Managed care's attempts to capture aesthetic surgery.

Managed care organizations recently have attempted to add aesthetic surgery to their line of available services. To better understand the challenges posed by these actions, all members of the American Society for Aesthetic Plastic Surgery were surveyed about managed care overtures to aesthetic plastic surgeons, their responses, and the likely responses of their patients. The goal was to examine both the supplier and consumer ends of the aesthetic surgery market to determine the likely effects of managed care's attempts to capture aesthetic surgery. A total of 632 plastic surgeons returned the surveys (response rate, 54.5 percent). Twenty-two percent reported being approached by managed care organizations about joining a panel of aesthetic surgeons. Approximately one-quarter of the plastic surgeons said they would participate in aesthetic surgery panels developed by managed care organizations. Characteristics significantly associated with willingness to participate were solo practice structure, a low percentage of practice revenues from aesthetic surgery, and a very competitive practice environment. Plastic surgeons believed that their colleagues would be even more willing to acquiesce to managed care aesthetic surgery; more than one-third said that 25 to 50 percent of their colleagues would join, and nearly one-third thought that more than half would participate. Plastic surgeons believed that many of their patients would also participate in managed care aesthetic surgery. Twenty-four percent thought that more than half of their patients would choose an aesthetic surgeon through their managed care organization if that organization developed a network for aesthetic surgery. This figure increased to almost 40 percent if the organization would deny coverage for complications resulting from nonpanel surgeons, and to 41 percent if the organization would offer price discounts. This survey shows that most plastic surgeons are against managed care aesthetic surgery. But it also shows that some plastic surgeons will participate, and that most plastic surgeons think many of their colleagues and patients will do likewise. This means that managed care organizations have the potential to make inroads in aesthetic surgery on both the supplier and consumer ends of the market. To prevent managed care from capturing aesthetic surgery, plastic surgeons must anticipate the likely business strategy of managed care. To this end, they must understand the steps involved in the creation of a new service business and offer organized countermeasures against each of them.

Alginate microbead release assay of angiogenesis.

Recently, the acceleration (and retardation) of blood vessel growth has been an increasingly frequent subject of study. With its potential application to a wide range of clinical disease processes, investigation certainly remains essential and promising. While in vitro investigation is traditional, well-controlled, and objective, studying angiogenesis in vivo can be quite difficult for a number of reasons. One major reason is the inherent tissue differences associated with blood vessel growth. Because all tissues are different, certain tissues tend to be inherently more vascular than others. As such, the growth (and concentration) of blood vessels occurs at different rates and proportions depending on that specific tissue. In the past several years, most in vivo angiogenesis work has been performed in the sclera as it allows for relatively easy access and the possibility of repeated observation. The sites to which investigation of angiogenesis might be applied, however, are invariably quite different and therefore additional tissues such as solid organs, fascia, muscle, and skin need to be studied as well. How can this be performed?

Wall Street's growing influence on plastic surgery.

The advent of managed care has unleashed market forces on the health care system. One result of these new pressures is a shift from nonprofit to Wall Street-based financing. This report quantifies these trends by comparing health organizations' financial structures in the 1980s and now. The reasons behind this shift and the function of the stock market are examined. A review of Wall Street's key financial measures confirms that health care has shifted to the stock market as its principal means of financing. The stock market works by assigning a current price to a company's stock based on estimates for future earnings. Thus, companies desire predictability in their costs, revenues, and profits. Plastic surgeons can master this system by meeting the challenges imposed by Wall Street financing. Important steps include continuously measuring costs and outcomes of procedures, demanding cost data from hospitals and payers, using these data to improve costs and outcomes, and taking advantage of the system's openness to innovation and easier access to capital. As they seek to protect their role as medical decision makers under the new free-market system, plastic surgeons can benefit from understanding the mechanisms of the stock market.

Combined revascularization and microvascular free tissue transfer for limb salvage: a six-year experience.

Atherosclerotic vascular disease causing extensive tissue loss of the lower extremities often results in primary amputation. Combined revascularization and free tissue transfer has been described as a method of extending limb salvage to these patients. The durability of this combined procedure remains unknown, thus the objective of this report is to describe the immediate and long-term results in a series collected over 6 years. From 1992 to 1998, 15 patients with a mean age of 60 years underwent combined revascularization and free tissue transfer. Mean ulcer size measured 45 cm(2) for a mean duration of 7.4 months preoperatively and 12 patients had exposed bone or tendon. Vascular reconstruction included popliteal (3), tibial (6), and pedal (6) bypass with concomitant myocutaneous free flap, using mostly rectus abdominis or latissimus dorsi muscle. There were no perioperative deaths. One patient suffered a nonfatal myocardial infarction. Two patients had a postoperative wound hematoma and one required vascular graft revision. Patients were followed for 4 to 75 months (mean = 23 months). Four patients have required amputations (3 early, 1 late), three of whom had preoperative renal failure. The limb salvage rate has been 72% at 36 months,

Aesthetic surgery economics: lessons from corporate boardrooms to plastic surgery practices.

Healthcare traditionally has been described as not conforming to the laws of economics. Consumers pay for aesthetic surgery directly, thus freeing it from the usual confounding factors and making it more likely to comply with the market forces explained by economics. Recent studies have demonstrated the ability of classic economics to analyze, predict, and optimize the financial environment of aesthetic surgery. This article describes economic principles and how they can be applied to aesthetic surgery. Some of the basic instruments of economics include the study of supply and demand, prices, and price elasticity; capital investments; communication and cooperation; and consumer cognitive limitations. Each of these tools offers plastic surgeons the opportunity to gain improved control of their financial environment.

Wall Street's assessment of plastic surgery--related technology: a clinical and financial analysis.

Many plastic surgeons develop technologies that are manufactured by Wall Street-financed companies. Others participate in the stock market as investors. This study examines the bioengineered skin industry to determine whether it integrates clinical and financial information as Wall Street tenets would predict, and to see whether the financial performance of these companies provides any lessons for practicing plastic surgeons. In efficient markets, the assumptions on which independent financial analysts base their company sales and earnings projections are clinically reasonable, the volatility of a company's stock price does not irrationally differ from that of its industry sector, and the buy/sell recommendations of analysts are roughly congruent. For the companies in this study, these key financial parameters were compared with a benchmark index of 69 biotech companies of similar age and annual revenues (Student's t test). Five bioengineered skin companies were included in the study. Analysts estimated that each company would sell its product to between 24 and 45 percent of its target clinical population. The average stock price volatility was significantly higher for study companies than for those in the benchmark index (p < 0.05). Similarly, buy/sell recommendations of analysts for the study companies were significantly less congruent than those for the benchmark companies (p < 0.05). These results indicate clinically unrealistic projections for market penetration, significantly high price volatility, and significantly high discordance among professional analysts. In all cases, the market is inefficient-an unusual finding on Wall Street. A likely explanation for this market failure is a cycle of poor clinical correlation when assigning sales projections, which in turn leads to price volatility and discordance of buy/sell recommendations. This study's findings have implications for plastic surgeons who develop new technology or who participate in the equities markets as investors. Plastic surgeons who develop new medical devices or technology cannot universally depend on the market to drive clinically reasonable financial performance. Although inflated sales estimates have benefits in the short term, failure to meet projections exacts severe financial penalties. Plastic surgeons who invest in the stock market, because of their unique clinical experience, may sometimes be in the position to evaluate new technologies and companies better than Wall Street experts. Well-timed trades that use this expertise can result in opportunities for profit.

Differential expression of matrix metalloproteinases and their tissue-derived inhibitors in cutaneous wound repair.

Wound extracellular matrix is a key regulator of cell adhesion, migration, proliferation, and differentiation during cutaneous repair. The amount and organization of normal wound extracellular matrix are determined by a dynamic balance among overall matrix synthesis, deposition, and degradation. Matrix metalloproteinases (MMPs) are one family of structurally related enzymes that have the collective ability to degrade nearly all extracellular matrix components. The MMPs are broadly categorized into collagenases, gelatinases, stromelysins, and membrane-type MMPs by their substrate specificity. The aim of this study was to characterize the temporal changes in mRNA profiles for rat collagenase [matrix metalloproteinase-1 (MMP-1)], gelatinase A (MMP-2), matrilysin (MMP-7), gelatinase B (MMP-9), and membrane type 1-MMP (MT1-MMP), as well as tissue inhibitor of metalloproteinases-1 (TIMP-1), TIMP-2, and TIMP-3 during the inflammatory, granulation, and early remodeling phases of excisional skin repair. Eight full-thickness skin wounds were made on the backs of each rat (7-mm2 wounds; 16 rats; n = 128 wounds). Two animals at a time were reanesthetized, and all eight wounds on each animal were excised at 12 and 24 hours and at 2, 3, 5, 7, 10, and 14 days after injury. Six wounds from each animal were excised for RNA isolation, whereas two wounds were excised for histology. Controls consisted of nonwounded skin from identical locations in four animals. Total RNA from each time point was isolated and relative mRNA quantitation performed by using reduced-cycle reverse transcription-polymerase chain reaction. Correct polymerase chain reaction product amplification was confirmed by probing the blotted polymerase chain reaction product with a 32P-labeled oligonucleotide specific for a given MMP or TIMP. We demonstrated that the majority of MMP and TIMP mRNA induction and peak expression coincided temporally with the well-characterized inflammatory and granulation stages of repair. In conclusion, there is a distinct pattern of MMP and TIMP expression during normal excisional wound repair.

Learning curve of microvascular venous anastomosis: a never ending struggle?

In this study, a simple protocol based on the rat femoral venous anastomosis was established to provide a quantitative representation of the progress. The learning curve is based on the patency rate in each consecutive group of five anastomoses. Two groups of surgeons were observed. The inexperienced group encountered a tough time in the first 25 anastomoses. However, the progress was fast and is represented by the steep slope of the curve. A plateau was reached whereby the avearge patency rate matches that of the experienced group. As expected, there was no learning curve for the experienced group. Despite every effort to attempt to maintain a perfect 100% patency on this model, the best achievable patency was only 88%. The results and its implication are discussed.

Reoperation after esophageal replacement in childhood.

BACKGROUND: Esophageal replacement is associated with significant morbidity that may lead to operative interventions. This study reviews the management and outcome of children who underwent reoperation after esophageal replacement. METHODS: Eighteen patients who underwent esophageal replacement from 1985 to 1997 were reviewed retrospectively. Ten patients underwent reoperation. Patient management, perioperative morbidity, and the dietary intake at follow-up were recorded for each patient. RESULTS: Of the reoperated patients, 7 had esophageal atresia, 2 had caustic ingestion, and 1 had achalasia. Nine patients received a colon interposition, and 1 received a reverse gastric tube as the initial esophageal replacement. Seven patients required revision of the anastomoses. Three patients required complex esophageal reconstruction: 1 underwent gastric transposition, 1 underwent free jejunal graft, and 1 underwent gastric transposition combined with free jejunal graft. Seven patients were eating well at follow-up. Two patients still required partial gastrostomy tube feeding. One patient died 6 months postoperatively from aspiration pneumonia. CONCLUSIONS: Esophageal replacement continues to be a challenging operation associated with significant complications. Most reoperative procedures were directed toward strictures and persistent fistulae. Complete graft failure can be managed by gastric transposition or free jejunal graft. Despite the perioperative morbidity, most patients have good functional outcome.

Downregulation of apoptosis-related genes in keloid tissues.

BACKGROUND: Physiologically programmed cell death or apoptosis occurs during the natural balance between cellular proliferation and demise. MATERIALS AND METHODS: We compared the expression of 64 apoptosis-related genes in keloids and normal scars to investigate the potential role of apoptosis in keloid formation. Two sets of mRNA were isolated from keloids excised from four previously untreated patients and four normal scar patients separately. Human cDNA arrayed hybridization was performed to compare the apoptosis-related gene expression between these two groups. In addition, TUNEL assays were performed to evaluate the percentage of apoptotic cells in keloids (center and periphery) versus normal scars. RESULTS: Eight of the sixty-four apoptosis-related genes studied were significantly underexpressed in keloid tissue. The underexpressed genes and their relative expression compared with normal scar were defender against cell death 1 (DAD-1) (34.1% of normal scar); nucleoside diphosphate kinase B (c-myc transcription factor) (24.7%); glutathione S-transferase (17.9%); glutathione S-transferase microsomal (28.1%); glutathione peroxidase (47.2%); tumor necrosis factor receptor 1-associated protein (TRADD) (51.0%); 19-kDa interacting protein 3 (NIP3) (36.0%); and cytoplasmic dynein light chain 1 (HDLC1) (47.7%). Spatial analysis of apoptosis using TUNEL assays revealed apoptosis indices of 0.83 for keloid periphery and 0.63 for keloid center. CONCLUSIONS: In this study we demonstrated underexpression of apoptosis-related genes in human keloid tissue and decreased apoptotic activity in fibroblasts derived from keloids versus normal scars. We hypothesized that keloid fibroblasts fail to undergo physiologically programmed cell death and, thus, continue to produce and secrete connective tissue beyond the period expected in normal scar formation, accounting for the progressive and hypertrophic nature of keloids. This mechanism leads to new possibilities for treatment of keloids through induction of apoptosis.

Total mandibular and lower lip reconstruction with a prefabricated osteocutaneous free flap.

Large, complex bony defects can be a vexing problem for the reconstructive surgeon, especially when standard donor sites are not available or do not provide sufficient tissue. Using the concept of flap prefabrication, we demonstrated in a single patient that (1) iliac crest bone chips and bone morphogenic protein in an alloplastic mandibular tray can ossify in a heterotopic location and (2) neovascularization sufficient to support a large, custom-designed bone graft occurs within a convenient "carrier" flap. Ultimately, the fields of angiogenesis and osteogenesis research could significantly contribute to the ability of the plastic surgeon to construct the "ideal" composite prefabricated flap for complicated reconstruction.

Cutaneous rat wounds express c49a, a novel gene with homology to the human melanoma differentiation associated gene, mda-7.

We have used DD-PCR (differential display-polymerase chain reaction) to identify new genes that are over- or underexpressed during wound repair. DD-PCR performed on excisional wounds identified the expression of rat c49a. Cloning and sequence analysis of the rat c49a gene revealed high homology to a novel human melanoma differentiation associated gene, mda-7. The human mda-7gene isolated from melanoma cell lines, has been linked with human melanoma differentiation, and growth suppression. Moreover, transfection of human mda-7 constructs into human tumor cells suppresses the growth and colony formation of tumor cells from diverse origins. To confirm and relatively quantitate expression of rat c49a gene during repair, specific primer, reduced cycle RT-PCR (reverse transcription-PCR) was performed. RT-PCR showed an approximately 9 to 12-fold elevation of rat c49a mRNA at 12 h to 5 days above nonwounded controls that gradually decreased to approximately 1.5 to 3-fold by day 14. Cloning and sequence analysis of the entire 1200 base pair c49a gene product showed 78% nucleotide homology to human mda-7. Immunohistochemistry studies localized rat C49A expression primarily to fibroblast-like cells at the wound edge and base. The marked up-regulation of rat c49a transcripts during the inflammatory and early granulation tissue phases of wound repair where cellular processes such as re-epithelialization, angiogenesis, and fibroplasia predominate--suggest that c49a is associated with proliferation of fibroblasts in wound healing.

Pricing strategy for aesthetic surgery: economic analysis of a resident clinic's change in fees.

The laws of microeconomics explain how prices affect consumer purchasing decisions and thus overall revenues and profits. These principles can easily be applied to the behavior aesthetic plastic surgery patients. The UCLA Division of Plastic Surgery resident aesthetics clinic recently offered a radical price change for its services. The effects of this change on demand for services and revenue were tracked. Economic analysis was applied to see if this price change resulted in the maximization of total revenues, or if additional price changes could further optimize them. Economic analysis of pricing involves several steps. The first step is to assess demand. The number of procedures performed by a given practice at different price levels can be plotted to create a demand curve. From this curve, price sensitivities of consumers can be calculated (price elasticity of demand). This information can then be used to determine the pricing level that creates demand for the exact number of procedures that yield optimal revenues. In economic parlance, revenues are maximized by pricing services such that elasticity is equal to 1 (the point of unit elasticity). At the UCLA resident clinic, average total fees per procedure were reduced by 40 percent. This resulted in a 250-percent increase in procedures performed for representative 4-month periods before and after the price change. Net revenues increased by 52 percent. Economic analysis showed that the price elasticity of demand before the price change was 6.2. After the price change it was 1. We conclude that the magnitude of the price change resulted in a fee schedule that yielded the highest possible revenues from the resident clinic. These results show that changes in price do affect total revenue and that the nature of these effects can be understood, predicted, and maximized using the tools of microeconomics.

The financial environment of aesthetic surgery: results of a survey of plastic surgeons.

To gather information about aesthetic surgery's current practice structures, competitive environment, patient price sensitivity, and marketing and practice development requirements, a two-page survey was developed and mailed to all 1180 members of the American Society for Aesthetic Plastic Surgery. A total of 632 surveys were returned (response rate of 54.5 percent). Most aesthetic plastic surgeons said they were in solo practice (63.3 percent). More than two-thirds described the marketplace as "very competitive," with 59 percent reporting 25 or more surgeons offering aesthetic surgery in their area. They estimated their patients' average income at $62,800. Nearly all plastic surgeons labeled their patients as "moderately price sensitive" (62.3 percent) or "very price sensitive" (30.6 percent). Similarly, 23.2 percent estimated that they had lost 20 or more patients within the last year for reasons of price. Practice development and marketing efforts represented an average of 7.3 percent of plastic surgeons' working time. Parameters associated with a high percentage of time devoted to these activities were solo practice, percentage of revenue from aesthetic surgery greater than 50 percent, a practice environment designation of moderately or very competitive, and ten or more area surgeons offering aesthetic surgery (p < 0.05). High patient income led to only slight decreases in price sensitivity and did not significantly reduce the amount of time spent on marketing and practice development. Although the rest of the healthcare industry has undergone a period of consolidation, aesthetic surgeons have been able to resist these changes. The results of this survey suggest that the fragmented nature of the aesthetic surgery industry is associated with additional burdens on plastic surgeons. As the aesthetic surgery market becomes more competitive, plastic surgeons may benefit from consolidation to reduce costs and maximize efficiency.

The effect of increased consumer demand on fees for aesthetic surgery: an economic analysis.

Economic theory dictates that changes in consumer demand have predictable effects on prices. Demographics represents an important component of demand for aesthetic surgery. Between the years of 1997 and 2010, the U.S. population is projected to increase by 12 percent. The population increase will be skewed such that those groups undergoing the most aesthetic surgery will see the largest increase. Accounting for the age-specific frequencies of aesthetic surgery and the population increase yields an estimate that the overall market for aesthetic surgery will increase by 19 percent. Barring unforeseen changes in general economic conditions or consumer tastes, demand should increase by an analogous amount. An economic demonstration shows the effects of increasing demand for aesthetic surgery on its fees. Between the years of 1992 and 1997, there was an increase in demand for breast augmentation as fears of associated autoimmune disorders subsided. Similarly, there was increased male acceptance of aesthetic surgery. The number of breast augmentations and procedures to treat male pattern baldness, plastic surgeons, and fees for the procedures were tracked. During the study period, the supply of surgeons and consumer demand increased for both of these procedures. Volume of breast augmentation increased by 275 percent, whereas real fees remained stable. Volume of treatment for male pattern baldness increased by 107 percent, and the fees increased by 29 percent. Ordinarily, an increase in supply leads to a decrease in prices. This did not occur during the study period. Economic analysis demonstrates that the increased supply of surgeons performing breast augmentation was offset by increased consumer demand for the procedure. For this reason, fees were not lowered. Similarly, increased demand for treatment of male pattern baldness more than offset the increased supply of surgeons performing it. The result was higher fees. Emphasis should be placed on using these economic relationships to expand the demand for aesthetic surgery.

The effect of increased plastic surgeon supply on fees for aesthetic surgery: an economic analysis.

The size of the plastic surgery workforce has important effects on the financial environment of the specialty. Economic theory predicts that increasing the area supply of surgeons performing aesthetic surgery will result in lower fees for their services. This study tested that theory in the actual aesthetic surgery marketplace. The study examined the ratio of plastic surgeons to the general population of several states. It then traced the aesthetic surgery fees resulting from different densities of area plastic surgeons. This information was economically analyzed to project the fee effects of possible future changes in the number of practicing plastic surgeons. For the states of New York, California, and Texas, there is a proportional decrease in fees as the density of plastic surgeons increases. For example, New York has 34 percent more plastic surgeons proportionally than Texas, and its fees are 30 percent lower in real dollars. Economic analysis can project the fee effects of changing the supply of surgeons performing aesthetic surgery. The analysis reveals that a 30 percent national increase in the supply of plastic surgeons would lower fees by approximately 32 percent. Similarly, if the number of plastic surgeons increases by 50 percent, fees will decrease by approximately 53 percent. However, these fee effects can be mitigated by expanding the demand for aesthetic surgery. In conclusion, the size of the plastic surgery workforce has profound effects on the fees paid for aesthetic surgery, and the magnitude of these effects can be understood, predicted, and optimized using the tools of economics.

Superior gluteal free flap breast reconstruction.

The authors substantial experience with the superior gluteal free flap for breast reconstruction indicates that this is a more difficult but important free flap for breast reconstruction. Compared with the standard transverse rectus abdominis myocutaneous (TRAM) free flap, it is a much less forgiving operation with many specific technical details. With careful attention to details on flap design, recipient vessel selection anastomsis, and flap insetting, the success rate and morbidity of the gluteal flap operation are highly acceptable. For patients unsuitable for the TRAM flap for autologous tissue reconstruction, this is a very valuable alternative. It can achieve some spectacular results in breast reconstruction in terms of volume, replacement, and projection--even in very thin patients.

Simultaneous bilateral breast reconstruction with the transverse rectus abdominus musculocutaneous free flap.

OBJECTIVE: The purpose of the study was to assess the results and morbidity associated with simultaneous bilateral TRAM free flap breast reconstruction and describe refinements in its surgical technique. SUMMARY BACKGROUND DATA: Bilateral prophylactic total mastectomies might be an agreeable option for those patients at highest risk for breast cancer if autogenous tissue breast reconstruction could be performed with reasonable technical ease and acceptable morbidity. However, some surgeons harbor reservations regarding the extensiveness of the surgery, the associated morbidity, and the aesthetic quality of the resulting outcome. METHODS: A multicenter retrospective review of clinical experience with 120 consecutive patients who underwent 240 simultaneous bilateral TRAM free flap breast reconstructions was developed. RESULTS: The average operating time, including the time required for the breast ablative portion of the procedures, was 8.6 hours. The average length of hospitalization was 7.6 days. However, for the last 40 patients, these figures were reduced to 7.1 hours and 6.1 days, respectively. Nonautologous blood transfusions were needed in 33 cases (28%), but only 1 was required in the last 40 patients. Thromboses developed in six of 240 flaps (2.5%): 4 were arterial and 2 were venous. Re-exploration allowed us to restore circulation in five flaps, whereas one flap was unsalvageable and was replaced successfully with an alternate flap. An uncomplicated deep vein thromboses developed in one patient with a history of recurrent deep vein thromboses that had no adverse effect on her outcome. Minor complications developed in 18 patients (15%) (e.g., hematoma, partial wound necrosis, wound infection, or prolonged postoperative ileus) that did not affect the long-term outcome. Fourteen patients (11.6%) had abdominal wall weakness or hernias. Follow-up time averaged 37.2 months (range, 14-62 months). On last follow-up, patients' self-reported overall satisfaction with the procedure was 56% excellent, 40% good, and 4% fair. CONCLUSIONS: Simultaneous bilateral free flap reconstruction is technically feasible with a high rate of success and an acceptable morbidity. When performed by experienced surgeons, bilateral prophylactic total mastectomies combined with simultaneous bilateral TRAM free flap reconstruction may provide an adequate surgical option with aesthetically acceptable results for patients at high risk for breast cancer.

Circumferential wrapping of a flap around a scarred peripheral nerve for salvage of end-stage traction neuritis.

Nine patients with chronic severe pain due to end-stage traction neuritis of an intact peripheral nerve underwent external neurolysis and epineurectomy or epineurectomy and internal neurolysis followed by circumferential wrapping of the involved segment of nerve with a pedicle flap or free flap consisting of either subcutaneous fat tissue, fascia, or muscle. Seven patients (77%) followed for between 1 and 5 years had substantial relief of pain. Two patients (22%) had no decrease in their pain at all. Circumferential wrapping may cushion the nerve from external pressure on the overlying skin, may isolate the nerve from the traction forces of adjacent moving tendons to allow improved gliding of the nerve, and may promote revascularization of a scarred nerve. This surgery may be indicated for patients with persistent pain following multiple carpal tunnel or cubital tunnel surgeries.

TRAM flaps in patients with abdominal scars.

Of 114 patients who had TRAM flap breast reconstruction, 46 (40 percent) had preexisting abdominal surgical scars. Sixty-six free TRAM flaps and 9 pedicled TRAM flaps were performed in the 46 patients. The records were analyzed to determine what impact, if any, abdominal scars had on postoperative complications. There were no reconstructive failures or significant (>25 percent) flap losses. Eight minor complications occurred in 7 patients (15 percent). The incidences of abdominal-wall weakness (4.3 percent), partial flap loss (4.3 percent), minor fat necrosis (4.3 percent), and donor-site wound problems (4.3 percent) were acceptable. Subcostal scars and multiple abdominal scars were found to predispose to skin complications. Right lower paramedian scars precluded free TRAM flaps because of damage to the inferior epigastric vessels in three of three patients. Both obesity (p = 0.003) and smoking (p = 0.05) were associated with a greater risk of wound-healing complications. We conclude that with certain technical modifications, TRAM flap reconstruction is a safe and effective procedure in patients with abdominal scars.
