Intracanial thrombus suction combined with visible thrombectomy stent for the treatment of acute intracranial main artery infarction: preliminary results of 5 cases / 介入放射学杂志

ABSTRACT

Objective To discuss the clinical effect of Penumbra aspiration system combined with Trevo thrombectomy device in treating acute intracranial main artery infarction.Methods The clinical data of a total of 5 patients with acute intracranial main artery infarction,who were treated with ACETM thrombectomy device combined with Trevo visible thrombectomy stent,were retrospectively analyzed.The lesions included anterior circulation infarction (n=2) and posterior circulation infarction (n=3).The mean age of patients was (60.4±11.6) years old.The operation time spent for thrombectomy,the recanalization time of occluded vessels,and the recovery of neural function were assessed.Results The puncture-recanalization intervals in the 5 patients were 29 min,32 min,35 min,33 min and 30 min respectively,with a mean time of (31.8±2.4) min.After intraoperative cerebral infarction thrombolysis treatment,the cerebral blood flow grading reached level 3.NIHSS score was remarkably improved from preoperative (11.0±7.4) points to 24 hpostoperative(4.2±1.1) points,to 7 days-postoperative(1.8±1.3) points,and to 30 days-postoperative (0.9±0.6) points (P＜0.05).Modified Rankin scale (mRS) score was 0-2 points in all patients.No intracranial hemorrhage transformation occurred.Conclusion In treating acute intracranial main artery infarction,ACETM thrombectomy device combined with Trevo visible thrombectomy stent can achieve the best recanalization effect with less times of thrombectomy procedure and short operation time.The clinical prognosis is satisfactory.
