血管狭窄

Results 45 infarct related arteries among 40 cases acquired coronary artery repatency with TIMI 3 degree flow, a success rate of 95.2%(40/42), the residual stenosis in repatency coronary arteries was from 0 to 20%. The clinic symptom of the 5 cases with left ventricular dysfunction and 2 of the 3 cases with cardiogenic shock were obviously improved, 1 case(2.5%) with cardiogenic shock was dead in hospital.

结果 40例患者中的45支梗塞相关血管获得再通，成功率达95.2%(40/42)，均达到TIMI-3级血流灌注，再通血管残余狭窄0%～20%。5例合并左心功能不全(Killip分级Ⅱ～Ⅲ级)及3例合并心源性休克患者术后症状明显改善，住院期间1例死亡(病死率2.5%)。

Methods and Results-: We enrolled 142 patients randomized at a single center to have either the radial artery or saphenous vein grafted to a stenosed branch of the native left circumflex coronary artery. The primary end point was angiographic graft patency 5 years postoperatively.

方法和结果：我们通过单中心随机试验对左冠状动脉狭窄进行桡动脉或隐静脉移植的142例病人进行研究，主要的终点利用血管造影对移植的血管进行监测5年。

The vessel diameter, vessel area, diameter of reference vessel rate of stenosed area and lesion length detected by three-dimensional reconstruction coronary angiography and QCA were compared.

分析比较冠状动脉3D重建和QCA传统平面图像对靶病变管腔直径和面积、参考血管直径、面积狭窄率、病变血管长度的测量值。

Objective To evaluate different magnetic resonance angiography sequences in detecting peripheral vascular disease by means of a study in vitro with an arterial stenotic model.

目的通过多种磁共振血管造影技术对模拟狭窄血管的体外模型和四肢血管性疾病应用研究分析，评估其临床应用价值和限度。

In NCD group, 147 arteries were detected. Only 1 stenotic artery was diagnosed by both TCD and CVA.

非闭塞性脑血管病组共检出血管147条，TCD检出狭窄血管1条与DSA结果一致。

Results: In these patients, MSCTA identified 92 arterial segments to have varied degrees of stenosis or occlusion, which included 22 cases of arteriosclerosis obliterans of lower extremity (involving the abdominal aorta in 1 patient, iliac artery in 2, femoral or popliteal artery in 8, lower leg artery in 4 and full-limb vascularity in 7), 5 cases of thromboangiitis obliterans (TAO, involving the common iliac artery in 3 patients and external iliac artery in 2), and 5 cases of Takayasu's arteritis.

结果：32例患者下肢血管疾病多层螺旋CT血管成像检查中，共发现92个动脉节段不同程度的狭窄甚至闭塞。

Fourpatientswere diagnosedfree ofASO,and 55 patients exhibited discontinued sclerosis orblock of lower extremity arteries around whichwere plenty ofblood-supply peripheral arteries.Conclusion 64-slice CT angiography can display the featuresof lower extremity arteries clearly,such as vasiform,arterial stenosis degree,occlusion and calcified plaque.

64层螺旋CT血管成像检查可清楚地观察下肢动脉的血管形态及管壁的钙化斑块，了解下肢动脉狭窄程度及闭塞情况，对下肢动脉硬化性闭塞性病变的术前评价、诊断和筛选有较大的帮助。

Also, take steps to keep your circulation healthy: Avoid cigarettes and caffeine, both of which narrow blood vessels; stay away from vasoconstricting meds such as decongestants; and hit the gym regularly.

还有，采取办法保持你的血液健康循环：避免吸烟和咖啡因，两者都会使血管变的狭窄；远离收缩血管的药物，例如解充血药物；并定期锻炼。

In patients with RP, the concentration of VEGF-A in aqueous humors is lower than in non-RP subjects.

缺乏VEGF-A的促血管生成作用，可能会解释RP的某些临床表现，比如视网膜血管的狭窄和纤维化变性。

Results Four cases were with straight and no press,2 of 4 cases with spasm;5 with kinking and no stenosis;10 with kinking and stenosis;and 1 with deformtion.

结果 椎动脉平直，无压迫4例，其中2例血管痉挛变细；椎动脉迂曲改变，无血管受压5例；椎动脉迂曲、狭窄，明显受压10例；畸形1例。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
