RESUMO
Background Implant-based breast reconstruction has evolved tremendously in the last decades, mainly due to the development of new products and techniques that make the procedure safer and more reliable. The purpose of this study was to compare the outcomes in immediate one-stage breast reconstruction between acellular dermal matrix (ADM) and inferior dermal flap (IDF). Methods We conducted a retrospective comparative study of patients submitted to immediate breast reconstructions with an anatomical implant and ADM or IDF in a single center between 2016 and 2018. Outcomes evaluated included major complications, early complications, reinterventions, readmissions, and reconstruction failure. Simple descriptive statistics and univariate analysis were performed. Results A total of 118 breast reconstructions (85 patients) were included in the analysis. Patients in the IDF group had a higher body mass index (median = 27.0) than patients in the ADM group (median = 24). There were no statistically significant differences among both groups regarding immediate major complication, early complications, readmissions, and reinterventions. Conclusion There are no significant differences in complications between the ADM and IDF approach to immediate implant breast reconstruction. In patients with higher body mass index and large, ptotic breasts, we recommend an immediate implant reconstruction with IDF.
RESUMO
Background This study aimed to analyze the effect of body mass index (BMI), age, and tobacco use on alloplastic breast reconstruction. Methods We conducted a retrospective study of patients who submitted to immediate breast reconstructions with an anatomical implant and acellular dermal matrix in a single center between 2016 and 2018. Outcomes evaluated included immediate complications, early complications, reinterventions, readmissions, and reconstruction failure. Patients were divided into two groups concerning each potential risk factor (BMI < or ≥25; age < or ≥ 50 years; and smokers vs nonsmokers). Simple descriptive statistics and univariate analysis were performed. Results A total of 101 breast reconstructions (73 patients) were included in the analysis. The mean BMI was 24, and the mean age was 44.5 years old. Smokers accounted for 14 breast reconstructions (13.9%). The rate of early infections, mastectomy flap necrosis, and implant removal was significantly higher in overweight patients. The total volume of breast drainage was higher in the age ≥ 50 years group. Smoking did not alter the outcomes. Conclusions A BMI ≥ 25 is a risk factor for early infections and reconstructive failure. Age ≥ 50 years is associated with a higher volume of breast drainage but does not seem to impact the success of the reconstruction. Smoking does not appear to affect the outcomes significantly in this type of reconstruction. Surgeons should consider delaying the reconstruction or using autologous tissue when patients are overweight.
RESUMO
BACKGROUND: Complete traumatic upper extremity avulsions are an infrequent but devastating injury. These injuries are usually the result of massive blunt trauma to the upper limb. Intact issue from amputated or nonsalvageable limbs may be transferred for reconstruction of complex defects resulting from trauma when the indications for replantation are not met. This strategy allows preservation of stump length or coverage of exposed joints, and provides free flap harvest for reconstruction without additional donor-site morbidity. METHODS: A retrospective review at São João Hospital was performed on seven patients who had undergone immediate reconstruction with forearm free fillet flaps between 1992 and 2007. RESULTS: There were six men and one woman, with patient age ranging from 17 to 74 years (mean, 41 years). Amputation sites were at the humeral neck (n = 1), at the humeral shaft (n = 5), and below the elbow (n = 1). The area of the forearm free fillet flap skin paddle was 352.14 +/- 145.48 cm (mean +/- SD). The two major complications were the flap loss and the patient death on postoperative day 3 in other case. The postoperative course in the remaining five cases was uneventful with good healing of the wounds. Minor complications included two small residual defects treated by split-thickness skin grafting and one wound infection requiring drainage and revision. CONCLUSIONS: The forearm free fillet flap harvested from the amputated limb provides reliable and robust tissue for reconstruction of large defects of the residual limb without additional donor-site morbidity. Microsurgical free fillet flap transfer to amputation sites is valuable for achieving wound closure, improving stump durability, and maximizing function via preservation of length.
