Direct aspiration thrombectomy in treatment of middle cerebral artery M2 occlusion / 中国介入影像与治疗学

ABSTRACT

Objective: To investigate the effect of direct aspiration thrombectomy in treatment of middle cerebral artery M2 occlusion. Methods: Data of 8 patients with middle cerebral artery M2 occlusion who underwent direct aspiration thrombectomy were retrospectively analyzed. The vascular recanalization rate, intracranial hemorrhage 24 h after operation, National Institute of Health stroke scale (NIHSS) score before and 24 h, 14 days after thrombectomy, as well as the modified Rankin scale (mRS) score 90 days after thrombectomy were assessed. Results: Aafter thrombectomy, successful recanalization was obtained in all 8 cases, needing no other thrombectomy equipment nor technical remedies. No symptomatic intracranial hemorrhage occurred, while asymptomatic intracranial hemorrhage occurred in 3 patients. NIHSS scores gradually decreased 24 h and 14 days after operation. Ninety days after thrombectomy, good functional outcome with a mRS score ≤2 were achieved in all 8 patients, excellent functional outcome with a mRS score ≤1 was observed in 7 of them. Conclusion: Direct aspiration thrombectomy for middle cerebral artery M2 occlusion can improve neurological function of patients at an early stage with good efficacy and safety.
