Reconstructive surgeons frequently face challenges with free tissue transfer when transplanted flaps are thicker than intended. This is especially pronounced in lower limb cases, where the soft tissue below the knee is thin. The supra-fascial superficial circumflex iliac perforator (SCIP) flap overcomes this problem, but venous congestion remains a concern. We aim to examine the venous anatomy of the SCIP flap through cadaveric dissections and clinical data analyses to enhance the understanding of the venous anatomy and reduce venous congestion in future procedures. Eight cadaveric groins underwent venous dye injection and dissection to identify the superficial circumflex iliac vein (SCIV) and venae comitantes (VC) vascular networks. The venous anatomy was studied for dominant drainage. From April 2015 to December 2019, we conducted 102 SCIP flap reconstructions, mainly using the superficial circumflex iliac artery's superficial branch. Clinical data were analyzed and correlated with cadaveric dissections. SCIP flaps were categorized into three groups: dual drainage (VC and SCIV) in group I, SCIV-only in group II, and VC-only in group III. Correlations between clinical cases and cadaveric dissections revealed the SCIV as an independent drainage system with oscillating links to the VC. The SCIV is approximately twice the diameter of the VC, and the area of each vascular network suggests codominance. No significant difference in flap loss or venous congestion rates was noted when SCIV was the sole drainage, compared with VC or dual drainage. The SCIP flap with one artery and SCIV anastomosis, exhibits low venous congestion rates. Surgeons should consider SCIV for safe SCIP flap reconstruction. [ABSTRACT FROM AUTHOR]

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. 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. 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). 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. [ABSTRACT FROM AUTHOR]

Reconstruction after wide resection of a sarcoma arising in the shoulder girdle is challenging, and little evidence is available to compare short-term outcomes between pedicled-flap and free-flap reconstruction. Thirty-eight patients undergoing immediate reconstruction surgery with only a pedicled-flap (n = 18) and with a free-flap (n = 20) after sarcoma resection on the shoulder girdle between July 2005 and March 2022 were identified. One-to-one propensity score matching was performed to compare the postoperative complications. Transferred flaps survived completely in 20 cases in the free-flap group. In the all-patient analysis of binary outcomes, the occurrences of total complications, takebacks, total flap complications, and flap dehiscence were higher in the pedicled-flap group than in the free-flap group. The propensity score-matched analysis showed the occurrence of total complications was significantly higher in the pedicled-flap group than the free-flap group (53.8% vs. 7.7%, p = 0.03). In the propensity score-matched analysis of continuous outcomes, the pedicled-flap group demonstrated a shorter operation time than the free-flap group (279 vs. 381 min, p = 0.05). This clinical study demonstrated the feasibility and reliability of a free-flap transfer for the defect after wide resection of a sarcoma arising in the shoulder girdle. [ABSTRACT FROM AUTHOR]

We describe a variation of the superficial circumflex inguinal artery perforator (SCIP) flap, based the superficial branch of the superficial circumflex inguinal artery (SCIA) The vascular supply of the SCIP flap was prospectively studied in 91 preoperative CT angiograms in patients undergoing reconstruction with other flaps, and verified randomly with a hand-held doppler in 20% of them. Based on the results, a new SCIP flap was designed medial and cranial to the anterosuperior iliac spine (ASIS) using the superficial branch of the SCIA. This flap was used in 39 patients to reconstruct lower limb and head and neck defects The superficial branch of the SCIA was found in all patients and its exit point through Hesselbach's fascia was located within a 21 mm-radius circumference drawn 18 mm medial and 17 mm distal to the ASIS in 90% of the patients. Reconstruction with this SCIP flap was successful in 92.3% of the patients. Complications were present in 17.9% of the patients The design of the SCIP flap can be displaced cranially to obtain a larger flap with a long and constant vascular pedicle that is based on the main trunk of the SCIA. This facilitates the reconstruction of large and complex three-dimensional defects that require thin and pliable tissue, such as those located in the head and neck or limbs. Furthermore, supramicrosurgical expertise is not required. IV [ABSTRACT FROM AUTHOR]

Surgical therapy for vulvar cancer involves wide defects that often require flap-based reconstruction. The goal of the reconstruction is fast wound healing with low donor site morbidity. This is a retrospective observational cohort study in which we reviewed all patients who underwent surgery for vulvar cancer followed by reconstruction using the Superficial Circumflex Iliac Artery Perforator (SCIP) flap between 2015 and 2020. The primary outcome measure of this investigation was the incidence of wound complications. The secondary outcomes were the surgical indications in terms of establishing the anatomical subunits involved in the resection that made us choose this flap for reconstruction. This study adheres to the STROBE guidelines. Thirty-two patients were included; in two cases, the flap was performed bilaterally for a total of 34 SCIP flaps. The mean age of patients was 70.6 ± 8.6 years, and the mean BMI was 26.8 ± 4.7. The SCIP flap was always feasible. The mean flap size was 128.8 ± 74.3cm2. Three patients showed wound complications. In every patient, the defect involved the vulva, perineum and inguinal area; in 18 patients, the mons pubis was also involved. The mean follow-up was 30 months. During the follow-up, six patients died, and four showed local or nodal cancer relapse. Our results suggest that the advantages of SCIP flap for the reconstruction of vulvoperineal defects secondary to vulvar cancer surgery include low complication rate, minimal donor site morbidity, quick dissection, proximity of donor and recipient sites, possibility to harvest large skin islands of variable thickness and chimeric flaps.

The superficial circumflex iliac artery perforator (SCIP) flap has been established in Asia to provide an excellent option for soft tissue defect coverage. The main advantage of this delicate flap is its very thin design. However, the adoption of this technique in other parts of the world has been rarely reported. In this retrospective study, we analyzed outcomes of 32 SCIP flaps in a Caucasian patient population. The procedures were performed at our institution between March 2019 and August 2020. We present patient characteristics, surgical technique, perioperative care, and flap applications as compared to the Asian approaches. Patients' average BMI was 28.7. Flap anatomy and flap thickness at the superficial fascial plane differed significantly within our population. With 1.7 mm on average, the arterial diameter was higher than reported in the literature. Flaps were based on an axial perforator in 52% of cases. The SCIP flap was performed safely in the majority of cases. The surgical flap elevation approach was modified toward speedy perforator identification. The SCIP flap offers superior opportunities for thin soft tissue defect coverage with excellent functional outcomes in Caucasian patients. Based on higher BMI and anatomical differences as compared to Asian patient populations, modifications of flap elevation were necessary to increase reliability. More outcome reports from outside Asia need to become available to advance SCIP flap application internationally. [ABSTRACT FROM AUTHOR]

Contralateral 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. Between 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. Of 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. Unilateral DIEP flap breast reconstruction and contralateral SIEA flap breast augmentation may be safely performed with satisfactory results. [ABSTRACT FROM AUTHOR]

Abdominopelvic defect is frequently a challenge. Several local flaps exist for this anatomical region, but sequelae of the donor site, particularly with regard to morbidity on the anterior abdominal wall, are frequent. Although the utility of the superficial circumflex iliac artery flap is well established in its free form as well as its pedicled form described by McGregor, the superficial circumflex iliac artery perforator (SCIP) propeller flap is rarely reported. The purpose of this study is to highlight the possible range of locoregional coverage using the SCIP propeller flap. Between 2012 and 2018, 72 SCIP flaps were made in the propeller version to cover locoregional defects of various etiologies in our units. The dimensions of SCIP flaps were on average 20.2 cm long (9–39) by 8.2 cm wide (5–18). The average rotation angle was 163.3° (range 130–180). In sixteen patients, SCIP flaps were bilateral. In five cases, the reconstruction was combined with a contralateral Tensor Fascia Lata (TFL) flap to cover a very large defect. Two SCIP flaps necrotized following global venous congestion and a TFL flap was performed in rescue. No complications appeared on the donor site and the patients did not have any functional complications related to the reconstruction. Particular care was taken to respect the lateral cutaneous nerve of the thigh. The SCIP propeller flap provides a reliable and versatile method for reconstructing abdominoperineal defect, including the thigh root region to the trochanters with low donor site morbidity.

Summary Introduction Perioperative microsurgical planning increases the likelihood of successful results. Augmented reality (AR) is the addition of artificial information to allow the user to perform tasks more efficiently. The aim of our study is to report the use of AR for microsurgical planning with a smartphone (ARM-PS) as a dissection route map. Patients and methods AR was used for superficial circumflex iliac artery perforator (SCIP) flap planning. Three-dimensional (3D) reconstruction images of the inguinal and lower abdomen vascular anatomy were obtained by computed tomography angiography. These 3D images were imported to a smartphone and an AR app was used to superimpose them with the camera. The drawings performed with ARM-PS were correlated with handheld Doppler and intraoperative findings. Results The correlation of ARM-PS drawings with handheld Doppler results was 100% for superficial inferior epigastric artery (SIEA) and superficial and deep branches of SCIP in 60 inguinal areas studied. Intraoperative findings matched perfectly in all 30 cases with ARM-PS drawings for the location of the mentioned vessels and lymph nodes. Flap harvest time decreased in 20% compared with our traditional timing. Conclusions ARM-PS is an easy, noninvasive, and accurate method that provides a dissection route map, thereby standardizing flap harvesting, and shows a perfect correlation with intraoperative findings. It reduces operating time and may improve operative results, thus decreasing donor site morbidity. [ABSTRACT FROM AUTHOR]

Summary In head and neck reconstruction using free flaps, microvascular anastomosis is commonly performed in an end-to-end fashion to relatively sizable arteries including the superficial temporal, facial, and superior thyroid arteries. With the recent developments of less invasive perforator flaps such as the superficial circumflex iliac artery perforator flap, anastomosis of smaller vessels of less than 0.8 mm diameter has become necessary; however, appropriate recipient arteries for end-to-end anastomosis are often absent. We have introduced supermicrosurgical end-to-side anastomosis to such arteries in 12 cases of head and neck reconstruction. Double-needle, short-thread microsutures were used to facilitate this procedure, and indocyanine green intraoperative angiography was used to confirm patency. All patients, except one with partial necrosis, survived. We believe that our method is a safe and reliable option for cases in which there is a discrepancy between the flap pedicle and recipient arteries. [ABSTRACT FROM AUTHOR]

Summary Introduction Superficial circumflex iliac artery perforator (SCIP) flap is based on the perforator of superficial circumflex iliac artery (SCIA) system, and is a highly useful surgical tool with a wide variety of clinical applications. The SCIA system is associated with considerable anatomical variation, however, rendering transfer of a SCIP flap technically difficult. Patients and methods Using preoperative color Doppler ultrasound (US), we examined a total of 11 flaps of 11 patients who had undergone reconstruction with SCIP flap from April to August of 2014. The origin of SCIA from femoral artery and the bifurcation of its superficial branch and deep branch were easily identifiable in all patients. Perforator courses and their penetration points were marked to guide dissection. Results Although one patient required secondary revision and skin grafting because of partial necrosis, there were no serious postoperative complications such as total necrosis or resulting absorption of the transferred adiposal flap. In all cases, findings from the preoperative color Doppler US were useful in delineating the dominant vessel within the groin lesion. Conclusion Using the technique described above, difficulties arising from the anatomical variation within the SCIA system are easily overcome, simplifying SCIP flap harvest. In addition to being relatively easy, the technique is also quick to administer and safe. [ABSTRACT FROM AUTHOR]
