Propeller flap: Orthoplastic approach for coverage of distal leg and ankle defects

BackgroundCovering soft tissue defects of the distal one-third of the leg and the Achilles tendon region and is a challenging problem for an orthopedic surgeon. With recent advancements in the anatomical knowledge of perforating vessels, perforator-pedicled propeller flaps have become increasingly popular in recent decades. We aimed to evaluate the clinical outcomes of our patients whose soft tissue defects in the distal leg were reconstructed with propeller flaps and assessed association of complications with age, gender, flap size and arc of rotation.MethodsPatients that had a reconstruction with a propeller flap at the ankle from 2013 to 2019 were retrospectively reviewed. The main indications for the propeller flap were small- and medium-sized soft tissue defects of the distal lower limb. 20 propeller flaps were applied to 19 patients (14 male, 5 female) for various lower extremity defects.ResultsThe mean follow-up duration was 2 years (range, 6 months to 6 years). The average flap size was 82 cm² (range, 48–125 cm²). The flap was rotated 180 degrees in nine patients The source of the perforator vessel was the tibialis posterior artery in 14 cases, the peroneal artery in 4 cases, both the tibialis posterior and peroneal arteries in 1 case. Four complications (20 %) occured postoperatively. Two patients developed partial necrosis at the tip of the flap, and two patients developed superficial epidermolysis. No correlations were found between complications and flap size and the arc of rotation.ConclusionsThe propeller flap is a reliable option for reconstruction of small to moderate defects in the lower extremity with good clinical results and minimal donor-site morbidity. It is applicable for orthopedic surgeons who do not have microsurgical experience or an available microscope in the operating room.     

Reconstruction of elbow region defects using radial collateral artery perforator (RCAP)-based propeller flaps

Perforator-based propeller flaps permit flap rotation up to 180°. This ability to transfer skin from one longitudinal axis to another has led to the increasing use of perforator-based propeller flaps in extremity reconstruction, especially lower-extremity reconstruction. However, the application of perforator-based propeller flaps to upper-extremity reconstruction is still limited. This article reports two cases of successful reconstruction of elbow region defects with radial collateral artery perforator (RCAP)-based propeller flaps. The elbow region has a variety of perforators available for perforator-based propeller flap reconstruction. Among them, the RCAP seems to be one of the most reliable options. This is because there are less anatomical variations of perforators' location on the lateral upper arm than on the medial upper arm. By using an RCAP perforator as a flap pedicle, the small-to-medium sized defects (<6?cm in diameter) around elbow regions can be closed primarily without skin grafts.     

Reconstruction of soft tissue defects of the Achilles tendon with rotation flaps,pedicled propeller flaps and free perforator flaps

Introduction. Soft tissue defects exposing the Achilles tendon are challenging. Local perforator flaps represent a valuable option gaining increasing popularity. Despite preoperative planning an adequate perforator cannot always be found intraoperatively. The free peroneal artery perforator flap can serve as a back‐up option limiting the donor site morbidity to the same extremity without sacrificing major vessels or nerves. Methods. Nine patients with soft tissue defects exposing the Achilles tendon were treated with local perforator flaps, seven were scheduled for 180° propeller flap coverage after Doppler‐ultrasound examination. However, in two patients (22%) no adequate perforators were found intraoperatively. As the perforators for the free peroneal artery perforator flap were routinely mapped out, this flap was harvested for microsurgical reconstruction. Results. One patient with a 180° propeller flap developed a partial flap necrosis, another patient developed superficial epidermolysis, both requiring skingrafting. No complications were seen with free tissue transfer. Conclusion. Pedicled perforator flaps as propeller flaps add options to the armamentarium of microsurgeons. Despite thorough preoperative planning the surgeons must be prepared to perform a different method of reconstruction if inadequate vessels are encountered. To limit additional donor site morbidity, local options are preferred. The free peroneal artery perforator flap represents a good option as it matches the original tissue properties closely. The complication rate of propeller flaps in this series is tolerable. Propeller flaps should therefore be considered an alternative but not as a replacement of local fasciocutaneous flaps. © 2010 Wiley‐Liss, Inc. Microsurgery 30:608–613, 2010.     

Coverage of exposed bone and hardware of the medial malleolus with tibialis posterior artery perforator flap after ankle fracture surgery complications

Ankle fractures are among the most common orthopaedic surgical procedures. Skin‐related complications of these surgeries are difficult to reconstruct due to the inadequacy of soft tissue in the region. Although free flaps are generally considered as the first choice in reconstruction of this area, free flaps may not be a suitable option especially in patients with advanced age and comorbidities. Perforator flaps offer a fast and safe alternative in lower extremity reconstruction. In the literature, there are a limited number of studies using perforator flaps in managing the postoperative complications of the lower extremity trauma surgeries. In our study, we report our experience with reconstruction of soft‐tissue defects of medial malleolar region using posterior tibial artery perforator flap for postoperative complications of ankle fracture‐related surgeries.     

Free style perforator based propeller flaps: Simple solutions for upper extremity reconstruction!

Background:

The introduction of perforator flaps by Koshima et al. was met with much animosity in the plastic surgery fraternity. The safety concerns of these flaps following the intentional twist of the perforators have prevented widespread adoption of this technique. Use of perforator based propeller flaps in the lower extremity is gradually on the rise, but their use in upper extremity reconstruction is infrequently reported, especially in the Indian subcontinent.

Materials and Methods:

We present a retrospective series of 63 free style perforator flaps used for soft tissue reconstruction of the upper extremity from November 2008 to June 2013. Flaps were performed by a single surgeon for various locations and indications over the upper extremity. Patient demographics, surgical indication, defect features, complications and clinical outcome are evaluated and presented as an uncontrolled case series.

Results:

63 free style perforator based propeller flaps were used for soft tissue reconstruction of 62 patients for the upper extremity from November 2008 to June 2013. Of the 63 flaps, 31 flaps were performed for trauma, 30 for post burn sequel, and two for post snake bite defects. We encountered flap necrosis in 8 flaps, of which there was complete necrosis in 4 flaps, and partial necrosis in four flaps. Of these 8 flaps, 7 needed a secondary procedure, and one healed secondarily. Although we had a failure rate of 12-13%, most of our failures were in the early part of the series indicative of a learning curve associated with the flap.

Conclusion:

Free style perforator based propeller flaps are a reliable option for coverage of small to moderate sized defects.

Perforator Propeller Flap “Relay” for Distal Lower Extremity Soft Tissue Reconstruction

The peroneal artery perforator propeller flap is commonly used for distal lower extremity reconstruction; however, closure of the donor site defect can limit the utility of this flap. To overcome this limitation, we introduced a perforator propeller flap relay technique to reconstruct the donor-site defect. Between July 2015 and February 2019, the propeller flap relay technique was applied in 9 patients. In each case, a peroneal artery perforator propeller flap was transferred to repair a defect in the distal lower leg or the foot. In addition, a neighboring perforator propeller flap was transferred to close the donor-site defect. The peroneal artery perforator propeller flaps ranged from 14 × 4 to 29 × 8 cm² in size. Donor-site closure was accomplished using the relaying propeller flaps based on perforators from the peroneal, medial sural, and lateral sural arteries. Normal contour of the lower leg was preserved with acceptable scars. Additional time for the second flap procedure was less than 1 hour in each case. One peroneal artery perforator flap presented with partial flap necrosis. Other flaps survived completely without complication. Coverage of the donor-site defects of the peroneal artery perforator flaps can be achieved using various perforator propeller flaps. The perforator propeller flap relay technique allows surgeons to harvest a large peroneal artery perforator flap without being limited by significant donor-site morbidity. This technique can reconstruct defects at distal lower extremity with low morbidity and improved overall reconstructive results.     

Aesthetic Penoscrotal Resurfacing: Creating Propeller Flaps from Gluteal Folds

Background

Reconstruction of extensive penoscrotal defects is a surgical challenge. Resurfacing defects in highly complex three-dimensional structures and restoring their function are an essential part of the reconstruction of penoscrotal regions.

Internal mammary artery perforator flap for reconstruction of the chest wall

Abstract

We used internal mammary artery perforator (IMAP) flaps from the opposite side for reconstruction of small-to-medium-sized defects in the chest wall. The IMAP flaps were used in two patients who had unhealed, localised ulcers of the chest wall with exposure of the ribs after radical mastectomy. The lesion was excised widely, and the flap, based on a perforator vessel in the second or third intercostal space of the opposite chest wall, was raised. The flap was rotated from 90° to 180° along the vascular axis to the chest wall defect. The donor site was closed primarily. Both flaps showed stable postoperative circulation and survived completely. Defects of the chest wall could be covered with healthy, well-vascularised tissue on one perforator without deep infection. The IMAP flap is a reliable and less invasive option to be considered for medial, localised, reconstruction of the chest wall.     

One-stage reconstruction of extensive composite extremity defects with low donor site morbidity: A retrospective case series of combined transfer of a vascularized fibula flap and a perforator flap

BackgroundExtensive composite extremity defects remain a challenge in plastic and reconstructive surgery. To preserve the extremity, we used combined transfer composed of the vascularized fibula flap and a perforator flap from various body parts to reconstruct extensive composite extremity defects.Patients and methodsFrom January 2004 to December 2018, 14 male patients aged 9 to 55 years with extensive composite extremity defects (large soft-tissue and long bone defect) underwent reconstructive surgery in our institution. The combined transfer surgery consisted of the vascularized fibula bone flap and a perforator flap, such as anterolateral thigh flap, deep inferior epigastric perforator flap, or thoracodorsal artery perforator flap.ResultsAll fourteen patients were treated successfully using the combined transfer method. The dimensions of the different perforator flaps ranged from 13 × 6 cm² to 26 × 11 cm², and the size of the skin paddle of the fibular osteocutaneous flap ranged from 9 × 3 cm² to 21 × 7 cm². The median length of the fibular graft was 15 cm. No serious donor site complications were observed. Only one patient developed venous congestion and was salvaged. Another patient had hematoma at the recipient site and underwent debridement. Though all patients achieved bone union (median time of 8 months), two developed a stress fracture of the transferred free fibula.ConclusionWe were able to minimize donor site morbidity and avoid amputation in these patients using the combined transfer technique Our results show that the combined transfer of perforator flap and vascularized fibula flap with or without a skin paddle is a feasible reconstruction option for the treatment of the extensive composite extremity defects.     

Combined multi-lobed flaps: A series of 39 extensive hand and multi-digit injuries one-staged reconstructions using modified designs of ALT,DPA and chimeric linking flaps

IntroductionThe 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.MethodsMicroanastomosed 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. Five different microsurgical combined chimeric flap systems utilised in extensive hand and multidigit injuries; innervated ALT flaps, multilobed DPA flaps, innervated ALT flap with multilobed DPA flap, innervated ALT flap with sensate ALT flap and bilobed ALT flap with multilobed DPA flap. All DPA donor sites were reconstructed using free ALT flap and anterior tibial artery propeller flap.ResultsThirty-nine combined free flap extremities reconstructions on 39 patients (M:F − 36:3) with average age 28.5 (18–45) years sustained traumatic degloving injuries, 24 from road traffic accidents and 15 from industrial devices. Five different designs of combined multi-lobed flaps have be successfully used without any peri-operative complications. Average follow-up of 12 months, all flaps survived without complications. Operated extremities showed favorable functional recovery with restoration of the diminished protective sensation on the flap through reinnervation. All flaps survived uneventfully with coverage matching the texture and color of the recipients. Donor sites healed without complication.ConclusionThe microsurgical fabrication of chimeric ALT flaps and multilobed DPA flaps is a valuable alternative for the reconstruction of hand degloving injury with complex multidigit soft tissue defects.Level of evidence: Level IV, therapeutic study.     

Comparison of the outcomes of adipofascial and two–staged fasciocutaneous reverse sural flap in patients with lower leg trauma

BackgroundDistal one – third trauma of the lower limb is a complex condition to treat. The reverse sural flap is a time tested procedure for reconstruction of such defects especially in patients where free flaps are ruled out due to comorbidities. The purpose of this study is to compare the two modifications of the classical technique of reverse sural flap (adipofascial and fasciocutaneous) which is lacking in the literature.Material & methodsIn this study, the authors conducted a retrospective analysis of 67 patients with lower one-third leg defects reconstructed with either adipofascial reverse sural flap (Group A, n = 37) or two-staged fasciocutaneous reverse sural flap (Group B, n = 30) in a tertiary care hospital in North India between 2015 and 2019. An evaluation of the different flap characteristics of the two variants of the reverse sural flap was done and compared. Mean follow up period was 12 months.ResultsThe adipofascial group showed shorter operative time, was a single-stage and with better reach and aesthetic outcome. The complications did not differ except that for the adipofascial group was associated with unstable skin graft over the flap initially which did not require any treatment.DiscussionLower one-third defect of the lower limb has been a challenge for reconstructive surgeons all over the world. The goal of reconstruction is a functional lower limb. Although free tissue transfer is the preferred modality of treatment of such cases but it may not be possible in all cases due to various reasons. Reverse sural flap is a very lucrative local option for such reconstructions as it is easy to perform, reliable, low profile and bulk, require minimal facilities with less operative time. Adipofascial flaps represent an extremely useful modification of the reverse sural flap which is quick to perform with minimal donor site morbidity.ConclusionAdipofascial reverse sural artery flap is a good option for patients with lower limb trauma with the added advantage of being single-stage and with better donor site cosmesis as compared to the fasciocutaneous reverse sural artery flap.

Propeller TAP flap: Is it usable for breast reconstruction?

Abstract

The aim of this study was to examine if a propeller thoracodorsal artery perforator (TAP) flap can be used for breast reconstruction. Fifteen women were reconstructed using a propeller TAP flap, an implant, and an ADM. Preoperative colour Doppler ultrasonography was used for patient selection to identify the dominant perforator in all cases. A total of 16 TAP flaps were performed; 12 flaps were based on one perforator and four were based on two. A permanent silicone implant was used in 14 cases and an expander implant in two. Minor complications were registered in three patients. Two cases had major complications needing additional surgery. One flap was lost due to a vascular problem. Breast reconstruction can be performed by a propeller TAP flap without cutting the descending branch of the thoracodorsal vessels. However, the authors would recommend that a small cuff of muscle is left around the perforator to ensure a sufficient venous return.

Waveform-arranged multiple skin paddles: A novel design to reconstruct complex soft tissue defects of the extremities with a modified multi-lobed perforator flap

BackgroundMulti-lobed perforator flap was one of popular approaches for one-stage reconstruction of complex soft tissue defects because of its minimal donor-site morbidity. However, the area of skin island that can be harvested on the donor site is limited on the angiosome distribution, Moreover, large defects require more than the conventional skin island provided by a traditional multi-lobed perforator flap. For further extended skin paddles, this study presented a novel design of waveform-arranged skin paddles to elevated a modified multi-lobed perforator flap for the reconstruction of complex soft tissue defects in the extremities.MethodsFrom March of 2015 to March of 2020, fifteen patients underwent complex soft tissue defects reconstruction with waveform-arranged multi-lobed perforator flaps. According the size, shape and localization of the defects, two strategies were performed to design this modified multi-lobed flap.ResultsA total of fifteen waveform-arranged multi-lobed perforator flaps were successfully harvested to reconstruct complex soft tissue defects of the extremities. Among of them, Waveform–arranged dual skin paddles perforator flap were performed in eleven cases, and the waveform–arranged tripaddle perforator flaps were used in four cases. All the flaps survived and no flap related complication was observed postoperatively. The donor sites were closed directly in all cases. The mean follow-up time was 15.6 months. Most of the cases showed satisfactory contour.ConclusionThe waveform design of multi-lobed perforator flap was an alternative approach for reconstruction of complex soft tissue defects; it can maximize the harvested skin area of the donor site to provide extended skin island.     

Lumbar artery perforators: an anatomical study based on computed tomographic angiography imaging

Background: The free lumbar artery perforator flap has recently been introduced as a potentially valuable option for autologous breast reconstruction in a subset of patients. Up to date, few anatomical studies, exploring the lumbar region as a donor site for perforator- based flaps, have been conducted.

Methods: An anatomical study of the position of the dominant lumbar artery perforator was performed, using the preoperative computed tomographic angiography images of 24 autologous breast reconstruction patients. In total, 61 dominant perforators were determined, 28 on the left and 33 on the right side. A radiologist defined the position of the perforator as coordinates in an xy-grid.

Results: Dominant perforators were shown to originate from the lumbar arteries at the level of lumbar vertebrae three or four. Remarkably, approximately 85% of these lumbar artery perforators enter the skin at 7–10?cm lateral from the midline (mean left 8.6?cm, right 8.2?cm).

Conclusion: This study concludes a rather constant position of the dominant perforator. Therefore, preoperative-computed tomographic angiography is not always essential to find this perforator and Doppler ultrasound could be considered as an alternative, thereby carefully assessing all advantages and disadvantages inherent to either of these imaging methods.     

Use of dorsal intercostal artery perforator flap in the repair of back defects

Background: The dorsal intercostal artery perforator (DICAP) flap is a well-vascularised flap that is elevated above the dorsal branch of the vertebral segments of the posterior intercostal artery. The aim of this study was to repair back defects using DICAP flaps.

Materials and methods: Eight patients who had undergone reconstruction with DICAP flaps for defects located on the back of the torso due to conditions of various aetiologies between 2011–2014 were included in this study. Patient age and gender, aetiology of the condition, dimensions of the defect and the flap, site of the defect, and postoperative complications were recorded.

Results: Three females and five males were included in this study. The age of the patients ranged between 19–71 years (mean?=?53.6 years). The aetiology was skin tumour in five patients and pressure wound, gunshot injury, and plate screw exposition subsequent to spinal surgery in one patient each. The sites of the defects were successfully closed in all patients, and no flap loss was observed in any patient.

Conclusions: DICAP flaps have some advantages compared to conventional muscle and muscle skin flaps, such as greater protection of muscle functions, less invasiveness, and lower donor site morbidity. This flap has a high mobilisation capacity due to its elevation above nine bilateral perforator arteries. Therefore, the DICAP flap is useful for the repair of median and paramedian back defects. Based on its advantages, it is suggested that the DICAP flap should be considered as a useful option for the repair of back defects.     

Contralateral unaffected breast augmentation using zone IV as a SIEA flap during unilateral DIEP flap breast reconstruction

BackgroundContralateral breast augmentation during unilateral breast reconstruction is a good option for women with small breasts. In patients with adequate lower abdominal tissues, the deep inferior epigastric perforator (DIEP) flap is often the first choice for unilateral autologous breast reconstruction. We use Zone IV, which is usually excised owing to its insufficient blood circulation, as a superficial inferior epigastric artery (SIEA) flap for contralateral breast augmentation.MethodsBetween October 2004 and January 2016, 32 patients underwent unilateral breast reconstruction using a DIEP flap and an attempted simultaneous contralateral breast augmentation with an SIEA flap. The unilateral DIEP flap attached to the contralateral SIEA flap was split into two separate flaps after indocyanine green angiography. In all patients, ipsilateral internal mammary vessels were used as recipient vessels for DIEP flap breast reconstruction. The SIEA flap pedicle was anastomosed to several branches of the deep inferior epigastric vessels. The SIEA flap was inset beneath the contralateral breast through the midline.ResultsOf 32 patients, 27 underwent DIEP flap breast reconstruction and simultaneous unaffected breast augmentation using 25 SIEA or 2 superficial circumflex iliac artery perforator (SCIP) flaps. All DIEP flaps survived, and total necrosis occurred in one SIEA flap. The mean weight of the final inset for DIEP flap reconstruction and SIEA or SCIP flap augmentation was 416 g and 112 g, respectively.ConclusionsUnilateral DIEP flap breast reconstruction and contralateral SIEA flap breast augmentation may be safely performed with satisfactory results.     

Propeller DICAP flap for a large defect on the back—Case report and review of the literature

Reconstruction of large soft tissue defects of the back is a challenging problem. Large defects of the back were reconstructed with multiple random pattern or local pedicled muscle (and skin graft) or musculocutaneous flaps. The clinical use of perforator flaps has demonstrated that harvesting of flaps on a single perforator is possible for reconstruction of large defects. We present a 71‐year‐old male with a lesion on his left mid back that measured 10 × 10 × 4 cm³. Biopsy of the lesion was consistent with dermatofibrosarcoma protruberans. Wide local excision of the lesion with 4 cm margin was performed. The soft tissue defect, ～20 cm in diameter, was reconstructed with a large propeller dorsal intercostal artery perforator (DICAP) flap. The DICAP flap measured 40 × 15 cm² based on a single perforator—lateral branch of dorsal rami of the seventh posterior intercostal artery on the right side. The perforator flap was elevated at the subfascial level and transposed 180° into the defect. The donor site on the right side of the back was closed directly. This case illustrates the size of the propeller DICAP flap that could be safely harvested on a single perforator from the dorsal rami of the posterior intercostal artery. To our knowledge this is the largest reported pedicled perforator flap harvested on a single perforator on the posterior trunk. © 2012 Wiley Periodicals, Inc. Microsurgery, 2012.
