BACKGROUND: Bradykinin, a vasoactive peptide, has many biological functions. For example, it accelerates angiogenesis. Thus, we studied the effects of bradykinin on the survival of perforator flaps. METHODS: Averagely, 50 male Sprague-Dawley rats were divided into control and bradykinin groups and underwent procedures to the multiterritory perforator flap. Areas of flap survival were tested 7 days later. Flap perfusion was evaluated by laser Doppler imaging. We assessed the extent of autophagy by determining LC3-II/I, Beclin 1, and p62...

INTRODUCTION: Partial breast reconstruction (PBR) using chest wall perforator flaps (CWPF) allows for excision of tumors in the outer quadrant of the breast in women with small to moderate non-ptotic breasts resulting in a good aesthetic outcome. There are limited data available in the literature regarding long-term follow-up and the effect of CWPF on subsequent surveillance mammographic interpretation and recall rates. A retrospective audit with qualitative analysis of initial mammograms was performed to assess this...

BACKGROUND: We evaluated the use of laser speckle contrast imaging (LSCI) in the perioperative planning in reconstructive flap surgery. The aim of the study was to investigate whether LSCI can predict regions with a high risk of developing postoperative necrosis. Our hypothesis was that, perioperatively, such regions have perfusion values below a threshold value and show a negative perfusion trend. METHODS: A porcine flap model based on the cranial gluteal artery perforator was used...

The deep inferior epigastric artery perforator (DIEP) flap is one of the most used free flaps for the reconstruction of the breast after a mastectomy. Despite careful selection of the patients and preoperative imaging, difficulties in vascularization of the flap can occur in some cases. Although multiple vascular connections (bipedicled, turbocharged, or stacked) can be made in selected cases, there can still be venous congestion before the flap is transferred.Between 2016 and 2018, 4 cases in our series of 281 patients experienced such problems...

BACKGROUND:  To harvest any flap on the lateral circumflex femoral artery (LCFA) including tensor fasciae latae (TFL) muscle, a precise description of the vascular anatomy is required. There have been conflicting reports of the vascular supply of TFL and its overlying skin. The objective of this study was to evaluate the anatomy of the TFL muscle according to the location, origin, type, caliber, and length of vessels that supply the muscle. METHODS:  This study was performed on human cadavers ( n  = 16 thighs) that were injected with a mixture of lead oxide and gelatin through the femoral artery...

Background: In this study, we investigated the subdermal and perforator delay phenomena as a method to improve flap survival. Materials and Methods: In this experimental study, we used 24 rats in three groups. In the control group, the dorsal flaps were elevated and reinserted back to their place. In the experimental groups, we practiced the delay phenomena with two different techniques. In the first experimental group, cranial and lateral side incisions were performed; however, the flaps were not cut-off from the underlying fascia...

BACKGROUND: Necrosis of propeller flaps is a problem in clinical practice. This study was performed to investigate the effects of pedicle torsion on dynamic perforasome survival using a multiterritory perforator flap model in rats. METHODS: Intercostal artery perforator flaps (IC flaps) containing two adjacent dynamic perforasomes were applied to both sides of the dorsum in 15 rats. The IC vessels were dissected carefully under 10 × magnification. A 360° arc of pedicle torsion was applied to the right IC flaps, which comprised the rotary group...

Li-Ying Liao, Tzong-Shiun Li, Hung Chi Chen
In the past decades, numerous surgical techniques and conservative treatments for pilonidal sinus disease (PSD) had been discussed and published. There is still no consensus yet of the best techniques because of high recurrence rates and prolonged wound healing. In the case of complicated discharging sinus or recurrent PSD resistant to treatment with antibiotics, we recommend radical excision followed by a regional flap, which can obliterate the dead space with well-vascularised tissue. In this article, we presented the technique of snug suture fixation between the dermis and periosteum using a superior gluteal artery perforator (SGAP) flap...
