研究三叉神经痛患者外周血管及微循环改变 ,探讨其发病原因及机理。方法　选择 30例患者及 2 8名同年龄组正常人 ,测定基础血压、血脂及全血粘度 ,将结果进行对比研究。结果　与正常人对比 ,患者舒张压、胆固醇、甘油三脂及全血粘度显著增高 (P<0 .0 5或 P<0 .0 1)。结论　三叉神经痛与血管硬化、微循环障碍及相应的神经结构改变有关 To study the changes of peripheral blood vessels and microcirculation in patients with trigeminal neuralgia and to explore its etiology and mechanism. Methods Thirty patients and 28 normal subjects of the same age were selected. The blood pressure, blood lipid and whole blood viscosity were measured. The results were compared. Results Compared with normal people, the diastolic blood pressure, cholesterol, triglyceride and whole blood viscosity were significantly increased (P <0.05 or P <0.01). Conclusion Trigeminal neuralgia is associated with vascular sclerosis, microcirculation disorder and corresponding neuro-structural changes
