查询词典 main artery

The reasons for these complications: The main arteries as a result of high blood pressure resulted in a series of changes, especially the long-term systemic small artery spasm, may cause the vessel wall occurred in dystrophic changes in subintimal deposition of protein substances, fibrous tissue increased , in the muscle membrane hypertrophy, reduced arterial elasticity, resulting in luminal narrowing.

产生这些并发症的原因：主要是由于高血压使动脉产生了一系列变化，尤其是全身小动脉的长期痉挛，可能使血管壁发生营养不良性变化，内膜下蛋白性物质沉积，纤维组织增多，中膜肌层肥厚，动脉弹性减低，以致管腔变窄。

The main influential factors on surgical results were whether presence of encasement of the basilar artery and its branches and of the arachnoidal cleavage plane between the tumor and the brain stem.

PDA was often combined with all kinds of intracardial malformation ,preoperational diagnosis and interoperative exploration are extremely helpful for diagnosis . A strict control of indication and the improvement of CPB technique are significant to lower the death rate and postoperative complication . Suturing PDA through incision in pulmonary artery under CPB is the main treatment for PDA, using Foley catheter to block arterial canal flow helps to fully expose the operating field 、shorten CPB duration and lower the complications of lungs and brain .

各种心内畸形经常合并PDA，术前诊断及术中探查，意义重大；严格掌握手术指征和提高CPB技术，对降低手术死亡率及术后并发症具有重要意义；经肺动脉切口缝闭PDA是CPB下处理PDA的主要方法，术中应用 Foley导尿管阻断动脉导管血流，有利于术野显露、缩短CPB时间，可降低肺部、脑部并发症。

Finding effective drugs to treat PAH is a problem needed to be resolved. The main purposes of this study therefore were:① To assess the significance of radionuclide ventriculography in the diagnosis of early cor pulmonale and cor pulmonale with right heart failure.② To assess the rule of hemodynamic changes in patients with cor pulmonale especially in those patients who had been in decompensatory phase.③ TO assess the correlation between mean pulmonary artery pressure and right ventricular ejection fraction in order to establish a equation for diagnosing PAH noninvasively.④ To assess the effects of nifedipine , captopril and combining nifedipine with captopril on the treatment of PAH.

本文对慢性肺心病、PAH的无创诊断和有效治疗两方面进行研究，其目的在于：①了解放射性核素检查对早期肺心病和肺心病合并右心衰竭诊断的意义；②了解肺心病病人尤其是失代偿期肺心病病人血流动力学的改变规律，了解平均肺动脉压与右室射血分数等的相关性，探索建立一个无创诊断PAH的回归方程，祈能提供今后临床使用；③观察硝苯吡啶、卡托普利和两药联用对PAP等血流动力学参数的影响。
