Factors Contributing to Massive Blood Loss on Peripartum Hysterectomy for Abnormally Invasive Placenta: Who Bleeds More?

Table 1

Patients’ backgrounds of AIP-hysterectomy group versus control group.

	Hysterectomy for AIP ()	Control ( = 11,901)	value
Age (years)	36.8 ± 4.7	31.9 ± 5.3	<0.001
Multiple pregnancy	1 (5.6%)	970 (8.2%)	1.000
GA at delivery (week)	35.1 ± 2.2	38.0 ± 2.9	<0.001
Blood loss (mL)	6,655 ± 3,798	635 ± 561	<0.001
Birth weight (g)	2,261 ± 452	2,707 ± 644	<0.001
CS	18 (100%)	5,768 (48.5%)	<0.001

AIP: abnormally invasive placenta, CS: cesarean section, and GA: gestational age.
The -test and Fisher’s exact test are applied.
