According to the study, reported in the Oct. 2011 issue of Plastic and Reconstructive Surgery, end-to-side anastomosis increased mean ischemia time by about 20 minutes, compared with more traditional end-to-end anastomosis. The two techniques resulted in similar outcomes.

According to the report, the mammary artery requires a shorter pedicle than the thoracordosal arteries for microvascular breast reconstruction.

The internal mammary artery also facilitates medial placement of flap issue and helps the patient avoid axillary scarring.
