Area of Science:

  • Microsurgery
  • Vascular Surgery
  • Transplantation

Background:

  • Microvascular anastomosis is crucial for successful free flap transplantation.
  • Vessel size mismatch is a significant challenge in micro-anastomosis, potentially leading to thrombosis and flap failure.
  • Maintaining optimal blood flow and minimizing endothelial disruption are key goals.

Purpose of the Study:

  • To present a simple and effective technique for managing vessel size mismatch during microvascular anastomosis.
  • To introduce a customizable longitudinal arteriotomy method for achieving adequate vessel size matching.
  • To report on the long-term efficacy of this technique in clinical practice.

Main Methods:

  • A single, customizable longitudinal arteriotomy is performed on the smaller vessel.
  • This technique facilitates end-to-end anastomosis by creating an adequate size match with the larger vessel.
  • The method has been utilized for over 10 years in clinical practice.

Main Results:

  • The longitudinal arteriotomy technique effectively addresses vessel size mismatch.
  • This approach has consistently achieved patent end-to-end anastomosis.
  • The technique has demonstrated high patency rates in experienced hands.

Conclusions:

  • Vertical arteriotomy is a straightforward and reliable technique for microvascular anastomosis.
  • The method successfully overcomes vessel size discrepancies, leading to high patency rates.
  • This approach has proven effective over a decade of clinical application.
