Skull films of 5,570 patients older than 40 years of age admitted to the neurological (4,308), ophthalmologic (1,151), and otorhinolaryngologic clinics (111) of the University of Milan over a period of 20 years were reviewed for carotid siphon calcification. The 485 positive findings were divided into intimal and medial calcifications on the basis of morphological criteria. Signs of cerebrovascular disease in the territory of the internal carotid artery were seen in 35.1% of the intimal group and 37.2% of the medial group. These findings suggest that the two types of calcification do not have different prognostic values as theorized previously.
对米兰大学神经科（4308例）、眼科（1151例）和耳鼻喉科诊所（111例）20年间收治的5570例40岁以上患者的颅骨片进行了颈动脉虹吸部钙化情况的检查。根据形态学标准，将485例阳性结果分为内膜钙化和中膜钙化。在内膜钙化组中，35.1%的患者出现颈内动脉供血区域的脑血管病体征；在中膜钙化组中，这一比例为37.2%。这些发现表明，这两种类型的钙化并不像之前理论推测的那样具有不同的预后价值。
