The "Needle-splint" Technique: A Method of Accurate Apposition and Eversion during Microvascular Anastomosis

Area of Science:

• Microsurgery
• Vascular Surgery
• Surgical Techniques

Background:

• Microvascular anastomosis requires precise suturing for successful outcomes.
• Current microsurgical suturing techniques can be challenging for achieving optimal vessel apposition and eversion.
• Minimizing errors and enhancing visualization are critical in microsurgical procedures.

Purpose of the Study:

• To introduce and describe the novel "needle-splint" technique for microsurgical suturing.
• To demonstrate the versatility and benefits of the needle-splint technique in various microsurgical suturing methods.
• To highlight the technique's role in improving precision, visualization, and error reduction in microvascular anastomosis.

Main Methods:

• The "needle-splint" technique involves using the needle's curvature as a "pusher" during suturing.
• This technique facilitates finer apposition and eversion of vessel walls.
• Applicable to simple interrupted, continuous-interrupted, and multi-loops microsurgical suturing.

Main Results:

• The needle-splint technique enhances the overall micro-suturing process.
• It ensures finer apposition and vessel wall eversion during suture placement.
• The technique allows direct visualization of intra-wall-edges and intimal suture surfaces.
• It acts as a safety stabilizer, optimizing vessel alignment and aiding knot tying.

Conclusions:

• The needle-splint technique is a valuable advancement in microsurgical suturing.
• It improves accuracy, visualization, and safety in microvascular anastomosis.
• This technique offers enhanced control and precision for surgeons performing microvascular procedures.
