My thought process was that post-partum bleeding is usually related to the uterus, and much of the pelvic viscera is supplied by branches of the internal iliac artery.

neonem  This sounds like a case of acute endometritis. In any case, uterus is supplied by uterine artery (branch of internal iliac artery) with collateral flow from ovarian artery (comes right off aorta). I don't think there are any branches of external iliac artery into the pelvis; it becomes femoral artery once it passes under inguinal ligament. +2
