Parent and Child Balloon Technique for Navigating Guide Catheters During Neurointerventions

Area of Science:

• Interventional Neuroradiology
• Vascular Surgery
• Medical Device Technology

Background:

• Guide catheter stabilization is critical for successful neurointerventional procedures.
• Challenging vascular anatomies, including severe atherosclerosis and bovine arch, pose significant navigation difficulties.
• Existing techniques may lack the necessary stability for complex cases.

Purpose of the Study:

• To present and evaluate a novel technique for navigating guide catheters using a parent and child balloon system.
• To demonstrate the utility of this technique in patients with complex vascular anatomies.
• To assess the safety and efficacy of the parent and child balloon technique.

Main Methods:

• The study involved 9 patients with severe atherosclerosis or anomalous aortic arches.
• 8-9-F balloon-mounted guide catheters were employed, navigated using balloon-attached guidewires.
• Parent and child balloons were utilized complementarily for flow navigation and vessel fixation.

Main Results:

• Successful insertion of the balloon guide catheter to the target positions was achieved in all cases.
• Neurointerventional procedures were completed without any reported complications.
• The technique proved effective in managing challenging vascular anatomies.

Conclusions:

• The parent and child balloon technique offers a valuable solution for guide catheter insertion in difficult vascular anatomies.
• This method enhances procedural safety and success rates in neurointerventions.
• The complementary use of balloons provides effective vessel fixation and navigation support.
