Local Infiltration of Tranexamic Acid (TXA) in Liposuction: A Single-Surgeon Outcomes Analysis and Considerations for Minimizing Postoperative Donor Site Ecchymosis.

BACKGROUND: Tranexamic acid (TXA) has gained increasing recognition in plastic surgery as a dependable adjunct capable of minimizing blood loss, ecchymosis, and edema. To date, there have been limited data on the utilization of TXA to mitigate liposuction donor site ecchymosis. OBJECTIVES: The authors sought to investigate whether infiltration of TXA into liposuction donor sites safely reduces postoperative ecchymosis. METHODS: A single-surgeon retrospective cohort study was performed to analyze patients undergoing autologous fat transfer for breast reconstruction between 2016 and 2019. Following lipoaspiration, patients in the intervention group received 75 mL of TXA (3 g in NaCl 0.9%) infiltrated into the liposuction donor sites, whereas the historical controls did not. Patient demographics, degree of ecchymosis, surgical complications, and thromboembolic events were examined. A blinded assessment of postoperative photographs of the donor sites was performed. RESULTS: Overall, 120 autologous fat grafting procedures were reviewed. Sixty patients received TXA, whereas 60 patients did not. Patient demographics and comorbidities were similar among the groups. No difference existed between groups regarding donor site locations, tumescent volume, lipoaspirate volume, or time to postoperative photograph. Ten blinded evaluators completed the assessment. The median bruising score of patients who received TXA was significantly lower than that of patients who did not (1.6/10 vs 2.3/10, P = 0.01). Postoperative complications were similar among the groups. Adverse effects of TXA were not observed. CONCLUSIONS: Patients who received local infiltration of TXA into the liposuction donor sites were found to have less donor site ecchymosis than patients who did not. Further prospective randomized studies are warranted.

Inferior pedicle breast reduction and long nipple-to-inframammary fold distance: How long is safe?

BACKGROUND: Free nipple grafting indications in breast reduction surgery are outdated. Safety of inferior pedicle technique for large resections and long pedicles has not been clearly defined. We evaluated patients who underwent inferior pedicle reduction mammoplasty to define the safety constraints of the inferior pedicle. METHODS: A retrospective review of patients who underwent inferior pedicle reduction mammoplasty due to symptomatic macromastia at Mayo Clinic over a six-year period was conducted. Patients with prior breast surgeries were excluded. Demographics, breast measurements, and surgical outcomes were collected. Univariate and multivariate analyses were performed to assess for predictors of necrosis. RESULTS: Overall, 288 patients (576 breasts) underwent inferior pedicle breast reduction from 2014 to 2019. The mean sternal notch-to-nipple (SNN) distance was 31.5 cm (standard deviation[SD]:4.2; range[r]:16-48), and the mean nipple-to-inframammary fold (N-IMF) distance was 14.8 cm (SD:4.0; r:7.5-27). The mean resection weight was 699.6 g (SD:310.4; r:125-2,385). The median follow-up was 3.9 months (interquartile range[IQR]:2.8-9.0). The overall skin or nipple areolar complex necrosis rate was 2.1%; the overall complication rate was 14.8%. On multivariate analysis, overall necrosis was not found to be associated with the N-IMF distance (adjusted odds ratio[aOR]:1.05, 95%-CI 0.88-1.16). Resection weight was statistically associated with an increased risk of overall necrosis (aOR:1.003, 95%-CI 1.001-1.005), adjusting for N-IMF and SNN distances. CONCLUSION: Inferior pedicle breast reduction offers low risk of necrosis and can be safely performed in patients regardless of the N-IMF distance. No association was found between N-IMF distance and overall necrosis in our cohort, including lengths >15 cm. However, large resections could increase the risk of necrosis.

Risk Factors for Lymphedema after Thigh Sarcoma Resection and Reconstruction.

Secondary lymphedema can be a lifelong and debilitating consequence of lower extremity oncologic resection and reconstruction. The goal of this study was to identify risk factors for the development of lymphedema in patients treated for thigh sarcoma. METHODS: A retrospective review analyzed all patients who underwent thigh sarcoma resection and reconstruction by a plastic surgeon at the Mayo Clinic between 1997 and 2014. Patient demographics, tumor characteristics, surgical management, adjunctive therapies, and complications of patients who did and did not develop postoperative lymphedema were compared. RESULTS: A total of 148 patients were identified. Twelve percent of patients developed lymphedema postoperatively during an average follow-up of 26 months. Risk factors for the development of lymphedema included defect location in the medial thigh (P = 0.04), arterial resection (P = 0.001), arterial reconstruction (P = 0.027), and a history of cardiac disease (P = 0.03). Twenty-two percent of patients who developed lymphedema also experienced wound dehiscence compared with 4.6% of patients without lymphedema (P = 0.02). There were no differences in age, body mass index, smoking, history of deep venous thrombosis or venous stasis, wound dimensions, or type of reconstruction performed in patients with and without lymphedema. CONCLUSIONS: Lymphedema is common following major oncologic resection. Preexisting cardiac disease, tumor location in the medial thigh, and arterial resection and reconstruction were associated with a higher risk of postoperative lymphedema. Noninfectious wound dehiscence may be secondary to lymphedema or represent an early indicator of patients who will ultimately develop lymphedema.

Complications after thigh sarcoma resection.

BACKGROUND AND OBJECTIVES: Standard treatment for extremity sarcoma is limb-sparing surgery often with radiation, but complications occur frequently. We sought to determine factors predictive of wound complications after thigh sarcoma resection and reconstruction while analyzing trends over time. METHODS: We reviewed all thigh defects requiring plastic surgeon reconstruction following sarcoma resection at our institution from 1997 to 2014. Patient demographics, comorbidities, operative characteristics, multi-modality therapies, and complications were analyzed. Wound complications were: infection, dehiscence, seroma, hematoma, or partial/total flap loss. RESULTS: There were 159 thigh reconstructions followed for 30 months on average. Eighty-seven percent of patients underwent radiation and 42% had chemotherapy. Almost half (49.1%) had a complication. The most common wound complication was surgical site infection (23.3%) followed by dehiscence (19.5%), and seroma (10.7%). Less common were partial (2.5%) or total flap loss (0.6%). Reoperation was required in 21 patients (13.2%). Tobacco use, older patient age, cardiac disease, and higher body mass index were independently associated with wound complications. Complications trended towards decreasing over time, but this was not statistically significant. CONCLUSIONS: Tobacco use, cardiac disease, and higher body mass index, but not the timing of reconstruction, appear to increase the risk of wound complications after thigh soft tissue sarcomas resection and plastic surgery reconstruction.

A Simple Alternative: A Minimal-Touch Technique for Placing Breast Implants.

This is a single-surgeon experience detailing the senior author's (J.G.) minimal-touch technique for placement of breast implants. Adams et al. 14-point plan has been incorporated into the technique, and the implant box paper cover sheet is used as a barrier between the patient and the implant near the incision during placement. Over a period of ten years, the senior author reports a less than 1% development in capsular contracture using this technique and no implant fractures. These findings elucidate the importance of describing this alternative technique to other barriers currently on the market.

A reconstructive algorithm after thigh soft tissue sarcoma resection including predictors of free flap reconstruction✰.

BACKGROUND: Reconstruction of defects of the thigh after oncologic resection plays a vital role in limb salvage. Our goal was to evaluate our institution's experience on thigh sarcomas to develop evidence-based recommendations to guide the reconstructive surgeon, including factors that would predict the need for free flap reconstruction. METHODS: We reviewed all thigh defects requiring plastic surgeon reconstruction following sarcoma resection at our institution from 1997 to 2014. Patient demographics, comorbidities, multimodality therapies, and operative characteristics were analyzed. RESULTS: There were 159 thigh reconstructions. Reconstruction was achieved by primary closure (15%), skin graft (13%), local fasciocutaneous flap (8%), local muscle flap (31%), regional muscle flap (28%), or free flap (4%). For the proximal third of the thigh, the most common flaps were pedicled thigh muscle and rectus abdominis flaps; for the middle third of the thigh, it was pedicled thigh muscle flaps; and for the distal third, it was pedicled gastrocnemius muscle flaps. Factors shown to be predictive of requiring a free flap included wide defects (p = 0.03) and location in the middle third of the thigh (p = 0.001). CONCLUSION: There are multiple options for reconstructing defects from thigh STS. When primary closure and skin grafts are not an option, most defects can be closed with pedicled local or regional muscle or fasciocutaneous flaps. Free flap reconstruction is rarely required but can be necessary when defects are wide or located in the middle third of the thigh.

Management of a late breast implant rupture in the setting of previous radiation.

Management of ruptured breast implants is scarcely discussed in the literature, especially in the setting of previous breast cancer and radiation. The authors present an uncommon presentation of late breast implant rupture with seroma and history of prior radiation. It is important to acknowledge the increased risk of wound healing complications in patients who are several years' postradiation therapy for breast cancer and should be an important factor when discussing treatment options with the patient.

Tissue Expanders in Skin Deficient Ventral Hernias Utilizing Component Separation.

Skin deficient complex ventral hernias are complicated surgical cases that have multimodal approaches. There is no current consensus on the management of those patients who also have concomitant stomas or enterocutaneous fistula. We present 2 cases in which the senior authors were able to apply tissue expanders above and between the abdominal wall in patients with an enterocutaneous fistula or stoma. After expansion and final closure, the patients did not experience recurrent hernias.

What's new in objective assessment and treatment of facial hyperpigmentation?

Facial hyperpigmentation is common and challenging to treat in darker-skinned populations. A Medline literature search of articles published up to October 2013 reporting the objective assessment of and/or treatment for melasma, postinflammatory hyperpigmentation, dermatosis papulosa nigra, lichen planus pigmentosus, and erythema dyschromicum perstans was reviewed. Objective assessment was only reported for melasma and postinflammatory hyperpigmentation. Furthermore, randomized controlled trial evidence was only reported for melasma. Although progress has been made, there is a need to develop more objective outcome measures and effective treatments for hyperpigmentation.

2-[(Naphthalen-1-yl-methyl-idene)amino]-5-methyl-phenol.

The title compound, C(18)H(15)NO, is a Schiff base prepared from an acid-catalyzed condensation reaction between 1-naphthaldehyde and 6-amino-m-cresol. Intra-molecular hydrogen bonding occurs via an O-H⋯N inter-action, generating an S(5) ring motif. Neighboring phenol groups participate in inter-molecular hydrogen bonding through an O-H⋯O inter-action, forming chains. The O atom of the phenol group also participates in an intermolecular C-H⋯O interaction with an H atom of one of the naphthalene rings. The C-N=C-C torsion angle between the phenol and naphthalene rings is -179.8 (2)°. Crystal packing involves stacks with the mol-ecules inter-acting through the π-systems of the C=N with both the phenol system and one of the naphthalene rings.
