“…[ 55 , 56 ] Likewise resuscitation attempts may introduce free abdominal air that should not be confused with free air caused by intestinal perforation. [ 13 ] Pleural effusion, periportal edema, and distended intestines were also more frequently observed after resuscitation. Postmortem clotting occurred less often in PRS patients and we hypothesize this is caused by anti-coagulation given during resuscitation attempts.…”

ObjectivesTo evaluate the frequency of total-body CT and MR features of postmortem change in in-hospital deaths.Materials and methodsIn this prospective blinded cross-sectional study, in-hospital deceased adult patients underwent total-body postmortem CT and MR followed by image-guided biopsies. The presence of PMCT and PMMR features related to postmortem change was scored retrospectively and correlated with postmortem time interval, post-resuscitation status and intensive care unit (ICU) admittance.ResultsIntravascular air, pleural effusion, periportal edema, and distended intestines occurred more frequently in patients who were resuscitated compared to those who were not. Postmortem clotting was seen less often in resuscitated patients (p = 0.002). Distended intestines and loss of grey-white matter differentiation in the brain showed a significant correlation with postmortem time interval (p = 0.001, p<0.001). Hyperdense cerebral vessels, intravenous clotting, subcutaneous edema, fluid in the abdomen and internal livores of the liver were seen more in ICU patients. Longer postmortem time interval led to a significant increase in decomposition related changes (p = 0.026).ConclusionsThere is a wide variety of imaging features of postmortem change in in-hospital deaths. These imaging features vary among clinical conditions, increase with longer postmortem time interval and must be distinguished from pathologic changes.

“…Postmortem bowel distension presumably occurs because of gas-producing bacteria in the intestinal flora in combination with an absence of intestinal motility. 23,24 Gastrointestinal distension may also occur because of artificial respiration during resuscitation measures. 24,25 Resuscitation measures and artificial respiration were performed in cases 4, 6, 9, and 10 ( Table 1).…”

Bowel distension frequently indicates bowel obstruction, which is a common diagnosis in clinical radiology. Typically, symptoms and complaints lead to radiological examinations and the detection of the etiology. Untreated intestinal obstructions can lead to a fatal outcome through cardiac failure due to septic shock. Certain of these cases undergo medicolegal investigations depending on the case history, the condition of the decedent, the location of the finding, or recent visits to medical professionals. Computed tomography (CT) is a recommended method in clinical radiology for the detection of bowel obstruction, which is indicated by bowel distension and further radiological signs (eg, the whirl sign, which indicates a volvulus). Postmortem CT (PMCT) has increased worldwide, but PMCT differs from clinical CT; thus, the question of whether PMCT is also reliable for the detection of bowel obstruction in decedents or is negatively affected by postmortem modifications should be discussed. This study consists of 10 cases displaying radiological signs of bowel obstruction. Apart from bowel distension, the most common radiological signs (whirl sign, coffee bean sign, bird beak sign, and u-shape sign) are described and depicted. All decedents underwent autopsy and had a postmortem interval of less than 72 hours. Based on these cases, we assess the reliability of PMCT for detecting bowel obstruction and determining its relationship to the cause of death.

Наряду с традиционной аутопсией проведено уже более 80 КТ-исследований тел погибших в случаях механической асфиксии, авиационной травмы, огнестрельной травмы, падения с высоты и утопления, а также заболеваний [22][23][24][25][26][27].…”

This article presents the current state of the issue of diagnostic possibilities of postmortem computed tomography in forensic medicine and clinical disciplines. It was established that in foreign countries and in Russia methods that improve visualization with post-mortem CT were being developed, and correlation between the time since death and postmortem CT artifacts was examined. At present it is advisable to use post-mortem CT as an additional method of research in forensic practice.
