Experiences with internal thoracic vessels in breast reconstruction with the free TRAM flap

Abstract

In breast reconstruction with free TRAM flaps, the thoracodorsal vessels are most commonly used as recipient vessels. In case of an irradiated and scarred axillary region, the internal thoracic vessels may be an alternative. In the pertinent literature it has been pointed out that the veins may be fragile and thin and, thus, not suitable for microvascular anastomosis. In a series of 31 breast reconstructions with free TRAM flaps, the internal thoracic vessels were dissected and evaluated in 24 cases in order to assess the value of this vascular system as a recipient site for free flap transplantation. In four cases, the veins were too small for anastomosis, and in one case the artery was severed during dissection. End-to-end anastomoses were performed in 19 cases (79%). The following complications were recorded: One marginal necrosis; one venous thrombosis, which was detected and salvaged by revision; one recurrent arterial thrombosis, resulting in flap loss; one pleural lesion healed uneventfully.
