Item Double Layer Reconstruction of Exposed Cardiac Implantable Electronic Devices in Elderly Patients(2021) Ozkan, Burak; Albayati, Abbas; Yilmaz, Kerem C.; Ciftci, Orcun; Ozin, Bulent; Uysal, Cagri A.; Ertas, Nilgun Markal; 0000-0001-8926-9142; 33542888; AAJ-1331-2021; W-5233-2018Background 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.Item Clinical Experiences with Closed Incisional Negative Pressure Wound Treatment on Various Anatomic Locations(2020) Ozkan, Burak; Ertas, Nilgun Markal; Bali, Ulas; Uysal, Cagri A.; 0000-0003-3093-8369; 0000-0001-6236-0050; AAI-5063-2020; AAJ-2949-2021Background 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 preventing complications such as preventing dehiscence in revision surgeries, cerebrospinal fluid (CSF) fistula formation in the scalp, and wound breakdown in chronic corticosteroid use,Item Effect of long-term intermittent hypothermia on random skin flap viability and new vessel formation(2020) Caglar, Ibrahim Baris; Ozkan, Burak; Albayati, Abbas; Uysal, Ahmet Cagri; Ertas, Nilgun Markal; 0000-0001-6236-0050; 0000-0003-2806-3006; AAJ-2949-2021; AAC-3344-2021Background: Preconditioning is the improving the overall viability of the flaps before surgery. Hypothermia is one of preconditioning methods. In literature, the effect of short time hypothermia in skin flap viability has been studied. However, there is no information about the effects of long-term application of hypothermia on skin flap viability. In this study, we investigated the effect of long-term local hypothermia on flap viability and new vessel formation on random pattern skin flaps. Materials and Methods: Thirty-six adult male Sprague-Dawley rats were used. The flap model was, 3 cm x 9 cm sized random pattern skin flap. Three groups were composed as control group, continuous hypothermia induction group with ice bags, and intermittent hypothermia induction with chloroethyl spray. Flaps were raised on the 15th day of hypothermia sessions. Flap viability was measured in the software program. Microangiography and blood vascular endothelial growth factor (VEGF) levels were assessed for the detection of new vessel formation. Results: Average flap viabilities were found to be 64.87% in Group I, 57.69% in Group II, and 62.22% in Group III. The difference between Group II and other groups were statistically significant. When microangiographies were examined macroscopically, diameters, and amount of vascular branches of vessels in Group II were found to be higher than other groups. The difference between blood VEGF levels day 1 values among groups was not statistically significant. When day 4 values were compared to baseline values difference in Group III was statistically significant. At days 7 and 15, differences between groups and corresponding baseline values were not statistically significant. Conclusion: Continuous long-term application of hypothermia with ice-water bags causes a significant increase in neovascularization in random pattern skin flaps without an increase in skin flap viability. Hence, we can say that 2 weeks of hypothermia on random pattern skin flaps is not an efficient preconditioning method in clinical use.Item Clear Cell Acanthoma in an Unexpected Location(2018) Togral, Arzu Karatas; Eyuboglu, Atilla Adnan; Akcay, Eda Yilmaz; Ertas, Nilgun MarkalClear cell acanthoma (CCA) is an uncommon, benign, and slow progressing lesion originating from epidermal keratinocytes. Lesions are not gender specific and usually diagnosed at 50-60 years of age. It is generally represented in the lower extremities. CCA was first described by Degos et al. as "Degos acanthoma" for a lesion presented in the lower extremity. Clinically, it is hard to distinguish whether the lesion is benign or malignant. Final diagnosis can be made histopathologically. Biopsy material is periodic acid-Schiff positive. While CAA commonly presents itself in the lower extremities, our patient had a CAA in his abdominal region.Item Stewart-Treves Syndrome: A Case Report and Review of Literature(2018) Albayati, Abbas; Eyupoglu, Atilla Adnan; Cologlu, Harun; Bal, Nebil; Ertas, Nilgun Markal; 0000-0002-8605-9032; AAO-4286-2020Stewart-Treves syndrome (STS) is defined as angiosarcoma arising in the setting of chronic lymphedema. It is typically presented in breast cancer patients who underwent axillary dissection. A 79-year-old woman presented to our clinic with a wound that developed secondary to lymphedema. Pathologic examinations diagnosed the lesion as angiosarcoma. STS is a rare and deadly entity. It is hard to diagnose and has 10% mean survival rate for 5 years. We emphasize the importance of early diagnosis that can be a lifesaver.
