"A call for more public investment in cerebrovascular disease research to improve patient outcomes and advance scientific understanding."


The field of neurointerventional surgery has undergone a remarkable transformation, particularly since the advent of detachable coils. Technological advancements in medical devices and imaging have led to significant improvements in the clinical outcomes for patients with cerebrovascular diseases. Groundbreaking trials involving mechanical thrombectomy in stroke treatment stand as a testament to these advancements, showcasing impressive treatment effects.

While much of the progress in this area has been propelled by private sector funding, the initial seeds of innovation often stem from publicly funded projects. The first publication on modern stent-retriever thrombectomy, for instance, emerged from a project supported by the National Institute of Biomedical Imaging and Bioengineering. This highlights the crucial role of public investment in fostering fundamental research and innovation.

The success of neurointerventional surgery is largely attributed to collaborations between physician-scientists and industry, working together to develop minimally invasive techniques and devices for treating cerebrovascular diseases. However, with the increasing impact of stroke on healthcare systems and the proven benefits of intra-arterial intervention, there is a compelling need for greater public support to advance scientific understanding in this field.

The Underserved Area: Hypothesis-Driven Research

Although the development of devices and imaging technologies is flourishing through industry and academic partnerships, one area remains critically underserved: hypothesis-driven research. This type of research is essential for interrogating the underlying pathogenesis of cerebrovascular disease and understanding the healing response to interventional treatments. It delves deeper into the biological mechanisms at play, paving the way for more targeted and effective therapies.

One example of successful collaborative research comes from the field of fluid mechanics. Researchers solved the wall shear stress debate for atherogenesis of the carotid artery by using a team science approach. This involved vascular surgeons, vascular pathologists, and engineers working together to comprehensively study the issue. They conclusively linked low oscillatory wall shear stress with the formation of carotid plaques, demonstrating the power of interdisciplinary collaboration.

  • Encourage Interdisciplinary Collaboration: Bringing together scientists and engineers from diverse fields to tackle cerebrovascular disease.
  • Support Hypothesis-Driven Research: Increasing public funding for projects that investigate the underlying mechanisms of cerebrovascular disease.
  • Embrace Team Science: Recognizing the value of collaborative efforts between physicians, scientists, and industry.
The Society of Neurointerventional Surgery (SNIS) and its journal, JNIS, play a vital role in fostering collaboration and disseminating research related to interventional treatment of cerebrovascular disease. While interactions with physician-scientists within the SNIS reveal a strong appetite for team science, the reality is that physicians often have limited time for research. This underscores the necessity of engaging well-trained scientists to augment research efforts and achieve an equitable distribution of resources.

Embracing Knowledge and Truth

In a time when knowledge and truth are under attack, it is more important than ever to embrace science. From debates about evolution to climate change, facts are often discarded for personal beliefs and political expediency. Science, along with art, represents humanity's quest for truth, and is essential for our survival and progress. Those who have chosen the field of neurointervention, from scientists and engineers to physicians, are dedicated to helping patients suffering from life-altering cerebrovascular diseases. The goal is to disseminate the best science in the field of neurointervention and pursue knowledge to improve patient care.

Everything You Need To Know

1

How has neurointerventional surgery evolved to improve outcomes for cerebrovascular disease patients?

Neurointerventional surgery has dramatically changed thanks to detachable coils and progress in medical devices and imaging. Clinical outcomes for patients with cerebrovascular diseases have improved as a result of these advances. Notably, mechanical thrombectomy has demonstrated significant treatment benefits in stroke treatment.

2

What is the importance of public funding in advancing neurointerventional surgery?

While private funding has been instrumental, public investment plays a crucial role in early innovation. The first publication on modern stent-retriever thrombectomy, which emerged from a National Institute of Biomedical Imaging and Bioengineering project, exemplifies this. Public funding is critical for fostering fundamental research.

3

Why is hypothesis-driven research so critical in cerebrovascular disease, and how does it differ from device development?

Hypothesis-driven research is essential for understanding the underlying causes of cerebrovascular disease and the body's response to interventional treatments. Unlike device development, which is well-supported by industry, this area seeks to understand biological mechanisms for more targeted therapies. Collaborative research, like solving the wall shear stress debate for atherogenesis, demonstrates the power of this approach.

4

What role do organizations like the Society of Neurointerventional Surgery (SNIS) play in advancing the field, and what challenges do they face?

The Society of Neurointerventional Surgery (SNIS) and its journal, JNIS, foster collaboration and research dissemination. Physician-scientists within SNIS are eager for team science; however, physicians often lack time for research. Engaging well-trained scientists is necessary to augment research efforts and ensure equitable resource distribution.

5

What is the overarching goal of professionals in neurointervention, and why is it especially important today?

Those in neurointervention, including scientists, engineers, and physicians, are dedicated to helping patients with cerebrovascular diseases. They aim to disseminate the best science and pursue knowledge to improve patient care. This is crucial in a time when facts are often disregarded.
