血管狭窄

Vessel foreshortening in angiographic images may cause errors in the assessment of lesions or the selection and placement of stents, and can be influenced by the viewing angles.

在造影图像中，由于透视投影成像导致的血管缩短会引起血管狭窄估计及支架选择和放置错误，而血管缩短与造影角度的选择有关。

BACKGROUND: Great saphenous vein is the most common vascular material in coronary artery bypass grafting, however, the graft neointimal hyperplasia and subsequent atherosclerosis result in angiostegnosis, which affect the long-term efficacy.

摘要背景：大隐静脉是冠状动脉旁路移植术最常用的血管材料，但移植血管新生内膜增生和随后发生的粥样硬化所致的移植血管狭窄严重影响远期疗效。

Numerically evaluate the value of the largest Lyapunov exponent on diagnosing the various stenosis degrees of internal carotid arteries in white rabbits and in order to diagnose the angiostenosis with transcranial Doppler ultrasound.

Patients had alien hand syndrome (11%), 17 patients had history of hypertention (54.83%) 16 patients had coronary artery heart disease (51.61%), 10 patients had diabetes mellitus (32.25%), 9 patients had history of cerebral infarction (29.03%), 17 patients had disorders of conciousness and mental (54.83%), 18 patients had language disorder (58.1%), 21 patients had disorders of limbs in different degrees (74.19%). MRI imaging of 22 patients showed previous cerebral infarction focuses (70.96%), 16 patients with leukoaraiosis (61%), 9 patients with angiostenosis (29%), stenosis was over 60% in 6 patients, and 7 patients showed cerebral microbleeding (22.58%). There were 34 focus of copus callusum infarctions in 31 patients.

异手综合征者3例(11%)，高血压病史17例(54.83%)，冠心病16例(51.61%)，糖尿病10例(32.25%)，脑梗死史者9例(29.03%)，神志和精神异常的17例(54.83%)，语言障碍的患者18例(58.1%)，21例(74.19%)患者有不同程度肢体运动障碍。31例胼胝体梗死患者，共34处胼胝体梗死病灶，胼胝体梗死的患者合并其它部位陈旧性梗死灶22例(70.96%)，伴有白质稀疏16例(61%)，发现血管狭窄9例（29%，其中狭窄超过60%者6例），有7例(22.58%)伴有微出血。

"Anti-platelet drugs are often used to reduce intima thickening, for example, restenosis...after angioplasty. Perhaps a different method of inhibiting platelet activation would be to drink dealcoholized beer," Dr. Bassus says."Conversely, the acute consumption of alcohol beverages causes an increase of thrombin generation, suggesting a thrombotic risk in case of acute alcoholic intoxication."

抗血小板药物一般被用来降低血管内膜的肥厚症状，如该药物可预防血管修复手术后的血管狭窄现象，Bassus表示，也许抑制血小板活化的另一种方法就是投予去醇啤酒，然而，过度的酗酒反而会造成凝血酵素的增生，也就是说，急性酒精中毒通常会有缺血的风险。

Objective:To evaluate the effectiveness that glutin and VEGF line the injured vasucler wall to prevent the drteries from restenosis.

目的：评价血管重建术后内衬明胶和内皮细胞生长因子受损血管壁对防止血管狭窄的效果。

Methods: After transferred pcDNA3.1/hTM plasmid into rabbit artery by high-pressure injection, rabbit common iliac artery were cut and anastomosed again. At the 14 days and 28days after second operation, we checked inside diameter of anastomotic stoma and blood flow velocity by color Doppler. The treated artery were sliced and stained by Verhoeff. Local neointima formation and the ratio stenosis of intervascular were calculated by computer.

用注射式加压转染的方式对兔动脉壁转染pcDNA3.1/hTM质粒，再制造动脉损伤-阻滞模型，于术后14天、28天用彩色多普勒观察活体吻合口内径和血流流速；再做病理切片Verhoeff染色，观察血管内膜增生的程度、部位，计算血管内膜面积、中膜面积和血管狭窄率。

The accuracy of color ultrasound for stenosis of carotid bifurcation, subclavicular artery and vertebral artery were 93.0%, 92.8% and 82.1%.conclusion color ultrasound examination are effective for the diagnosis of carotid bifurcation sterosis, and less effective for the diagnosis of the subclavicular and vertebral artery stenosis because of the poor sensitivity.

彩色多普勒超声检查诊断颈动脉分叉部、锁骨下动脉和椎动脉狭窄的准确度为93.0%、92.8%和82.1%。结论彩色多普勒超声检查可作为诊断颈动脉分叉部位血管狭窄的有效方法；而其对锁骨下动脉及椎动脉狭窄的敏感性较低，诊断价值不大。
