Abstract:
BACKGROUND:We describe a new dual neurorrhaphy method for a free abdominal-based flap and compare sensory recovery with this novel technique to that with conventional neurorrhaphy technique for breast reconstruction. METHODS:70 breast cancer patients underwent muscle sparing innervated transversal rectus abdominis myocutaneous flap (neuro ms-TRAM) breast reconstruction with either a novel dual neurorrhaphy technique (N = 41) or single (N = 29) neurorrhaphy only. Dual neurorrhaphy was performed on both sides and single neurorrhaphy on one side of the flap, using the end-to-end or end-to-side technique. Two years postoperatively, quantitative sensory testing (QST) was performed for tactile, and thermal sensory modalities, and other tests included sharp-blunt, vibration, and two-point discrimination. Sensory modalities were scored either zero (abnormal) or one point (normal) at each test site against normal reference values (five sites for most tests). The total sensory scores (TSC) were calculated on the basis of the sums of the individual test scores, and all data are presented as the median (interquartile range, IQR). RESULTS:The median of TSC in the breast reconstruction with the dual neurorrhaphy was higher (15.3, IQR 11.8-19.4), than that with the single neurorrhaphy (11.5, IQR 9.1-17.4) (P = 0.037). Regarding the different sensory modalities, the dual technique especially enhanced the tactile (P = 0.005) and cool detection (P = 0.021) recovery compared to the single neurorrhaphy. CONCLUSIONS:Dual neurorrhaphy improved the sensory recovery of the reconstructed breast, and may therefore be recommended for clinical practice. © 2014 Wiley Periodicals, Inc.

MICROSURGERY文献大全abstract:BACKGROUND:To obtain free flap success, microvascular anastomosis must be perfectly constructed. External compression, twisting (torsion) of the anastomosis site, tension on the anastomosis site, and kinking of the pedicle must be avoided. Few experimental studies report the patency rates of rat vessels after twisting ...
