Abstract:
Objective To investigate the effect of mechanical thrombectomy device Solitaire AB for the treatment of distal occlusion of the intracranial artery caused acute anterior circulation ischemic stroke. Methods The clinical data of 9 patients with arterial occlusion of distal anterior circulation treated by using the Solitaire AB thrombectomy device were analyzed retrospectively. Seven of them had M2 middle cerebral artery occlusion and 2 had A3 occlusion. Their clinical features,imaging data,treatment,and the results of 3-month clinical follow-up were analyzed. The effectiveness of treatment was evaluated through the recanalization rate after stent thrombectomy,the National Institutes of Health Stroke Scale (NIHSS)scores before and after treatment,the modified Rankin scale (mRS)scores,and the 3-month clinical follow-up results. The surgery-related complications and mortality of patients were used to evaluate the safety of the treatment. Results (1 )Of the 9 intracranial arterial occlusions,8 were recanalized successfully. The modified thrombolysis in cerebral infarction (mTICI)was 2b or grade 3. (2)The NIHSS score median 9. 5 (3. 0,15. 5)at discharge dropped significantly compared with 19. 0 (16. 0,22. 0)before procedure. (Z=2. 703,P=0. 007). No permanent complications related to operation occurred. Four of the recanalized patients had good prognosis (mRS 0-1)and 4 had disability (mRS 3-4 ). The mRS score of one non-recanalized patient was 4 at the 3 months follow-up. Conclusion The embolectomy effect is good whom using Solitaire AB device for acute occlusion occurred in the intracranial artery M2 or A3 segment. Its efficacy,safety,and indications still need to be further explored in a larger sample controlled trial.
