Abstract

Postmortem angiography is becoming increasingly essential in forensic pathology as an adjunct to conventional autopsy. Despite the numerous advantages of this technique, some questions have been raised regarding the influence of the contrast agent injected on the results of toxicological and biochemical analyses. The aim of this study was to investigate the effect of the injection of the contrast agent Angiofil®, mixed with paraffin oil, on the results of postmortem biochemical investigations performed on vitreous humor. Postmortem biochemical investigations were performed on vitreous samples collected from bodies that had undergone postmortem angiography (n=50) and from a control group (n=50). Two vitreous samples were analyzed for each group and the results compared. Glucose, urea, creatinine, 3-β-hydroxybutyrate, sodium and chloride were tested. Different values were observed between the first and second samples in each group. However, these differences were not clinically relevant, suggesting that the injection of this contrast agent mixture does not modify the concentration of the analyzed substances in the vitreous humor.
