I read with interest the paper by Thon et al. describing the use of prophylactic internal
iliac occlusion balloon catheters in parturients with placenta accreta.
1
The pelvic collateral system is highly interconnected with aortic, internal iliac,
external iliac and femoral components.
2
Most abnormal placentation occurs in the lower uterine segment for which the main
blood supply is by collaterals from the internal pudendal artery.
3
The latter usually arise from the posterior division of the internal iliac artery,
so occlusion of the anterior division of the internal iliac artery is unlikely to
have a hemostatic effect in abnormal lower uterine abnormal placentation.To read this article in full you will need to make a payment
