摘要

Purpose: Retrievable stents are widely used in acute ischemic stroke(AIS);however, the results remain unclear in Chinese patients. This study aimed to explore the usefulness of Solitaire AB stents in AIS. Materials and Methods: Seventy-three AIS patients treated with Solitaire AB stents for thrombectomy of large artery occlusion of anterior circulation in January 2014-June 2015 were retrospectively evaluated. Recanalization was assessed with the Thrombolysis In Cerebral Ischemia(TICI) scale. Clinical outcomes were assessed according to the National Institute of Health Stroke Scale(NIHSS) and the modified Rankin Scale(mRS). Operation-related complications were recorded. The main factors affecting successful recanalization with Solitaire AB were analyzed. Results: The 73 patients enrolled included 39 males and 34 females(median age of 59 [31-78] years);77 Solitaire AB stents were used. The initial recanalization rate with Solitaire AB as the first thrombectomy method was 53.42%(39/73;recanalization group). Among the 34 patients with failed stent retrieval, 32 underwent other treatments;the final arterial recanalization rate was 89.04%(65/73). Perioperative embolization events and symptomatic intracranial hemorrhage(sICH) occurred in 5 and 8 patients, respectively. The mean NIHSS score was 9.12±3.86 one week after thrombectomy, significantly lower compared with admission values. In 31 patients(42.47%), NIHSS score decreased by >8. Good functional independence(mRS score≤2) was achieved in 39 patients(53.42%) at 90 days;12 patients(16.44%) died. Compared with the recanalization group, the remaining patients showed lower AF and higher LAA percentages. Conclusion: Solitaire AB stents are useful in the endovascular treatment of AIS.
