Nuclear angiography was used in the assessment of the effects of lumbar sympathectomy in 16 patients. Computed nuclear angiographic study was performed before and after sympathectomy. 7 patients had a good clinical course and 9 had a poor prognosis. Visual observation and computed analysis gave almost equal information. Shortening of arrival time (ATdecrease) and increase in input rate ratio (IRratio) were the most suitable parameters in computed analysis. A good clinical course was probable if ATdecrease was greater than or equal to 5 s and IRratio greater than or equal to 1.3. Smaller values predicted poor prognosis. Preoperative Doppler ankle/arm systolic blood pressure index (API) greater than or equal to 0.50 predicted good and less than or equal to 0.50 poor clinical response. Postoperative API provided no additional information and was not able to measure the effects of sympathectomy. Radionuclide angiography was found to be a safe, noninvasive reliable method in the evaluation of peripheral circulation in the follow-up of sympathectomy.
核血管造影术用于评估16例患者腰交感神经切除术的效果。在交感神经切除术前后进行计算机核血管造影研究。7例患者临床病程良好，9例预后较差。视觉观察和计算机分析提供的信息几乎相同。到达时间缩短（AT降低）和输入率比值增加（IR比值）是计算机分析中最合适的参数。如果AT降低大于或等于5秒且IR比值大于或等于1.3，则临床病程可能良好。较小的值预示预后较差。术前多普勒踝/臂收缩压指数（API）大于或等于0.50预示临床反应良好，小于或等于0.50则预示较差。术后API未提供额外信息，无法测量交感神经切除术的效果。放射性核素血管造影术被发现是评估交感神经切除术后随访中外周循环的一种安全、无创的可靠方法。
