The bipedicled osteocutaneous scapula flap : a new subscapular system free flap

Thirty-six adult dissections (14 cadaver and 22 operative) demonstrate the constant presence of the angular branch of the thoracodorsal artery as a vascular pedicle to the inferior pole of the scapula. This vessel originated in all cases just proximal or distal to the serratus branch of the thoracodorsal artery and arborized to the periosteum 6 to 9 cm from the bony branch of the circumflex scapular artery. In eight patients, scapular osteocutaneous flaps were raised preserving the angular branch and the circumflex scapular artery and dissecting up to the subscapular vessels. In all cases, bone was independently perfused by the angular branch. In all six cases where the angular branch was the sole supply to bone, technetium-99m scans demonstrated perfusion. Addition of this vascular pedicle to scapula bone allows two separate bone flaps with one microanastomosis and provides a longer arc of rotation between skin supplied by the circumflex scapular artery and bone. Donor-site morbidity was no greater than with the standard scapula flap.

Single-stage Management of 74 Consecutive Sternal Wound Complications with Pectoralis Major Myocutaneous Advancement Flaps

The optimal management of sternal wound complications remains controversial. Since 1985, we have utilized a combination of immediate, aggressive debridement with simultaneous repair using bilateral pectoralis major myo-cutaneous advancement flaps, regardless of the degree of infection. As compared with the use of distant pedicled muscle flaps or pectoralis major turnover flaps, the management of complicated sternal wounds with immediate pectoralis major myocutaneous advancement flaps provides an effective yet simpler, quicker method of management with improved aesthetic results. In addition, basing the pectoralis major myocutaneous flaps on the thoracoacromial arteries eliminates the need for intact internal mammary arteries, valuable since the latter are increasingly used for coronary grafts.Seventy-four consecutive patients, 17 (23 percent) of whom were immunosuppressed heart transplant recipients, have been managed with this procedure. There were no intraoperative deaths. The 30-day perioperative mortality rate was 9 percent (7 of 74), with only 1 death related to persistent sepsis. The morbidity rate was 39 percent, with the most common complication being seroma managed by needle aspiration (18 of 74, 24 percent). The aesthetic and functional results have been uniformly excellent. (Plast. Reconstr. Surg. 93: 1433, 1994.)

Immediate breast reconstruction in patients with locally advanced disease.

Immediate breast reconstruction for patients with early-stage disease is well established. This study evaluates a consecutive series of 22 patients with locally advanced disease (stage IIB or III) who underwent mastectomy and immediate breast reconstruction. All patients received several cycles of neoadjuvant chemotherapy (average, 3.5 cycles) followed by completion of chemotherapy beginning approximately 3 weeks following surgery. The perioperative morbidity was 14% and no patient suffered a delay in the resumption of chemotherapy. Patients have been particularly grateful about being offered reconstruction in this setting. Our preliminary results with this technique have been encouraging and further study is warranted.

The use of magnetic resonance angiography in vascularized groin lymph node transfer: an anatomic study.

Vascularized groin lymph node transfer (VGLNT) has been successfully used to treat lymphedema. However, lack of familiarity with the inguinal node anatomy and concerns regarding donor site morbidity have limited its widespread use. The purpose of this study was to use magnetic resonance angiography (MRA) to clarify the inguinal anatomy and provide a reliable method for identifying the location of the superficial transverse inguinal lymph nodes. In this study MRA was used to evaluate the superficial inguinal lymph nodes in 117 patients. Coordinates of lymph nodes were plotted relative to an axis from the anterior superior iliac spine (ASIS) to the pubic tubercle (PT). The nodes were also plotted relative to the superficial circumflex iliac vein (SCIV) and superficial inferior epigastric vein (SIEV). A total of 1,938 lymph nodes were identified. These lymph nodes were concentrated on one-third the distance from the PT toward the ASIS and 3 cm perpendicularly below this line. About 67% of the superficial inguinal nodes were located within the bifurcation of the SIEV and SCIV. The results from this study provide useful guidelines for locating lymph nodes targeted for VGLNT.

Frey's syndrome: prevention with temporoparietal fascial flap interposition.

The recent trend in management of Freys syndrome has been the use of prophylactic procedures performed at the time of parotidectomy to prevent its symptoms postoperatively. An additional benefit of this approach is the prevention of the typical cheek contour deformity after parotidectomy. We reviewed our experience with interposition of a vascularized temporoparietal fascial flap between the parotid bed and overlying skin immediately after complete superficial parotidectomies to prevent Freys syndrome and contour defects. The results of seven consecutive attempts revealed it to be an effective technique, achieving both goals in all patients with minimal morbidity.

Nipple-areola reconstruction with intradermal tattoo and double-opposing pennant flaps.

Reconstruction of the nipple—areolar complex is an important part of postmastectomy breast reconstruction. Intradermal tattooing is effective for creating areolar pigmentation and is simpler than skin grafting. However, a simple method for the construction of a normal nipple using local tissues remains a challenge. Several techniques achieve long-term nipple projection but at the expense of complicated flap design, multidirectional scars, and often a need for skin grafting to obtain a uniform-appearing areola. Our one-stage method of nipple—areola reconstruction uses intradermal tattooing for pigmentation and double-opposing pennant flaps for nipple reconstruction. The entire procedure is simple and fast, routinely performed in <30 minutes under local anaesthesia in the office. From September 1989 to March 1992 we performed 102 reconstructions. The method produces a realistic appearing nipple. We have had no flap necrosis.Hugo NE, Sultan MR, Hardy SP Nipple—areola reconstruction with intradermal tattoo and double-opposing pennant flaps.

Reconstructive surgery of the pelvis after surgery for rectal cancer.

The role of the reconstructive surgeon has increased with an increasingly aggressive surgical approach to locally advanced rectal carcinoma. Multiple options exist for pelvic floor reconstruction. Muscle and myocutaneous flaps for pelvic-floor reconstruction provide well vascularized tissues which may also serve as a biologic spacer. Flaps help to prevent post-radiation fistulae, small bowel obstruction, and pelvic sidewall adherence; flaps also may serve as a barrier to radiation injury. Often a more stable perineal wound closure is achieved. In cases that involve vaginal resection, flaps make neo-vaginal reconstruction possible. Pre-operative consultation with the reconstructive surgeon allows planning of complex, multi-disciplinary procedures, and facilitates patient understanding of the proposed procedure.

Comparison of irradiated versus nonirradiated DIEP flaps in patients undergoing immediate bilateral DIEP reconstruction with unilateral postmastectomy radiation therapy (PMRT).

IntroductionPatients with node positive or locally advanced breast cancer desiring deep inferior epigastric perforator (DIEP) flap reconstruction frequently require postmastectomy radiation therapy (PMRT). To avoid the deleterious effects of PMRT, surgeons will often delay reconstruction until after PMRT is complete. Drawbacks to this approach include additional surgery, recuperation, cost, and an extended reconstructive process. Even if a tissue expander is used to preserve the skin envelope during irradiation, the post-PMRT breast pocket is often distorted or constricted necessitating some skin replacement, resulting in a compromised aesthetic outcome. Therefore, a systematic approach to mitigate the deleterious effects of PMRT was developed, and primary DIEP flap reconstruction was offered to patients requiring PMRT. This study evaluates the outcome of this approach in a cohort of patients undergoing immediate bilateral DIEP flap reconstruction with unilateral PMRT, allowing comparison between irradiated and nonirradiated flaps. MethodsOne hundred twenty-five patients who underwent immediate DIEP reconstruction between 2009 and 2011 were identified. Eleven consecutive patients had bilateral DIEP reconstructions by a single surgeon and received unilateral PMRT. Preoperative, intraoperative, and postoperative steps were taken in all patients to ensure flap vascularity, prevent uncontrolled contracture, and limit radiation damage to the breast mound. Results were documented photographically and the irradiated and nonirradiated breasts were compared. The complication rates, incidence of clinically significant fat necrosis, and need for reoperation were examined. ResultsMedian follow-up was 18 months (range, 8–21 months). Complications were minor and did not require readmission to the hospital or reoperation. There was no incidence of clinically significant fat necrosis in either the irradiated or nonirradiated DIEP flaps. Four operative revisions for breast symmetry were required in 3 of 11 patients. Aesthetic outcomes were deemed satisfactory in all patients. ConclusionsPrimary reconstruction with DIEP flaps can be performed successfully in patients who require PMRT if steps are taken to ensure flap vascularity, minimize fibrosis, optimize contour, and modulate radiation dosing.

Factors influencing incidence and type of postmastectomy breast reconstruction in an urban multidisciplinary cancer center.

Background: On January 1, 2011, New York State amended the Public Health Law to ensure that patients receive “information and access to breast reconstruction surgery.” The purposes of this study were to investigate the early impact of this legislation on reconstruction rates and to evaluate the influence of patient variables versus physician variables on the incidence and type of breast reconstruction performed. Methods: A retrospective study was conducted on all patients who underwent mastectomy between January 1, 2010, and December 31, 2011. Reconstruction rates were analyzed in relation to timing of legislation, breast surgeon variables, plastic surgeon faculty status, type of reconstruction, and patient variables. Results: Two hundred fifty-eight patients met inclusion criteria. The overall reconstruction rate was 56.59 percent. There was no statistically significant increase in reconstruction rate after the 2011 legislation (OR, 0.45; p = 0.057). Patients whose breast surgeon was female were more likely to undergo reconstruction (OR, 5.17; p = 0.001). Patients who were Asian (OR, 0.22; p = 0.002), older than 60 years (OR, 0.09; p = 0.001), or had stage 3 and 4 cancer (OR, 0.04; p = 0.03) were less likely to undergo reconstruction. Patients reconstructed by a hospital-employed plastic surgeon were significantly more likely to undergo autologous versus implant reconstruction (OR, 6.85; p = 0.001) and to undergo microsurgical versus nonmicrosurgical autologous reconstruction (78.2 percent versus 0 percent; p = 0.001). Conclusions: Breast surgeon sex and plastic surgeon faculty status were the factors that most affected the rate and type of reconstruction, respectively. Legislation mandating the discussion of breast reconstruction options had no impact on reconstruction rate. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, II.

Laparoscopic Harvesting of Jejunal Free Flaps

We studied the safety and efficacy of laparoscopic jejunal free flap harvesting with total intracorporeal small-bowel anastomosis in an animal model. Eight dogs underwent laparoscopic resection of 8 to 15 cm of jejunum with endoscopic GIA anastomoses and jejunal segment harvesting through the periumbilical laparoscopic port. In six animals, the harvested jejunum was implanted subcutaneously and revascularized by anastomosis of the mesenteric artery and vein to the femoral vessels. Both the microvascular and intracorporeal jejunal anastomoses were studied at 10 days. Mean laparoscopic operative time was 2.9 hours, with the last five procedures all completed in fewer than 2 hours. Mean ischemic time was 1.9 hours. The laparoscopically performed small-bowel anastomoses were all successful. All dogs took regular diets within 1 day, with normal bowel function returning by the second day. Both clinically and histologically, the bowel wall and mesenteric vessels of all the segments harvested demonstrated no injury despite their laparoscopic harvest. Five of the free flaps remained fully viable at 10 days. One flap failed after prolapse of the flap resulting from inadequate fixation. Laparoscopic harvesting of the jejunal free flap is safe and efficacious and offers all of the potential advantages of laparoscopic abdominal surgery.
