Background: Propeller flaps require torsion of the vascular pedicle of up to 180 degrees. Contrary to free flaps, where the relevance of an intact vascular pedicle has been documented, little is known regarding twisted pedicles of propeller flaps. As secondary surgeries requiring undermining of the flap are common in the extremities, knowledge regarding the necessity to protect the pedicle is relevant. The aim of this study was a long-term evaluation of the patency of vascular pedicle of propeller flaps...

BACKGROUND: The elbow is a challenging region to reconstruct functionally. Several closure methods for elbow wounds have been reported, including flap surgery. Here, we present the results obtained using a propeller flap pedicled by a posterior ulnar recurrence artery perforator (PURAP) or a radial collateral artery perforator (RCAP) for functional reconstruction of soft tissue defects in elbows. METHODS: Twenty-four patients with an average age of 27.0 years (range, 9-52 years) underwent elbow soft tissue reconstructions between 2005 and 2015...

INTRODUCTION: The posteromedial thigh (PMT) perforator flap is a valuable reconstructive option. In its pedicled form, the experience is currently limited to a few case reports. The purpose of this article is to describe various clinical applications of the pedicled posteromedial thigh (pPMT) flap for reconstruction of loco-regional soft tissue defects. PATIENTS AND METHODS: From 2014 to 2016, 15 patients underwent reconstruction with 15 pPMT flaps. The locations of the defects included the inguinal region (4 cases), the perineal and genital region (3 cases), the proximal and distal medial thigh (3 and 2 cases, respectively), and the popliteal fossa (3 cases)...

OBJECTIVE: This study was designed to investigate the clinical effects of adopting perforator pedicled propeller flap in the proper digital artery for treatment and sensory reconstruction of finger pulp defects in children. PATIENTS AND METHODS: Perforator pedicled propeller flap of proper digital arteries in thirty-one fingers from twenty-three children patients were selected for repairing the pulp defects on the 2nd to the 5th fingers. All cases were treated from September 2012 to December 2013...

BACKGROUND: Usually, anterolateral thigh (ALT) defects with width more than 8 cm cannot be closed directly. Although several methods of using local flaps exist, flap mobility of these methods is limited. We introduced a perforator-based propeller flap for such reconstruction. Their maximal mobility, which minimizes their size, is their greatest advantage. In addition, we present our technical refinements including double-axes propeller flap, the use of indocyanine green real-time angiography, and supercharged propeller flap for safer flap transfer...

BACKGROUND: Reconstruction of upper extremity deformities continues to be a challenge to the reconstructive surgeon. Various loco regional, distant and free flaps are available for reconstruction. However, each has its own set of advantages and disadvantages. Of the commonly performed local flaps, radial artery forearm flap, and the posterior interosseus artery flap stand out prominently. Recently, perforator propeller flaps have been used for resurfacing the upper extremity. The anterior interosseus artery perforator flap is an uncommonly used and described flap...

We present a new surgical modification to allow propeller perforator flaps to cover pressure sores at various locations. We used a propeller perforator flap concept based on the detection of newly formed perforator vessels located 1 cm from the wound margin and stimulated by the chronic inflammation process. Between January 2009 and January 2017, 33 wound edge-based propeller perforator flaps were used to cover pressure sores at various locations in 28 patients. In four cases more than one flap was used on the same patient...

REVIEW
Durga Karki, Rajeev B Ahuja
Contractures of the axilla and elbow can produce a significant impact on quality of life by reducing the ability to perform activities of daily living. Varieties of techniques are available for resurfacing defects following contracture release but graft or flap loss, donor-site morbidity, esthetics, and recurrences are still challenges for reconstructive surgeons. Central axis "propeller" flaps based on a random, subcutaneous pedicle were first described for axillary and elbow contractures to deploy the unburnt skin of axillary dome in type I and II contractures (Kurtzman and Stern) by moving them 90° to straddle the contracting bands...

BACKGROUND: The reconstruction of the posterior trunk, especially with large dead spaces, remains challenging. Regional muscle flaps may lack adequate volume and reach. The purpose of this report was to evaluate the efficacy of deepithelialized free-style perforator-based propeller flaps to obliterate defects with large dead space. METHODS: A total of 7 patients with defects on the posterior trunk with large dead spaces were evaluated. After complete debridement or resection, all flaps were designed on a single perforator adjacent to the defect, deepithelialized, and then rotated in a propeller fashion...

Honey bees (Apis mellifera) are remarkable fliers that regularly carry heavy loads of nectar and pollen, supported by a flight system - the wings, thorax and flight muscles - that one might assume is optimized for aerial locomotion. However, honey bees also use this system to perform other crucial tasks that are unrelated to flight. When ventilating the nest, bees grip the surface of the comb or nest entrance and fan their wings to drive airflow through the nest, and a similar wing-fanning behavior is used to disperse volatile pheromones from the Nasonov gland...

INTRODUCTION: The use of multiple small flaps linked in a "chain-linked" flap microanastomosed chimeric system is recommended in distal hand and digital defects reconstruction. The aim of this study is to demonstrates our experience utilizing microsurgical fabrication, multi-lobed and linking combined flaps for the reconstruction of hand degloving injuries with complex multidigit soft tissue defects. METHODS: Microanastomosed chimeric flap systems using ALT and DPA modified designed flaps were combined in five selections to cover extensive soft tissue defects involving the hands and multiple digits of 39 patients (M:F - 36:3) from October 2009 to February 2013...

Objective To describe the characteristics of the perforator vessel in the peroneal artery of the lower leg and to explore the use of perforator pedicle propeller flaps to repair soft tissue defects in the lower leg, heel and foot. Methods This retrospective study enrolled patients with soft tissue defects of the distal lower leg, heel and foot who underwent surgery using peroneal perforator-based propeller flaps. The peroneal artery perforators were identified preoperatively by colour duplex Doppler ultrasound...

Novel and combined tissue transfers from the lower extremity provide new tools to combat soft tissue defects of the hand, foot, and ankle, or fracture nonunion. Flaps can be designed for special purposes, such as providing a gliding bed for a grafted or repaired tendon or for thumb or finger reconstruction. Propeller flaps can cover soft tissue defects of the leg and foot. In repairing severe bone and soft tissue defects of the lower extremity, combined approaches, including external fixators, one-stage vascularized bone grafting, and skin or muscle flap coverage of the traumatized leg and foot, have become popular...

INTRODUCTION: In lower limbs, reliability of propeller perforator flaps (PPF) remains uncertain. The main complication is venous congestion, which can lead to distal necrosis. We aim to highlight if venous supercharging of PPF could substantially limit complications in lower limb coverage. METHODS: Between 2011 and 2016, we developed a standardized procedure of venous supercharging in the lower limb reconstruction with PPF using saphenous veins anastomosis. Then, we prospectively compared a consecutive series of 30 PPF to cover lower limbs defect, with a consecutive series of 30 venous-supercharged PPF (vsPPF)...

Niehls Kurniawan, Martin Keuchel
Flexible gastro-intestinal (GI) endoscopy is an integral diagnostic and therapeutic tool in clinical gastroenterology. High quality standards for safety, patients' comfort, and efficiency have already been achieved. Clinical challenges and technical approaches are discussed in this short review. Image enhanced endoscopy for further characterization of mucosal and vascular patterns includes dye-spray or virtual chromoendoscopy. For confocal laser endoscopy, endocytoscopy, and autofluorescence clinical value has not yet been finally evaluated...
