A Two-Year Retrospective Analysis of the Clinical Outcomes of Immediate Submuscular Breast Reconstructions With Native® Acellular Dermal Matrix.

BACKGROUND: Implant-based submuscular breast reconstruction (SBR) can be performed with the aid of acellular dermal matrices (ADM) for implant coverage on their inferolateral pole, aiming at providing a biological interface for hiding the implant and therefore reducing the risk of complications. The purpose of this study is to assess the long-term post-operative outcomes obtained using the SBR-specific Native® ADM (DECO med s.r.l., Marcon, Venice, Italy). METHODS: All cases of Native®-assisted immediate SBR performed at our institution between October 2016 and March 2020 were retrospectively analysed. Demographic and surgical data were collected, and post-operative outcomes, including minor and major complications, were evaluated. Particular attention was paid to complications emerging before and after patient discharge. Dependence analyses were performed to uncover statistically significant relationships between risk factors and reconstructive outcomes. RESULTS: Data on 100 patients were collected, for a total of 128 breasts. The mean age of the cohort was 49.5 years, the mean BMI was 23.4 kg/m2, and the mean follow-up was 24 months. Out of this, 14.1% of patients received pre-operative radiotherapy, while 16.4% underwent post-mastectomy radiotherapy. Breasts appeared to develop short-term minor complications more likely during hospitalisation (11.7% vs. 7.8%), while short-term major complications occurred more often after discharge (7.8% vs. 15.6%). The most frequent long-term complications were capsular contracture and contour defects (both 9.4%). Risk factors that showed a statistically significant relationship with complications were pre- and post-mastectomy radiotherapy and post-operative chemotherapy. CONCLUSIONS: The retrospective analysis showed results in line with clinical outcomes reported in the literature for the same reconstructive technique. The use of Native® ADM in SBR is safe and effective in the long term.

Comparison of Outcomes in Immediate Implant-Based Breast Reconstruction: Acellular Dermal Matrix versus Inferior Dermal Flap.

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.

Impact of Body Mass Index, Age and Tobacco Use on the Outcomes of Immediate Breast Reconstruction with Implants and Acellular Dermal Matrix.

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.

Gunshot upper extremity injury reconstructed with a fibula osteoseptocutaneous free flap (case report).

The management of upper extremity gunshot wound with soft tissue and bone injuries remains a remarkable problem and often requires sophisticated reconstructive strategies.There are limited reconstructive options for the treatment of segmental bone defects of the upper extremity exceeding 6 cm in length, especially when associated with soft tissue loss. Among the limited treatment options, the osteoseptocutaneous fibular transplantation is well established. The vascularized fibula flap has become a major tool in upper limb reconstruction but still is an uncommon procedure and continues to challenge reconstructive surgeons.In this paper, we report a complex combined skeletal and soft tissue involvement of an upper extremity case successfully treated with fibula osteoseptocutaneous free flap. The bone defect measured 12 cm. In severe injuries of the upper extremity, free transfer of the fibula flap not only provides replacement of the resulting composite defect but may also offer salvage of the extremity.

The use of forearm free fillet flap in traumatic upper extremity amputations.

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.

Repair of a large congenital diaphragmatic defect with a reverse latissimus dorsi muscle flap.

Advances in neonatal care have led to an increase in the survival rate of children with large congenital diaphragmatic defects. Reconstruction by direct closure is not usually possible and surgical correction in the newborn consists of synthetic patch closure. Recurrence and complications are high with this technique and a latter reconstruction with living tissue is now advocated. We report a case of congenital diaphragmatic hernia treated initially by synthetic patch closure and 10 months latter, after a recurrence, with a reinnervated reverse latissimus dorsi (RLD) flap. We used an end-to-side neural coaptation of the thoracodorsal nerve to the phrenic nerve. The result was satisfactory, with remission of symptoms and improvement in growth and development, with permanent pleuro-peritoneal separation, normal lung growth, and apparent neodiaphragmatic function.

Microsurgical reconstruction of chest wall defect after necrotizing fasciitis.

Chest wall necrotizing fasciitis is a rare and often fatal infection that usually requires extensive debridements and reconstructive procedures. We describe the therapeutical course of an uncommon case of perforating thoracic wound complicated with necrotizing fasciitis, with consecutive debridements and a resultant full-thickness subscapular defect. We agree that free flaps, although seldom required, must be considered when treating more complex defects. Latissimus dorsi free-flap was enough for pleural reconstruction and wall stabilization. There are no previous references in the literature to primary chest wall fasciitis treated successfully with microsurgical reconstruction.
