Double Layer Reconstruction of Exposed Cardiac Implantable Electronic Devices in Elderly Patients.

Background Elderly patients with multiple comorbidities may not be candidates for cardiac implanted electronic device (CIED) explantation in cases of exposition. Excision of all unhealthy and inflamed scar tissue results in a skin defect that must be covered. Small- to moderate-sized local skin flaps and subpectoral placement of CIEDs have been described in the literature. However, these techniques still could not eliminate the risk of recurrence. In terms of minimizing the recurrence risk, we aim to increase the flap dimensions for getting better circulation and tension-free closure after subpectoral placement. Material and methods Six patients who were operated for a dual-layer reconstruction of exposed cardiac implants between 2017 and 2020 were included in the study. All patients were referred to plastic surgery as soon as the wound biopsy culture results were negative after systemic and topical antibiotic treatment by cardiology department. Results No flap loss or wound dehiscence was seen with a mean duration of 11 months follow-up. Early hematoma was encountered in a patient who was managed with irrigation and drain renewal. One patient developed suture abscess in the second month postoperatively. Knots were removed and wound healed without further intervention. Conclusion Double layer closure of exposed cardiac implants with large breast fasciocutaneous flap after subpectoral placement of pulse generator and leads suggest durable and reliable coverage in elderly patients with multiple comorbidities.

Successful Replantation of Tamai Zone I Amputation with Delayed Vein Repair.

Digital vein repair is one of the most challenging phases of distal phalanx replantation. Digital veins at very distal levels have a small vessel caliber and collapsed lumens, which makes them hard to identify and handle. Digital veins may not be visible immediately after arterial anastomosis. In this scenario, the patient can be taken to the operative room several hours after revascularization to visualize dilated and expanded veins for late digital vein repair. Late digital vein repair is a reliable and alternative method to artery only replantation. In this report, a successful replantation with late digital vein repair in Tamai Zone I is presented.

Clinical Experiences with Closed Incisional Negative Pressure Wound Treatment on Various Anatomic Locations.

Background Closed incisional negative pressure wound treatment (ciNPWT) is one of the promising methods for the prevention of complications in surgical incisions. The mechanisms of ciNPWT have previously been elucidated and in this series, we demonstrate various, as of yet, underreported uses for the technology. Our aim is to share our experience with ciNPWT on various anatomic sites with novel indications.  Materials and methods ciNPWT was used in 24 patients. The mean age was 49.6. All the incisions were sutured, clean, and non-infected. Patients' sex, age, comorbidities, anatomic location of the wound, and the indications for ciNPWT were recorded. Results The mean number of applications was three per patient. One suture dehiscence after one session of ciNPWT was encountered in a flap donor site of an infant operated for meningomyelocele. Late-term seroma and hematoma formation were encountered in two patients. No surgical site infection, wound dehiscence, and ciNPWT related complications were seen in other patients. The majority of the applications were on the trunk, lower extremity, pelvis, upper extremity, and scalp respectively. Indications for ciNPWT utilization were preventing dehiscence, seroma, and hematoma formation in the majority of the patients. Conclusion ciNPWT is reliable and effective in the prevention of post-operative wound dehiscence and surgical site infections. It can be used safely in various locations and different indications for preventingcomplications such as preventing dehiscence in revision surgeries, cerebrospinal fluid (CSF) fistula formation in the scalp, and wound breakdown in chronic corticosteroid use.

Nonmelanoma Skin Cancers in Solid-Organ Transplant Recipients: A Single Center Experience.

OBJECTIVES: Skin cancers are one of the most common malignancies in solid-organ transplant recipients. Increased age and immunosuppressive drug use are risk factors for posttransplant skin malignancies. We evaluated nonmelanocytic skin cancer incidence and development time in transplant patients. MATERIALS AND METHODS: We reviewed 1833 patients who received kidney, liver, and heart grafts between 1996 and 2016 at Baskent University. We excluded melanocytic skin cancers, premalignant lesions, and benign skin tumors. RESULTS: Of 1833 patients, 1253 were male (68.4%) and 580 were female (31.6%), composed of 1133 kidney (61.8%), 512 liver (27.9%), and 120 heart recipients (6.5%). Of these, 22 patients (18 kidney/3 liver/1 heart) developed 23 different types of skin cancer. Prevalence of skin cancer was 1.20%. Mean age at presentation was 55.8 years (range, 37-71 y). Average time from transplant to skin malignancy was 6.1 years (range, 1-13 y), with the most common being basal cell carcinoma (43%, 10 cases), followed by squamous cell carcinoma (39%, 9 cases) and Kaposi sarcoma (13%, 3 cases). Tumor sites included head and neck (15 case), trunk (2 cases), lower extremity (2 cases), and upper extremity (2 cases). Neither local recurrence nor distant metastasis was shown. CONCLUSIONS: Skin cancer risk is increased in solid-organ transplant recipients versus the general population. Although squamous cell carcinoma is the most common tumor in this patient population, followed by basal cell carcinoma, we found this reversed in our patients. The low prevalence of skin malignancy (1.20%) may be associated with close clinical follow-up to detect premalignant skin lesions and the lowdose immunosuppressive drug regimen. We believe that local recurrence and distant metastasis were absent because we use a wide surgical margin of excision and provide strict follow-up. Routine dermatologic follow-up visits of transplant recipients are recommended to detect and treat early skin cancer and premalignant lesions and thus lower morbidity and mortality.

Aesthetic Surgery in Transplant Patients: A Single Center Experience.

OBJECTIVES: Transplant patients, like the nontransplant population, can have surgical interventions for body shape disorders. Studies on aesthetic surgeries in transplant patients are scarce. Our aim was to share our experiences with various aesthetic procedures in solid-organ transplant recipients. MATERIALS AND METHODS: Six (5 female, 1 male) transplant patients who received surgical corrections of the aging face, ptosis and lipodystrophy of the breast, and abdomen at the Baskent University Plastic Reconstructive and Aesthetic Surgery Department between 2010 and 2017 were included. Five patients had renal transplants, and 1 patient had liver transplant. Minimal aesthetic procedures, including botulinum toxin, dermal filler injections, and scar revisions, were excluded. All patients were consulted to transplant team preoperatively and hospitalized in the transplant inpatient clinic. RESULTS: Mean age was 46 years. Aesthetic surgeries included breast reduction (2 patients), high suprasuperficial musculoaponeurotic system face lift (1 patient), blepharoplasty (2 patients), and dermofat grafting (1 patient). Mean hospitalization duration was 2.5 days. Four patients had no minor or major complications. One patient had skin flap necrosis, which healed with secondary intention. Another patient had ectropion after lower lid blepharoplasty, which was corrected with another procedure. CONCLUSIONS: Transplant patients are a special group of patients who receive long-term immunosuppressive treatment and medications like high-dose steroids. These treatments can lead to dermal atrophy and cause pseudo-skin laxity. Removal of excess skin and fat tissue should be considered. Efforts should be made to avoid complications such as skin necrosis and unpredictable wound healing problems when resecting the excess tissue. Preoperative consultation with transplant surgeons and keeping operative times short are other important factors. Body dysmorphologies that interfere with normal life activities and demand for younger appearance are the main reasons of aesthetic procedures. Transplant patients can be operated safely with preoperative planning, consultation with transplant surgeons, and close follow-up.

The effect of adipose derived stromal vascular fraction on stasis zone in an experimental burn model.

BACKGROUND: Stasis zone is the surrounding area of the coagulation zone which is an important part determining the extent of the necrosis in burn patients. In our study we aim to salvage the stasis zone by injecting adipose derived stromal vascular fraction (ADSVF). METHODS: Thermal injury was applied on dorsum of Sprague-Dawley rats (n=20) by the "comb burn" model as described previously. When the burn injury was established on Sprague-Dawley rats (30min); rat dorsum was separated into 2 equal parts consisting of 4 burn zones (3 stasis zone) on each pair. ADSVF cells harvested from inguinal fat pads of Sprague-Dawley rats (n=5) were injected on the right side while same amount of phosphate buffered saline (PBS) injected on the left side of the same animal. One week later, average vital tissue on the statis zone was determined by macroscopy, angiography and microscopy. Vascular density, inflammatory cell density, gradient of fibrosis and epithelial thickness were determined via immunohistochemical assay. RESULTS: Macroscopic stasis zone tissue viability (32±3.28%, 57±4.28%) (p<0.01), average number of vessels (10.28±1.28, 19.43±1.72) (p<0.01), capillary count (15.67±1.97, 25.35±2.15) (p<0.01) vascular density (1.55±0.38, 2.14±0.45) (p<0.01) epithelial thickness (0.014±0.009mm, 0.024±0.0011mm) were higher on ADSVF side. Fibrosis gradient (1.87±0.51, 1.50±0.43) (p<0.01) and inflammatory cell density (1.33±0.40, 1.20±0.32) (p<0.01) were higher on the PBS side. CONCLUSION: Macroscopic and microscopic findings determined that ADSVF has a statistically significant benefit for salvaging stasis zone on acute burn injuries.
