论文部分内容阅读
在77届北美放射学年会交流内容颇丰,我们就年会中交流的有关血管腔内介入部分论文综合介绍如下: 一.血管成形术 1.血管腔内支撑器 PTA的成功率常因血管弹性退缩,急性闭塞和再狭窄而受限,血管腔内植入支撑器为这些问题提供了解决的方法。支撑器为金属镀钽制成的网状结构,近年临床所用多为Palmaz球囊膨胀式支架。放置部位有胸、腹主动脉,髂动脉、股、膕动脉及腔静脉系统。
In the 77th annual meeting of North American radiology exchange content is quite abundant, we exchange about the endovascular endovascular intervention part of the paper is summarized as follows: 1. Angioplasty 1. Endovascular stent PTA success rate often due to vascular elasticity Retraction, acute occlusion and restenosis are limited, and intraluminal implantation of a brace provides a solution to these problems. Support for the network of tantalum plated metal mesh structure, the clinical use of mostly Palmaz balloon expansion stent. Place the chest, abdominal aorta, iliac artery, femoral, popliteal artery and vena cava system.
