To analyse the self-closing aneurysm clip historical evolution.
The authors reviewed the self-closing aneurysm clip's 50-year history. Major neurosurgical books, journals, testimonials, authors' personal experience, and scientific databases were analysed.
Self-closing aneurysm clip malfunction was found to be related to different clip strengths (too strong or too weak) and clip's corrosion or fracture due to diverse stainless steel biocompatibility issues. It was found that 301, 401, 402, 58, and 17-7 PH alloys were not suitable for human implantation due to high risk of corrosion. In counterpart, 316MOSS, Elgiloy, Phynox, and titanium alloys were more biocompatible and less prone to corrosion. The last group showed no motion on the magnetic field. Titanium clip has shown to be artifact free on computerized tomography followed by high-grade cobalt-chromium clip all the other aneurysms clip present a significant artifact. The Federal Drugs and Administration/American Society of Testing and Materials (FDA/ASTM) was a major contributor on safety development of self-closing aneurysm clip.
Our 36-year self-closing aneurysm clip experience is reported.
分析自动闭合动脉瘤夹的历史演变。
作者回顾了自动闭合动脉瘤夹50年的历史。分析了主要的神经外科学书籍、期刊、推荐材料、作者个人经验以及科学数据库。
发现自动闭合动脉瘤夹的故障与不同的夹力（过强或过弱）以及由于各种不锈钢生物相容性问题导致的夹子腐蚀或断裂有关。研究发现，301、401、402、58和17-7PH合金因腐蚀风险高而不适合人体植入。相比之下，316MOSS、埃尔吉洛伊耐蚀合金、菲诺克斯合金和钛合金具有更好的生物相容性，不易腐蚀。最后一组在磁场中无移动。钛夹在计算机断层扫描中显示无伪影，其次是高级钴铬夹，所有其他动脉瘤夹均存在明显伪影。美国食品药品监督管理局/美国材料与试验协会（FDA/ASTM）是自动闭合动脉瘤夹安全研发的主要贡献者。
报告了我们36年使用自动闭合动脉瘤夹的经验。
