The next time you find yourself wondering why the literature on a particular adopted but slight iffy intervention suddenly goes quite this article might offer some explanation:

It is something that, when combined with point of care ultrasound, becomes appealing for pre-hospital application. However, as Deborah presents, while there is a lot of potential gain from REBOA, there is also a lot yet that needs clarification before rushing in:
