Area of Science:

  • Interventional Neuroradiology
  • Vascular Surgery
  • Medical Device Technology

Background:

  • Balloon-assisted coiling (BAC) is a common endovascular technique for treating intracranial aneurysms.
  • Current BAC procedures often require larger guiding catheters or a bifemoral approach, potentially increasing procedural complexity and patient trauma.
  • The development of specialized guiding catheters aims to optimize access and manipulation of multiple devices during complex endovascular interventions.

Purpose of the Study:

  • To evaluate the utility and safety of the new 6F Envoy guiding catheter with an enlarged inner diameter for dual microcatheter access in balloon-assisted coiling (BAC).
  • To assess the feasibility of using this guiding catheter as an alternative to larger (7F) guiding catheters or the bifemoral approach in BAC procedures.
  • To determine if this approach simplifies the procedure and reduces vessel wall trauma.

Main Methods:

  • Retrospective analysis of 48 patients undergoing BAC procedures using the 6F Envoy guiding catheter.
  • Simultaneous insertion and manipulation of a 0.014-inch microcatheter and a balloon microcatheter through the guiding catheter.
  • Assessment of procedural ease, angiographic quality, and technical success.

Main Results:

  • The 6F Envoy guiding catheter successfully accommodated both microcatheters, facilitating easy manipulation.
  • High-quality control angiograms were obtained throughout the procedures.
  • The use of the 6F Envoy guiding catheter eliminated the need for larger 7F catheters or the bifemoral approach in indicated cases.
  • The procedure was technically simpler for the operator and less traumatic to the vessel wall.

Conclusions:

  • The 6F Envoy guiding catheter with its enlarged inner diameter is a safe and effective tool for dual microcatheter access in balloon-assisted coiling.
  • This guiding catheter simplifies BAC procedures, offering a less traumatic alternative to conventional methods.
  • Its use can potentially reduce procedural time and improve patient outcomes in the treatment of intracranial aneurysms.
