A Comparative Study Between Deep Inferior Epigastric Artery Perforator and Thoracoacromial Venous Supercharged Deep Inferior Epigastric Artery Perforator Flaps.

BACKGROUND: Nowadays, microvascular breast reconstruction with abdominal perforator flap is a popular and widespread technique. However, venous congestion is a recurrent problem in deep inferior epigastric artery perforator (DIEP) flap survival. We present a venous supercharging technique using the thoracoacromial vein in DIEP free flap for breast reconstruction. METHODS: A prospective randomized study was conducted in 52 patients undergoing a free DIEP flap breast reconstruction. Classical DIEP flap using 1 venous anastomosis (DIEP group) was compared with thoracoacromial venous supercharged DIEP flap using the ipsilateral superficial epigastric vein as a supercharging vein (DIEP-TAsc group). The endpoint was to assess the equivalence or the superiority of each technique. Statistical analysis was made with the t test and the χ test. RESULTS: Venous congestion occurred in 16 (55.1%) patients in the DIEP group, and 3 (13%) patients in the DIEP-TAsc group (P = 0.001). The venous congestion rate was 36.5%. Fat necrosis was experienced by 14 (48.2%) patients in the DIEP group, and 4 (17.4%) patients in the DIEP-TAsc group (P = 0.020). The fat necrosis rate was 34.6%. Partial flap necrosis occurred in 13 (44.8%) patients in the DIEP group, and 2 (8.7%) patients in the DIEP-TAsc group (P = 0.004). The partial flap necrosis rate was 28.8%. Total flap necrosis occurred in 5 (17.2%) patients in the DIEP group, but no (0%) patient in the DIEP-TAsc group (P = 0.036). The total flap necrosis rate was 9.6%. The mean operative time was 405 minutes (range, 355-460) in the DIEP group, and 510 minutes (range, 405-590) in the DIEP-TAsc group (P < 0.001). CONCLUSIONS: Thoracoacromial venous supercharging using the ipsilateral superficial inferior epigastric vein is a valuable method which considerably secures the DIEP free flap in breast reconstruction although it lengthens the operative procedure. EBM level: Level III.

Dermal flaps in breast reduction: prospective study in 100 breasts.

The most common complication of breast reduction with inverted T-scar technique is wound dehiscence at the junction of the vertical and horizontal sutures. In this study, a technique involving three triangular dermal flaps is presented with the results for healing in the junctional T zone. Fifty women were included in a comparative, single-center randomized double-blind prospective study to evaluate the efficiency of the three-triangular dermal-flap technique in healing in the junctional T zone. All patients were seen for follow-up at 7 days, 14 days, 21 days, 28 days, 35 days, 42 days, and 49 days after surgery to evaluate primary healing in the T zone. Average healing time was 19.7 days in the triangular-skin-flap series and 25.48 days in the control series, with a statistically significant difference (p < 0.01). One patient in the triangular-skin-flap series experienced dehiscence in the T zone (2%) versus eight patients (16%) in the control series. A statistically significant difference was noted (p = 0.012). This technique is based on the association of two principles. First, ischemia on the edges as well as skin necrosis is limited by suturing the two superior skin flaps rather than directly suturing the cutaneous angles. In addition, this technique brings an underlying dermal support. Second, the inferior flap width allows fixing two sutures laterally to limit the central tension. This easy technique does not lengthen total operative time and significantly improves healing time. It is applicable to all breast reductions with inverted T scars.

Use of botulinum toxin type A to improve treatment of facial wounds: a prospective randomised study.

BACKGROUND: The tension vectors acting on the wound edges are transmitted to immature collagen fibres synthesised during the normal healing phase. This accounts for scar widening as well as hypertrophic and hyperpigmented scars. The aim of our study was to evaluate whether early injections of botulinum toxin type A (BTA), which induces temporary muscular paralysis, decreases tension vectors on wound edges and enhances scarring of facial wounds. PATIENTS AND METHODS: Thirty patients with facial wounds were enrolled in this study and randomised into two groups with or without injection of BTA within 72 h postoperatively. BTA was injected into the facial muscles directly or indirectly involved in scar widening. Scars were assessed at a 1-year follow-up visit by patients using the Patient Scar Assessment Scale (PSAS) scale, by an independent evaluator using the Observer Scar Assessment Scale (OSAS) and the Vancouver Scar Scale (VSS), and by a board of six experienced medical specialists using the Visual Analogue Scale (VAS) with standardised photographs. RESULTS: At the 1-year visit, 24 patients were reviewed and six patients were lost to follow-up. No statistically significant differences were found between the two groups for the PSAS, OSAS and VSS scores. However, the median VAS rated by the six evaluators was 8.25 for the botulinum toxin-treated group compared with 6.35 for the control group. This result was statistically different, demonstrating improved scarring with BTA. CONCLUSIONS: Thanks to chemoimmobilisation, injections of BTA appear to improve cosmesis of facial wounds. Accordingly, they would be beneficial for use in young patients for wounds without tissue loss, lying perpendicular to the reduced tension lines of the skin of the face.

Reconstruction of anterior scalp defect with V-Y advancement flap pedicled on the temporal fascia superficialis.

Reconstruction of scalp defect can call upon several surgical techniques. Direct joining is used whenever possible, but because of the low laxity of the scalp, other approaches are often required. Several types of autoclosing flaps of the scalp have been described in the literature. In this article, we report the advantages of the island flap pedicled on the superficial temporal fascia, as described by Onishi (2005) in a case report for the reconstruction of an anterior scalp defect.

Retrospective French nationwide survey of childhood aggressive vascular anomalies of bone, 1988-2009.

OBJECTIVE: To document the epidemiological, clinical, histological and radiological characteristics of aggressive vascular abnormalities of bone in children. STUDY DESIGN: Correspondents of the French Society of Childhood Malignancies were asked to notify all cases of aggressive vascular abnormalities of bone diagnosed between January 1988 and September 2009. RESULTS: 21 cases were identified; 62% of the patients were boys. No familial cases were observed, and the disease appeared to be sporadic. Mean age at diagnosis was 8.0 years [0.8-16.9 years]. Median follow-up was 3 years [0.3-17 years]. The main presenting signs were bone fracture (n = 4) and respiratory distress (n = 7), but more indolent onset was observed in 8 cases. Lung involvement, with lymphangiectasies and pleural effusion, was the most frequent form of extraosseous involvement (10/21). Bisphosphonates, alpha interferon and radiotherapy were used as potentially curative treatments. High-dose radiotherapy appeared to be effective on pleural effusion but caused major late sequelae, whereas antiangiogenic drugs like alpha interferon and zoledrenate have had a limited impact on the course of pulmonary complications. The impact of bisphosphonates and alpha interferon on bone lesions was also difficult to assess, owing to insufficient follow-up in most cases, but it was occasionally positive. Six deaths were observed and the overall 10-year mortality rate was about 30%. The prognosis depended mainly on pulmonary and spinal complications. CONCLUSION: Aggressive vascular abnormalities of bone are extremely rare in childhood but are lifethreatening. The impact of anti-angiogenic drugs on pulmonary complications seems to be limited, but they may improve bone lesions.
