AbstractThe increasing incidence of morbidly adherent placenta (MAP) is placing women at a higher risk of life-threatening massive hemorrhage. The involvement of interventional radiology to manage this complex condition by performing prophylactic iliac artery balloon occlusion has been reported recently. However, the effectiveness and safety of this technique have not been fully determined. Here we report the case of a 25-year-old woman with placenta increta with preemptive bilateral internal iliac artery balloons who had external iliac artery thrombosis detected by computed tomography angiography (CTA) 72 h post cesarean section. A digital subtraction angiogram (DSA) and intra-arterial thrombolysis were instantly performed followed by supplementary conservative treatments, leading to a desirable resolution of thrombus without sequela. This is the first report of vascular complications with successful interventional thrombolysis in this setting. Our experience suggests that prophylactic iliac artery balloon occlusion should be used cautiously in cases of MAP and consideration given to minimizing vascular complications given the hypercoagulable state of pregnancy.
