Area of Science:

  • Vascular Surgery
  • Microsurgery
  • Biomedical Engineering

Background:

  • Microvascular coupling systems aid small vessel anastomosis.
  • Current methods face challenges, particularly in securing vascular walls.
  • Difficulties in pinning can impede procedure efficiency and safety.

Purpose of the Study:

  • To introduce a novel "push down" technique for microvascular anastomosis.
  • To present newly-designed micro-forceps to overcome pinning difficulties.
  • To evaluate the effectiveness and safety of this technique in clinical venous couplings.

Main Methods:

  • Development of a "push down" technique.
  • Design and utilization of specialized micro-forceps.
  • Application in 111 venous couplings (96 anastomoses).

Main Results:

  • Successful application of the "push down" technique and micro-forceps.
  • Demonstrated effectiveness and safety in clinical settings.
  • Positive patency results reported for the anastomoses.

Conclusions:

  • The "push down" technique with micro-forceps is effective for microvascular coupling.
  • This approach enhances safety and efficiency in small vessel anastomosis.
  • The findings support the clinical utility of this improved microvascular system.
