RESUMO
Background: Rhabdomyolysis is a potentially fatal clinical syndrome resulting from the damage or breakdown of skeletal muscle, which can also lead to permanent disabilities. Based on our review of studies on rhabdomyolysis after prolonged surgeries, no other cases of rhabdomyolysis caused by muscle injury in the buttock area following breast reconstruction have been reported, making the current report the first to share information related to patient conditions and treatment progress in such cases. Case Description: Here, we present the case of a 57-year-old Asian patient with left breast cancer. We performed immediate breast reconstruction using a deep inferior epigastric perforator (DIEP) flap anastomosed to the internal mammary vessels after a skin-sparing mastectomy with sentinel lymph node biopsy. The surgery exceeded the estimated time because, after anastomosis, severe congestion was observed in the flap and because of the need to perform re-anastomosis and the reconstruction of the internal mammary vein twice. The surgical team eventually re-performed the breast reconstruction using a contralateral pedicled transverse rectus abdominis myocutaneous (TRAM) flap. The patient underwent breast reconstruction in a sitting position to ensure a symmetrical and natural breast shape resembling its original state. Additionally, a brown splint was placed underneath both legs to keep the hip and knees flexed to ensure donor-site closure when using an abdominal-based flap. The patient was closely monitored in the early postoperative period. On postoperative day (POD) 3, patient developed hypotension and was deemed to have experienced a hypovolemic shock. A complete laboratory workup was performed, and a rhabdomyolysis diagnosis was made based on the laboratory results. We believe that rhabdomyolysis resulted from prolonged pressure on the large gluteus maximus muscle located below the site of the pressure sore in the present patient. Conclusions: Postoperative rhabdomyolysis often results from prolonged surgery. Given the possibility of prolonged procedure time in patients undergoing breast reconstruction, the current case emphasizes the need to identify each patient's risk factors for rhabdomyolysis and prepare for possible rhabdomyolysis to prevent ischemic injuries and reduce the risk of complications such as hypovolemic shock.
RESUMO
To date, few studies have examined changes in waist circumference and cardiovascular risk profile (CVRP) after autologous breast reconstruction. Therefore, this study aimed to investigate the effect of flap surgery using autologous tissue on waist circumference and CVRP through a nationwide population-based cohort study. In total, 6926 patients who underwent autologous breast reconstruction between 2015 and 2019 were considered. Of them, we evaluated 3444 patients who underwent the complete Korean National Health Insurance Service Health Screening (NHIS-HealS) before and after surgery. Body measurements, including waist circumference, weight, and body mass index; and CVRP, including blood pressure, fasting blood glucose, and cholesterol levels, were analyzed by type of surgery up to 3-4 years postoperatively. The body measurements of patients who underwent abdominal-based breast reconstruction were reduced 1-2 years after surgery, but returned to preoperative values 3-4 years after surgery. Regardless of the type of surgery, CVRP was worsened at both 1-2 years and 3-4 years after surgery, except for low-density lipoprotein values. Autologous breast reconstruction did not ameliorate the deterioration of CVRP over time. In addition, the abdominoplasty effect of abdominal-based breast reconstruction disappeared 1-2 years after surgery.
RESUMO
PURPOSE: Partial breast reconstruction is challenging in medially located breast cancer, particularly in terms of achieving satisfactory aesthetic coverage. Thus, we aimed to investigate surgical strategies for filling medial defects resulting from breast-conserving surgery to improve patient satisfaction and aesthetic outcomes. METHODS: We retrospectively evaluated 113 patients (114 cases) with medially located breast cancer between 2007 and 2018. We analysed the patient data, such as breast size, specimen weight, complications, and aesthetic results obtained using a questionnaire. RESULTS: The mean body mass index and specimen weight were 23.43 kg/m² (range, 18.5-26.8) and 83.29 g (range, 15-290 g), respectively. The tennis racket and round-block techniques were chosen for small defects (< 10%-15%) in small- and medium-sized breasts. The rotational and perforator flap techniques were used for medium-sized defects. The latissimus dorsi (LD) flap technique was used for large defects (> 30%). Hematoma was found in 1 case (0.96%), linear skin necrosis was found in 1 case (0.96%), seroma in the LD flaps was found in 8 cases (7.69%); fat necrosis in the rotational flaps was found in 2 cases (1.92%); and fat necrosis in an anterior intercostal artery perforator flap was found in 1 case (0.96%). 91 patients (87.5%) were satisfied with the aesthetic results. CONCLUSION: The techniques used in this study for medially located breast cancer can produce fine aesthetic outcomes with regard to breast size and resection volume, with few complications.
RESUMO
The latissimus dorsi (LD) flap is one of the most useful techniques for autologous breast reconstruction, especially in Asians. However, for reconstruction of moderate to large volume breasts, it is difficult to achieve the desirable volume and projection with the classic extended LD flap. Although there is the option of concurrent application of an LD flap and a small silicone implant, this may lead to larger volume than desired; furthermore, an increasing number of patients prefer reconstruction with autologous tissue alone. In this case report, we present satisfactory outcomes for moderate to large breast reconstruction in three patients, using the boomerang LD flap technique, a modification of the conventional extended LD flap. The flap was harvested with a transverse incision along the brassiere line and a vertical incision under the arm adjusted for the breast width of the patient. Then, after tunneling to the breast, the autologous reconstructed breast was created with the boomerang LD flap before moving the flap. There were no severe intraoperative or postoperative complications. In one case, linear necrosis of the breast wound was observed and the patient underwent revision operation for treatment. Seromas were not observed in the donor site of the boomerang LD flap and healing was successful. However, the donor site incision was 1.5 to 1.6 times longer than that of the classic LD flap. Boomerang LD flaps allow immediate breast reconstruction after neoadjuvant chemotherapy, without the need of microsurgery or use of abdominal-based flaps and without using silicone implants.
