Area of Science:

  • Neuroendovascular surgery
  • Medical device training
  • Aneurysm treatment

Background:

  • The WEB Intra-saccular Therapy (WEB-IT) trial evaluated the WEB device for wide-neck bifurcation aneurysms.
  • A neurovascular replicator was utilized to simulate patient-specific anatomy and hemodynamics for device implantation training.

Purpose of the Study:

  • To assess a unique neurovascular replicator-based training program's impact on technical performance and patient safety within the WEB-IT study.
  • To optimize physician proficiency with the WEB device prior to patient treatment.

Main Methods:

  • US investigators underwent a comprehensive training program involving full surgical rehearsals on a neurovascular replicator.
  • Patient-specific anatomical replicas were used for pre-procedural rehearsals, with no roll-in cases permitted.
  • Training included centralized and on-site sessions, emphasizing hands-on experience before patient procedures.

Main Results:

  • 48 investigators across 25 US centers utilized the replicator training program.
  • Fluoroscopy and procedure times were comparable to European trials with experienced physicians.
  • The training program facilitated the introduction of a new technology without compromising procedural efficiency.

Conclusions:

  • A neurovascular-replicator-based training program was successfully implemented in the WEB-IT study.
  • This novel training methodology demonstrated potential for optimizing technical success and patient safety.
  • The program offers a new approach to physician education for emerging neurovascular technologies.
