Abstract
INTRODUCTION: The deep inferior epigastric perforator (DIEP) flap is a reliable and reproducible technique for autologous microsurgical breast reconstruction. Several recipient vessels sites for microvascular anastomosis have been described such as the internal thoracic vessels, the thoracodorsal vessels, and the circumflex scapular vessels. Nonetheless, the choice of the recipient site depends mainly on individual operator's experience and preferences, and currently the best recipient vessel site is under debate. This anatomical observational study aimed to determine whether anatomy could address this dilemma by determining the best vessel diameter to match the donor with these three recipient sites.
METHODS: Our series reports 80 dissections of the three anatomical regions of interest. Forty formalin-preserved female cadavers were dissected bilaterally. Internal vessels diameter measurements were recorded with a vascular gauge ranging from 1.0 to 5.0 mm with successive half-millimeter graduations.
RESULTS: The median diameter of the deep inferior epigastric (DIEA), internal thoracic (ITA), circumflex scapular (CSA), and thoracodorsal arteries (TDA) were: 2.0, 2.5, 2.5, and 1.5 mm, respectively. The median diameter of the deep inferior epigastric, internal thoracic, circumflex scapular, and thoracodorsal veins were: 3.0, 3.0, 3.0, and 2.5 mm, respectively. At the individual level, the perfect match between DIEA and ITA was significantly more frequent than between DIEA and TDA (p = 0.002), and it was more frequent between DIEA and CSA than between DIEA and TDA (p = 0.009).
CONCLUSIONS: This study supports the use of the internal thoracic pedicle as the first recipient vessel choice, which should be considered, at least anatomically, as the best one with the closest diameter matching with the donor pedicle.
