Results of our analysis show as that breast reconstruction become a standard part of the care of female patients with breast cancer We will analyse the factors that are important for the primary or secondary breast reconstruction after mastectomy, and also take a closer look on the most recent scientific advances on breast reconstruction and on the protocols regarding them. The breast is the most common site of cancer in Croatia women. Breast cancer is the first leading cause of cancer death among women today. The incidence of female breast cancer in Croatia estimates that approximately 2.200 news cases of female breast will be diagnosed every year. We retrospectively analysed data of 101 female patients undergoing reconstructive surgery for breast reconstruction after mastectomy at Division of Plastic Surgery and Burns, University Hospital Center Split and University Clinic of Plastic and Reconstructive Surgery, Innsbruck, Austria, between 1998 and 2008. For the purpose of outcome assessment, we performed the tree different type of questionnaire: (1) Personal/medical profile (Table 1), (2) Aesthetic assessment (Table 2), and (3) Psychosocial assessment (Table 3). The occurrence of main complications during breast reconstruction (partial necrosis of flap, hernia of donor site, pulmonary embolism, deep venous thrombosis, infection rate, hemathoma and seroma formation, and extrusion of expander/implant) during hospitalisation and follow up period until 6 post operatively were analysed with respect to use different type of reconstructive methods for breast reconstruction. The difference in complication between patients groups was evaluated by chi2-test. The level of significance was set up at p = 0.05. Mann-Whitney test was used to compare the time from mastectomy to breast reconstruction, due to asymmetrical data distribution. The three main variables of this study were to identify significant risk factors, asses the aesthetic outcome, and patient satisfaction with performed different methods for breast reconstruction (LD flap with or without tissue expander and implant, pedicle and free TRAM flaps, and expander /implants only. These variables determined the current guidelines for early and late breast reconstruction after mastectomy such as patient data, age and own decision, relation ship between reconstruction and radiotherapy, and chemotherapy, and finally about breast preserving operation. The result should confirm that breast reconstruction after mastectomy is justified, especially in young women, as well as how essential is team work involved in breast cancer operation and breast reconstruction after mastectomy.
