Internal mammary artery and vein: recipient vessels for free tissue transfer to the head and neck in the vessel-depleted neck.
BACKGROUND
Microvascular free tissue transfer is a standard reconstructive option for postablative defects of the head and neck. However, the success of this surgery requires suitable recipient vessels in the cervical region. This form of reconstruction can be particularly challenging in the vessel-depleted neck. While the internal mammary artery and vein (IMA/V) have been used extensively in breast reconstruction, there are few reports describing their use in head and neck reconstruction. We report the first case series of the use of the internal mammary vessels for head and neck microvascular reconstruction.


METHODS
We reviewed 5 cases of free tissue transfers to the head and neck in which extensive prior treatment precluded the use of more traditional recipient vessels in the neck or upper chest.


RESULTS
A variety of free flaps were transferred for different reconstructive problems which included: chin/lower lip (n = 2), closure of widely patent tracheoesophageal puncture sites (n = 2), and pharyngoesophageal reconstruction following staged repair of a severe stenosis (n = 1). The radial forearm free flap was transferred in 4 patients and the rectus abdominus free flap in 1 patient. The IMA/V on the right side was prepared in all cases. All free flaps were successfully revascularized without the need for vein grafts and without the need for any microvascular revision procedures.


CONCLUSIONS
The internal mammary artery and vein provide reliable, easily accessible recipient vessels for microvascular reconstruction in the vessel-depleted neck. The selection of free flap donor sites with long donor vessels facilitates the microvascular repair.
