Coronary re-permealization by percutaneous transluminal coronary angiography in 100 patients with ischemic heart disease

The author carried out balloon angioplasty on native coronaries or venous saphena bypass grafts by 100 ischemic patients (67 males, 33 females). Previously 57 patients had myocardial infarction and 12 patients went through aorto-coronary bypass grafting. In all cases indicating the proper therapy mainly the angiologic state of coronary arteries was considered. Per patient 2.1 significant stenoses or occlusions were dilated with 90% angiologic, 91% clinical success rate. By 3 patients in one dilated coronary artery occurred therapy resistant thrombosis and secondary necrosis. One patient went through emergency bypass grafting, two patients died. The careful, clinical follow up has an important role in the first 6 months. During this period the restenoses must be recognized and we have to decide how to treat the patient correctly.     

急性下壁心肌梗死并发泵衰竭的临床特征和冠状动脉造影特点分析

目的探讨急性下壁心肌梗死并发泵衰竭的临床特征和冠状动脉解削、病变特点。方法选择2002年1月。2007年4月住院治疗的急性下壁心肌梗死并发泵衰竭患者（泵衰竭组）28例和不合并泵衰竭患者（对照组）60例，对其临床资料和冠状动脉造影资料进行回顾性分析。结果泵衰竭组平均年龄高于对照组（P〈0．05），经典冠心病危险因素≥2个者多于对照组（P〈0．05），稳定型心绞痛病史、梗死后心绞痛、合并后壁梗死发生率高于对照组（P〈0．05），肌酸激酶同工酶MB峰值高于对照组（P〈0．05），快速心律失常、胸前导联ST段压低发生率高于对照组（P〈0．05），住院时间和院内病死率高于对照组（P〈0．05），冠状动脉造影显示右冠状动脉超优势分布、合并前降支狭窄〉75％病变、右向左侧支循环建立高于对照组（P〈0．05）。结论急性下壁心肌梗死并发泵衰竭有一定的易患因素和临床特征，早期成功恢复心肌再灌注是治疗的关键。

目的 探讨急性下壁心肌梗死并发泵衰竭的临床特征和冠状动脉解剖、病变特点.方法 选择2002年1月～2007年4月住院治疗的急性下壁心肌梗死并发泵衰竭患者(泵衰竭组)28例和不合并泵衰竭患者(对照组)60例,对其临床资料和冠状动脉造影资料进行回顾性分析.结果 泵衰竭组平均年龄高于对照组(P＜0.05),经典冠心病危险因素≥2个者多于对照组(P＜0.05),稳定型心绞痛病史、梗死后心绞痛、合并后壁梗死发生率高于对照组(P＜0.05),肌酸激酶同工酶MB峰值高于对照组(P＜0.05),快速心律失常、胸前导联ST段压低发生率高于对照组(P＜0.05),住院时间和院内病死率高于对照组(P＜0.05),冠状动脉造影显示右冠状动脉超优势分布、合并前降支狭窄＞75%病变、右向左侧支循环建立高于对照组(P＜0.05).结论 急性下壁心肌梗死并发泵衰竭有一定的易患因素和临床特征,早期成功恢复心肌再灌注是治疗的关键.     

螺旋CT与核磁脑血管成像的临床价值

目的探讨64排螺旋CT血管成像（CTA）与3T核磁血管成像（MRA）在脑血管疾病中的临床应用价值。方法对46例脑血管疾病患者均行64排螺旋CT血管成像与3T核磁血管成像检查。结果 64排螺旋CT血管成像检出脑动脉瘤38例,脑动脉畸形2例,3T核磁血管成像检出脑动脉瘤34例,脑动脉畸形2例,且瘤体的大小存在差异;脑动脉狭窄或闭塞64排螺旋CT血管成像检出21例,3T核磁血管成像检查26例,血管狭窄的程度也不一致。结论在脑血管疾病检查中,64排螺旋CT血管成像技术与3T核磁血管成像技术均为无创性血管检查,CTA对于脑动脉瘤准确率较高,但颅底位置容易漏诊。MRA对于过小动脉瘤容易漏诊;CTA对钙化和软斑块显示比较好,M RA可以较好的显示血流方向以及血管功能方面的信息。     

Digital subtraction angiography

Digital Subtraction is a computerised radiological technique to demonstrate the vascular tree by removing unwanted background information and enhancing dilute contrast medium within the blood vessels. Contrast may be introduced intravenously or intra-arterially. The relative merits of these two methods, together with the advantages and limitations of the technique are discussed.
