BACKGROUND Application of direct aspiration catheters has revolutionized acute stroke care and has led to significant improvement in clinical outcome with a good safety profile. Catheter fracture and retention is a rare but potentially devastating complication. CASE DESCRIPTION Here we present two cases of acute stroke complicated by aspiration catheter fracture and retention. Successful catheter retrieval and revascularization was achieved in both cases. The stenosis or tortuosity of vascular anatomy appears to be the probable contributor to catheter breakage by anchoring the catheter with resultant fracture at the constraint point from catheter withdrawal tensile stress. CONCLUSION This report describes application of snare devices in retrieving a broken catheter during thrombectomy in the anterior and posterior circulation, and therefore presents a technique that can be safely utilized to address catheter breakage complicating thrombectomy in different vascular anatomic locations.

神经血栓切除术中的直接抽吸导管断裂和取出。

背景技术直接抽吸导管的应用彻底改变了急性中风护理，并导致临床结果的显着改善和良好的安全性。导管断裂和保留是一种罕见但可能具有破坏性的并发症。病例描述 在这里，我们介绍了两例急性中风并发抽吸导管断裂和滞留的病例。在这两种情况下都实现了成功的导管取出和血运重建。血管解剖结构的狭窄或曲折似乎是通过锚定导管导致导管断裂的可能原因，导致导管撤回拉伸应力在约束点处断裂。结
