Modern cerebrovascular bypass surgery uses either extracranial-intracranial (EC-IC) or intracranial-intracranial (IC-IC) approaches. Compared with EC-IC bypasses, IC-IC bypasses allow neurosurgeons to safely address tumors, aneurysms, and other lesions using shorter grafts that are well matched to the size of recipient vessels. Fewer than 100 articles have been published on IC-IC bypasses compared with more than 1000 on EC-IC bypasses. This study examined the increase of interest and innovation in IC-IC bypass.
PubMed and Web of Science were searched using keywords specific to IC-IC bypass, yielding 717 articles supplemented with 36 reports from other databases and gray literature. The articles were reviewed, and 98 articles were selected for further evaluation. Final articles were categorized as innovations or retrospective studies. Publication metrics were passed through an analytic program to assess statistical measures of growth.
The number of publications describing innovations (n = 52) and retrospective studies (n = 46) in IC-IC surgical techniques increased exponentially (R = 0.983 and R = 0.993, respectively), with both interest and research in the field increasing. The rate of publications in each group also increased. In recent years, increasing numbers of global institutions have researched and published on IC-IC bypasses.
As more work is undertaken on IC-IC bypasses, it is critical for knowledge to be shared through research, collaboration, publication, and early teaching within residency training programs. This field has increased exponentially in the past 2 decades and has yet to reach an inflection point, indicating possible additional interest and growth over time.
现代脑血管搭桥手术采用颅外-颅内（EC-IC）或颅内-颅内（IC-IC）方法。与 EC-IC 旁路相比，IC-IC 旁路使神经外科医生能够使用与受体血管尺寸匹配良好的更短移植物安全地处理肿瘤、动脉瘤和其他病变。与超过 1000 篇关于 EC-IC 旁路的文章相比，关于 IC-IC 旁路的文章发表不到 100 篇。本研究检查了 IC-IC 旁路的兴趣和创新的增加。
使用特定于 IC-IC 旁路的关键字在 PubMed 和 Web of Science 上进行搜索，得到 717 篇文章，并辅以其他数据库和灰色文献中的 36 份报告。对这些文章进行了回顾，选择了 98 篇文章进行进一步评估。最终的文章被归类为创新或回顾性研究。通过分析程序传递出版指标，以评估增长的统计衡量标准。
描述 IC-IC 手术技术创新（n=52）和回顾性研究（n=46）的出版物数量呈指数增长（R=0.983 和 R=0.993），该领域的兴趣和研究均有所增加。每组的出版物数量也在增加。近年来，越来越多的全球机构对 IC-IC 旁路进行了研究和发表。
随着对 IC-IC 旁路的研究不断增加，通过研究、协作、出版以及住院医师培训计划中的早期教学来共享知识至关重要。该领域在过去 20 年中呈指数增长，尚未达到拐点，这表明随着时间的推移可能会有更多的兴趣和增长。
