Brief Summary: Our aim is to conduct a multi-center Bayesian randomized clinical trial to evaluate the primary technical success of coils and vascular plugs for proximal splenic artery embolization in the setting of high-grade splenic trauma The investigator has previously demonstrated the feasibility of such a study in a single center pilot trial
Detailed Description: Splenic preservation rates are improved for participants with high-grade splenic injuries defined as Grade III-V injuries by the American Association for the Surgery of Trauma AAST guidelines when non-operative management is supplemented by image-guided trans-catheter splenic artery embolization SAE SAE is currently the standard of care for hemodynamically stable participants with high-grade splenic injuries In proximal SAE pSAE the mid-splenic artery is embolized between the origins of the dorsal pancreatic artery and pancreatica magna artery with either endovascular plugs VPs or endovascular coils EC This reduces the intra-splenic arterial pressure which allows the parenchyma time to heal Splenic perfusion is maintained via a collateral pathway consisting of flow from the splenic artery proximal to the site of embolization through the smaller dorsal pancreatic artery to the transverse pancreatic artery to the pancreatica magna artery which then delivers a slower smaller amount of blood to the splenic artery distal to the site of embolization Additionally collateral supply from the short gastric and gastroepiploic arteries helps to protect the spleen from infarction andor abscess formation

pSAE is most often accomplished using either VPs or ECs as the embolic agent both of which are FDA-approved and clinically-available ECs have a long history of efficacy and safety for embolization and are thus familiar embolic agents to most endovascular specialists Further coils large enough to embolize the mid-splenic artery can be deployed through a standard micro-catheter which means they can be used in even the most tortuous splenic arteries However multiple coils may need to be deployed in the same patient to achieve hemostasis in the mid-splenic artery that may increase their overall cost iodinated contrast use procedural time and the radiation exposure to the participant and medical staff Additionally given the high-flow nature of the splenic artery even an appropriately sized coil may migrate distally A typical pSAE using coils will involve the deployment of one helical coil followed by multiple packing coils until hemostasis is achieved VPs attempt to overcome the limitations of coils For example the deployment of a single VP can typically provide hemostasis in the mid-splenic artery which theoretically reduces procedural time contrast load and radiation exposure Despite this VPs are usually more expensive than coils on a per unit basis and are usually less familiar devices to endovascular specialists Another drawback of VPs is that they cannot be deployed through a standard micro-catheter but rather require the advancement of a larger stiffer 0035 inch system into the mid-splenic artery This may limit their use in very tortuous splenic arteries Currently the selection of embolic agent for pSAE is primarily based on operator experience and preference The embolic efficacy technical success and cost of using coils compared to VPs has been evaluated in other diseases yet to the best of our knowledge these embolic agents have never been compared for their use in pSAE much less in a randomized prospective fashion
