Summary:. 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.

Summary: The omental flap is often used to fill the space around the artificial vascular graft as a network sheet to prevent artificial vascular infection. In this study, we report a case in which the omental flap was divided into three parts to fill the dead spaces around the multiple-branched graft, as well as to wrap the suture lines of the graft after graft replacement in a patient with an infected thoracic aorta.An 88-year-old woman was admitted to the hospital with fever and impaired consciousness. Computer tomography revealed an aortic arch aneurysm with enlargement. After emergency stent–graft interpolation and antibiotic treatment, an infected thoracic aortic aneurysm was removed, and a multiple-branched graft replacement of the upper arch was performed. After harvesting an omental flap based on the right gastroepiploic vessels, the omental flap was divided into three on the basis of the epiploic vessels. The middle part of the omental flap was used to fill the space around the lesser curvature of the arch and the distal anastomotic site, the accessory part was used to fill the space between the ascending aorta and the superior caval vein, and the right part was used to wrap the three cervical branches, separately. Fifteen months after surgery, the patient had recovered enough to resume work without any signs of inflammation.

Summary: 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.

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. [ABSTRACT FROM AUTHOR]
