“…If the circumstances indicate a possible air embolism, Knight [7] recommends as the first step a pre-autopsy chest radiograph, which can reveal larger quantities of air in the heart and the blood vessels [8,9]. This is also necessary in cases of barotrauma [7].…”

Venous air embolism is a rare cause of death. Entry of gas into the circulation is caused by trauma, mostly surgical or therapeutic, and sometimes resulting from criminal intervention. The detection of air embolisms requires special precautions during autopsy. An aspirometer has to be used for the detection, measurement and storage of gas originating from the heart ventricles. The aspirometer has to be filled completely with distilled water containing two drops of Tween 80 to reduce the surface tension of the water and to prevent adherence of small air bubbles to the wall of the aspirometer. Subsequently the gas has to be analysed by gas chromatography. When the results correspond with the main criteria defined by Pierucci and Gherson [2] the diagnosis "air embolism" is justified. The technique for the detection of air embolism is simple but requires a careful procedure which is described in detail.

“…According to Frey [19], air embolism is defined as the penetration of gas into the vascular system and its diversion due to blood flow. Most commonly, gas enters the venous system due to a lesion that exposes a vein.…”

Distribution of artifactual gas on post-mortem multidetector computed tomography (MDCT)

et al. 2011

Purpose We investigated the incidence and distribution of post-mortem gas detected with multidetector computed tomography (MDCT) to identify factors that could distinguish artifactual gas from cardiac air embolism. Material and methods MDCT data of 119 cadavers were retrospectively examined. Gas was semiquantitatively assessed in selected blood vessels, organs, and body spaces (82 total sites). Results Seventy-four of the 119 cadavers displayed gas (62.2%; CI 95% 52.8-70.9), and 56 (75.7%) displayed gas in the heart. Most gas was detected in the hepatic parenchyma (40%), right heart (38% ventricle, 35% atrium), inferior vena cava (30% infrarenally, 26% suprarenally), hepatic veins (26% left, 29% middle, 22% right), and portal spaces (29%). Male cadavers displayed gas more frequently than female cadavers. Gas was detected 5-84 hours after death; therefore, the post-mortem interval could not reliably predict gas distribution (rho=0.719, p<0.0001). We found that a large amount of putrefaction-generated gas in the right heart was associated with aggregated gas bubbles in the hepatic parenchyma (sensitivity=100%, specificity=89.7%). In contrast, gas in the left heart (sensitivity=41.7%, specificity=100%) or in periumbilical subcutaneous tissues (sensitivity=50%, specificity=96.3%) could not predict gas due to putrefaction. Conclusion This study is the first to show that the appearance of post-mortem gas follows a specific distribution pattern. An association between intracardiac gas and hepatic parenchymal gas could distinguish between post-mortem-generated gas and vital air embolism. We propose that this finding provides a key for diagnosing death due to cardiac air embolism.
