Abstract

Background: Coil embolization for cerebral aneurysms is an important technique and is not likely to be replaced in the foreseeable future. Recently, the Target Tetra detachable coil (TTDC) has become available, thereby raising expectations for a safer embolization in small aneurysms. Based on our experience, we report the behavioral characteristics and effective utilization of TTDCs.

Methods: We analyzed 28 patients who underwent surgery using the TTDC for intracranial aneurysms between December 2023 and November 2024.

Results: Five cases were treated using the TTDC only. In four of five cases, the aneurysm height was <3 mm. In terms of complications, intraprocedural rupture occurred in two cases and thrombosis in two. None of the patients presented with delayed hemorrhage during the follow-up period.

Conclusion: The TTDC coils cluster at the tip of the microcatheter. Thus, effective embolization can be achieved by filling from the deeper available space. Based on the behavioral characteristics of TTDCs, it is not only beneficial as a finishing coil but also plays a role in filling. We believe that TTDCs may be a useful option for embolizing small aneurysms, including ruptured ones that were previously challenging to treat, and cases in which microcatheter stability are compromised.

背景:脑动脉瘤线圈栓塞术是一项重要的技术,在可预见的未来不太可能被取代。最近,Target Tetra可拆卸线圈(TTDC)已经可用,从而提高了对小动脉瘤更安全栓塞的期望。根据我们的经验,我们报告了ttdc的行为特征和有效利用。方法:我们分析了2023年12月至2024年11月期间使用TTDC手术治疗颅内动脉瘤的28例患者。结果:5例患者仅使用TTDC治疗。结论:TTDC线圈聚集在微导管的尖端。因此,有效的栓塞可以通过从更深的可用空间填充来实现。根据ttdc的行为特点,它不仅可以作为整理线圈,还可以起到填充的作用。我们认为ttdc可能是栓塞小动脉瘤的有效选择,包括先前难以治疗的破裂动脉瘤,以及微导管稳定性受损的病例。
