摘　　要：目的 :应用 TCD探讨甲亢的脑血流动力学特点及其应用价值。方法 :按常规探测 5 0例青年甲亢患者颅内各动脉的血液动力学指标 ,与 30例健康正常组对照。 5 0例患者并分为血流速度显著增高 (A组 )、中度增高 (B组 )、轻度增高 (C组 )三组。结果 :所有患者血流速度均增高 ,收缩峰高尖 ,搏动指数正常 ,血管杂音占 70 % ,头痛占6 0 %。 A组 T3、T4值显著高于 B、C组 ,TSH值显著低于 B、C组 ;B组 T3、T4值显著高于 C组 ,TSH值显著低于 C组。A组其血管杂音、头痛比例明显高于其它两组。结论 :脑血流速度的增高程度可初步反映甲亢的严重程度 ,并与血管杂音及头痛的发生有关 ,TCD可用来评价甲亢的严重程度并可提高早期确诊率。Objective:To test the hemodynamic characteristics in patients with hyperthyroidism and find the clinical value of TCD.Methods:We examined and recorded the intracranial hemodynamic indexes of 50 cases with hyperthyroidism and 30 healthy controls by TCD.Fifty patients were divided into 3 groups based upon the increased velocities:the highest velocity group(group A),the moderate velocity group(group B)and the mild velocity group(group C).Results:The increase of velocities was found in all patient groups.The systolic velocity was high and sharp,but the pulsatility index was normal.Vascular bruits were found in 70% patients and headache were found in 60% patients.T 3 and T 4 of group A were significantly higher than those of group B and C,while TSH of group A was significantly lower than those of group B and C;T 3 and T 4 of group B were signficantly higher than group C,while TSH of group B was significantly lower than those of group C.Vascular bruits and headache were most often found in group A than those in the other 2 groups.Conclusions:The severeness of hyperthyroidism can be observed by the increased cerenbral blood velocities which would affect vascular bruits and headache.TCD can help us in judging the severity of hypertrhyoidism and effectiveness of therapy.It may be possible to raise the early diagnostic rate also.
