Chest reconstruction after sternal infection
October 18, 2009
One of the devastating complications one can have after cardiac bypass surgery is a sternal infection. It usually occurs in patients that have multiple other medical issues (i.e. obesityy, diabetes, etc). The range of infection can be minor involving the skin/subcutaneous layer or major involving the sternum and surrounding tissues. Frequently plastic surgeons are asked to assist our cardiac surgeon colleagues in evaluating sternal wounds. Once the initial infection is controlled with irrigation and debridement a wound VAC dressing is used to help decrease wound dressing changes, promotes granulation tissue, allows for smaller wounds to heal with secondary intention, and decreases edema in the tissues, which may allow the possibility for sternal salvage with rigid fixation. and promote wound healing. In a severe wounds that don’t have properly healing bone, the sternum has to undergo debridement and plating to allow adequate healing. Oftentimes, some form of vascularized tissue is placed over the bone to encourage healing. In this case, the cardiac surgeons opted to place an omental flap to cover the bone and give it a chance to heal. The omentum has been used effectively for many years in the management of sternal wound dehiscence. Its broad, pliable, fatty nature allows it to conform and seal off the deep recesses in large wounds. Its rich abundant source of lymphatics also aids in clearing infection.
After several weeks the bone healed and the patient was left with a gaping hole in the center of the chest. The omentum was not able to completely fill up the wound. After the plating mechanism was removed we opted to use bilateral pectoralis muscle advancement flaps to cover the defect. This type of flap has a dual blood supply (thoracoacromial pedicle and internal mammary perforators). The internal mammary arteries were used for the bypass procedure, so we advanced the muscle after detaching it from the clavicle and humerus. Both pectoralis muscles were needed to cover the defect. Fortunately we were also able to advance the skin and the patient was left with a midsternal incision similar to his previous CABG operation.
Unfortunately, this patient had a prolonged hospital stay due to this complication. We as surgeons do everything we can to prevent infection. We train many years to perfect meticulous surgical techniques / procedures, optimize operating room conditions (oxygen delivery, temperature), and ICU recovery (adequate glucose management). However, we have no control over certain issues pertaining to patient comorbities (i.e. morbid obesity, diabetes, chronic lung disease, renal failure). Often we are faced with treating these patients because no one else will. Many studies have shown high-risk patients (multiple comordities) generally have higher complication rates.
To compound this problem even more, new medicare regulations have been adopted to reduce certain hospital infections. In October 2008, the Centers for Medicare and Medicaid
Services (CMS), stated payments will be withheld from hospitals for care associated with treating certain catheter-associated urinary tract infections, vascular catheter-associated infections, mediastinitis after coronary artery bypass graft (CABG) surgery, and five other medical errors
unrelated to infections (bed sores, objects left in patients’ bodies, blood incompatibility, air embolism, and falls). We as health-care providers can control some of these complications. But realistically, it may come at a cost…namely only treating healthy low-risk patients to minimize comorbid-related complications. Describing the various nuances related to each comorbidity and complication is beyond the scope of this blog entry, but may serve further discussion.
The bottom-line, we are left with the CMS decision and are likely to have many similar regulations when “Obama-care” takes center stage. It behooves us as plastic surgeons to look into hospital cost-saving measures. One can invision several studies where performing certain plastic surgery procedures can actually save hospital and patient costs. Maybe performing early pectoralis flap surgery for sternal infection will be shown to reduce hospital costs….stay tuned.

We as residents meet monthly at a predetermined destination to engulf ourselves in the bible of plastic surgery literature…Plastic and Reconstructive Surgery (PRS). Yesterday our meeting occurred at the esteemed Washington-Duke hotel study. We sat around a fireplace in comfy leatherback chairs sipping wine, scotch, and (yeah a bit snuddy…but very fun!) and went through several articles in September PRS journal. Our administrative chief resident assigns articles to each resident prior to our meeting. We then critically read the article and summarize its contents to everyone. Our faculty, who host these events for us, chime in on particular articles that peak their interest. They offer insight into various authors perspectives and integrate their teaching into intellectual morsels based on personal clinical, surgical, philosophical experiences. It’s a chance for us to keep up to date on the latest in plastic surgery so we can apply new, sometimes evidence-based decisions to our Duke patients.

Attacking Wrinkles for the First Time
September 11, 2009
My first “botox party/teaching session” occurred this week at the aesthetic center. We organize weekly plastic surgery-oriented teaching sessions that give us insight into various topics. This week just happened to involve cosmetic anti-wrinkle treatment. We received a formal teaching of various botulism toxin injections followed by the ever popular skill session. Numerous employees from the aesthetic center whole-heartedly volunteer to have us rid them of their glabellar and forehead wrinkles and whatever else they find distracting. All injections were supervised by our faculty who offered assistance with injection location.
The product we used, named Dysport (abotuliniumtoxin A) is made by Tercica, a subsidiary of Ipsen. A head-to-head competitor with Botox, made by Allergan. Both products are a neurotoxin that inhibits the release of acetylcholine and results in the flaccid paralysis of the affected muscles thus smoothing the overlying skin. Dysport claims that its molecular structure varies from Botox in a way that allows its effects to start earlier (1-2 days) and last longer (greater 3months). Dysport may last longer and may cost less since more dilution can be done in the reconstitution process. Others say the two substances are not interchangeable since Dysport may have a tendency to disperse into surrounding muscles and affect their function in a different way than Botox.
Prior to this injection session my only exposure to botulinium toxin injection was in general surgery where we used it to help with anal fissure issues. We would use a minute amount (maybe 50 units) and I can remember the nursing OR staff buzzing around us after the case wanting us to inject their faces with the left- over solution. We opted each time to throw it out and recieved flack everytime. Now, fast forward several months later to the present. I have a similar vial of botulinium toxin nectar and everybody swarms around wanting the last nanoliter of product injected into them. Past botulism parties were not as well attended do to last minute scheduling issues. For better or worse residents were left injecting one another. Fortunately, this session was well attended and I can tell you now that I prefer to inject the face rather than the anus….ohhh plastic surgery is the place for me.

Alloderm and Breast Reconstruction
August 19, 2009
Today was my first exposure using Alloderm as a mode of immediate breast reconstruction after bilateral mastectomy. One breast had already received neoadjuvant radiation. During preoperative evaluation with my staff, the patient decided to have bilateral tissue expanders placed with Alloderm instead of other reconstructive options (i.e. lattisimus dorsi pedicled flap). Alloderm is a biologic mesh made from donated human skin (dermis) and is processed in such a way to remove all cellular content leaving a matrix for tissue ingrowth to occur. The Alloderm is positioned in the inferior aspect of the breast pocket and secured to refashion the inframammary fold (bottom of the breast) and allow the implant to sit in its pocket. This mesh reinforces the surrounding irradiated skin from underneath and decreases the incidence of skin loss and resulting implant infection. You can think of it as an expensive implant pita pocket that allows fibroblast and vascular regeneration. The cost of our 12 x 12 in mesh we used today ranges $3000-4000. Per LifeCell, the manufacture of Alloderm, the cost is justified by the extensive processing that goes into removing cells and leaving this valuable matrix. Nevertheless, I’ve found another use for biologic mesh besides using it to repair contaminated abdominal hernias.
During the process of inserting a breast prosthesis into the native breast tissue I have found a new meaning to infection paranoia. After insetting the Alloderm mesh and partially fixing it to the pectoralis muscle we placed breast tissue expanders that will be used to increase the space for eventual breast implant placement. Before handling any implant device, the surgeon goes through a ritual of reprepping the incision again with betadine (keep in mind the whole operative field has remained sterile with no contamination), changing into new surgical gloves, using completely new surgical instruments that have not touched the already sterile field, and irrigating the breast cavity with betadine solution. Finally, when the stars have aligned perfectly, the implant is placed into the breast cavity without touching anything except the extremely sterile gloved hands of the surgeon. I can appreciate implant infection is disasterous. Now one can see all the trouble we go through to maintain such a sterile environment for the implant. Interestingly enough, implant manufacturers don’t recommend using betadine near the implant, but plastic surgery literature supports use of it due to a decrease in capsule contraction (i.e. decreased infection rate) plus it minimizes staph epidermidis colonization.

Besides cosmetic surgery, if there is one area that separates plastic surgery from all other surgical specialities it is the use of flap reconstruction. In chronically infected or poorly healing wounds, changing its environment by bringing it new well-vascularized tissue with a flap is a cornerstone of solving many difficult wound problems. The most everyday use of flap reconstruction would undoubtably be breast reconstruction.
It is one concept in
What I love most about flap reconstruction is that it requires functional or a dynamic knowledge of anatomy, not just a static picture or diagram. Rote memorization of where the anatomical parts are is not nearly enough. You must go deeper into the decriptions in the classic Gray’s anatomy textbook to understand blood vessels, nerves, and the different anatomic planes and layers. Research in plastic surgery continues to unravel the intricacies of how vascular inflow and egress out of ‘flapped’ tissues works and how it may be capable of being pharmacologically manipulated. Gray, and particularly William Harvey, would be stunned by today’s understanding that it is not as simple as pipes going in and coming out.
Journal clubs have been a part of surgical training almost since such formalized education began. While initialing started as a method to discuss the few journals that existed at the time, the sheer numbers of surgery journals that are published today dwarfs the limited time than any journal club can hope to review. Plastic Surgery is no different with at least four major journals of which PRS (Plastic and Reconstructive Surgery) remains the most widely read. This results in well over a hundred articles per month for any plastic surgery trainee to potentially review. With the demands of residency, one is most likely to only have the time to scan the indexes and may be able to pick out a handful to actually read.
Some journal clubs are very structured, while others are very relaxed. Perhaps the influence of good food or a little alcohol makes for a more open mind. That has been the debate of educators for centuries. Whether it be at the medical library, a staff physician’s house or at a local restaurant, this infrequent but valuable education endeavor will live on in plastic surgery. I suspect at some point, however, that the journal club concept will have to go digital…perhaps migrating toward an online chat room approach or even an iPhone app! In this rapidly expanding digital age, plastic surgery journal clubs could easily become an across the country online experience between many different training programs.
Since its introduction in 2002,
As one emerges from any prior surgical training (which is a prerequisite for plastic surgery), the single greatest change that must occur is….how to think like a plastic surgeon. Such a premise raises the questions of why is this necessary and what does that mean? After all, surgery is surgery and one’s prior training already has one thinking like a surgeon.
