作者于1980年采用Gruntzig式气囊导管法,经皮插入冠状动脉狭窄部,注入造影剂泛影葡胺扩张冠状动脉,用以治疗心绞痛取得显著效果。所用导管型号有3毫米和3.7毫米,长度有12毫米和20毫米,根据冠状动脉狭窄部位和程度分别选用。对象和适应症:对应用各种抗心绞痛药物不能控制的心绞痛病例,又不适宜作冠状动脉分流术(pypass)者,具备以下条件可施行冠状动脉扩张术:(1)4号探针(probe)导管能通过狭窄部;(2)狭窄部长度在20mm以内;(3)狭窄部没有显著的钙化;(4)左冠状动脉主干部狭窄为局限性者。方法和效果:用7号Jadkins导管,术前给予硝酸甘油0.3mg含于舌下,利多卡因50mg,肝素5,000单位静注后,再用Gruntzig式气囊导管插入狭窄部进
The author in 1980 using Gruntzig balloon catheter method, percutaneous insertion of coronary stenosis, injection of contrast agent diatrizoate meglumine diastolic coronary artery for the treatment of angina achieved remarkable results. The catheters used are 3 mm and 3.7 mm in length and 12 mm and 20 mm in length, respectively, depending on the site and extent of coronary stenosis. Subjects and indications: The use of a variety of anti-angina drugs can not control the angina cases, but not suitable for coronary bypass (pypass) who have the following conditions can be performed coronary artery dilatation: (1) probe 4 ) The catheter can pass through the stenosis; (2) the stenosis length is within 20 mm; (3) the stenosis has no significant calcification; and (4) the stenosis of the left coronary artery is limited. Methods and Results: Using a 7-gauge Jadkins catheter, 0.3 mg of nitroglycerin was subcutaneously administered sublingually, lidocaine 50 mg, and heparin 5,000 units intravenously followed by a Gruntzig balloon catheter for stenosis
