Abstract:
Objective:To observe the efficacy and safety of mechanical thrombectomy with retrievable stent in patients with acute basilar artery occlusion (ABAO).Methods:Twenty-five patients with ABAO admitted to our hospital from December 2016 to October 2019 were chosen in our study. In patients who were eligible for intravenous thrombolysis and had onset within 4.5 h, mechanical thrombectomy with Solitaire AB stent was performed besides intravenous thrombolysis. In patients who had contraindications for intravenous thrombolysis or had onset within 4.5-24 h, mechanical thrombectomy with Solitaire AB stent or mechanical thrombectomy with Solitaire AB stent combined with balloon dilatation and stenting were performed. The prognoses of the patients were determined by modified Rankin scale (mRS) 90 d after surgery. The clinical data and efficacy of the patients were analyzed retrospectively, and the differences in clinical data and prognoses between patients with cardiogenic embolization and those with large artery atherosclerosis were compared.Results:Twenty-four patients had successful recanalization, and one failed. Follow-up for 90 d showed that 11 patients had good prognosis, 8 had poor prognosis, and 6 died. In patients with cardiogenic embolization, the occlusion sites were located in the upper segment of the basilar artery ( n=4) and the middle segment of the basilar artery ( n=10); in patients with large-artery atherosclerosis, occlusion sites were located in the middle segment of the basilar artery ( n=6) and the under segment of the basilar artery ( n=5); the distribution of basilar artery occlusion sites between patients with cardiogenic embolization and those with large artery atherosclerosis was statistically different ( P<0.05). The mRS scores 90 d after surgery showed no significant differences ( P>0.05). Conclusion:Mechanical thrombectomy with retrievable stent is safe and feasible for patients with ABAO, and the occlusion sites of the basilar artery in ABAO may indicate the etiology of occlusion.
