[fest]

Yes, at least that's what I've been told by ultrasound techs on two separate occasions (one tech even told she has seen cases where repeated damage has been done to one of the spleens, the damaged one was taken out and the other one has taken over the primary function).

Apparently this is the current medical consensus in my country- if the spleen is ruptured but not causing massive internal bleeding, the course of action is to monitor patient to see if it heals on it's own. In my case the ruptured part formed scar tissues around it, separating itself from the original spleen.
