (61.5%). Twenty-six patients were treated for primary M3 occlusion, while 13 patients with M3 occlusion were treated as a rescue strategy after successful treatment of a proximal greater vascular occlusion. Complete or near complete reperfusion (mTICI 2b-3) of primary occlusion was achieved in eight cases (30.8%), and complete (mTICI 3) reperfusion was achieved in 18 cases (69.2%). In addition, complete or near complete reperfusion (mTICI 2b-3) of rescue M3 occlusion was achieved in seven cases (%53.8), while complete (mTICI 3) reperfusion was achieved in six cases (46.2%). Only one patient with primary M3 occlusion had ICH due to extravasation. The patient's neurological examination one month later was normal. Conclusions This retrospective study demonstrates that endovascular treatment of M3 occlusions is safe, effective and reliable.
