Abstract/OtherAbstract:
A prospective study was undertaken of 131 perinatal deaths to determine whether gestational age, body weight, maceration degree and autopsy interval influenced successful in vitro tissue culture for cytogenetic evaluation. Perinatal populations were categorized as neonatal death (NND), fresh stillbirth (FSB), or graded as macerated stillbirth (MAC-0, MAC-1, MAC-2, MAC-3). Metaphase production by at least 15 cells separated 'growth' from 'no growth' categories after sampling liver, kidney and spleen. Body weight and degree of maceration were predictive of successful 'growth', while gestational age and autopsy interval were not. Body weight was significant in separating 'growth' from 'no growth' in NND (P = 0.05), FSB, MAC-0 and MAC-1 (P = 0.01). Growth probabilities were 0.78 (NND), 0.57 (FSB), 0.49 (MAC-0), 0.38 (MAC-1) and zero for MAC-2 and MAC-3. We conclude that (a) tissues from MAC-2 and MAC-3 fetuses do not grow and thus need not be sampled at autopsy, (b) maceration degree and body weight can be used to predict the growth probability in the other categories, (c) tissue samples can be taken during daylight hours, since autopsy interval does not influence successful growth provided the fetus is refrigerated at 4 degrees C, (d) all of the above conclusions have cost-efficiency implications for cytogenetic laboratories.
