颈动脉

The therapeutic efficacy in posterior extension sitting position occupying 11-20° was better in upper hind neck; the therapeutic efficacy in anteversion sitting position occupying 11-20° was better in inferior neck; the therapeutic efficacy in anteversion sitting position occupying 1-10° was better in neutral position sitting position.

即上颈段椎动脉型颈椎病患者坐位后伸11°~20°牵引疗效较好，下颈段椎动脉型颈椎病患者坐位前屈11°~20°牵引疗效较好，混合型椎动脉型颈椎病患者坐位前屈1°~10°疗效较好。

It was suggested that structure changes such as incurvation and stenosis of the vertebral artery caused by spondylopathy were reasons of cervical vertigo.

结果表明，颈椎病所致的椎动脉弯曲、狭窄等结构改变是引起颈性眩晕的主要原因，而转颈时椎动脉的上述改变明显加重。

The donor brachiocephalic trunk and pulmonary artery were anastomosed to the recipient right common carotid artery and right external jugular vein respectively.

将供心的无名动脉和肺动脉分别与受体的右颈总动脉和右颈外静脉行套管法连接。

METHODS Neonatal HIBD models were made according Rice method, new-born rabbits wereanesthetized by aether inspiration, and their right common carotid arteries were ligated.Experimental animals were put into the hypoxic champer (8%FIO2) for two and anhalf hours. Control groups included five ligated animal which didnt undergo hypoxicmanagement.

实验方法按照Rice法制备新生兔缺氧缺血性脑损伤模型，即用乙醚吸入麻醉动物，5％盐酸利多卡因局部浸润麻醉，颈部正中切口，剥离右侧颈总动脉和迷走神经，用2号缝线将剥离出的右侧颈总动脉作永久结扎。

Methods Eighty Class Ⅱ isogeneic F344 rats, weighing 250-350 g, were randomly divided into 2 groups(n=40). The control group adopted the Strome model. The allograft used for the experimental group preserved ascending pharyngeal artery, which formed a complex allograft together with tongue base, larynx and pharyngolarynx. End-to-end anastomosis was performed between both allograft common carotid arteries and anterior neck veins. The patency rate and survival rate of the allograft of the 2 groups were compared.

80只Ⅱ级近交系F344大白鼠，体质量250~350 g，随机分为2组，每组40只，共20对对照组采用Strome喉移植模型，实验组在切取供体喉时保留咽升动脉，将舌根、喉、喉咽作为复合移植体，供体大鼠双侧颈蓉动脉分别与受体大鼠颈总动脉、颈前静脉进行端端吻合重建移植喉血液循环，比较两组术后动静脉通畅率及移植喉存活率。

Results In the 12 cases with 17 nonbronchial systemic arteries （4 were intercostal, 3 internal mammary, 3 thyrocervical trunk, 3 inferior phrenic, 1 left gastric, 2 originated from the inferior aortic arch, and 1 originated from anterior abdominal aortic wall）.

结果12例共17支肺外体循环动脉中，包括4支肋间动脉、3支内乳动脉、3支甲状颈干、3支膈动脉、1支胃左动脉、2支动脉源于主动脉弓下缘和1支动脉源于腹主动脉前壁。

After the ligation of both CCAs, the decrease of cerebal blood flow is compensated by the formation of collateral circulation and the dilation of basilar artery, and CCA' ligation is a feasible technique in establishing symptomatic cerebral vasospastic model.

颈总动脉结扎后，兔脑可能靠侧支循环增加和基底动脉增粗来代偿脑血流的下降；在症状性脑血管痉挛模型的制作中，颈总动脉结扎是一项可行的技术。

Then,the left external carotid artery of 40 adult New Zealand White rabbits were ligated,which reduced the pulsatile shear stress of left common carotid significantly (for example, mean=21.16 ± 7.17 vs 3.13±2.28 dynes/cm2, p=2.176E-21)and did not change the pulsatile shear stress of right common carotid significantly.

结果左颈外动脉结扎后即刻兔的左颈总动脉形成脉动低切应力以τ_(mean为例，从21.16±7.17dynes/cm~2降至3.13±2.28dynes/cm~2，p=2.176E-21，并一直持续至结扎12周后；而右颈总动脉脉动切应力始终无显著变化。

Methods To observe the common carotid artery and its bifurcation, the internal carotid artery, external carotid artery intima-media thickness, plaque echo and hemodynamic changes.

方法观察颈总动脉及其分叉处、颈内动脉、颈外动脉内中膜厚度、斑块回声及血流动力学改变。

This software can show the vessel stenosis, calcification and the relation with surrounding sclerotin clearly. It shows the stenosis section exactly and calculates the degree of stenosis automatically. Conclusion The 16-row CT angiography is no-trauma and can be the first choice in diagnosis of carotid artery stenosis.

结果 17例患者CTA显示颈总动脉、颈外动脉、颈内动脉显示率为100%；颈内动脉狭窄18支，其中轻度狭窄10支，中度狭窄4支，重度狭窄3支，闭塞1支；其软件能清晰显示血管狭窄、钙化和周围骨质的关系，准确显示狭窄段，计算狭窄程度。
