Breast Cancer
Conditions
Brief summary
The investigators hope to learn the value of the SPY ELITE® intra-operative angiography in reducing post-operative complications associated with low breast skin blood flow after breast reconstruction using implants.
Detailed description
Breast cancer is the most common malignancy among women, and over 180,000 women will be diagnosed with this disease in 2008. Last year, over 57,000 breast reconstructive procedures were performed, of which prosthetic reconstruction constituted 76%. Immediate reconstruction has been favored over delayed procedures for psychological and technical reasons. However, immediate breast reconstruction is associated with significantly higher complication rates (50-52%) than delayed procedures (32-36%), especially when a prosthetic technique is used. For prosthetic reconstructions, the most significant early complications include necrosis of the mastectomy skin flaps, infection, delayed wound healing and exposure of the implant. The published incidence of these complications ranges between 10% and 40% and is predominantly associated with malperfusion of mastectomy skin flaps. Thus, evaluation of skin perfusion and elimination of poorly vascularized areas could help reduce the high rate of complications in immediate breast reconstruction.
