Is the Perinatal Outcome of Placental Abruption Modified by Clinical Presentation?

Table 4

The histological study of women complicated with placental abruption among groups of HT, TPL/ROM, and clinically low risk.

	HT	TPL/ROM	Clinically low risk
Number	22	35	27
(No histological records)	(6)	(4)	(3)
Chorioamnionitis (%)	1 (6%)*	12 (39%)	3 (13%)*
Ischemic changes (%)	7 (44%)	7 (23%)	3 (13%)^†
Infarcts (%)	5 (31%)	3 (10%)	10 (42%)*

Results are expressed as Mean ± SD or incidence (%). HT: pregnancy-induced hypertension and TPL/ROM: threatened premature labor and/or premature rupture of membrane.
