Resurfacing of multiple adjacent defects with free multipaddle SCIAP flaps.

BACKGROUND: The efficient resurfacing of multiple adjacent defects (MADs) requires precise reconstructive strategy. Various approaches (e.g., several flap transferring or prelamination of the recipient site) have been reported, but recipient-site impairments, pain, long hospitalization, and low cost-benefit results fatefully considered them as compromise approaches. This study aims to evaluate the feasibility of MADs reconstruction with free multipaddle superficial circumflex iliac artery perforator (SCIAP) flaps. METHODS: From Dec 2015 to Dec 2020, we enrolled patients with upper and lower extremity defects treated with various multipaddle SCIAP flaps (2-paddle, 3-paddle, and 4-paddle). Patient demographics and outcomes of each group were collected. RESULTS: Thirty-two, 21, and 6 patients underwent 2-paddle, 3-paddle, and 4-paddle SCIAP flaps transfers, respectively. All multipaddle SCIAP flaps survived without vascular problems, and the donor sites were closed directly. Except for 3 cases of 2-paddle SCIAP flaps drained by superficial circumflex iliac vein venous return, most cases (n = 56) were drained by venae comitans. Minor complications, including partial flap necrosis (4 cases) and lateral femoral cutaneous nerve palsies (11 cases), were treated conservatively. All patients were satisfied with the reconstructive outcome. CONCLUSION: Multiple adjacent defects reconstruction is still a Gordian knot and lacks a golden standard. The free multipaddle SCIAP flap was demonstrated as a promising alternative, not only enriching its versatility but also initially highlighting the "replace need with need" reconstructive demand.

Recent Advances in Upper Extremity Microsurgery: From Traditional to Perforator Flaps.

The upper extremity has unique functional and aesthetic requirements. Reconstruction of upper extremity soft tissue defects should ideally provide coverage for vital structures, facilitate early mobilization, be thin and pliable to match its slim contour, and reestablish sensation. Perforator flaps can be raised on the superficial fascia, which creates a thin and pliable yet durable and supple flap option to match the contour and functional needs of the upper extremity. Comparisons to traditional reconstructive methods should be performed to assess whether these innovations in microsurgical reconstruction of upper extremity defects provide an improved functional and aesthetic benefit over traditional methods.

Day microsurgery: Further application of free flap transfer as an ambulatory surgery.

BACKGROUND: Free flap transfer (FFT) is essential in soft tissue reconstruction and can be done under local anesthesia. However, there is no study evaluating the feasibility of FFT without hospitalization. This study evaluated the feasibility of day microsurgery-FFT as a day surgery without hospitalization. METHODS: Patients who underwent day microsurgery were included. The FFT was performed under local infiltration and/or block anesthesia without sedation by a surgeon with enough experience in supermicrosurgery. We focused on minimal dissection and secure hemostasis to prevent possible complications. Patient characteristics, operative findings, and postoperative course were evaluated. RESULTS: Seventeen patients with a mean age of 40.4 years were included. All defects were of the upper extremity and due to trauma. Utilized anesthesia included local infiltration in 11 sites, digital block in 10 sites, wrist block in 12 sites, and elbow block in 4 sites. Used flap included superficial circumflex iliac artery perforator flap in 8 (47.1%) cases and short-pedicle partial toe flaps in 9 (52.9%) cases. The mean diameters of the anastomosed artery/vein were 0.88/1.29 mm, and the mean operation time was 68.9 min. All transferred flaps survived without total or partial necrosis. The postoperative course was uneventful except for 1 (5.9%) case with minor wound dehiscence. CONCLUSIONS: FFT could safely be performed without hospitalization in selected cases of an upper extremity defect. Supermicrosurgery and careful patient selection play an important role in safe day microsurgery.

Extremity reconstruction with superficial circumflex iliac artery perforator free flap: Refinements and innovations after 101 cases.

INTRODUCTION: The superficial circumflex iliac artery perforator flap is based on perforators originated on the superficial circumflex iliac artery. This flap is thin and pliable, of moderate size, and has a concealed donor site. The authors report their experience, innovations, and refinements in both planning and execution, and the outcomes obtained after 101 extremity reconstruction consecutive cases. PATIENTS AND METHODS: A total of 101 superficial circumflex iliac artery perforator flaps were prospectively reviewed and followed up for at least one year at Hospital del Trabajador. The flaps were used for both upper (n = 21) and lower limbs (n = 80), planned with computed tomography angiography/augmented reality, and raised above the superficial fascia using a standardized approach. Demographic data, anatomy of the flap, surgical technique, and the results were assessed. RESULTS: Average flap size was 90.5 cm2, ranging from 25 to 212 cm2. Total flap loss occurred in 6 flaps (5.9%). Four patients developed complications at the donor site. Debulking surgery was performed in 7 patients (6.9%). The average follow-up period was 850 days (range, 370-1405 days). CONCLUSIONS: The superficial circumflex iliac artery perforator flap is versatile, thin, and pliable, suitable for covering even large defects in either the upper or lower extremities, obtaining a shallow contour and optimal esthetics results. The elevation can be standardized, but requires training and proper planning. This is the largest series in a Western country reporting the experience, refinements, and innovation that allows for better results in limb reconstruction.

The Use of the Deep Brachial Artery as the Recipient Artery for Free Perforator Flap Transfer: An Anatomic Study and Clinical Applications.

Background and Objectives: Soft tissue reconstruction after sarcoma ablation in the posterior aspect of the upper arm has been commonly addressed using the pedicled latissimus dorsi musculo-cutaneous flap. The use of a free flap for coverage of this region has not been reported in detail. The goal of this study was to characterize the anatomical configuration of the deep brachial artery in the posterior upper arm and assess its clinical utility as a recipient artery for free-flap transfers. Materials and Methods: In total, 18 upper arms from 9 cadavers were used for anatomical study to identify the deep brachial artery's origin and point of crossing the x-axis, which was set from the acromion to the medial epicondyle of the humerus. Measurements of the diameter were taken at each point. The anatomic findings of the deep brachial artery were employed clinically in the reconstruction of the posterior upper arm after sarcoma resection using free flaps in 6 patients. Results: The deep brachial artery was found in all specimens between the long head and the lateral head of the triceps brachii muscle, and it crossed the x-axis at an average distance of 13.2 ± 2.9 cm from the acromion, with an average diameter of 1.9 ± 0.49 mm. In all 6 clinical cases, the superficial circumflex iliac perforator flap was transferred to cover the defect. The average size of the recipient artery, the deep brachial artery, was 1.8 mm (range, from 1.2 to 2.0 mm). The average diameter of the pedicle artery, the superficial circumflex iliac artery, was 1.5 mm (range, from 1.2 to 1.8 mm). All flaps survived completely with no postoperative complications. Conclusions: The deep brachial artery can be a reliable recipient artery in free-flap transfers for posterior upper arm reconstruction, given its anatomical consistency and sufficient diameter.

Repair of multiple hand defects with superficial circumflex iliac artery perforator flap.

BACKGROUND: Reconstruction and repair of multiple defects in the hand is a combination of function, sensation and aesthetics. The reconstruction using the superficial circumflex iliac artery perforator flap has become popular, which overcomes the inherent shortcomings of traditional inguinal flaps by preserving the deep fascia. In this report, we present our experience in the design and clinical application of the superficial circumflex iliac artery perforator flap, which we used to repair multiple defects in the hand. METHODS: From January 2015 to December 2020, 41 patients received free superficial circumflex iliac artery perforator flap to repair multiple hand defects. All flaps were carefully designed according to the hand defect including 21 single and 20 bilobed flaps. The area of ​​the donor area is 2.5 cm × 3.0cm∼8.0 cm × 6.5 cm. We followed up all patients regularly and completed standardized assessments of outcomes based on post-reconstruction hand function and esthetic scores. RESULTS: 41 cases of flaps survived completely.3 cases of vascular crisis was relieved after surgical exploration, 1 case of mild distal necrosis was healed after dressing change, 1 case of pigmentation happened. There were 41 patients, 27 males and 14 females, with an average age of 40.5 years (4 to 59 years old). The defects included 20 cases opisthenars and 21 cases palms. The wounds were irregular, with exposed or damaged tendons, nerves or bones. All flaps were followed for a mean of 10.5 months (3 to 15 months). The functional and esthetic outcomes were satisfactory for all flaps without complications such as hand spasms, adhesions and scar contractures CONCLUSION: The superficial circumflex iliac artery perforator flap's donor site was concealed, relatively stable perforators, easy dissection. Recipient site condition was good and acceptable for the patients. It is a significant choice for multiple hand defects.

Novel application and evaluation of superficial circumflex iliac artery perforator flap / 中华显微外科杂志

Objective:Verstaile free superficial circumflex iliac artery perforator flap(SCIAPF) were adopted for various reconstructive scenarios, and its clinical effect and value was evaluated.Methods:Retrospective analysis was performed on 42 patients with tissue defects admitted in the Department of Orthopeadic of the Second Affiliated Hospital of Wenzhou Medical University from January 2015 to May 2019. Nine patients had injury in the foot, 8 in ankle, 8 in calf, 7 in forearm, 9 in hand, and 1 in the mouth. All of the defects were repaired by SCIAPF, including 28 single soft tissue defect wounds, 8 multiple soft tissue defect, and 6 composite defects. The size of soft tissue defect were 1.2 cm×1.8 cm-14.0 cm×20.8 cm. The size of flaps were 1.5 cm×2.0 cm-15.3 cm×22.3 cm. The patients entered follow up by outpatient clinic visit and telephone reviews to observe the survival of the flaps, functional recovery and complications.Results:In this series, there were 28 flaps, including 18 pedicled with superficia branch of superficial circumflex iliac artery, 2 pedicled with deep branch of superficial circumflex iliac artery, and 8 pedicled with 2 branches. Six were chimeric flaps. Among them, 4 flaps were iliac bone flaps with superficial branch of superficial circumflex iliac artery flaps, and 2 were superficial iliac circumflex artery flap with sartorius muscle flap. Eight cases were resurfaced with lobulated SCIAPF. Arterial anastomoses: end-to-side in 35 arteries and end-to-end in 7 arteries. Venous anastomosis: end-to-end in 27 veins and end-to-side in 15 veins. Venous return through superficial iliac circumflex vein in 25 flaps, through venae comitantes in 12 flaps and through both in 5 flaps. All flap donor sites were sutured directly. All flaps survived uneventfully except for one that compromised with end-to-side anastomotic dehiscence and bleeding, and survived after re-anastomosis. All flaps and donor sites healed primarily. During the follow-up of 6-24(mean, 11.5) months, the pliable flaps were ruddy in colour and soft in texture, without obvious bloatness and pigmentation. The donor site healed well with linear scars in 35 cases and mild scar hyperplasia in 7 cases. The donor hip function were normal. Three patients suffered a numbness of the thigh caused by intraoperative injury lateral femoral cutaneous nerve and it disappeared completely after 3 months.Conclusion:New applications of lobulated or chimeric SCIAPF, based on the SCIA vasculature or its branches, can meet most of the clinical repair requirement.

Deep Fat Saving Elevation of the Superficial Circumflex Iliac Artery Perforator Flap.

Background and Objectives: Prolonged drain stay and lymphorrhea are often problems at the donor site of the superficial circumflex iliac artery perforator (SCIP) flap. This study aimed to introduce a novel technique of the SCIP flap elevation: Deep Fat Saving (DFS) technique. Materials and Methods: Thirty-two patients who underwent the SCIP flap transfer were divided based on the flap-elevated layer: above the deep fascia or the Camper fascia saving the deep fat. The duration of drain stay and the rates of flap survival and donor-site complications were compared between the groups. The inverse probability weighting (IPW) method was conducted to balance confounders. Results: By IPW, two balanced pseudo-populations were created: DFS = 33.9 and Conventional = 31.3. There were no significant differences in the rate of flap survival (DFS: 100% verses Conventional: 95.8%, p = 0.32) and donor site complications (DFS: 2.4% versus Conventional: 1.3%, p = 0.68, respectively). The duration of drain stay was shorter in the DFS group (weighted median: 6 versus 8 days; weighted difference: -1.6 days (95% confidence interval: -2.8 to -0.4), p = 0.01). Conclusions: An SCIP flap can be reliably harvested using the Deep Fat Saving technique.

Soft Tissue Defect Reconstruction and Lymphatic Complications Prevention: The Lymphatic Flow-Through (LyFT) Concept.

Background and Objectives: When a lymphatic-rich area is severely damaged, either after trauma or a surgical procedure, both soft tissue defect reconstruction and lymphatic drainage restoration are necessary. In this setting, we aim to show the potential of the lymphatic flow-through flap (LyFT) concept, which might be an attractive new solution to reduce postoperative lymphatic complications. Materials and Methods: Between 2018 and 2021, 12 patients presenting a soft tissue defect involving damage to the lymphatic drainage pathway received a lymphatic flow-through flap for volume and lymphatic drainage restoration. Different flaps were employed: 3 pedicled superficial circumflex iliac artery perforator (SCIP) flaps, 2 free SCIP flaps, 3 pedicled deep inferior epigastric perforator (DIEP) flaps, 2 pedicled vertical posteromedial thigh (vPMT) flaps, and 2 pedicled anterolateral thigh (ALT) flaps. A range of 1 to 3 lymphovenous anastomosis (LVA) with flap's veins was performed (mean 1.9). For a better dead space obliteration, an additional vastus lateralis muscle flap was performed in one case. Indocyanine green (ICG) lymphography was used in all cases to identify the lymphatic pathway, make the preoperative markings, and check the patency of the anastomoses. Results: In all cases, the reconstructive results were satisfactory from both the functional and aesthetic points of view. No secondary surgeries were required, and only one minor complication was encountered: an infected seroma that was managed conservatively. The mean follow-up was 9.9 months (range 6-14 months). Conclusions: Lymphatic flow-through flaps seem to effectively reduce the risk of lymphatic complications after the reconstruction of soft tissue defects with a compromised lymph pathway. This is a versatile solution that might be used in different body regions resorting to different flap types.

Simultaneous Lymphatic Superficial Circumflex Iliac Artery Perforator Flap Transfer from the Zone 4 Region in Autologous Breast Reconstruction Using the Deep Inferior Epigastric Artery Perforator Flap: A Proof-of-Concept Study.

The incidence of upper extremity lymphedema after breast cancer treatment is reported to be 14% after axillary lymph node dissection (ALND) and 33% after ALND and regional lymph node dissection. The present report describes a novel method in which the afferent lymphatic vessels are harvested with their lymph nodes from the Zone 4 region as a separate flap, the superficial circumflex iliac artery perforator (SCIP) flap, in the setting of autologous breast reconstruction using the deep inferior epigastric artery perforator (DIEP) flap. From September 2017 to September 2020, seven female patients with an average age of 46.9 years (range: 39 to 54 years) underwent autologous breast reconstruction using the DIEP flap and the lymphatic SCIP flap procured separately from the Zone 4 region. All patients had undergone ALND, four patients had undergone radiation therapy, and three patients had established lymphedema at the time of reconstruction. All lymphatic SCIP flaps survived completely. Lymphedema did not occur in any of the four patients to whom the lymphatic flap was transferred for a preventive purpose (average follow-up: 37.5 months). In three patients with established lymphedema at the time of reconstruction, the average rate of estimated volume decrease at the last follow-up (average: 29.0 months) was 12.6%. A lymphatic SCIP flap procured from the Zone 4 region in DIEP flap breast reconstruction can contribute to improvement or prevention of lymphedema with no additional donor site.

Case Report: Superficial Circumflex Iliac Artery Perforator Flap for Tongue Reconstruction Following the Hemiglossectomy.

Objective: Therapeutic evaluation of applying superficial circumflex iliac artery perforator (SCIP) flap in tongue reconstruction after hemiglossectomy. Methods: We retrospectively collected a total number of 14 patients who received SCIP flap reconstruction for tongue defects at the Fujian Medical University affiliated Union Hospital, between November 2016 and November 2020. We evaluated the clinical features of the flap, analyzed the postoperative functions and esthetic effects after 6 months of the tongue reconstruction. Results: All the SCIP flaps survived successfully after the operation, the recipient site tongue bodies were well reconstructed 6 months after the surgery. Patient speech and swallowing functions were well recovered during the follow-up. The scars in the donor site were concealed with limited numbness. Conclusions: With the advantages of the hidden donor site and aesthetic benefits, the SCIP flap is a reliable option for the reconstruction of the tongue defect after hemiglossectomy.

Do-It-Yourself Preoperative High-Resolution Ultrasound-Guided Flap Design of the Superficial Circumflex Iliac Artery Perforator Flap (SCIP).

The superficial circumflex iliac artery perforator (SCIP) flap is a well-documented, thin, free tissue flap with a minimal donor site morbidity, and has the potential to become the new method for resurfacing moderate-size skin defects. The aim of this study is to describe an easy, reliable, systematic, and standardized approach for preoperative SCIP flap design and perforator characterization, using color-coded duplex sonography (CCDS). A list of customized settings and a straightforward algorithm are presented, which are easily applied by an operator with minimal experience. Specific settings for SCIP flap perforator evaluation were investigated and tested on 12 patients. Deep and superficial superficial circumflex iliac artery (SCIA) branches, along with their corresponding perforators and cutaneous veins, were marked individually with a permanent marker and the anatomy was verified intraoperatively. From this, a simplified procedure for preoperative flap design of the SCIP flap was developed. Branches could be localized and evaluated in all patients. A preoperative structured procedure for ultrasonically guided flap design of the SCIP flap is described. A 100% correlation between the number and emergence points of the branches detected by preoperative CCDS mapping and the intraoperative anatomy was found.

Use of the superficial circumflex iliac artery perforator flap for reconstruction after sarcoma resection.

BACKGROUND: Postoperative complications after flap-coverage in sarcoma treatment can postpone postoperative adjunct treatments. Here, we present our experience with the use of the superficial circumflex iliac artery perforator (SCIP) flap after sarcoma resection. PATIENTS AND METHODS: Patients undergoing immediate reconstruction surgery with a flap after sarcoma resection at a single institution from February 2017 to April 2020 were identified. Patient demographics, tumor characteristics, surgical characteristics, and complications were examined. RESULTS: Thirty-five consecutive patients underwent reconstructions using a SCIP flap (34 free and one pedicled SCIP flaps). We also identified 47 consecutive patients who underwent reconstruction with other pedicled or free flaps over the same time period. No significant differences were found in patient age, gender, defect size, or operative time between these two groups. The incidences of overall complications (20/47 [42.6%] vs. 3/35 [8.5%], p < .001), flap dehiscence (7/47 [14.8%] vs. 0/35 [0%], p = .018), and total flap complications (15/47 [31.9%] vs. 2/35 [5.7%], p = .005) were statistically greater in the control group than in the SCIP group. CONCLUSION: With its minimal postoperative complication rate both in the reconstruction site and the donor site, the SCIP flap can be considered an optimal reconstruction option after sarcoma resection.

The anatomical reliability of the superficial circumflex iliac artery perforator (SCIP) flap.

INTRODUCTION: In order to achieve a satisfactory functional and aesthetic result a thin skin flap is often required in surgical reconstruction of various body regions. Perforator flaps based on either the superficial or deep branch of the superficial circumflex iliac artery (SCIA) have been used for this purpose mainly in the Asian population. Recently the superficial plane has been established as a new way of elevating the flap. Anatomical studies and details of this new flap are lacking. MATERIAL AND METHODS: Wide areas were harvested subfascially from the groin of Thiel-fixated cadavers. Both deep and superficial branches of the superficial circumflex iliac artery were carefully dissected and individually injected with µAngiofil. After CT-imaging the flaps were raised on the superficial plane, perforators were marked and the flaps subsequently rescanned. High-resolution images of regions of interest were taken using micro-CT. RESULTS: A total of 21 flaps were harvested and analyzed. Both the deep and superficial branch provided more than three perforators per branch, however, the deep branch based flap was significantly larger (202 vs. 112 cm2, p < 0.01) and had a longer pedicle (9.1 vs. 6.6 cm, p < 0.01). Raising the flap in the superficial plane reliably reduces bulk and increases homogeneity. CONCLUSIONS: The SCIP flap appears to have a reliable vascular blood supply. The SCIA and its main branches and perforators have a consistent vascular pattern. The deep branch of the SCIA has the anatomic potential to be the preferred pedicle in case larger flaps with longer pedicles are necessary.

Application of arterial end-to-end and end-to-side anastomosis in superficial branch of the superficial circumflex iliac artery perforator flap transfer / 中华显微外科杂志

Objective:To explore a comparative study of arterial end-to-end and end-to-side anastomosis in superficial branch of the superficial circumflex iliac artery(SCIA) perforator flap transfer.Methods:Between November, 2019 and December, 2020, 21 patients with the soft tissue defects in the limbs were repaired with superficial branch of the SCIA perforator flaps. The size of flaps ranged from 3.5 cm×7.0 cm to 9.0 cm×18.0 cm. According to the upper or anterior wall of the main artery in the recipient area having branches that matched the flap artery, 2 groups were established. End-to-end group: 10 cases were anastomosed end-to-end between the flap artery and branch of the main artery in the recipient area; End-to-side group: 11 cases were anastomosed end-to-side between the flap artery and side mouth of the main artery in the recipient area. The vein of flap was anastomosed end-to-end with the accompanying vein to the main artery in the recipient area. All of the donor sites were sutured directly. All patients were followed-up for 6-12 months and the survival of the perforator flap, the appearance and function of the perforator flap and the donor site were observed. All data of the 2 groups were conducted statistical analyzed. P<0.05 was statistically significant. Results:All 10 flaps in end-to-end group survived successfully. In end-to-side group, 2 cases had venous crisis in 11 cases of flaps,the exploration revealed venous thrombosis, and the arterial end-to-side anastomosis had smooth blood flow had embolism. One flap survived after re-anastomosis of the vein, and 1 flap was changed to a pedicled abdominal flap during the re-venous crisis. The postoperative follow-up was 6 months to 1 year. The appearance and function of the flap and donor site were satisfactory, without difference between the 2 groups. The SCIA superficial branch artery caliber, recipient artery branch or lateral caliber was not statistically different between the 2 groups( P>0.05). The time of anastomosis for end-to-end group was[(16.70±1.34) min]. It was lower than that of anastomosed end-to-side group[(23.73±1.68) min]. The difference was statistically significant( P<0.01). Conclusion:In superficial branch of the SCIA perforator flap transfer, if the upper or anterior wall of the main artery in the recipient area has a branch that matches the flap artery, the flap artery should first be anastomosed with its end. Because it dose not required to make a side port, and makes the operation more convenient with a short anastomosis time; Otherwise, perform end-to-side anastomosis with the main artery of the recipient site.

Volar Resurfacing of the Thumb with a Superficial Circumflex Iliac Artery Perforator Flap after Hydrofluoric Acid Burn.

A right-hand-dominant 55-year-old male automotive mechanic presented 24 hours following a hydrofluoric acid burn to the volar left thumb. Despite the severity of soft tissue injury, the neurovascular bundles were intact. Although a free toe-pulp flap is often described to cover volar digit defects, the resultant 6- × 4-cm full-thickness injury of the thumb was too large to be adequately covered by a toe-pulp flap or other commonly used local flaps from the ipsilateral hand. The authors used a superficial circumflex iliac artery perforator (SCIP) flap to reconstruct the volar surface of the thumb from the tip to the metacarpophalangeal joint. They used an arterial anastomosis with the princeps pollicis artery so that the anastomosis was well outside the zone of injury. The patient recovered from the procedure without event and was discharged home on postoperative day 5. At his 2-week postoperative visit, protective sensation with diminished light touch was intact. The authors conclude that the SCIP flap is a technically challenging but versatile, thin flap with minimal donor site morbidity that can be used to resurface the volar aspect of the thumb. The SCIP flap is a valuable resource for the hand surgeon confronted with larger soft tissue defects of the hand.

The reevaluation and surgical strategy of the superficial circumflex iliac artery perforator (SCIP) flap / 中华显微外科杂志

Objective To introduce the classification of the perforators of the superficial circumflex iliac artery(SCIA),and the superficial circumflex iliac artery perforator (SCIP) flaps based on different perforators have different characters and harvesting methods.To explore a set of coping strategy for the drawbacks of the SCIP flap.Methods Review 90 cases of SCIP flaps in August,2011 to June,2017.The pre-operative radiology navigation was conducted in all cases.Different surgical approaches were applied in flaps based on different perforators.The pedicle elongation method was adopted when necessary.The thickness of the flap,the length of the pedicle,the survival rate of the flap and the closure of the donor site were analyzed.Regular follow-up was performed after the operation.Results All flaps were followed-up for 6-15 months (average 8 months).Fifty-seven flaps were raised on the basis of the proximal perforators of the superficial branch of the SCIA,whereas 29 cases were based on the distal perforators from the deep branch,and in 4 cases,the pedicle was switched to the superficial inferior epigastric artery.In 8 cases,the arterial pedicle lengthen technique was applied with a maximum length of 10 cm.All donor sites were closed directly.Conclusion These surgical strategies simplified the intraoperative decision-making and conquered the shortcomings of the SCIP flap.It is believed that the SCIP flap can possibly become the new workhorse flap in the field of reconstructive surgery.

A reappraisal of the surgical planning of the superficial circumflex iliac artery perforator flap.

OBJECTIVE: The popularity of the superficial circumflex iliac artery perforator (SCIP) flap has been limited by factors such as variable vascular anatomy and short arterial pedicle. This article aimed to delineate flap design and harvest strategies based around either the proximal or distal perforators of the superficial circumflex iliac artery (SCIA) and propose a set of strategies that can help deal with the limitations of the flap. METHOD: From August 2011 to June 2015, the SCIP flap was used in 80 patients for soft tissue defects at our institution. We utilized vessel imaging navigation to get a detailed overview of the vascular anatomy preoperatively. Flaps were designed on the basis of either the proximal or distal perforators of the SCIA. Backup strategies and surgical maneuvers were suggested to solve the problems that emerged during surgery. RESULTS: In total, 51 flaps were raised on the basis of the proximal perforators of the superficial branch of the SCIA, whereas 25 cases were based on the distal perforators from the deep branch, and in four cases, the pedicle was switched to the superficial inferior epigastric artery. In eight cases, the arterial pedicle lengthen technique was applied with a maximum length of 10 cm. All donor sites were closed directly with inconspicuous scars. CONCLUSION: These surgical strategies simplified the intraoperative decision-making and overcame the shortcomings of the SCIP flap. We believe that the SCIP flap has a great potential to become a new workhorse flap in the field of reconstructive surgery.

A case of donor-site lymphoedema after lymph node-superficial circumflex iliac artery perforator flap transfer.

Vascularised lymph node transfer is a promising technique to treat limb lymphoedema, especially when caused by lymph node dissection. The most common approach is the transfer of superficial inguinal lymph nodes using groin flaps or superficial circumflex iliac artery perforator flaps. Lower-limb lymphatic sequelae are unexpected as these lymph nodes should drain lymph from the lower abdominal wall. Recently, Vignes et al. described two cases out of 26 cases of chronic lymphoedema after superficial inguinal lymph node harvest. From a series of 42 vascularised lymph node transfers performed at our centre, only one patient developed swelling in the donor thigh. The features of this patient who underwent a lymph node-containing superficial circumflex iliac artery perforator flap are reported herein. We recommend maximal accuracy in selecting the appropriate lymph nodes for transfer and provide some tips from our experience.
