Prospective computerized analyses of sensibility in breast reconstruction with non-reinnervated DIEP flap.

Background: The deep inferior epigastric perforator (DIEP) flap is considered the definitive standard for autologous breast reconstruction because of its ability to restore shape, its consistency, and its static and dynamic symmetry, but the degree of spontaneous sensory recovery is still widely discussed. To clarify the real need for sensitive nerve coaptation, return of sensibility in DIEP flaps was investigated using a pressure-specifying sensory device. Methods: Thirty consecutive patients with breast cancer scheduled for modified radical mastectomy, axillary node dissection, and immediate reconstruction with cutaneous–adipose DIEP flaps without nerve repair were enrolled in the study. Sensibility for one and two points, static and moving, was tested preoperatively on the breasts and abdomen, and postoperatively at 6 and 12 months on the DIEP flaps. A t test was used for comparison of paired data and to investigate which factors affected sensory recovery. Results: Preoperative healthy breast and abdomen pressure thresholds were lower for two-point than one-point discrimination and for moving discriminations compared with static ones at 6 and 12 months. Although they were significantly higher than those for contralateral healthy breasts (p < 0.05), pressure thresholds in DIEP flaps at 12 months were lower than at 6 months, showing a significant progressive sensory recovery (p < 0.05). At 12 months postoperatively, the best sensibility recovery was found at the inferior lateral quadrant, the worst at the superior medial quadrant. Age and flap weight were factors related to the performance of sensory recovery. Conclusions: DIEP flap transfer for immediate breast reconstruction undergoes satisfactory progressive spontaneous sensitive recovery at 6 and 12 months after surgery, and operative time spent dissecting sensitive perforator branches and their coaptation in recipient site could be spared.

Breast Implant-Associated Anaplastic Large Cell Lymphoma: Proposal for a Monitoring Protocol.

Background: The authors report four cases of breast implant–associated anaplastic large cell lymphoma (ALCL) from a single institution and propose a multidisciplinary protocol. Methods: From 2012 to 2014, four breast implant–associated ALCL cases were diagnosed. The authors performed the original operation, and no patients were referred to their practice. Cases 1, 2, and 4 were CD4+/CD30+/ALK− ALCL with previous textured-implant reconstruction, whereas case 3 was CD8+/CD30+/ALK− ALCL with previous polyurethane-implant augmentation. A retrospective study of all patients who underwent breast implant positioning was performed to identify any misdiagnosed cases. Results: Of 483 patients, 226 underwent reconstruction with latissimus dorsi flap and prosthesis, 115 had skin-sparing/nipple-sparing mastectomy and prosthesis, 117 underwent an expander/implant procedure, and 25 underwent breast augmentation. Fifty-eight cases (12 percent) underwent implant replacement for capsular contracture, 15 (3.1 percent) experienced late-onset seroma, and four (0.83 percent) had both capsular contracture and seroma. Seventy-seven symptomatic patients (16 percent) underwent surgical revision (capsulectomy/capsulotomy) and/or seroma evacuation. The second look on histologic specimens did not identify misdiagnosed cases. A multidisciplinary protocol for suspected implant-associated ALCL was established. Ultrasound and cytologic examinations are performed in case of periprosthetic effusion. If implant-associated ALCL is diagnosed, implant removal with capsulectomy is performed. If disseminated disease is detected through positron emission tomography/computed tomography of the total body, the patient is referred to the oncology department. Conclusions: A multidisciplinary protocol is mandatory for both early diagnosis and patient management. Until definitive data emerge regarding the exact etiopathogenesis of breast implant–associated ALCL, the authors suggest offering only autologous reconstruction if patients desire it.

Total breast reconstruction using the thoracodorsal artery perforator flap without implant.

Background: The thoracodorsal artery perforator flap was described mainly for partial breast reconstruction by Hamdi. The purpose of this article is to describe the use of the pedicled thoracodorsal artery perforator flap for total autologous breast reconstruction without using an implant. Methods: Between January of 2009 and December of 2011, seven patients underwent total breast reconstruction with a pedicled thoracodorsal artery perforator flap. The mean age of the patients was 53 years (range, 43 to 62 years), and the mean body mass index was 27 kg/m2 (range, 24 to 32 kg/m2). Results: The mean size of the harvested skin paddle was 23.7 × 8.8 cm2 (range, 15 × 7 cm2 to 39 × 14 cm2). The flaps were based on one to three perforators and successfully transferred with an average operative time of 3 hours. No seroma occurred at the donor site. Average hospital stay was 4 days (range, 3 to 6 days). At an average follow-up of 21.5 months, two patients underwent additional revisions using autologous fat grafting, with overall fat injection volumes of 240 and 280 cc, respectively. Conclusion: The pedicled thoracodorsal artery perforator flap offers an alternative for total autologous breast reconstruction in small to medium breasted patients when abdominal tissues are not available.

The axillary versus internal mammary recipient vessel sites for breast reconstruction with diep flaps: A retrospective study of 256 consecutive cases

The aim of this study is to present our experience on the use of various recipient sites for deep inferior epigastric perforator (DIEP) flap breast reconstruction and compare them by means of objective data. Two hundred fifty six DIEP flap breast reconstructions, performed between March 2004 and May 2011, were retrospectively analyzed. Only unilateral reconstructions were included in the study and divided into three groups depending on the recipient site choice: internal mammary vessels (IMV) (n = 52), thoracodorsal vessels (TDV) (n = 109), and circumflex scapular vessels (CSV) (n = 95). Clinical records of each patient were reviewed to acquire relevant data such as operative time, postoperative complications, and use of a second vein anastomosis. CSV group showed a statistically significant lower operative time (4.92 ± 0.54 hours) compared to TDV (5.67 ± 1.01 hours) and IMV groups (6.75 ± 1.09 hours) (P < 0.001). Second vein anastomosis was performed in 84 cases (88.1%) of CSV, in 85 cases (77.9%) of TDV, and in 18 cases (35.1%) of IMV groups (P < 0.001). No significant differences were observed among groups regarding risk factors and complications (P > 0.05). The axillary vessels seem to be the ideal recipient site because of reduced operative time and increased possibility to perform a second vein anastomosis. Among them, CSV can be safely used due to following advantages: easy dissection, larger vessel caliber, and optimal flap insetting. Moreover, their location does not expose them completely to radiotherapy consequences.

Permanent latissimus dorsi muscle denervation in breast reconstruction.

BackgroundA retrospective analysis of our series of denervated latissimus dorsi (LD) breast reconstructions showed a high incidence of postoperative LD contraction. Anatomical studies with a prospective clinical trial are set up to outline a successful denervation procedure. MethodsFifteen fresh cadavers were dissected to study thoracodorsal nerve course. Subsequently, 40 consecutive LD breast reconstructions were divided randomly in equal groups and underwent either distal (group A) or proximal (group B) nerve resection and clipping. The presence of postoperative contraction was evaluated clinically and instrumentally at 2-year follow-up. Statistical analysis of data was performed by Fisher exact test. ResultsCadaver dissections showed distal branching of thoracodorsal nerve in 20% of cases. Incidence of postoperative LD contraction was 35% (7/20) in group A and 0% in group B. A significantly lower rate of contraction in group B was demonstrated (P = 0.004). ConclusionsType B proximal nerve resection allows for effective denervation reducing incidence of postoperative contraction (P = 0.004).

Accidental injury of the latissimus dorsi flap pedicle during axillae dissection: types and reconstruction algorithm.

The intra‐operative latissimus dorsi (LD) pedicle damage during axillary lymph‐node dissection by the general surgeon is a rare complication leading to flap failure and poor outcomes. The authors present their experience on this topic and develop a classification of the thoracodorsal (TD) pedicle injuries and reconstruction algorithm. Pedicle damage of LD occurred in five cases, three of which were experienced during immediate breast reconstruction and two observed in patients who underwent prior surgery. In two cases the thoracodorsal vein (TDV) was damaged in its proximal segment, thus end‐to‐end anastomosis was performed between distal stump of TDV and circumflex scapular vein (CSV). In one case the TDV required simple microsurgical repair while in other two cases the severe damage of vein and artery required more complex surgical strategies in attempt to salvage the flap. Four cases completely survived with one case of rippling phenomenon. One case had partial flap necrosis that required subtotal muscle resection. Based on these cases, the authors have developed a reconstruction algorithm in attempt to repair LD pedicle damage while preserving breast reconstruction. Taking into account its anatomical conformation, TD pedicle injuries are classified in four different types and available options are suggested for all of them according to the anatomical site and to the mechanism and timing of injury.

Tips and tricks for DIEP flap breast reconstruction in patients with previous abdominal scar

The aim of this study was to analyze outcomes of patients who had prior abdominal operations and underwent DIEP flap breast reconstruction and to describe technical strategies to insure well‐vascularized flap‐harvest minimizing abdominal donor‐site complications. All patients who underwent DIEP flap breast reconstruction between 2004 and 2014 were reviewed and divided into a control group (CG) and a scar group (SG). Patient demographics, operative details, flap and donor‐site complications were analyzed and compared. For all of the scars, DIEP flap design was not modified, but a standardized approach was developed according to the type and location of the scar, available vascular pedicle, perforator locations, and the required flap tissue for breast reconstruction. Two hundred and eighty patients underwent 292 flaps in CG and 107 underwent 111 flaps in SG. Pfannenstiel, McBurney, laparoscopic, midline and subcostal were the most common previous incisions. There were no significant differences between groups regarding demographics, flap and mastectomy weight, active smoking, or radiation status (P > 0.05). No significant differences were observed in DIEP flap loss (P = 0.909), partial flap loss (P=0.799), or fat necrosis (P=0.871) and in the rate of abdominal donor‐site complications between groups (P > 0.05). SG had a significantly higher mean operative time than CG (P=0.034). Medial raw was a negative risk‐factor for flap complications, while BMI (>25.1 kg/m2) and smoking‐history were significant predictors for donor‐site complications. With careful preoperative planning and appropriate technical strategies, successfully DIEP flap breast reconstruction can be performed without increased flap and donor‐site complications in patients with preexisting abdominal scars.

One-stage DIEP flap breast reconstruction: Algorithm for immediate contralateral symmetrization

The aim of this study was to investigate clinical and aesthetic results of simultaneous contralateral balancing procedures in unilateral DIEP flap reconstructions by means of a symmetrization algorithm. Between 2004 and 2013, 335 patients underwent DIEP flap breast reconstruction with 48 patients (mean age 51.8 years, range 32–69 years) undergoing contralateral procedure. Patients were divided in Group‐A including 31 cases who underwent one‐stage procedure and Group‐B including 17 cases who underwent staged procedure. A symmetrization algorithm was proposed to plan immediate breast reduction/mastopexy. The groups were homogeneous regarding patients age, BMI, mastectomy and flap weight (P > 0.05). All flaps survived. No complications were observed to the mastectomy skin flaps and to the reduction mammaplasty/mastopexy procedures in both groups. The mean operation time was 5 h in Group‐A while 5 h and 37 min in Group‐B (P = 0.0682). Contralateral procedures included 23 breast reductions and 8 mastopexies in Group‐A, while 10 breast reductions and 7 mastopexies were performed in Group‐B. Two and 6 patients required revision of the balancing procedure in Group‐A and Group‐B, respectively. The follow‐up time was 47.3 months (range 14–120 months) in Group‐A and 91.3 months (range 41–110 months) in Group‐B. Volume, upper/lower pole shape, projection, breast mound placement, IMF, symmetry, overall appearance, and general satisfaction sub‐items obtained high‐score evaluation without significant difference between the two groups (P > 0.05). One‐stage DIEP flap reconstruction by means of the symmetrization algorithm resulted in comparable aesthetic outcomes and patient satisfaction to a staged procedure.

Compression of the digital nerves by a giant periosteal chondroma

Abstract We describe a left-handed man who had a giant periosteal chondroma of the proximal phalanx of the left third finger with compression of the digital neurovascular structures, and the flexor and extensor tendons. Cutaneous pressure thresholds of the digital nerves were tested, showing complete sensory recovery 24 months postoperatively.
