尸体血管造影技术的发展和趋势

Development and Prospect of Postmortem Angiography Technology

尸体血管造影技术是一种有效的血管检查手段,对探查尸体血管,尤其是心脏、脑部血管的情况具有重要意义。该技术起源于15世纪,发展于18、19世纪。尤其是在发现X线之后,该技术进入了快速发展阶段,无论是在对比剂、灌注方法,还是在成像方法上都取得了巨大的发展。目前,该技术已被广泛应用于实践中。但该技术仍存在一些瑕疵,首先,对比剂仍无法克服渗透弥散、栓塞血管等问题,最理想的对比剂仍未发现;其次,目前的灌注方法仍无法模拟生理血液流动状态。在"保全尸"的宗教和传统观念的指引下,有必要进一步提高目前的造影技术,以满足实践需求。

Postmortem angiography is an effective investigating method of blood vessels. It plays an important role in probing cadaveric vessels, especially for the heart and brain blood vessels. This technology originated from the 15th century, and developed quickly in the 18th and 19th century. Postmortem angiography contains contrast agent, perfusion and imaging, and has made a considerable progress since the discovery of X-ray. At present, this technology has been widely used in practice. However, it still has some defects as follows： First, these contrast mediums still have drawbacks such as permeating, obstruction and so on. Secondly, it is hard to simulate the state of physiological blooding in perfusion. Meanwhile, this technology has been increasingly relied on than ever before, as the religious and traditional ideas of preserving integral corpse. Accordingly, it is essential to improve the postmortem angiography technology to meet the practical need.
