Area of Science:

  • Microsurgery
  • Vascular Anastomosis
  • Reconstructive Surgery

Background:

  • Anastomotic obstructions are major complications in free flap surgery.
  • Mechanical couplers offer improved venous patency and reduced operating time compared to sutures.
  • Initial experience with a novel coupler for venous anastomosis in free flap surgery is presented.

Purpose of the Study:

  • To evaluate the initial experience and efficacy of a mechanical coupler for venous anastomosis in free flap surgery.
  • To assess complication rates and functional outcomes associated with coupler use.

Main Methods:

  • Retrospective study of 10 patients (11 flaps) undergoing free flap reconstruction using a mechanical coupler for end-to-end venous anastomosis.
  • Flaps were used for cervico-facial defects, limb defects, and other reconstructive needs.
  • Various flap types and coupler sizes (2.5, 3, and 3.5 mm) were employed.

Main Results:

  • No venous complications were observed in the study cohort.
  • One flap failure occurred due to arterial ischemia, not venous anastomosis issues.
  • The coupler facilitated 15 venous anastomoses with no instances of obstruction.

Conclusions:

  • The mechanical coupler is a safe and effective alternative to sutures for venous anastomosis in free flap surgery.
  • This technique demonstrates reliability for both head and neck and limb reconstructions.
  • The coupler provides a fast and dependable option, potentially improving surgical outcomes.
