Results The measurement showed the vertebral artery of the patients with bends more severely, the second stricture and atherosclerosis plaque leadings ...

颈部椎动脉形态与结构的改变是引起血流动力学改变的基础。椎动脉内血流速度减慢导致了椎基底动脉供血不足

Result The skewed parabolic profile is observed in CCA under 1:60 curvature and physiological average Reynolds number. As curvature and Reynolds number increase, the middle of horizontal profile appears sunken and the vertical profile is M-shaped. There are different profile shapes in different localities along the curved pipe.

结果 当颈总动脉的曲率等于1：60 时，在人生理平均流动雷诺数条件下，颈总动脉的速度剖面可用偏斜的抛物面来近似；当颈总动脉曲率增大或流动雷诺数增大时，弯曲平面上的速度剖面中部出现下凹趋势，垂直方向上出现M型速度剖面；沿管轴不同位置上的速度剖面形状不同。

Methods The changes of contents of AGEs in plasma and the abdominal aorta and changes of VSMC of the abdominal aorta were investigated with methods of fluorospectrophotometry, immunohistochemistry, computer image analysis and transmission electron microscopy on streptozotocin-induced diabetic rats. Results From the fourth week, in diabetic rats, the contents of AGEs in plasma and the abdominal aorta increased, the relative area of α-SM-actin in the abdominal aorta decreased, the density of nucleus of VSMC increased, and mitochondria and rough endoplasmic reticules in VSMC increased.

后者在早期主要是血管平滑肌细胞(vascular smooth muscle cell， VSMC)和胶原纤维增多，弹性纤维减少，动脉增厚等，引起动脉的顺应性降低，舒张功能减弱［1～3］；晚期主要表现为动脉粥样硬化和动脉硬化，其中以VSMC的增生和迁移较为突出，其表型也由收缩型转化为合成型［4，5］。

ACA = anterior communicating artery; BA = basilar artery; LACA = left anterior cerebral artery; LCCA = left common carotid artery; LECA = left external carotid artery; LICA = left internal carotid artery; LMCA = left middle cerebral artery; LPCA = left posterior cerebral artery; LSA = left subclaian artery; LA = left ertebral artery; RACA = right anterior cerebral artery; RCCA = right common carotid artery; RECA = right external carotid artery; RICA = right internal carotid artery; RMCA = right middle cerebral artery; RPCA = right posterior cerebral artery; RSA = right subclaian artery; RA = right ertebral artery.

ObjectiveThe sinus node artery is the only blood supply for the sinus node, and cardiac arrhythmia is common when the artery is involved in coronary artery diseases or in heart surgeries. Thus its important for selective coronary angiographies and cardiac surgeries to make clear the form and course of the sinus node artery.

目的 窦房结动脉(sinus node artery，SNA)是窦房结的唯一血供来源，当冠心病或心脏手术累及该动脉时都可导致窦房结缺血而发生各种心律失常，所以对窦房结动脉的形态及走行的认识在选择性冠脉造影和心脏外科手术等方面都具有重要意义。

The periodical changes is propagated along the arterial tree, arrive at radialis artery, and then can be detected.

心脏周期性搏动，将血液射入动脉管道，动脉管内的血压，血流量以及动脉管壁都随之发生一系列周期性的变化，这些变化传播到桡动脉处，可被诊知。

Results Constrictions were found in subclavian arteries of 9 patients,occlusion was found in the left brachial artery of one patient and aneurysm was found in the right axillary artery of one patient.8 cases were proved by DSA.

结果： 13例上肢CTA中，有9例锁骨下动脉狭窄，1例左侧肱动脉完全闭塞，1例右侧腋动脉动脉瘤，其中8例经DSA证实。

It included the oculomotor nerve, the total length of the posterior communicating artery,the posterior cerebral artery segment P1,P2, and the upper basilar artery.

包括动眼神经起始部至入海绵窦后壁，后交通动脉全长，大脑后动脉的P1P2段，基底动脉的上部和分叉部。

The hyperform balloon catheter was introduced into the right common carotid artery through a small window in the right femoral artery. road map of the right cca was drawn in the control group.

所有动物采用经右侧股动脉入路置入hyperform球囊，实验组行右颈总动脉定比扩张，对照组行单纯右颈动脉路图显示，术后以普通饮食喂养。
