Internal mammary perforators, branches of the internal mammary artery and vein, are suitable recipient vessels for breast microvascular reconstruction. Measurements confirm adequate diameter for anastomosis.

Area of Science:

  • Vascular Surgery
  • Microsurgery
  • Anatomical Studies

Background:

  • Internal mammary artery and vein are increasingly used for breast microvascular reconstruction.
  • Perforating branches of these vessels are emerging as potential recipient vessels.

Purpose of the Study:

  • To determine the location and diameter of internal mammary perforators.
  • To assess their suitability as recipient vessels for microvascular anastomosis.

Main Methods:

  • Cadaver study involving ten fresh cadavers.
  • Bilateral measurements of perforators in the first five interspaces using a micrometer and loupe magnification.

Main Results:

  • Largest arterial perforator averaged 1.74 mm in diameter.

  • Largest venous perforator averaged 1.78 mm in diameter.
  • Largest perforators were most frequently identified in the second intercostal space.

    • Conclusions:

    • Internal mammary perforators possess adequate diameter for successful microvascular anastomosis.
    • These perforators represent a viable option for recipient vessel selection in breast reconstruction.
