The indications, results and evaluation methods of lumbar sympathectomy are very controversial. The authors present their experience and results with phenol lumbar sympathectomy (PLS). PLS (Reid's technique) was carried out in 25 patients with severe peripheral arterial disease. Sympathetic tone abolition was achieved in 72% of the patients, with a beneficial clinical effect in 60%. In this group, the following measurements were made, before sympathectomy, and 24 hours, one week and one month after it: Doppler ankle-pressure, ankle-arm pressure index and calf and foot arterial flow measured with an impedance plethysmograph (IPG), at rest and after controlled exercise. The IPG-measured arterial flow in the resting foot was the only parameter to show a significant increase following PLS (p less than 0.05). Although the IPG calf flow, ankle-pressure and ankle-arm index showed increases, these were not significant. Lumbar sympathectomy by phenol injection is as effective as by surgery. Its beneficial effect is believed to be due to an increase in the resting flow in the foot.
腰交感神经切除术的适应证、结果及评估方法极具争议性。作者介绍了他们采用酚妥拉明腰交感神经切除术（PLS）的经验和结果。对25例严重外周动脉疾病患者实施了PLS（里德技术）。72%的患者实现了交感神经张力消除，60%的患者有良好的临床效果。在该组患者中，于交感神经切除术前、术后24小时、1周及1个月进行了以下测量：多普勒踝压、踝臂压力指数以及使用阻抗体积描记仪（IPG）在静息状态和控制性运动后测量的小腿和足部动脉血流。IPG测量的静息足部动脉血流是PLS后唯一显示出显著增加的参数（p<0.05）。尽管IPG测量的小腿血流、踝压和踝臂指数有所增加，但并不显著。酚注射腰交感神经切除术与手术效果相同。其有益效果被认为是由于足部静息血流增加所致。
