动脉充血

方法选择60例高血压病患者和55例健康者进行肱动脉充血实验，测定反应性充血后动脉内径变化率（FMD）。

Methods According to celermajer method of vascular ultrasound scans , flow mediated dilatation was observed in60 patients with hypertension and55 healthy people .

结果高血压病患者肱动脉充血后内径变化率显著低于健康者。

Results The FMD of patients with hypertension was significantly decreased compared with that of healthy people .

目的通过肱动脉充血实验介导的血流依赖性舒张功能，进行高血压病患者和健康者内皮功能的比较。

Objective The aim is to compare vascular endothelial function between patients with hypertension and healthy people by flow mediated dilatation ( FMD ) .

方法：采用高分辨率超声技术和肱动脉充血反应法，检测短暂性脑缺血发作患者治疗前后肱动脉内径变化率。

METHODS : High resolution ultrasound technique and brachial artery congestion method were used to test the internal diameter change rate of brachial artery in TIA patients before and after treatment .

结论：①在慢性肝炎及早期肝硬化阶段即可出现脾循环亢进，这一变化与脾脏动脉性充血有关；

Conclusion : ① Splenic hyperdynamic circulatory state might be already existed in chronic hepatitis and early cirrhosis due to active splenic congestion .

ASD患者长期左向右分流可导致右心容量负荷过重、肺动脉高压、充血性心力衰竭及房性心律失常。
