Evaluation of the Efficacy and Safety of Pedicled Perforator Flap Technique for Salvage Nipple Reconstruction in Breast Cancer Patients: A Pilot Study.

We propose a pedicled perforator flap technique for salvage nipple reconstruction after initial nipple reconstruction fails in breast cancer patients. This is a pilot study. A total of 21 female breast cancer patients who underwent nipple reconstruction following initial nipple reconstruction fails were enrolled, and salvage nipple reconstruction based pedicled perforator flap were performed between 2016 and 2020. Operative time, perforator design, postoperative complications, follow-up duration, projection of nipple, as well as patient-reported outcomes measured by the BREAST-Q and visual analogue scale (VAS) were assessed. Sixteen patients underwent fifth lateral intercostal artery perforator reconstruction, while 5 patients underwent fifth anterior intercostal artery perforator flap reconstruction. The surgeries were successful without intraoperative complications, with a mean operative time of 67 minutes. Postoperative complications were absent. The mean follow-up duration was 18 months. The mean nipple projection was 8mm (range, 6-10mm) with a shrinkage of 20% at 6 months after surgery. The average scores for psychosocial well-being, satisfaction with breasts, and satisfaction with nipples domains of the BREAST-Q significantly increased (P < .01) at 6 months post-reconstruction. Sexual well-being subdomain showed no statistical difference (P = .9369). The VAS scores for cosmesis and patient satisfaction with surgery were 9 and 9.3, respectively. The pedicled perforator flap technique for salvage nipple reconstruction is a safe and effective approach.

Latissimus dorsi mini flap versus thoracodorsal artery perforator flap in reconstruction of partial mastectomy defects in early breast cancer: a prospective comparative study

Background Breast cancer is the most common cancer type among women and can lead to death. The surgical management of breast cancer has witnessed a considerable evolution in the past few decades. The aim was to compare the thoracodorsal artery perforator (TDAP) flap with the latissimus dorsi (LD) mini flap in the reconstruction of outer quadrants partial mastectomy defects in early breast cancer patients regarding feasibility, cosmesis, postoperative complications, and early musculoskeletal functional outcome. Patients and methods A prospective randomized study was carried out on 40 consecutive female patients complaining of early breast cancer (stages I, II), undergoing partial breast resection (lumpectomy or quadrantectomy with axillary lymph node dissection), and with a small tumor to breast volume ratio. All patients were randomized into two equal groups in a parallel manner by computer-generated numbers, and their allocation code was kept in a closed opaque envelope: group I: early breast cancer (stages I, II) who underwent mastectomy defect by either TDAP flap. Group II: early breast cancer (stage I, II) who underwent mastectomy the LD mini flap. Results Operation time, drain removal, and hospital stay were significantly lower in LD mini-flap group than TDAP flap group (P=0.032, P&lt;0.05, respectively). Complications and reoperation were insignificantly different between the two groups. Shoulder mobility 6 months and breast scar satisfaction was significantly higher in LD mini-flap group than TDAP flap group (P=0.045 and 0.009, respectively). Breast scar satisfaction and total score of satisfaction were significantly higher in LD mini-flap group than TDAP flap group (P&lt;0.05). Time of adjuvant therapy (first cycle) was insignificantly different between both groups. Conclusions In early breast cancer patients, the LD mini flap is a superior technique to TDAP as it had lower operation time, short hospital stays, drain removal, breast scar satisfaction, and total score of patient satisfaction but with high shoulder mobility affection.

The Facial Artery Perforator Flap for Reconstruction of Facial Defects: Surgical Pearls and Clinical Series.

Based on the knowledge of facial vascularity, facial artery perforator flaps could be used as potent tools for facial defect reconstruction. However, lack of experience and misconception of this technique limits the broad application in the clinical background. Here, we discussed surgical techniques based on our previous experience with facial artery perforator (FAP)-based facial defect reconstruction. A retrospective review of 12 patients undergoing facial defect reconstruction using an FAP flap was performed, including 8 defects in the mid-facial part and 4 defects in the nasal area generally resulted from basal cell carcinoma (8 patients), squamous cell carcinoma (3 patients), and actinic keratosis (one patient). All patients received one-stage FAP flap reconstruction. The overall follow-up period was 6 to 12 months. All reconstructions were successful with satisfactory patient-reported outcome and no local recurrence. No significant complications were observed in most cases, except for one instance of partial flap loss. Overall, taking advantage of FAP flaps will contribute to a good functional and esthetic outcome of facial defect reconstructions.

A cadaveric study and clinical application of the free superficial circumflex iliac artery perforator flap reconstruction of limb soft tissue defects

Introduction In recent decades the superficial circumflex iliac artery perforator (SCIP) flap technique has gradually overcome the previous disadvantages of its pedicle and donor site to be widely applied in treating tissue's defects. This article investigates the vascular anatomy of the SCIP flap and evaluates the result of using the flap to reconstruct limb defects. Materials and Methods The study was performed in two parts. Firstly a cross-sectional descriptive anatomical study comprising 49 groin dissections in 25 cadavers, with contrast radiographic demonstration of the vascular anatomy. Secondly a retrospective case series of 51 free SCIP flaps in 49 patients. Surgical outcomes were evaluated using the Vancouver Scar Scale on the regional function and the aesthetics of implanted flap and donor sites. Results The results of anatomical analysis on cadavers showed the superficial circumflex iliac arteries were detected in all specimens with an average diameter of 1.4 ± 0.3 mm. The superficial subcutaneous venous systems were also recorded, including two veins (superficial circumflex vein and superficial epigastric vein) in 79.5% with an average diameter of 2.3 ± 0.6 mm. The flap results showed the alive flap rate was 90.2%, partial-necrosis flap was 3.9% and total necrosis of the flap in 5.9%. In the aesthetic evaluation, fine line scars were seen in 13/51 cases (25.5%), stretch scars in 33/51 cases (64.7%) and hypertrophic scars in 5/51 patients (9.8%), with no cases of keloid scars. Conclusion The SCIP flap is a reliable free-tissue transfer for reconstructing limb soft tissue defects. Moreover, the SCIP flap is an ideal flap with pleasing aesthetics because the donor-site scar is situated in a well-hidden site. Care must be taken when vein grafts are used to lengthen the flap as flap necrosis rates increase.

The authors present a how-to-do-it guide for a dorsal metatarsal artery perforator (DMtAP) flap reconstruction of the foot following a burns injury.

Bilateral Free Deep Inferior Epigastric Artery Perforator Flaps for Reconstruction following Mastectomy in Poland Syndrome Patients.

Poland syndrome is classically described as symbrachydactyly, with hypoplasia of the pectoralis major and other upper thoracic musculoskeletal structures. It is thought to be caused by intrauterine interruption in subclavian arterial flow and often includes breast hypoplasia. Affected vasculature can pose a challenge for reconstruction with free flaps because inflow may not be reliable in this patient population. We present the rare case of a 28-year-old woman with left-sided Poland syndrome, significant family history of breast cancer, and BRCA1+ mutation who underwent bilateral prophylactic nipple-sparing mastectomies with successful immediate bilateral deep inferior epigastric artery perforator free flap reconstruction. The surgical literature in this clinical scenario is also reviewed. Preoperative computed tomography angiography of the chest successfully demonstrated the patency and quantified the caliber of the internal mammary vessels to support free flap breast reconstruction. Free tissue transfer is a viable option for breast reconstruction in patients with Poland syndrome undergoing mastectomy guided by preoperative computed tomography angiography to characterize the internal mammary vasculature.

Skin deformation analysis for pre-operative planning of DIEAP flap reconstruction surgery.

Deep inferior epigastric artery perforator (DIEAP) flap reconstruction surgeries can potentially benefit from augmented reality (AR) in the context of surgery planning and outcomes improvement. Although three-dimensional (3D) models help visualize and map the perforators, the anchorage of the models to the patient's body during surgery does not consider eventual skin deformation from the moment of computed tomography angiography (CTA) data acquisition until the position of the patient while in surgery. In this work, we compared the 3D deformation registration from supine arms down (CTA position) to supine with arms at 90° degrees (surgical position), estimating the patient's skin deformation. We processed the data sets of 20 volunteers with a 3D rigid registration tool and performed a descriptive statistical analysis and statistical inference. With 2.45mm of root mean square and 2.89mm of standard deviation, results include 30% cases of deformation above 3mm and 15% above 4mm. Pose transformation deformation indicates that 3D surface data from the CTA scan position differs from data acquired in loco at the surgical table. Such results indicate that research should be conducted to construct accurate 3D models using CTA data to display on the patient, while considering projection errors when using AR technology.

Latissimus Dorsi Flap and Thoracodorsal Artery Perforator Flap with Immediate Fat Transfer (LIFT and TIFT): A Retrospective Study about Total Breast Reconstruction in High-Risk Patients.

Microsurgical breast reconstruction has become popular over the past twenty years and allows a tailor-tuck approach to each patient. However, smoking or coagulation disorders may switch surgeon's choice towards alternative options. When facing these risk factors, we performed pedicled latissimus dorsi (LD) flap and thoracodorsal artery perforator (TDAP) flap reconstruction with immediate fat transfer (LIFT and TIFT), achieving satisfactory surgical outcomes. Hence, we aim to present our seven-years case-series and discuss our decisional algorithm. Thirty smoker women and seven women affected by coagulation disorder (n = 37) respectively had LIFT and TIFT surgery and were retrospectively evaluated. Patients' demographics and outcomes were recorded and compared. LIFT patients received higher volumes of immediate fat grafting compared to TIFT patients (p < 0.05), which required additional lipofilling to provide adequate volume amount, since the TDAP flap was not immediately grafted. However, the additional lipofilling procedures and fat volume were similar (p > 0.05). Flap survival reached 100%, and flap necrosis or loss did not occur. Few minor complications were evidenced in the LIFT group only (p > 0.05). Based on our experience, we support the reliability of pedicled LD and TDAP flaps with immediate fat transfer in breast reconstruction as valuable alternative to microsurgery in smokers (LIFT) and patients with coagulation disorders (TIFT). However, the results of our study are not conclusive since still must be clarified the role of the smoking and coagulation disorders in microsurgery and the real benefit of a non-microsurgical procedure.

Use of Super-thin Superficial Circumflex Iliac Artery Perforator Flap for Reconstruction of Lower Lip Defect.

Wide local excision remains the main treatment modality for primary lip cancer, which often results in considerable deficits of lip tissue and requires reconstruction using free tissue transfer. Although diverse free flaps, such as radial forearm flap or anterolateral thigh flap, have been used, their application is often limited by their inherent limitations including donor morbidity and flap bulkiness. This report details our experience of lower lip reconstruction using a super-thin superficial circumflex iliac artery perforator (SCIP) free flap.

Postoperative Day 1 Discharge in Deep Inferior Epigastric Artery Perforator Flap Breast Reconstruction.

An institutional review board-approved, retrospective chart review of patients undergoing DIEP flap breast reconstruction from January 2019 to March 2022 at Atrium Health was completed, consisting of 510 patients and 846 DIEP flaps. Patient demographics, medical history, operative course, and postoperative complications were collected. Twenty-three patients totaling 33 DIEP flaps were discharged on POD1. The POD1 group and the group of all other patients (POD2+) had no difference in age, ASA score, or comorbidities. BMI was significantly lower in the POD1 group (P = 0.039). Overall operative time was significantly lower in the POD1 group, and this remained true when differentiating into unilateral operations (P = 0.023) and bilateral operations (P = 0.01). No major complications occurred in those discharged on POD1. POD1 discharge after DIEP flap breast reconstruction is safe for select patients. Lower BMI and shorter operative times may be predictive in identifying patients as candidates for earlier discharge.

Propeller posterior tibial artery perforator flap for reconstruction of the medial malleolar defect: A case report

Abstract Traumatic injury to the distal third of the lower leg remains challenging and often requires free tissue transfer. Reconstructive options for lower leg soft-tissue defects require comprehensive evaluation. A 20-year-old man presented with a medial malleolar soft-tissue defect with exposure of the great saphenous vein, distal tibia, and ankle joint after a traffic accident. Negative pressure wound therapy provided only partial coverage of the exposed tissue. The defect was reconstructed using a local fasciocutaneous propeller flap based on a septocutaneous perforator from the posterior tibial artery. At 1-year follow-up, the patient resumed normal daily activities without functional deficits. We review the options of reconstructing the distal third of the lower leg and surgical pearls of propeller flaps. Propeller flaps provide adequate tissue-like and pliable soft tissue coverage with a short operation time. It can be a useful technique for the reconstruction of distal third lower-leg defects.

Analysis of Survival Quality of Peroneal Artery Perforator Flap in Immediate Repairment and Reconstruction of Oral and Maxillofacial Malignancies.

This study aimed to investigate the survival quality of peroneal artery perforator flap in the reconstruction of oral and maxillofacial malignant tumors. Thirty-two cases with a diagnosis of oral and maxillofacial malignant tumors admitted to our hospital from January 2019 to December 2019 were randomly divided into 2 groups. The observation group was reconstructed with free open artery perforator flaps, and the control group was repaired with free forearm flaps. The observation group had significantly lower scores in terms of postoperative pain, appearance, and anxiety, compared with the control group ( P <0.05). Both groups had high scores on taste, saliva, and shoulder function although there was no significant difference ( P >0.05). The scores of the observation group were significantly higher than those in the control group in terms of chewing, swallowing, speech, activity, mood, and entertainment ( P <0.05). There was 1 case accompanied by postoperative wound dehiscence and 2 cases with wound infection in the observation group while there were 3 cases with wound dehiscence and 2 cases with wound infection in the control group ( P >0.05). Compared with the forearm flap, the peroneal artery perforator flap can improve the survival quality of patients, especially in postoperative function with the fibula joint to repair the oral and maxillofacial defects. It has a wide application prospect as one of the ideal flaps in oral and maxillofacial postoperative repair and reconstruction.

Different forms of free radial collateral artery perforator flaps for reconstruction after removal of oral tumors

Objective: To investigate the efficacies of different forms of free radial collateral artery perforator flaps in repairing the defects after oral tumor surgeries. Methods: From May 2016 to March 2021, 28 patients (22 males, 6 females, aged 35-62 years) with oral tumors admitted by Hunan Cancer Hospital received the reconstructive surgeries with the free radial collateral artery perforator flaps after removal of oral tumors, including 24 cases of tongue cancer (11 cases of tongue marginal cancer, 9 cases of tongue belly cancer and 4 cases of tongue cancer involved in the floor of the mouth) and 4 cases of buccal and oral cancer. Four forms of radial collateral artery perforator flaps were used: single perforator flaps for 6 cases, double perforators flaps for 7 cases, flaps without perforator visualization for 10 cases and chimeric perforator myocutaneous flaps for 5 cases. The recipient vessels were the superior thyroid artery and superior thyroid vein, and if second concomitant vein available, it was anastomosed with internal jugular vein in end-to-side fashion. SPSS 20.0 statistical software was used to analyze the data. Results: The mean length of flaps was (9.7±0.4) cm, mean width (4.4±0.3) cm and mean thickness (1.1±0.4) cm. The mean length of the vascular pedicles was (7.1±0.6)cm (6.0-8.0 cm), the mean diameter of the radial accessory arteries was (1.1±0.3)mm (0.8-1.3 mm). Eleven cases(39.3%) had respectively one accompanying vein and 17 cases(60.7%) had respectively two accompanying veins, with the mean diameter of (1.1±0.3) mm (0.8-1.3 mm). All the 28 flaps survived, the donor and recipient wounds healed in one stage, the appearances of the flaps were satisfactory, only linear scars remained in the donor sites, and the upper arm functions were not significantly affected. Follow up for 12-43 months showed that the flaps were soft with partially mucosalization, the reconstructed tongue and buccal cavity were in good shape, and the swallowing and language functions were satisfactory. The swallowing and language functions were retained to the greatest extent in 3 cases with near total tongue resection, although the functions were still significantly affected. There was no local recurrence of the tumor during follow-up. One case had regional lymph node metastasis, and further lymph node dissection and comprehensive treatment were performed, with satisfactory outcomes. Conclusions: The vascular pedicle of the radial collateral artery perforator flap has a constant anatomy, which can be prepared in different forms to improve the safety of the operation and minimize the donor site damage. It is an ideal choice for the repair of small and medium-sized defects after oral tumor surgery.

Perforator mapping and clinical experience with the superthin profunda artery perforator flap for reconstruction in the upper and lower extremities

Thin skin flaps have gained popularity for extremity reconstruction. However, the use of the profunda artery perforator (PAP) flap has not been explored as much. With its concealed donor site on the medial thigh and bulk, the PAP has become popular for reconstruction in the breast, head, and neck. The thickness of the subfascial PAP flap is decreased through elevation on the thin or superthin plane, making it more suitable for extremity reconstruction. A consecutive series of 28 patients with 29 flaps who received a thin or superthin single perforator PAP flap for upper or lower extremity reconstruction was reviewed. Our technique for preoperative localization of the dominant perforator using computed tomography angiography (CTA) and color duplex ultrasonography (CDU) is described. Flap success rate was 93.1%. Mean flap artery diameter, vein diameter, area, and thickness were 1.7+0.4mm, 2.2+0.4mm, 157.3+52.1cm2, and 0.7+0.2cm, respectively. Skin thickness at the suprafascial bifurcation point of a dominant "T" perforator measured on preoperative CTA correlated with actual intraoperative flap thickness. Patient body mass index did not correlate with flap thickness. The thin and superthin PAP flap has multiple favorable characteristics, making it suitable for extremity reconstruction, and it has become the workhorse skin flap in our institution. Conventional low-frequency CDU together with CTA can be used effectively to map the dominant perforator preoperatively, allowing accurate flap design and rapid flap harvest. Therapeutic Level IV.

Pre-operative Radiotherapy And Deep Inferior Epigastric Artery Perforator (DIEP) flAp study (PRADA): Aesthetic outcome and patient satisfaction at one year

The optimal combination of radiotherapy and breast reconstruction has not yet been defined. Post-mastectomy radiotherapy (PMRT) has deleterious effects on breast reconstruction, leading to caution amongst surgeons. Pre-operative radiotherapy (PRT) is a growing area of interest, is demonstrated to be safe, and spares autologous flaps from radiotherapy. This study evaluates the aesthetic outcome of PRT and deep inferior epigastric artery perforator (DIEP) flap reconstruction within the Pre-operative Radiotherapy And Deep Inferior Epigastric artery Perforator (DIEP) flAp (PRADA) cohort. PRADA was an observational cohort study designed to evaluate the feasibility and safety of PRT for women undergoing neoadjuvant chemotherapy and DIEP reconstruction. Panel evaluation of 3D surface images (3D-SIs) and patient-reported outcome measures (BREAST-Q) for a subset of women in the study were compared with those of a DIEP-PMRT cohort who had undergone DIEP reconstruction and PMRT. Seventeen out of 33 women from the PRADA study participated in this planned substudy. Twenty-eight women formed the DIEP-PMRT cohort (median follow-up 23 months). The median (inter-quartile range [IQR]) 'satisfaction with breasts' score at 12 months for the PRADA cohort was significantly better than the DIEP-PMRT cohort (77 [72-87] versus 64 [54-71], respectively), p=0.01). Median [IQR] panel evaluation (5-point scale) was also significantly better for the PRADA cohort than for the DIEP-PMRT cohort (4.3 [3.9-4.6] versus 3.6 [2.8-4] p=0.003). Aesthetic outcome for the PRADA cohort was reported to be 'good' or 'excellent' in 93% of cases using a bespoke panel assessment with robust methodology. Patient satisfaction at one year is encouraging and superior to DIEP-PMRT at 23 months. Switching surgery-radiotherapy sequencing leads to similar breast aesthetic outcomes and warrants further large-scale, multi-centre evaluation in a randomised trial.

Evaluation of Gluteal Artery Perforator Flaps in Reconstruction of Gluteal Pressure (Decubitus) Ulcers

Evaluation of Gluteal Artery Perforator Flaps in Reconstruction of Gluteal Pressure (Decubitus) Ulcers

Pedicled Superficial Circumflex Iliac Artery Perforator (SCIP) flap for perineo-scrotal reconstruction following Fournier's gangrene.

Fournier's gangrene is a form of necrotising fasciitis involving perineo-scrotal skin. It is treated with radical debridement, infection control and often leaves a large anatomical defect that is challenging to reconstruct. The anatomical location of the defect leads to faecal contamination, difficulties when mobilizing, and negative psychological impact. Traditional approaches for managing such defects have relied on either healing by secondary intention or skin grafting. There are few reported cases in the literature to cover such defects with a flap. Pedicled Superficial Circumflex Iliac Artery Perforator (SCIP) flap reconstruction was performed in three patients who had perineo-scrotal defects following debridement for Fournier's gangrene. All flaps survived with no significant postoperative complications and good functional and aesthetic outcomes were achieved. The mean age of patient was 52 years and the largest defect measured 22 × 10 cm. The reconstruction of perineo-scrotal defects is difficult despite a range of reconstructive options. The pedicled SCIP flap offers many advantages over standard techniques. This flap is thin, pliable, and has a consistent anatomy. With continued experience, we feel that this flap could be considered the gold standard of treatment for such defects.
