摘要
目的寻找术前胰岛素瘤准确定位诊断的新方法。方法对５例胰岛素瘤患者术前应用动脉钙剂刺激静脉取血测定胰岛素的方法定位胰岛素瘤。经各供胰腺动脉分别注射葡萄糖酸钙，在注射前及注射后３０、６０、９０、１２０、１８０秒分别取２ｍｌ肝静脉血测定胰岛素。动脉刺激后血胰岛素水平的峰值超过基础值的２倍以上，则确定肿瘤位于该动脉供应的胰腺区域。结果５例胰岛素瘤术前应用该方法确定的位置与术中所见完全符合。结论动脉钙剂刺激静脉采血定位胰岛素瘤的方法准确可靠．安全可行。
Objective To establish a method for bocative diagnoses of insulinoma, Method Five patients with insulinoma were given locative diagnoses by using ASVS methods which mean injecting calcium stimulatant into pancreatic supplying arteries and then taking blood specimens from henatic vein to gauge the insulin levels. Six samples, each 2 ml, were taken before and 30, 60, 90, 120, 180 seconds after the injection.Results If the peak of blood insulin level was twice or higher than the basic level, the tumor was located in the domain. These results were confirmed operatively in all the five cases.Conclusion ASVS is an accurate technique to localize insulinoma.
