Three-dimensional reconstruction of hip and groin region by division and rotation of skin paddle using oblique rectus abdominis musculocutaneous flap after squamous cell carcinoma resection.

Reconstructing extensive defects in the hip and groin region is challenging. Although the technique of wrapping the flaps is often chosen, achieving effective coverage of defects is difficult because of the tissue bulge in the center, and a skin graft is frequently required. We herein report a case of successful hip "corner" reconstruction using a pedicled oblique rectus abdominis musculocutaneous flap with division and rotation of the skin paddles after squamous cell carcinoma resection. The patient had a history of immunosuppressive treatment, radiation therapy, and surgeries on the ipsilateral thigh. Our technique minimized the sacrifice of the flap donor site, achieved primary closure, and resulted in a favorably shaped reconstruction with respect to three-dimensional morphology. The patient's postoperative quality of life was ultimately improved.

A Shaped Pectoralis Major Muscle Flap under Indocyanine Green Fluorescence Angiography for Sternal Wound Infection.

The treatment of a sternal wound infection is challenging because it requires radical debridement and reconstruction with a well-vascularized flap. The defects after debridement are three-dimensionally complex, especially if synthetic grafts are involved. Although the pectoralis major muscle (PMM) flap is useful for reconstruction, it is difficult to fill up the complex dead space surrounding the vascular prosthesis when using a conventional PMM flap. Herein, we describe a new technique of splitting and shaping the PMM flap to fit the complex defect. Intraoperative indocyanine green fluorescence angiography was used to assess dynamic blood flow of the PMM supplied by internal mammary artery perforators. This technique allows the PMM flap to be split and shaped to securely fit the dead space, which may improve the healing rate.

Ruptured breast implant removal because of patient anxiety in the absence of breast implant-associated anaplastic large cell lymphoma.

Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) has been regarded as a long-term problem after silicone breast implantations. We report a case in which BIA-ALCL and breast cancer were not detected preoperatively, with subsequent removal of a ruptured breast implant. A 52-year-old woman had silicone breast implants on both sides for breast augmentation 15 years ago. Right axillary lymphadenopathy and intracapsular ruptures were noted by magnetic resonance imaging. Right axillary lymph node biopsy was performed at our department of breast surgery. Flow cytometry for BIA-ALCL was also performed using the exudate around the implant. The results were negative for breast cancer and BIA-ALCL. However, taking into consideration exacerbation of breast implant rupture and the patient's anxiety about BIA-ALCL, ruptured bilateral implants were removed by total capsulectomy. The postoperative course was uneventful 1 year after the operation, and her anxiety was dispelled despite her breast deformity. Appropriate explantation and periodic examination may be required to prevent excessive anxiety.

Breast reconstruction in a patient with an implanted deep brain stimulator.

Deep brain stimulators (DBSs) are sometimes used to treat refractory movement disorders such as Parkinson's disease. When DBSs are implanted in a subcutaneous pocket in the chest region, breast reconstruction becomes a challenge because monopolar electrocautery can lead to DBS dysfunction or brain tissue damage caused by heat. We report a patient with a DBS who underwent one-stage implant-based breast reconstruction. We switched off the DBS before surgery and used monopolar electromagnetic cautery with minimum power settings to undermine the subcutaneous pocket for the breast implant. The DBS was switched back on immediately after completion of the surgery. The patient's postoperative recovery was uneventful with the DBS fully functional.
