许多甲低患者有前庭功能障碍,但无临床症状。我们对16例患者做眼震图和耳蜗电图检查,发现有33.1%半规管异常,31.3%迷路水肿(—SP升高,—SP/A P>0.4),心包积液的3例中2例有迷路水肿,但两者的发生均与甲状腺功能水平不相关。迷路水肿组中心排血量、左室重量、舒张末左室容积,平均射血速度、左室应力、收缩中期左室内膜应力均显著低于无迷路水肿组。作者认为这种现象与免疫学改变有关。
Many patients with hypothyroidism have vestibular dysfunction, but no clinical symptoms. We performed nystagmograms and electrocochleograms on 16 patients and found 33.1% of semicircular canal abnormalities, 31.3% of labyrinthine edema (-SP elevation, -SP / AP> 0.4), and 2 of 3 patients with pericardial effusion Lost edema, but the incidence of both are not related to thyroid function. The volume of left ventricular ejection, left ventricular mass, left ventricular end-diastolic volume, mean ejection velocity, left ventricular stress, and left ventricular end-diastolic stress were significantly lower in patients with labyrinthine edema than those without labyrinthine edema. The authors believe that this phenomenon is related to immunological changes.
