摘要
目的：观察椎动脉硬化形态学变化特点,以及椎动脉形态变化与临床表现的关系.方法：对415例患者行全脑数字减影血管造影检查.结合临床表现对椎动脉的形态变化（迂曲延长和狭窄）进行分析.结果：415例中,造影显示椎动脉迂曲延长和狭窄311例（74.9%）,其中迂曲延长者176例（56.6%）、动脉狭窄者135例（43.4%）;在动脉迂曲延长中,＂C＂型、＂S＂型和＂O＂型迂曲分别为54.5%（96/176）、32.4%（57/176）和13.1%（23/176）.＂C＂型迂曲表现为头昏者占54.2%（52/96）,高于＂S＂型的28.1%（16/57）和＂O＂型的17.4%（4/23）,组间比较差异有统计学意义（P＜0.05）.而脑梗塞发生率＂C＂型与另两型比较,差异无统计学意义（P＞0.05）.结论：椎动脉硬化形态学变化越明显,临床表现越严重.椎动脉硬化形态变化的原因有待于进一步研究.
Objective：To observe the morphologic changing characteristics and clinical manifestations of vertebral artery stenosis. Methods：415 patients underwent digital subtraction angiography（DSA） , the mor- phologic changes of vertebral artery combined with the clinical manifestations were analyzed（ circuity extension and stenosis ）. Results：311 cases（74.9% ） of DSA with circuity extension or stenosis in 415cases, of which circuity extension in 176 cases （56.6%）, stenosis in 135 cases （43.4%） . There were 96 cases （54.5%） with＂C＂ type and 57 cases （32.4%） with ＂S＂ type and 23 cases （13.1%） with ＂O＂ type. There were 54.2% （52/96） ,28.1% （16/57） and 17.4% （4/23） with dizziness in ＂ C＂ ,＂ S＂ and ＂ O＂ typed tortuosity. There was a significant difference between the ＂ C＂ and ＂S＂ typed tortuosity（P 〈 0.01 ） and between the ＂ C＂ and ＂O＂ typed tortuosity （P 〈 0.05 ）. The ＂S＂ type and ＂0＂ type induced cerebral infarction were not significant difference than the ＂ C＂ type（ P 〉 0.05）. Conclusions：The morphologic changing characteristics of vertebral artery obviously affect its clinical manifestations and the causes need further study.
