The Solitaire Platinum 4×40 mm stent retriever contains radiopaque markers with a long length. We evaluated the effect of Solitaire Platinum 4×40 mm stent retriever in Solumbra technique thrombectomy, and compared it with shorter Solitaire stent retrievers.
A total of 70 patients who underwent Solumbra technique thrombectomy with equal diameter (4 mm) and different length (40 vs. 20 mm) Solitaire stent retrievers were divided into two groups : the Solitaire Platinum 4×40 mm stent (4×40) group and the Solitaire FR 4×20 mm stent or Solitaire Platinum 4×20 mm stent (4×20) group. The clinical outcomes, Thrombolysis in Cerebral Infarction score, the first pass reperfusion status, and complications were evaluated and compared between the two groups. Multivariate analysis was performed to evaluate the predictive factors for reperfusion and complete reperfusion from the first pass.
Higher first-pass reperfusion and complete reperfusion were achieved in the 4×40 group (68.0% and 48.0%) than in the 4×20 group (46.7% and 33.3%; p=0.004 and 0.007, respectively). In multivariate analysis, radiopaque device and longer stent retriever were correlated with first-pass reperfusion (p=0.014 and 0.008, respectively) and first-pass complete reperfusion (p=0.022 and 0.012, respectively).
Our study demonstrated the usefulness of the Solitaire Platinum 4×40 mm stent retriever, which led to higher firstpass reperfusion and complete reperfusion rates than the Solitaire FR 4×20 mm stent or the Solitaire Platinum 4×20 mm stent, especially in Solumbra technique thrombectomy.
Solitaire Platinum 4×40 mm支架取栓器含有不透射线的标记物且长度较长。我们评估了Solitaire Platinum 4×40 mm支架取栓器在Solumbra技术血栓清除术中的效果，并将其与较短的Solitaire支架取栓器进行比较。
共有70例接受Solumbra技术血栓清除术的患者，使用直径相同（4 mm）但长度不同（40 vs. 20 mm）的Solitaire支架取栓器，分为两组：Solitaire Platinum 4×40 mm支架（4×40）组和Solitaire FR 4×20 mm支架或Solitaire Platinum 4×20 mm支架（4×20）组。评估并比较两组的临床结局、脑梗死溶栓评分、首次通过再灌注状态及并发症。进行多变量分析以评估首次通过时再灌注和完全再灌注的预测因素。
4×40组的首次通过再灌注率和完全再灌注率（分别为68.0%和48.0%）高于4×20组（分别为46.7%和33.3%；p分别为0.004和0.007）。在多变量分析中，不透射线装置和较长的支架取栓器与首次通过再灌注（分别为p = 0.014和0.008）及首次通过完全再灌注（分别为p = 0.022和0.012）相关。
我们的研究证明了Solitaire Platinum 4×40 mm支架取栓器的有效性，其首次通过再灌注率和完全再灌注率高于Solitaire FR 4×20 mm支架或Solitaire Platinum 4×20 mm支架，尤其是在Solumbra技术血栓清除术中。
