Formula to Predict Platelet Count after Partial Splenic Arterial Embolization in Patients with Hypersplenism

These data suggest that platelet count after PSE can be predicted before the procedure by using the Vh/Vsp ratio and the anticipated spleen embolization volume. The use of such a prediction can prevent too much or too little embolization, thereby leading to an improvement in the risk/return trade-off in PSE.
