阻塞性颅外血管病是老年人最常见的疾病,据Whisnant等氏研究,40％的50岁以上的人,颈部大血管至少有1条有一半以上的狭窄,50岁以上的人,11％有完全的阻塞,常常产生暂时性或永久性的卒中症状:但由于血管外科的进步,当其尚未发展到严重阶段时,有可能重建其循环而获得治愈。为了早期正确地确定病变部位,有必要发展一种造影技术,只经1次操作就可将全部颅内外的大血管同时显影,但目前尚无一种操作容易而又无危险的理想方法。本文将近年来有关此种技术的发展作一综述。由于文献介绍的方法繁多,有些方法又是大同小异或已过时,因此不拟逐一赘述,仅将几种主要而常采用的方法作一综合介绍。1.多次直接穿刺颈动脉及椎动脉,此法早已采用以达到全脑血管造影,近年来已渐被新的方法代替,
Obstructive extracranial vascular disease is the most common disease in the elderly. According to Whisnant et al.’s study, 40% of people over the age of 50 have at least one neck major vessel with more than half of the stenosis, over 50 years of age, and 11 % Complete obstruction, often with temporary or permanent stroke symptoms: but due to advances in vascular surgery, when it has not yet reached a serious stage, it is possible to rebuild its cycle for cure. In order to correctly identify the lesion early in the period, it is necessary to develop an imaging technique that can simultaneously develop all intracranial and extracranial vessels only in a single operation. However, there is no ideal way to operate easily and without risk. This article reviews recent developments in this technology. Since there are many ways to introduce the literature and some of them are similar or outdated, we do not intend to repeat them here. We only introduce a few major and commonly used methods to make a comprehensive introduction. 1. Many times directly puncture the carotid artery and vertebral artery, this method has long been used to achieve whole brain angiography in recent years has gradually been replaced by a new method,
