Mechanical embolectomy with the Solitaire AB device after acute basilar artery thrombosis: A report of 6 cases / 中国脑血管病杂志

ABSTRACT

Objective: To evaluate the efficacy and safety of arterial embolectomy with the Solitaire AB stent after acute basilar artery thrombosis. Methods: Six patients performed arterial embolectomy with the Solitaire AB stent after acute basilar artery thrombosis in the Encephalopathy Center, Guangdong Province Hospital of Traditional Chinese Medicine from May to November 2010 were analyzed retrospectively. Stent angioplasty was performed for patients with residual stenosis ≥50%. Their immediate effect of thrombectomy and postoperative bleeding were analyzed. The National Institutes of Health Stroke Scale (NIHSS) scores and the prognosis were compared before and after the treatment. Results: Circled digit oneAfter 1 to 2 embolectomies, the basilar arteries of the 6 patients were revascularized, in 5 patients with residual stenosis were treated in combination with balloon angioplasty and stenting. Circled digit twoOne patient had acute in-stent thrombosis after the release of stent. The angioplasty re-examination showed that the basilar artery was patent after the treatment. Circled digit three5 patients were re-examined by MRI 3 to 7 days after procedure. There were no significant expansion of cerebral infarction, and their basilar arteries were patent. One patient had cerebral hemorrhage 1 day after procedure, and he died after 7 days. Circled digit fourThe NIHSS scores were lowered 2-15 at dischange than at admission in 5 patients. The modified Rankin Scale (mRS) scores in 5 patients were 0(1 patient), 1(2 patients) , and 2(2 patients) at discharge. Conclusion: Using Solitaire AB stent and embolectomy are relatively safe and effective in patients with acute basilar artery thrombosis, and the prognosis of patients is good.
