Breast reconstruction using perforator flaps   总被引:4,自引:0,他引:4  
BACKGROUND: Perforator flaps allow the transfer of the patient's own skin and fat in a reliable manner with minimal donor-site morbidity. The deep inferior epigastric artery (DIEP) and superficial inferior epigastric artery (SIEA) flaps transfer the same tissue from the abdomen to the chest for breast reconstruction as the TRAM flap without sacrificing the rectus muscle or fascia. Gluteal artery perforator (GAP) flaps allow transfer of tissue from the buttock, also with minimal donor-site morbidity. INDICATIONS: Most women requiring tissue transfer to the chest for breast reconstruction or other reasons are candidates for perforator flaps. Absolute contraindications to perforator flap breast reconstruction include history of previous liposuction of the donor site or active smoking (within 1 month prior to surgery). ANATOMY AND TECHNIQUE: The DIEP flap is supplied by intramuscular perforators from the deep inferior epigastric artery and vein. The SIEA flap is based on the SIEA and vein, which arise from the common femoral artery and saphenous bulb. GAP flaps are based on perforators from either the superior or inferior gluteal artery. During flap harvest, these perforators are meticulously dissected free from the surrounding muscle which is spread in the direction of the muscle fibers and preserved intact. The pedicle is anastomosed to recipient vessels in the chest and the donor site is closed without the use of mesh or other materials. CONCLUSIONS: Perforator flaps allow the safe and reliable transfer of abdominal tissue for breast reconstruction.  相似文献

与游离穿支皮瓣相比,带蒂穿支皮瓣分离技术更加简单,安全系数更高,而且供区畸形更小。近年来,应用带蒂穿支皮瓣技术已经成为乳房再造手术一种新的选择, 甚至是一些患者的首选方案。常用的带蒂穿支皮瓣有胸背动脉穿支皮瓣、肋间动脉穿支皮瓣(外侧肋间动脉穿支皮瓣、前侧肋间动脉穿支皮瓣)等,其他可用的选择包括前锯肌动脉穿支皮瓣,腹壁上动脉穿支皮瓣,胸外侧动脉穿支皮瓣等。为了提高手术设计的精确性,术前需要评估穿支血管的质量,并对其定位穿支。皮瓣的设计相比游离皮瓣手术而言,显得更加重要。虽然带蒂穿支皮瓣在乳房再造领域的作用尚不能取代游离皮瓣的金标准地位,但随着“损伤最小化”重建概念的日渐推广,带蒂穿支皮瓣将会成为乳房再造领域里的一种新的趋势。  相似文献

The advantage of free perforator flaps versus free musculocutaneous flaps is the reduced morbidity of the donor site with preservation of nerves, muscles and deep fascia. In this study, we evaluated the reconstruction results of deep inferior epigastric artery perforator (DIEAP) free flaps in the head and neck. A retrospective review was performed of 12 patients with head and neck tumor ablation defects that were reconstructed with the deep inferior epigastric artery perforator (DIEAP) free flaps between January 2004 and December 2006. Reconstruction outcomes and complications were measured. Recipient sites were subdivided into defects of total or subtotal glossectomy (N=6), three-dimensional defects of midface (N=3), through and through defects of the cheek (N=2), and anterior skull base resection with an external skin component defect (N=1).The overall free flap success rate was 92% (11/12). One DIEAP free flap was lost because the draining jugular vein thrombosed. No complications were observed in the donor site, including abdominal bulge or hernia. Due to the advantage of minimum donor site morbidity, the DIEAP free flap is a new and reliable reconstruction choice for head and neck surgical defects.  相似文献

Breast cancer is a ubiquitous disease and one of the leading causes of death in women in western societies. With overall increasing survival rates, the number of patients who need post-mastectomy reconstruction is on the rise. Especially since its psychological benefits have been broadly recognized, breast reconstruction has become a key component of breast cancer treatment. Evolving from the early beginnings of breast reconstruction with synthetic implants in the 1960s, microsurgical tissue transfer is on the way to become the gold standard for post oncology restoration of the breast. Particularly since the advent of perforator based free flap surgery, free tissue transfer has become as safe option for breast reconstruction with low morbidity. The lower abdominal skin and subcutaneous fat tissue typically offer enough volume to create an aesthetically satisfying breast mound. Nowadays, the most commonly used flap from this donor site is the deep inferior epigastric artery perforator flap. If the lower abdomen is not available as a donor site, the gluteal area and thigh provide a number of flaps suitable for breast reconstruction. If the required breast volume is small, and there is enough tissue available on the upper medial thigh, then a transverse upper gracilis flap may be a practicable method to reconstruct the breast. In case of a higher amount of required volume, a gluteal artery perforator flap is the best choice. However, what is crucial in addition to selecting the best flap option for the individual patient is the timing of the operation. In patients with confirmed post-mastectomy radiation therapy, it is advisable to perform microvascular breast reconstruction only in a delayed fashion.  相似文献

The optimal method for breast reconstruction should be safe, reliable, and accessible for every patient, and it should display little or no donor-site morbidity. After comparing mammary implants it has been found that autogenous breast reconstruction can create a ptotic, soft, symmetrical breast mound. The transverse rectus abdominis musculocutaneous flap (TRAM) remains the most popular method for autogenous reconstruction. Modern trends in breast reconstruction using the TRAM flap have promoted adequate blood supply to the flap while minimizing donor-site defects in the anterior abdominal wall. The pedicled TRAM flap remains one of the most frequently used flaps, but the indirect blood supply in this flap has required many modifications and refinements. Such modifications have included the bipedicled TRAM flap, the free TRAM flap, and the supercharged TRAM flap. To avoid donor-site morbidities, the muscle-sparing free TRAM, deep inferior epigastric perforator flap (DIEP), and superficial inferior epigastric artery (SIEA) flap were introduced. The DIEP perforator flap requires meticulous technique but offers proven reliability and a low rate of complications. As surgeons become more comfortable with harvesting DIEP flaps, the frequency of usage seems likely to increase. The latissimus dorsi musculocutaneous flap, gluteus maximus musculocutaneous flap, and others may be selected when these modifications of free TRAM flap are unavailable or unusable.  相似文献

Microvascular reconstruction of the breast   总被引:1,自引:0,他引:1  
The growth of microsurgical procedures has led to significant technological, scientific, and clinical advances that have made these procedures safe, reliable, reproducible, and routine in most major medical centers. In many instances, free flap reconstruction has become the primary reconstructive method for many major defects, including breast reconstruction. The advantages of free flap breast reconstruction include better flap vascularity, broader patient selection, easier insetting of the flap, and decreased donor site morbidity. Free flap breast reconstruction can occur either at the time that the mastectomy is performed or as a delayed reconstruction following a previous mastectomy. Immediate reconstructions have the advantage of avoiding scar contracture and fibrosis within the mastectomy flaps and at the recipient vessel site. The most common recipient vessel sites are the thoracodorsal vessels and the internal mammary vessels. The thoracodorsal vessels are most frequently used in immediate reconstruction because they are partially exposed during the mastectomy procedure. The internal mammary vessels are used more frequently in delayed reconstructions, to avoid repeat surgery in the axilla. This recipient site also allows more medial placement of the reconstruction. Flap selections for free autogenous breast reconstruction include the transverse rectus abdominis myocutaneous (TRAM) flap, the superior gluteal myocutaneous flap, the inferior gluteal myocutaneous flap, the lateral thigh flap, and the deep circumflex iliac soft tissue flap (Rubens). The TRAM flap is most commonly used in free flap breast reconstruction. For patients with inadequate abdominal tissue or prior abdominal surgery, the superior gluteal flap is typically used. Both the TRAM flap and the superior gluteal flap can be designed as perforator flaps, preserving all of the involved muscle and, in the TRAM perforator, all the rectus fascia. These flaps are more technically demanding, with minimal impact on donor site function. The other flaps are less frequently used and limited to special patient circumstances. Free flap autogenous breast reconstruction provides a natural, long-lasting result with a high degree of patient satisfaction. Semin. Surg. Oncol. 19:264-271, 2000.  相似文献

The transverse myocutaneous gracilis (TMG) and the profunda artery perforator (PAP) flap are both safe choices for autologous breast reconstruction originating from the same donor region in the upper thigh. We aimed to compare the post-operative outcome regarding donor-site morbidity and quality of life. We included 18 patients who had undergone autologous breast reconstruction with a PAP flap (n = 27 flaps). Prospective evaluation of donor-site morbidity was performed by applying the same questionnaire that had already been established in a previous study evaluating TMG flap (n = 25 flaps) outcome, and results were compared. Comparison of the two patient groups showed equivalent results concerning patient-reported visibility of the donor-site scar and thigh symmetry. Still, the TMG group was significantly more satisfied with the scar (p = 0.015) and its position (p = 0.001). No difference was found regarding the ability to sit for prolonged periods. Donor-site wound complications were seen more frequently in the PAP group (29.6%) than in the TMG group (4.0%). Both groups expressed rather high satisfaction with their quality of life. Both flaps show minimal functional donor-site morbidity and high patient satisfaction. To minimize wound healing problems in PAP patients, thorough planning of the skin paddle is necessary.  相似文献

ObjectiveTo create a comprehensive algorithmic approach to reconstruction after vulvar cancer ablative surgery, which includes both traditional and perforator flaps, evaluating anatomical subunits and shape of the defect.MethodsWe retrospectively reviewed 80 cases of reconstruction after vulvar cancer ablative surgery, performed between June 2006 and January 2016, transferring 101 flaps. We registered the possibility to achieve the complete wound closure, even in presence of very complex defects, and the postoperative complications. On the basis of these experience, analyzing the choices made and considering the complications, we developed an algorithm to help with the selection of the flap in vulvoperineal reconstruction after oncologic ablative surgery for vulvar cancer.ResultsWe employed eight types of different flaps, including 54 traditional fasciocutaneous V-Y flaps, 23 rectus abdominis myocutaneous flaps, 11 anterolateral thigh flaps, three V-Y gracilis myocutaneous flaps, three free style perforators V-Y flaps from the inner thigh, two Limberg flaps, two lotus flaps, two deep inferior epigastric artery perforator flap, and one superficial circumflex iliac artery perforator flap. The structures most frequently involved in resection were vulva, perineum, mons pubis, groins, vagina, urethra and, more rarely, rectum, bladder, and lower abdominal wall.ConclusionThe algorithm we implemented can be a useful tool to help flap selection. The key points in the decision-making process are: anatomical subunits to be covered, overall shape and symmetry of the defect and some patient features such as skin laxity or previous radiotherapy. Perforator flaps, when feasible, must be considered standard in vulvoperineal reconstruction, although in some cases traditional flaps remain the best choice.  相似文献

IntroductionAutologous breast reconstruction has evolved from more morbid procedures that sacrificed the abdominal muscle (the TRAM or transverse rectus abdominus muscle flap) to “perforator” flaps. Commercial insurers recognized the higher technical demand of perforator flaps by creating procedural codes with higher professional fees. This study examined whether procedure code discrepancies between insurance payers disproportionally incentivize perforator flaps among the commercially insured.MethodsAutologous breast reconstructions identified from the National Inpatient Sample (NIS) were subdivided into microvascular perforator (85.74, 85.75, 85.76), microvascular TRAM (85.73), and pedicled TRAM flaps (85.72). Demographics, comorbidities and access to care were compared. A logistic regression comparing microvascular reconstructions only was used to identify predictors for perforator flap reconstruction.ResultsA total of 66,968 cases of autologous breast reconstruction were identified. Perforator flaps were more likely among the commercially insured (p < 0.001) and higher insurance quartiles (p < 0.001).When comparing microvascular reconstruction, perforator flaps were 1.72 (p < 0.001) times more likely among the commercially insured. As compared to the lowest income quartile, the fourth quartile had an odds ratio of 1.36 (p < 0.001) for perforator flap reconstruction.ConclusionThe presence of a separate perforator flap billing code among the commercially insured may be exacerbating existing socioeconomic disparities in breast cancer reconstruction.  相似文献

Objective To identify possible avenues of sparing the internal mammary artery (IMA) for coronary artery bypass grafting (CABG) in women undergoing autologous breast reconstruction with deep inferior epigastric artery perforator (DIEP) flaps. Background Optimal autologous reconstruction of the breast and coronary artery bypass grafting (CABG) are often mutually exclusive as they both require utilisation of the IMA as the preferred arterial conduit. Given the prevalence of both breast cancer and coronary artery disease, this is an important issue for women??s health as women with DIEP flap reconstructions and women at increased risk of developing coronary artery disease are potentially restricted from receiving this reconstructive option should the other condition arise. Methods The largest clinical and cadaveric anatomical study (n = 315) to date was performed, investigating four solutions to this predicament by correlating the precise requirements of breast reconstruction and CABG against the anatomical features of the in situ IMAs. This information was supplemented by a thorough literature review. Results Minimum lengths of the left and right IMA needed for grafting to the left-anterior descending artery are 160.08 and 177.80?mm, respectively. Based on anatomical findings, the suitable options for anastomosis to each intercostals space are offered. In addition, 87?C91% of patients have IMA perforator vessels to which DIEP flaps can be anastomosed in the first- and second-intercostal spaces. Conclusion We outline five methods of preserving the IMA for future CABG: (1) lowering the level of DIEP flaps to the fourth- and fifth-intercostals spaces, (2) using the DIEP pedicle as an intermediary for CABG, (3) using IMA perforators to spare the IMA proper, (4) using and end-to-side anastomosis between the DIEP pedicle and IMA and (5) anastomosis of DIEP flaps using retrograde flow from the distal IMA. With careful patient selection, we hypothesize using the IMA for autologous breast reconstruction need not be an absolute contraindication for future CABG.  相似文献

Oncoplastic breast surgery has become a popular choice of treatment for breast reconstruction after mastectomy. There are two different techniques in oncoplastic surgery depending on the volume of the excised breast tissue. One is the volume displacement procedure, which combines resection with a variety of different breast-reshaping and breast-reduction techniques; the other is the volume replacement procedure in which the volume of excised breast tissue is replaced with autologous tissue. In this study, current authors performed various volume replacement techniques based on the weight of the excised tumor and its margin of resection. We used a latissimus dorsi myocutaneous flap for cases in which the resection mass was greater than 150 g, and for cases in which the resection mass was less than 150 g, we used a regional flap, such as a lateral thoracodorsal flap, a thoracoepigastric flap, or perforator flaps, such as an intercostal artery perforator flap or a thoracodorsal artery perforator flap. In the patients with small to moderate-sized breasts, when a postoperative deformity is expected due to a large-volume tumor resection, the replacement of non-breast tissue is required. Many of whom have small breasts, oncoplastic volume replacement techniques in breast-conserving surgery allow an extensive tumor excision without concern of compromising the cosmetic outcome and can be reliable and useful techniques with satisfactory aesthetic results.  相似文献

Mandible reconstruction with microvascular surgery   总被引:3,自引:0,他引:3  
Microvascular surgery has become the preferred method for mandible reconstruction. Whenever possible, immediate reconstruction at the time of segmental mandible resection will provide the best aesthetic and functional result. Four donor sites (fibula, iliac crest, radial forearm, and scapula) have become the primary sources of vascularized bone and soft tissue for the reconstruction. The fibula has multiple advantages, including bone length and thickness, donor site location permitting flap harvest simultaneously with tumor resection, and minimal donor site morbidity. The fibula donor site should be the first choice for most defects, particularly those with anterior or large bony defects requiring multiple osteotomies. Use of an alternative donor site is best reserved for cases with large soft tissue and minimal bone requirements. Dental rehabilitation through the use of prostheses and osseointegrated dental implants is an important part of the reconstructive process to optimize aesthetics and function. An algorithm for mandible reconstruction with microvascular osseous flaps is presented. Semin. Surg. Oncol. 19:226-234, 2000.  相似文献

BackgroundWhether the breast reconstruction modality could influence the long-term development of post-mastectomy lymphedema has been little investigated. The present study aimed to evaluate the potential association of the breast reconstruction method with the incidence of lymphedema over an extended follow-up period.MethodsPatients with breast cancer who underwent immediate reconstruction from 2008 to 2014 were reviewed. They were categorized into three groups according to the reconstruction method: tissue expander/implant, abdominal flaps, and latissimus dorsi (LD) muscle flaps. Differences in the cumulative incidence of lymphedema by the reconstruction method were analyzed, as well as their independent influence on the outcome. Further analyses were conducted with propensity-score matching for baseline characteristics.ResultsIn total, 664 cases were analyzed with a median follow-up of 83 months (402 prostheses, 180 abdominal flaps, and 82 LD flaps). The rate of axillary lymph node dissection was significantly higher in the LD flap group than in the other two groups. The 5-year cumulative incidences of lymphedema in the LD flap, abdominal flap, and prosthesis groups were 3.7%, 10.6%, and 10.9%, respectively. In multivariable analyses, compared to the use of the LD flap, that of tissue expander/implant and that of abdominal flaps were associated with increased risks of lymphedema. A similar association was observed in the propensity-score matching analysis. The use of abdominal flaps or prostheses was not associated with the outcomes.ConclusionsOur results suggest that the method of immediate breast reconstruction might be associated with the development of postmastectomy lymphedema.  相似文献

Background

A free fascioadipocutaneous flap obtained from the medial thigh is suitable for breast reconstruction in Asian women with a small-to-moderate breast size. In this region, both a medial circumflex femoral artery perforator flap (MCFAp flap) and a posterior medial thigh perforator flap (PMTp flap) are options, based on perforators from the deep femoral vessels. Here, we evaluated the anatomic basis of the medial circumflex femoral artery (MCFA) perforators from the medial circumflex femoral vessels.

Methods

Between July 2010 and June 2014, 53 patients (55 flaps) underwent breast reconstruction using a fascioadipocutaneous flap from the medial thigh. MCFA perforators larger than or equal to 0.5 mm in this region were investigated. The following parameters were recorded intraoperatively: number of perforators, perforator locations, distance of the perforating point from the proximal thigh crease and anterior border of the gracilis muscle.

Results

The total number of perforators was 131, with a mean of 2.4. The number of perforators coursing through the gracilis muscle (gracilis perforators) was the largest, followed by septocutaneous perforator coursing between the adductor longus and gracilis muscle. The average perforating point was located 6.5 cm below the proximal thigh crease and 2.2 cm from the anterior border of the gracilis muscle. Of the 102 procedures performed since 2006, 15 flaps were elevated as MCFAp flaps and there was no major complication.

Conclusions

In some cases, MCFA perforators are dominant in this region compared to PMT perforators. A perforator map can be helpful for identifying adequate MCFA perforators intraoperatively.

Although the number of patients with breast cancer continues to rise worldwide, survival rates for these patients have significantly improved. As a result, breast cancer survivors are living longer, and quality of life after treatment is of increasing importance. Breast reconstruction is an important component that affects quality of life after breast cancer surgery. With the development of silicone gel implants in the 1960s, autologous tissue transfer in the 1970s, and tissue expanders in the 1980s, breast reconstruction has advanced over the decades. Furthermore, the advent of perforator flaps and introduction of fat grafting have rendered breast reconstruction a less invasive and more versatile procedure. This review provides an overview of recent advances in breast reconstruction techniques.

The authors present five cases of combined oral mucosa-mandible defects reconstructed with thevascularized internal oblique-iliac crest myoosseous free flap. This technique has many advantages comparedto other conventional methods such as the radial flap, scapula flap, and fibula flap. Vascularized iliac crestflaps provide sufficient high-quality bone suitable for reconstructing segmental madibular defects. Althoughfibular flaps allow longer donor bone tissue to be harvested, the iliac crest can provide an esthetic shape formandibular body reconstruction and also provides sufficient bone height for dental implants. Conventionalvascularized iliac crest myoosseous flaps have excessive soft tissue bulk for reconstruction of intraoral softtissue defects. The modification discussed in the present article can reduce soft tissue volume, resulting inbetter functional reconstruction of the oral mucosa. Another advantage is that complete replacement of theoral mucosa is observed in as early as one month post-operation. The final mucosal texture is much betterthan that obtained with other skin paddle flaps, which is especially beneficial for the placement of dentalimplant prostheses. Donor site morbidity looks to be similar to, if not less than that observed for othermodalities in terms of function and esthetics. For combined oral mucosa-mandible defects, the vascularizedinternal oblique-iliac crest myoosseous free flap shows good results with respect to hard and soft tissuereconstruction.  相似文献
