摘要
背景:胸背动脉穿支(TDAP)皮瓣是一种多用途的带蒂自由皮瓣,供区发病率低,皮瓣相对较薄。患者的身体特征可能会影响穿支特征的个体差异,因此,有助于估计TDAP皮瓣的安全性。方法:应用动态红外热像仪和彩色双超对25例患者双侧背阔肌TDAP直径、收缩峰值速度(PSV)、舒张末期速度、阻力指数、背阔肌及皮下组织厚度进行测定。研究了旋手性对穿孔特性对称性的影响。结果:穿支特性不受性别或体重指数的影响。背阔肌平均厚度与穿支直径(Pearson’s r = 0.25, p = 0.0048, n = 124)和PSV (r = 0.29, p = 0.0012, n = 124)呈正相关。皮下组织厚度与PSV呈负相关(r = -0.31, p = 0.0003, n = 124)。优势侧和非优势侧穿支直径和PSV比较无统计学差异。结论:研究结果表明,胸背侧动脉皮瓣的灌注增强是由于背阔肌增厚、皮下组织变薄和tdap数量减少。
Thoracodorsal Artery Perforator Diameter and Flow Velocity Correlate with Muscle Thickness.
Background: The thoracodorsal artery perforator (TDAP) flap is a versatile pedicled and free flap with low donor site morbidity and a relatively thin skin paddle. Physical patient characteristics may influence interindividual differences in perforator characteristics and, therefore, help to estimate the safety of the TDAP flap.
Methods: Dynamic infrared thermography and color duplex ultrasound were applied to assess the TDAP diameter, peak systolic velocity (PSV), end-diastolic velocity, resistance index, and thickness of the latissimus dorsi muscle and the subcutaneous tissue bilaterally in 25 subjects. The effect of handedness on the symmetry of perforator characteristics was investigated.
Results: Perforator properties were not significantly altered by sex or body mass index. The mean latissimus dorsi muscle thickness correlated positively with both the perforator diameter (Pearson's r = 0.25, p = 0.0048, n = 124) and the PSV (r = 0.29, p = 0.0012, n = 124). In contrast, a negative correlation was observed between subcutaneous tissue thickness and PSV (r = -0.31, p = 0.0003, n = 124). A comparison of the perforator diameter and the PSV in the dominant and nondominant sides showed no statistically significant difference.
Conclusion: The findings of the study indicate that perfusion of the thoracodorsal artery flap is enhanced by the presence of a thicker latissimus dorsi muscle, a thinner subcutaneous tissue, and a reduced quantity of TDAPs.
期刊介绍:
The Journal of Reconstructive Microsurgery is a peer-reviewed, indexed journal that provides an international forum for the publication of articles focusing on reconstructive microsurgery and complex reconstructive surgery. The journal was originally established in 1984 for the microsurgical community to publish and share academic papers.
The Journal of Reconstructive Microsurgery provides the latest in original research spanning basic laboratory, translational, and clinical investigations. Review papers cover current topics in complex reconstruction and microsurgery. In addition, special sections discuss new technologies, innovations, materials, and significant problem cases.
The journal welcomes controversial topics, editorial comments, book reviews, and letters to the Editor, in order to complete the balanced spectrum of information available in the Journal of Reconstructive Microsurgery. All articles undergo stringent peer review by international experts in the specialty.
