Observation vs Embolization in Severe Splenic Injury: A Randomized Controlled Trial

The decision for proximal or distal (selective) embolization is at the discretion of the Interventional Radiologist. For patients with angiographically evident injury, the choice of embolization site will be left to the discretion of the operator. For patients without angiographically evident injury, proximal splenic embolization will be performed with approved materials (coils or plugs for most patients) within the main splenic artery. The embolization endpoint will be hemostasis in the main splenic artery.
