In order to determine the clinical significance and hemodynamic relevance of carotid siphon calcification 241 patients were investigated by doppler sonography and skull x-ray. Comparing 139 patients with and 60 patients without siphon calcification, we examined the predictive value of carotid calcification regarding obstructive vessel disease as indicated by doppler sonography. Both groups were compared with 42 patients who all had doppler sonographic signs of severe carotid stenosis. No significant difference was found regarding the incidence of stenosis between the groups with and without siphon calcification (13% vs. 15%). Interpreting siphon calcification as a general sign of atherosclerosis seems therefore not justified. An over proportionally high rate (61.9%) of siphon calcification can only be expected by selected patients with severe obstructive vessels disease. Etiological factors are discussed and differential diagnosis of siphon calcification is demonstrated by cases.
为了确定颈动脉虹吸部钙化的临床意义和血流动力学相关性，对241例患者进行了多普勒超声检查和颅骨X线检查。比较了139例有虹吸部钙化的患者和60例无虹吸部钙化的患者，我们研究了多普勒超声所示颈动脉钙化对阻塞性血管疾病的预测价值。将这两组与42例均有严重颈动脉狭窄多普勒超声征象的患者进行比较。有和无虹吸部钙化的两组之间在狭窄发生率方面未发现显著差异（分别为13%和15%）。因此，将虹吸部钙化解释为动脉粥样硬化的一般征象似乎没有依据。只有在患有严重阻塞性血管疾病的特定患者中，才可能出现比例过高的虹吸部钙化率（61.9%）。文中讨论了病因，并通过病例展示了虹吸部钙化的鉴别诊断。
