Abstract］ Objective To evaluate the role of three-dimensional （3D） digital subtraction angiography in the diagnosis and treatment of symptomatic intracranial arterial stenosis.Methods Stent-assisted angioplasty was performed on 30 patients with symptoms of intracranial artery stenosis by 3-dimesion（3D） method.These imagings were reviewed by different locations to get information of optimal projection angle in 2D angiography.

The origin of stenosis of the aqueduct is often unknown, although specific causes of aqueductal stenosis do exist.

导水管狭窄的原因往往不明，尽管确实存在导水管狭窄的特定的原因。

Total laminectomy or half laminectomy would be selected or the nerve root canal was decompressed and hypertrophied ligmentum flavum was removed along with the herriated disc was extirpated if necessary.results all cases were followed from 5 months to 77 months,with an average of 32 months.according to the nakai scale,the results were excellent in 254 cases,good in 41,fair in 5 and poor in none.including 3 cases who had been operated by microendoscopic tubular retractor,and another one had a history of chemonucleolysis.conclusion radiography is very important for suitable selection of surgical indication as well as the operation treatmeat of lumbar disc herniation and lumbar canal stenosis.

结果 术后随访5～77个月，平均32个月，按nakai标准评定疗效：优254例，良41例，可5例（其中在外地做过椎间盘镜术3例，木瓜酶溶核术后1例，而后到本院行此手术），差0例。结论影像学检查为腰椎管狭窄症，黄韧带肥厚的患者，体征与狭窄的定位，在腰椎间盘突出症和腰椎管狭窄症手术方式和适应证的选择上起重要作用。

The other causes included stenosis of the sphincter of Oddi, focalized pancreatitis of the head of pancreas, traumatic stricture of bile duct and stricture of bilioenteric anastomosis (25％), and bile duct obstruction due to tumor (5％).

分析1996—2006年收治的100例多次胆道手术病人的临床资料，对其原因进行分析。结果 65％的胆道再手术原因是结石复发或残留，括约肌狭窄、胰头部肿块型胰腺炎、胆道损伤后狭窄和胆肠吻合口狭窄占26％，胆道系统肿瘤占5％。

Results RAS(defined as ≥50% diameter stenosis) was detected in 22 of the 157 patients (14.01%) and 21 of the 81 patients with coronary artery disease(25.93%) who had at least one coronary artery of ≥50% diameter stenosis, while no RAS was found in patients whose coronary angiograms were normal.

结果 157例患者中，肾动脉狭窄发生率为14.0%；经冠状动脉造影证实的81例冠心病患者中，肾动脉狭窄的发生率为25.9%；冠状动脉造影完全正常的62例患者中，无1例有肾动脉狭窄。

Results: l、The optimal scan parameters for chinese people are flow rate of 3. 0 mL/sec and total injection 125ml. 2、Visibility of coronary arteries and segments: only those proximal and mid segment is image quality sufficient to allow a semiquantitative assessment. 3、Detection of Atherosclerotic Plaque: CT coronary imaging revealed highest sensitivities for the detection of atherosclerotic wall changes the sensitivity of stenoses was 86. 3％. 4、MSCT coronary angiography is easy to prove the entire anatomic structure of coronary and it is an effective technique for evaluating coronary patency. 5、MSCT coronary angiography correctly identified all normal controls and all patients with coronary artery fistula. The anatomic course of the coronary artery fistula was correctly classified. 6、A11 severe lesion could be visualised by

结果：1、不同的扫描技术参数所获得的造影图像质量不同，注射速率3.0ml/s组以及125m1对比剂总量组比较适合国内患者。2、多层螺旋CT冠状动脉造影可显示冠状动脉的主要分支，尤其是冠状动脉的近、中段，显示率在90％以上。3、多层螺旋CT冠状动脉造影对狭窄病变的敏感性为87.3％，能检出冠状动脉造影不易发现的细小斑块，判断狭窄的原因及斑块的特征。4、多层螺旋CT冠状动脉造影可显示搭桥血管的形态、位置及通畅程度，显示桥血管及支架的内腔，安全便捷。5、多层螺旋CT显示冠状动脉畸形准确性高（3/3），多种成像方法可弥补冠状动脉造影显示的不足。6、仿真内窥镜可显示冠状动脉内膜和内腔，显示狭窄斑块的性质。

Results Reconstructive coronary artery images of 1 patient with severe sinus arrhythmia were not displayed clearly.

结果 在56例行MSCT冠状动脉造影的患者中1例由于患者有严重的窦性心率不齐，重建图像质量欠佳，其余患者均成功显示冠状动脉各主支（左主支、回旋支、前降支右支冠状动脉）及部分3、4级分支，且可显示所有冠状动脉支架的形态、位置，其中18例患者的31个支架术后出现再狭窄，所有行MSCT冠状动脉造影检查的患者无一例出现并发症，所有CT诊断支架术后再狭窄的患者同时行选择性血管造影检查，其中14例患者的25个支架有支架术后再狭窄，CT诊断的准确率为80.65%。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
