Popis: The vessel-depleted neck situation is a challenge for the surgeon in search of suitable recipient vessels for microvascular reconstruction of the head and neck. The internal thoracic vessels (ITVs) have proven useful as "rescue" recipient vessel resource. The objective of this report is to assess the feasibility of using ITVs by rerouting the pedicle for free flap reconstruction of the head and neck by comparing two different approaches.Two surgical approaches were assessed: the classical one is parasternal, but cardiac surgeons commonly use median sternotomy. We conducted an anatomical study, comparing on the same subject the lengths and diameters of both internal thoracic artery (ITA) and internal thoracic vein (ITV) at the sixth, fifth, and fourth intercostal spaces (ICSs) through parasternal approach on one side and by median sternotomy on the other side.The study was performed on 13 subjects. We found a superiority of length of the ITVs with the median sternotomy approach. Regarding the mean length of the ITA, the sternotomy approach allowed a significant greater length with 119/89/67 mm, compared with parasternal approach with 91/62/42 mm, respectively at the sixth, fifth, and fourth ICS (p0.001). Similarly, we observed a significant greater length of the ITV with 116/85/63 mm versus 89/62/42 mm (p0.001). The mean arterial and venous diameters were 2.9 mm and 2.1 mm in the sixth ICS, 3.3 mm and 2.3 mm in the fifth ICS, and 3.9 mm and 2.9 mm in the fourth ICS, respectively.These results help to guide the choice of surgical approach and the level of harvesting.
