摘要
目的 应用高分辨率彩色多普勒超声观察家族性高胆固醇血症(FH)患者腹部及外周动脉血管改变,以便为FH患者临床治疗提供有价值的依据。方法 采用彩色多普勒超声分别对5例FH家系中6名子女(先证者)及6名正常者进行血管超声检查,观察动脉内中膜厚度(IMT),管腔狭窄程度以及血液动力学改变。结果 FH组与对照组的左颈外动脉起始部后壁IMT、右颈总动脉近段后壁IMT与右颈总动脉中段前、后壁IMT以及左颈外动脉起始部、右颈总动脉近段与右颈总动脉中段的直径狭窄率差异均有统计学意义(P=0. 015);而FH组与对照组中椎动脉、锁骨下动脉、腹主动脉、肾动脉、髂动脉、腘动脉均未见明显动脉IMT增厚。结论 FH患者血脂水平不能准确地反映FH患者动脉粥样硬化的恶化程度,定期的超声检查有可能为FH患者个体化治疗提供有意义的依据。
Objective To explore changes of abdominal and peripheral arteries in familial hypercholesterolemia(FH) patients with definite etiopathogenisis by high-resolution color Doppler ultrasound;to identify the arteriosclerotic progression of FH patients and offer the valuable foundation for clinic treatment. Methods Observe the interior- media thickness(IMT), stenotic degree and hemodynamics change of arteries by ultrasonography in six children in five family constellations (index case) and six normal controls.Results There was significant difference between FH and control group in IMT of the posterior wall in left external carotid artery (origination), right common carotid artery (approaching piece) and IMT of the anterior and posterior wall right common carotid artery (intermediate piece) (P=0.015). Significant thickening of IMT was not observed in vertebral arteries, subclavicular arteries, abdominal aorta, renal arteries, iliac arteries and popliteal arteries both in FH and control group.ConclusionThe arteriosclerotic aggravation of FH patients could not be revealed by the level of the blood fat, but could be revealed correctly by ultrasonography. It is possible to provide significant foundation for individualized treatment of FH patients by regular non-invasive ultrasonography.
