In a previous work, the writers have described the influence of vasomotoricity on the shape of the ultrasonic velocimetric curves (Doppler). A vasodilatation induced by an anaesthesia of the sympathetic chain or by a general anaesthesia by penthotal produces a raising of the whole curve above the basic line. The writers have studied in the present work the shape of the velocimetric curves after a lumbar sympathectomy and have compared them with the variations of the cutaneous thermometry and with the clinical results. A correlation has been found in 86.3% of the 124 studied limbs. The study shows that the raising of the curve due to the phenomenon of vasodilatation appears only at the extremity of the limb. The profile of the curve remains unchanged at the root. A velocimetric curve above the basic line may occur apart from any vasomotoric modification. In this case it is the sign of an up-stream obliteration combined with a drop of the index of perfusion (less than the unit).
在之前的一项研究中，作者们描述了血管舒缩性对超声测速曲线（多普勒）形状的影响。由交感神经链麻醉或戊巴比妥全身麻醉引起的血管舒张会使整个曲线升高至基线之上。在本研究中，作者们研究了腰交感神经切除术后测速曲线的形状，并将其与皮肤温度测量的变化以及临床结果进行了比较。在所研究的124条肢体中，86.3%发现存在相关性。研究表明，由于血管舒张现象导致的曲线升高仅出现在肢体末端。曲线在根部的形态保持不变。高于基线的测速曲线可能在没有任何血管舒缩改变的情况下出现。在这种情况下，它是上游闭塞并伴有灌注指数下降（小于单位值）的标志。
