Several methods exist for the estimation of the age at the time of death, ranging from mere visual inspection to costly laboratory examinations. The "combined arteriosclerotic index (CAI)" is considered to be a suitable low-budget tool for undecayed corpses. It defines the ratio between diameter and longitudinal pre-strain of the abdominal aorta. Its applicability in cases of decomposed corpses has not been studied yet. We examined whether it is a valid parameter in putrefied bodies as well and whether there is a correlation between CAI and the stage of decomposition. In conclusion the CAI becomes less accurate with increasing putrefaction. Nonetheless, even in case of high-grade putrefaction it remains a useful tool for instant age estimation which should be followed by the application of methods with higher accuracy.
存在多种估计死亡时年龄的方法，从单纯的肉眼检查到昂贵的实验室检测。“综合动脉硬化指数（CAI）”被认为是一种适用于未腐烂尸体的低成本工具。它定义了腹主动脉直径与纵向预应变之间的比率。其在腐烂尸体案例中的适用性尚未得到研究。我们研究了它在腐败尸体中是否也是一个有效的参数，以及CAI与腐败阶段之间是否存在相关性。总之，随着腐败程度的增加，CAI的准确性会降低。尽管如此，即使在高度腐败的情况下，它仍然是即时年龄估计的有用工具，之后应采用更高准确性的方法。
