The utilization of lower limbs rSO₂ in intra-aortic balloon occlusion for placenta previa accreta

Abstract

 【Objective】We use intra-aortic balloon occlusion（IABO）when performing cesarean hysterectomy（CH）for placenta accreta spectrum at our hospital. During CH, we monitor regional oxygen saturation（rSO₂）using INVOS^TM（Medtronic. Ireland）to evaluate blood flow in the lower limbs. We investigated the usefulness of lower limbs rSO₂ in cases with IABO.

 【Methods】We targeted 21 cases in which placenta accrete spectrum was suspected and IAB was placed at our hospital. We investigated lower limbs rSO₂ during CH and the presence or absence of complications retrospectively.

 【Results】CH was performed in 13 of the 21 cases in which IAB was placed. In the other 8 cases, we did not extract uterus. There was significant differences in the average value of lower limb rSO₂（p ＜ 0.0001）. No complications occurred in all cases.

 【Conclusion】It is possible to monitor lower limbs rSO₂ during IABO when placenta accreta spectrum is suspected.
