Application of Penumbra retrograde semi-retrieval Solitaire stents technique in mechanical thrombectomy in patients with acute basilar artery occlusion / 中国医师进修杂志

ABSTRACT

Objective:To explore the curative effect of Penumbra retrograde semi-retrieval Solitaire stents technique in the treatment of acute basilar artery occlusion.Methods:The clinical data of 15 patients with acute basilar artery occlusion in Shengjing Hospital of China Medical University from January 2017 to December 2019 were analyzed retrospectively. All patients were treated with Penumbra retrograde semi-retrieval Solitaire stents technique. The modified thrombolysis in cerebral infarction (mTICI) was used to evaluate the therapeutic effect.Results:Fifteen patients achieved vascular recanalization of occluded basilar artery, and mTICI 2b grade was in 3 cases, 3 grade in 12 cases. One operation completed vascular recanalization in 11 cases, 2 times in 3 cases,3 times in 1 case. CT images 24 to 48 h after operative showed no intracranial hemorrhage. The National Institutes of Health stroke scale (NIHSS) score at discharge was significantly lower than that before surgery (4.8 ± 2.1) scores vs. (16.1 ± 5.7) scores, and there was statistical difference ( P<0.01). Conclusions:Penumbra retrograde semi-retrieval Solitaire stents technique can improve the efficiency of thrombus grasping and significantly improve patient symptoms.
