目的：应用高分辨率的彩色多普勒血流成像（ CDFI）对胫前动脉穿支的分布规律及血流动力学参数进行研究。方法应用CDFI对40侧胫前动脉穿支血管的数目、起始内径、走行、分布进行检测。并对穿支穿深筋膜处进行体表标记。应用脉冲多普勒（ PW）测量穿支起始处及穿深筋膜处收缩期峰值流速（ PSV），建立胫前动脉穿支血流动力学正常对照，并按侧别分组进行统计学分析。结果胫前动脉共40侧，检出穿动脉总数236支，每侧4～8支不等，平均5．9支。穿支沿3个肌间隙分布，集中在小腿中上段，胫前动脉穿支穿深筋膜位置大多集中在距离小腿外踝上15～27 cm（55．5％）。穿支动脉起始处及穿深筋膜处PSV左右侧组间差异无统计学意义（ P＞0．05）。结论彩色多普勒超声可直观地显示穿支的走行分布、有无变异或缺如，能在体表准确定位，并提供血流动力学定量指标评价血管质量，为皮瓣的设计提供可靠的依据。
目的：應用高分辨率的綵色多普勒血流成像（ CDFI）對脛前動脈穿支的分佈規律及血流動力學參數進行研究。方法應用CDFI對40側脛前動脈穿支血管的數目、起始內徑、走行、分佈進行檢測。併對穿支穿深觔膜處進行體錶標記。應用脈遲多普勒（ PW）測量穿支起始處及穿深觔膜處收縮期峰值流速（ PSV），建立脛前動脈穿支血流動力學正常對照，併按側彆分組進行統計學分析。結果脛前動脈共40側，檢齣穿動脈總數236支，每側4～8支不等，平均5．9支。穿支沿3箇肌間隙分佈，集中在小腿中上段，脛前動脈穿支穿深觔膜位置大多集中在距離小腿外踝上15～27 cm（55．5％）。穿支動脈起始處及穿深觔膜處PSV左右側組間差異無統計學意義（ P＞0．05）。結論綵色多普勒超聲可直觀地顯示穿支的走行分佈、有無變異或缺如，能在體錶準確定位，併提供血流動力學定量指標評價血管質量，為皮瓣的設計提供可靠的依據。

Objective To study the distribution rules and its flowing dynamics of perforator vessel of tibial anterior arteries with color Doppler imaging.Methods The quantity, the vascular initial diameter, distribution, the quality of the blood vessel and its flowing dynamics of 40 tibial anterior arteries were measured by CDFI.Marked at surface of the perforator perforating deep fascia.Peak systolic velocity ( PSV) from perforator starting to the deep fascia was measured by Pulse Doppler ( PW) .Establish normal control of the anterior tibial artery perforator blood flow dynamics and adopted statistical analysis by the side of the grouped.Results In altogeth-er, 40 legs studied, 236 cutaneous branches were found.Four to eight branches were found on one specimen and the average number of cutaneous perforators was 5.9.Septocutaneous perforators of the anterior tibial artery followed a reproducible pattern ( septa I, II andⅢ).In the distal segment, we found relatively few perforators.The perforating points of cutaneous branches mostly (55.5%case) ap-peared within 15-27 cm length above the lateral maleollus of fibula.There were no significant differences in the peak systolic velocity between left and right cutaneous perforators.Conclusion The color Doppler ultrasonography with high resolution could show the distri-bution and location clearly, assess the quality of the blood flow of perforators artery, and provide scientific basis for planning skin flap.
