Clip-knotting technique for intracranial arterial suturing through deep and narrow surgical corridors—how I do it

  • Jaechan ParkEmail author
How I Do it - Vascular



One of the most difficult procedures through a deep and narrow surgical corridor is tying a knot following microsuturing, even though microvascular suturing is a fundamental technique for neurovascular surgeons.


A novel technique replacing the conventional knot-tying method was devised. The proposed clip-knotting technique uses an aneurysm clip to hold both remaining ends of a thread that is sutured in a running manner.


The proposed clip-knotting technique can facilitate the microsuturing procedure for intracranial arterial repair in a deep and narrow operative field.
